| 4 | |
| 5 | libzvbi 0.2.32, 2008-08-20 |
| 6 | -------------------------- |
| 7 | This version adds a new tool named zvbi-atsc-cc to record Closed |
| 8 | Caption from ATSC digital TV. It supports legacy NTSC caption |
| 9 | (EIA 608-B) and DTVCC (CEA 708-C). |
| 10 | |
| 11 | libzvbi 0.2.31, 2008-07-26 |
| 12 | -------------------------- |
| 13 | The vbi_caption_unicode() function did not correctly translate |
| 14 | the small letter i with diaresis. |
| 15 | |
| 16 | The files daemon/chains.c, daemon/proxyd.c, |
| 17 | test/proxy-test.c and test/cc-test-stream.dtd are now licensed |
| 18 | under GPLv2 or later as stated in the top README file. |
| 19 | |
| 20 | libzvbi 0.2.30, 2008-03-05 |
| 21 | -------------------------- |
| 22 | This is a bugfix release restoring the functions vbi_unref_page(), |
| 23 | vbi_is_cached() and vbi_cache_hi_subno() which were accidentally |
| 24 | dropped in libzvbi 0.2.28. |
| 25 | |
| 26 | libzvbi 0.2.29, 2008-02-24 |
| 27 | -------------------------- |
| 28 | This version fixes incompatibilities with strict ISO C in the |
| 29 | libzvbi header file. |
| 30 | |
| 31 | libzvbi 0.2.28, 2008-02-22 |
| 32 | -------------------------- |
| 33 | The ZVBI libraries libzvbi and libzvbi-chains are now licensed under |
| 34 | the terms of the GNU Library General Public License version 2 or |
| 35 | later. Example programs are now licensed under a 2-clause BSD-style |
| 36 | license. The VBI proxy daemon, contributed programs, test programs |

| 39 | |
| 40 | Bug fixes: |
| 41 | - A Teletext Level 2.5 transparency attribute bug was fixed in |
| 42 | the teletext decoder. |
| 43 | - The capture test tool did not work with DVB devices. |
| 44 | |
| 45 | Other changes: |
| 46 | - The VTX export module has been disabled for licensing reasons. It |
| 47 | may return after a rewrite. |
| 48 | - New BCD functions and vbi_ham24p(), counterpart of vbi_unham24p(), |
| 49 | were added. |
| 50 | - The artificial 41st column in Teletext pages is no longer black |
| 51 | but continues the previous column if appropriate. |
| 52 | - The --default-cs option of the export test tool now works with |
| 53 | libzvbi 0.2 as well. |
| 54 | |
| 55 | libzvbi 0.2.27, 2008-02-14 |
| 56 | -------------------------- |
| 57 | This is a bugfix release. |
| 58 | |
| 59 | - The DVB VBI demultiplexer entered an endless loop on some input. |
| 60 | - The Closed Caption special character conversion did not work. |
| 61 | |
| 62 | libzvbi 0.2.26, 2007-11-27 |
| 63 | -------------------------- |
| 64 | - The experimental DVB VBI multiplexer was improved and support for |
| 65 | raw VBI data was added. It is now part of the API. |
| 66 | - The bit slicer was improved to give better results with noisy |
| 67 | Closed Caption signals and the capture device simulator can now |
| 68 | simulate noisy signals. Thanks go to Rich Kadel for testing. |
| 69 | - Tom Zoerner contributed an XPM export module and added support for |
| 70 | an 8-bit indexed format to the Teletext page rendering functions. |
| 71 | The PNG and PPM modules work a little more efficiently now. Two |
| 72 | functions were added to export Teletext and Closed Caption pages |
| 73 | into memory instead of an i/o stream or file. |
| 74 | |
| 75 | Bug fixes: |
| 76 | - The V4L2 capture interface did not properly initialize the |
| 77 | parameters for VIDIOC_QBUF and VIDIOC_DQBUF ioctl calls. It also |
| 78 | failed to resume capturing after the bttv driver returned an EIO |
| 79 | error. |
| 80 | - The DVB capture interface did not work with all drivers because |
| 81 | the device file was opened for reading and writing. |
| 82 | - The vbi_sliced_name() and vbi_sliced_payload_bits() functions |
| 83 | returned nothing for VBI_SLICED_TELETEXT_B_L25_625. |
| 84 | - The Teletext decoder permitted double width characters in the |
| 85 | last column. |
| 86 | - In the vbi_pfc_demux_cb function prototype the second and third |
| 87 | parameter were swapped. Fix by Tom Zoerner. |
| 88 | - The vbi_decoder_delete function did not free the event handler list. |
| 89 | - The text and HTML export modules did not free some internal data on |
| 90 | errors. |
| 91 | |
| 92 | The test tools were improved: |
| 93 | - All tools now support a --verbose option for debugging, and --quiet, |
| 94 | --help, --usage and --version options. |
| 95 | - The capture tool can now generate DVB VBI PES and TS streams with |
| 96 | variable packet size to reduce the number of stuffing bytes, and |
| 97 | user defined TS PID. An -o output file option was added. New device |
| 98 | simulation options were added and raw VBI capturing is now possible. |
| 99 | Capturing through the VBI proxy was added by Tom Zoerner. The |
| 100 | timestamps in the output were incorrect if a frame contained no |
| 101 | data, this was fixed. |
| 102 | - The decode tool now accepts DVB VBI PES and TS streams and an -i |
| 103 | input file option was added. IDL-A decoding works again. |
| 104 | - The export tool now accepts DVB VBI PES and TS streams and an -i |
| 105 | input file option was added. It can now export multiple pages, has |
| 106 | a new -o output file option, and can list the possible file formats |
| 107 | and conversion options. |
| 108 | - The sliced2pes tool now also accepts DVB VBI PES and TS streams, has |
| 109 | a new -i input and -o output file option, and can produce DVB VBI |
| 110 | PES and TS streams with user defined packet size, data_identifier |
| 111 | and TS PID. |
| 112 | - The ttxfilter tool accepts DVB VBI PES and TS streams, has a new -i |
| 113 | input and -o output file option. A time option was added to cut |
| 114 | Teletext (esp. subtitle) streams. Various bugs were fixed. |
| 115 | - Courtesy of Tom the osc tool can now capture raw data through the |
| 116 | VBI proxy. |
| 117 | - Raw VBI capturing with the proxy-test tool works again, also fixed |
| 118 | by Tom. |
| 119 | |
| 120 | Build fixes: |
| 121 | - The package did not compile with ./configure --disable-static |
| 122 | (bug #1692015). |
| 123 | |
| 124 | libzvbi 0.2.25, 2007-03-09 |
| 125 | -------------------------- |
| 126 | This version fixes a buffer overflow bug in the zvbi-ntsc-cc |
| 127 | tool which may cause a segfault on reception errors. Secondly it |
| 128 | fixes a GNU/kFreeBSD compile problem (Debian bug #407621). |
| 129 | |
| 130 | libzvbi 0.2.24, 2006-11-29 |
| 131 | -------------------------- |
| 132 | This version fixes a bug in the zvbi-ntsc-cc tool which may cause |
| 133 | a segfault on reception errors. |
| 134 | |
| 135 | libzvbi 0.2.23, 2006-10-27 |
| 136 | -------------------------- |
| 137 | This versions adds a few helper functions to convert Closed Caption |
| 138 | and UCS-2 strings. The raw VBI decoder was modified to handle a CC |
| 139 | signal with incorrect clock run-in. |
| 140 | |
| 141 | The zvbi-ntsc-cc tool can now decode all caption channels |
| 142 | simultaneously and convert from caption to locale character encoding |
| 143 | for proper display of Spanish captions. It can write caption and XDS |
| 144 | information to separate files. Some bugs in the XDS decoder were fixed |
| 145 | and a filter was added to discard unwanted XDS information and WebTV |
| 146 | links. |
| 147 | |
| 148 | Fixes: |
| 149 | - The library did not compile on GNU/kFreeBSD due to a name space |
| 150 | conflict with the RAW macro (Debian bug #372302). |
| 151 | |
| 152 | libzvbi 0.2.22, 2006-05-30 |
| 153 | -------------------------- |
| 154 | This version adds a simulated raw and sliced VBI capture device |
| 155 | to debug applications. The VBI simulation in the capture and osc |
| 156 | tools is more accurate and VPS signals can be simulated. Functions to |
| 157 | convert sliced VBI data to raw VBI images are public now and an example |
| 158 | application was added. An interface to enable warning and debugging |
| 159 | messages was added. |
| 160 | |
| 161 | Fixes: |
| 162 | - Bit slicing of WSS data started a little early. It should work |
| 163 | better now with noisy signals. |
| 164 | - The WSS capture example used an incorrect bytes-per-line value. |
| 165 | - A work-around for a line allocation bug in older versions of |
| 166 | the bttv driver was added. Enables capturing of single lines |
| 167 | (VPS, WSS, CC). |
| 168 | |
| 169 | libzvbi 0.2.21, 2006-05-10 |
| 170 | -------------------------- |
| 171 | This is a bugfix release. |
| 172 | |
| 173 | - Capturing WSS data from video images failed due to a broken check |
| 174 | in the raw VBI decoder. |
| 175 | |
| 176 | libzvbi 0.2.20, 2006-05-08 |
| 177 | -------------------------- |
| 178 | This version supports raw VBI capturing with unknown field order, adds |
| 179 | a work-around for a VBI offset bug in the bttv driver, enables |
| 180 | additional debugging messages and improves some test tools. Network |
| 181 | identification now returns CNIs and a network identification example |
| 182 | was added. The CNI (networks) table was updated. |
| 183 | |
| 184 | libzvbi 0.2.19, 2006-02-23 |
| 185 | -------------------------- |
| 186 | This is a bugfix release. |
| 187 | |
| 188 | - Due to a preprocessor mishap zvbi-ntsc-cc did not use libzvbi but |
| 189 | its own VBI decoder. |
| 190 | |
| 191 | libzvbi 0.2.18, 2006-02-11 |
| 192 | -------------------------- |
| 193 | This is a bugfix release. |
| 194 | |
| 195 | - The configure script has been modernized. Building from CVS now requires |
| 196 | automake 1.9, autoconf 2.59 and gettext 0.14. |
| 197 | - Diego Pettenò added a configure option to disable documentation |
| 198 | building regardless if doxygen is installed. |
| 199 | - After make clean src/Makefile tried to rebuild network-table.h from |
| 200 | http://zapping.sourceforge.net/zvbi-0.3/networks.xml and other |
| 201 | source files. This make rule was only intended for the maintainer. |
| 202 | - A pointer aliasing bug in the linked list implementation of the |
| 203 | Teletext cache, which may crash applications, has been fixed. |
| 204 | - In previous versions GCC may not have inlined some bit slicer and |
| 205 | page rendering functions, making them much slower. |
| 206 | - The teletext filter added in 0.2.17 did not work with parallel page |
| 207 | transmission (e.g. BBC). |
| 208 | - The code was cleaned up to muffle compiler warnings (Diego). |
| 209 | |
| 210 | libzvbi 0.2.17, 2005-10-07 |
| 211 | -------------------------- |
| 212 | This version adds missing XDS packet subclasses to the XDS |
| 213 | demultiplexer. The contrib directory now contains a version of the |
| 214 | ntsc-cc Closed Caption decoder from the Xawtv package using libzvbi |
| 215 | for driver access and bit slicing. It installs as zvbi-ntsc-cc. The |
| 216 | CNI (networks) table was updated. The test tools were cleaned up |
| 217 | and a teletext filter was added. |
| 218 | |
| 219 | Fixes: |
| 220 | - The DVB multiplexer didn't work right (used by test tools only, |
| 221 | not part of the API yet). |
| 222 | - The ioctl logger (test stuff) didn't log VIDIOC_G_STD |
| 223 | and VIDIOC_S_STD. |
| 224 | - test/decode option -a didn't work. |
| 225 | |
| 226 | libzvbi 0.2.16, 2005-05-25 |
| 227 | -------------------------- |
| 228 | This version adds a new demultiplexer to extract XDS data from a |
| 229 | caption stream (EIA 608). |
| 230 | |
| 231 | Fixes: |
| 232 | - test/caption, test/osc did not compile due to a bug in the |
| 233 | configure script. |
| 234 | - Removed a misplaced assertion in vbi_capture_io_update_timeout(). |
| 235 | - test/osc, test/capture, test/wss -d option segfaulted. |
| 236 | - Fixed NTSC VBI capturing in the Linux saa7134 0.2.13 driver and |
| 237 | added a partial work-around here for older versions. |
| 238 | - The HTML export module segfaulted. Fix by Bernhard Rosenkraenzer. |
| 239 | |
| 240 | libzvbi 0.2.15, 2005-03-28 |
| 241 | -------------------------- |
| 242 | This is a bugfix release. Due to an incorrect bytes per line check |
| 243 | previous versions could not capture VBI data from the ivtv driver. |
| 244 | |
| 245 | libzvbi 0.2.14, 2005-02-28 |
| 246 | -------------------------- |
| 247 | This version adds new demultiplexers to extract data transmissions |
| 248 | from Teletext streams, namely in "Page Format Clear" format (e.g. |
| 249 | NexTView EPG) and "Independent Data Line Format A". A new low-level |
| 250 | decoding tool was added for tests. |
| 251 | |
| 252 | libzvbi 0.2.13, 2005-01-23 |
| 253 | -------------------------- |
| 254 | This version has new, more reliable DVB VBI capture routines. See |
| 255 | the documentation of vbi_capture_dvb_new() for details. |
| 256 | |
| 257 | Fixes: |
| 258 | - vbi_capture_bktr_new() ignored the scanning parameter, always |
| 259 | assuming 625 line systems (e.g. PAL-BGHI, SECAM-L). |
| 260 | - Include fix in test/wss.c. |
| 261 | - vbi_unham8() return type signedness fix. |
| 262 | - GCC 4.0 compile fixes. |
| 263 | |
| 264 | libzvbi 0.2.12, 2005-01-18 |
| 265 | -------------------------- |
| 266 | Various error correction functions, generator and bit reversal |
| 267 | functions useful for VBI decoding are public now. A new test app |
| 268 | has been added to capture WSS data from video images. French |
| 269 | translation update by Christian Marillat. |
| 270 | |
| 271 | Bttv drivers 0.9.0 - 0.9.15 report wrong PAL/SECAM field 2 line numbers. |
| 272 | A work-around has been added, and a bug compatible Teletext data |
| 273 | service table entry has been corrected. |
| 274 | |
| 275 | If you encounter problems using similarly broken drivers please try a |
| 276 | fuzzy match of driver capabilities and data service parameters (e.g. |
| 277 | vbi_capture_v4l2_new(strict <= 1)) and notify mschimek@users.sf.net. |
| 278 | |
| 279 | The test/capture and test/osc apps did not capture PAL/SECAM line 23 |
| 280 | (WSS), this has been fixed. |
| 281 | |
| 282 | libzvbi 0.2.11, 2004-12-31 |
| 283 | -------------------------- |
| 284 | Build fix. Cough. |
| 285 | |
| 286 | libzvbi 0.2.10, 2004-12-30 |
| 287 | -------------------------- |
| 288 | The bit slicer and raw VBI decoder have been replaced by improved and |
| 289 | better tested versions. Developers please note: memory will leak if |
| 290 | you do not call vbi_raw_decoder_destroy(). |
| 291 | |
| 292 | The raw decoder now supports Teletext system A, C and D and pseudo-VPS |
| 293 | on the second field. Blank line detection has been disabled. As a result |
| 294 | the decoder will run a bit slower but Robin Imrie pointed out that |
| 295 | caption / subtitles may be lost if the signal inserter is disabled |
| 296 | during longer periods of silence. |
| 297 | |
| 298 | The DVB demultiplexer added in 0.2.9 is now public. |
| 299 | |
| 300 | Other fixes: |
| 301 | - In 0.2.9 the I/O routines may crash if passed a NULL errorstr pointer. |
| 302 | - Replaced uname call in configure.in by AC_CANONICAL_HOST. |
| 303 | - Missing documentation. |
| 304 | |
| 305 | 0.2.9 |
| 306 | ----- |
| 307 | This version contains the VBI proxy code by Tom Zoerner. With the proxy |
| 308 | multiple applications can share a V4L or V4L2 VBI device. For details see |
| 309 | daemon/README. |
| 310 | |
| 311 | Distro packagers please consider adding the proxy daemon to the system |
| 312 | init sequence. |
| 313 | |
| 314 | Other changes: |
| 315 | - Libzvbi now installs a zvbi-0.2.pc (pkg-config) file. |
| 316 | - Added ioctl logging to V4L and V4L2 interface for tests. |
| 317 | - Extended capture and osc apps for easier i/o testing. |
| 318 | - Added experimental DVB mux & demux. Not yet supported by the |
| 319 | DVB driver interface due to lack of testing but test/capture |
| 320 | and test/export use it. |
| 321 | |
| 322 | Fixes: |
| 323 | - Teletext decoder: switching between primary and secondary character |
| 324 | set did not work right. |
| 325 | |
| 326 | 0.2.8 |
| 327 | ----- |
| 328 | Updated the network identification table from TR 101 231 EBU (2004-04a). |
| 329 | Incorporated corrections by Stephane Loeuillet (bug #942434). |
| 330 | |
| 331 | 0.2.7 |
| 332 | ----- |
| 333 | Fixes a bug in the v4l2 interface, didn't work with bttv driver 0.9.12. |
| 334 | |
| 335 | 0.2.6 |
| 336 | ----- |
| 337 | Libzvbi goes digital! Gerd Knorr contributed a Linux DVB interface. |
| 338 | It's not really finished yet but seems usable. You can try this: |
| 339 | test/capture --device /dev/dvb/adapter<n>/demux<n> --pid 123 --dump-ttx |
| 340 | Further James Mastros improved test/osc and a segv bug was fixed |
| 341 | in the page formatting code. |
| 342 | |
| 343 | 0.2.5 |
| 344 | ----- |
| 345 | New this time is a vbi_version() function to query the version |
| 346 | of the library at runtime. If your application uses autoconf to |
| 347 | configure you can test for its presence with the AC_CHECK_LIB |
| 348 | macro. The remaining changes are bug fixes, read about the |
| 349 | details in ChangeLog. |
| 350 | |
| 351 | 0.2.4 |
| 352 | ----- |
| 353 | V4L2 (Linux 2.5+) devices were not correctly identified because |
| 354 | the API changed since the interface was first added in version |
| 355 | 0.2.3. This version contains an updated header file. |
| 356 | |
| 357 | 0.2.3 |
| 358 | ----- |
| 359 | Bug fixes, mostly compile problems. This version supports the |
| 360 | refurbished V4L2 API for Linux 2.5ff and has been ported to |
| 361 | FreeBSD 4.6, including a bktr driver interface. Basic tests ok, |
| 362 | remains to be seen how well this works in the field. |
| 363 | |
| 364 | 0.2.2 |
| 365 | ----- |
| 366 | RH 7.3 build fix (zapping-Bugs-568052) and switch to gettext 0.11. |
| 367 | Libzvbi can now build in a separate dir. Several other bug fixes, |
| 368 | most notably localization works now. |
| 369 | |
| 370 | 0.2.1 |
| 371 | ----- |
| 372 | Bug fixes. |
| 373 | |
| 374 | 0.2 |
| 375 | --- |
| 376 | Bug fixes, most notably the character code range check in the |
| 377 | Closed Caption decoder, a V4L2 interface update to work with bttv |
| 378 | 0.8.x, and new handler registration functions (the old ones were |
| 379 | retained for compatibility). |
| 380 | |
| 381 | 0.1.1 |
| 382 | ----- |
| 383 | Bug fixes. |
| 384 | |
| 385 | 0.1 |
| 386 | --- |
