libzvbi 0.2.35, 2013-08-28 -------------------------- Some corrections to allow compilation with clang/LLVM and uClibc, and a bug fix in test/time.c. libzvbi 0.2.34, 2013-07-11 -------------------------- This is a surprise bugfix release with improvements in the Teletext decoder and zvbi-atsc-cc. libzvbi 0.2.33, 2008-09-03 -------------------------- Fixes two zvbi-atsc-cc compile problems. libzvbi 0.2.32, 2008-08-20 -------------------------- This version adds a new tool named zvbi-atsc-cc to record Closed Caption from ATSC digital TV. It supports legacy NTSC caption (EIA 608-B) and DTVCC (CEA 708-C). libzvbi 0.2.31, 2008-07-26 -------------------------- The vbi_caption_unicode() function did not correctly translate the small letter i with diaresis. The files daemon/chains.c, daemon/proxyd.c, test/proxy-test.c and test/cc-test-stream.dtd are now licensed under GPLv2 or later as stated in the top README file. libzvbi 0.2.30, 2008-03-05 -------------------------- This is a bugfix release restoring the functions vbi_unref_page(), vbi_is_cached() and vbi_cache_hi_subno() which were accidentally dropped in libzvbi 0.2.28. libzvbi 0.2.29, 2008-02-24 -------------------------- This version fixes incompatibilities with strict ISO C in the libzvbi header file. libzvbi 0.2.28, 2008-02-22 -------------------------- The ZVBI libraries libzvbi and libzvbi-chains are now licensed under the terms of the GNU Library General Public License version 2 or later. Example programs are now licensed under a 2-clause BSD-style license. The VBI proxy daemon, contributed programs, test programs and programs required to build the library remain licensed under GNU General Public License version 2 or later. Bug fixes: - A Teletext Level 2.5 transparency attribute bug was fixed in the teletext decoder. - The capture test tool did not work with DVB devices. Other changes: - The VTX export module has been disabled for licensing reasons. It may return after a rewrite. - New BCD functions and vbi_ham24p(), counterpart of vbi_unham24p(), were added. - The artificial 41st column in Teletext pages is no longer black but continues the previous column if appropriate. - The --default-cs option of the export test tool now works with libzvbi 0.2 as well. libzvbi 0.2.27, 2008-02-14 -------------------------- This is a bugfix release. - The DVB VBI demultiplexer entered an endless loop on some input. - The Closed Caption special character conversion did not work. libzvbi 0.2.26, 2007-11-27 -------------------------- - The experimental DVB VBI multiplexer was improved and support for raw VBI data was added. It is now part of the API. - The bit slicer was improved to give better results with noisy Closed Caption signals and the capture device simulator can now simulate noisy signals. Thanks go to Rich Kadel for testing. - Tom Zoerner contributed an XPM export module and added support for an 8-bit indexed format to the Teletext page rendering functions. The PNG and PPM modules work a little more efficiently now. Two functions were added to export Teletext and Closed Caption pages into memory instead of an i/o stream or file. Bug fixes: - The V4L2 capture interface did not properly initialize the parameters for VIDIOC_QBUF and VIDIOC_DQBUF ioctl calls. It also failed to resume capturing after the bttv driver returned an EIO error. - The DVB capture interface did not work with all drivers because the device file was opened for reading and writing. - The vbi_sliced_name() and vbi_sliced_payload_bits() functions returned nothing for VBI_SLICED_TELETEXT_B_L25_625. - The Teletext decoder permitted double width characters in the last column. - In the vbi_pfc_demux_cb function prototype the second and third parameter were swapped. Fix by Tom Zoerner. - The vbi_decoder_delete function did not free the event handler list. - The text and HTML export modules did not free some internal data on errors. The test tools were improved: - All tools now support a --verbose option for debugging, and --quiet, --help, --usage and --version options. - The capture tool can now generate DVB VBI PES and TS streams with variable packet size to reduce the number of stuffing bytes, and user defined TS PID. An -o output file option was added. New device simulation options were added and raw VBI capturing is now possible. Capturing through the VBI proxy was added by Tom Zoerner. The timestamps in the output were incorrect if a frame contained no data, this was fixed. - The decode tool now accepts DVB VBI PES and TS streams and an -i input file option was added. IDL-A decoding works again. - The export tool now accepts DVB VBI PES and TS streams and an -i input file option was added. It can now export multiple pages, has a new -o output file option, and can list the possible file formats and conversion options. - The sliced2pes tool now also accepts DVB VBI PES and TS streams, has a new -i input and -o output file option, and can produce DVB VBI PES and TS streams with user defined packet size, data_identifier and TS PID. - The ttxfilter tool accepts DVB VBI PES and TS streams, has a new -i input and -o output file option. A time option was added to cut Teletext (esp. subtitle) streams. Various bugs were fixed. - Courtesy of Tom the osc tool can now capture raw data through the VBI proxy. - Raw VBI capturing with the proxy-test tool works again, also fixed by Tom. Build fixes: - The package did not compile with ./configure --disable-static (bug #1692015). libzvbi 0.2.25, 2007-03-09 -------------------------- This version fixes a buffer overflow bug in the zvbi-ntsc-cc tool which may cause a segfault on reception errors. Secondly it fixes a GNU/kFreeBSD compile problem (Debian bug #407621). libzvbi 0.2.24, 2006-11-29 -------------------------- This version fixes a bug in the zvbi-ntsc-cc tool which may cause a segfault on reception errors. libzvbi 0.2.23, 2006-10-27 -------------------------- This versions adds a few helper functions to convert Closed Caption and UCS-2 strings. The raw VBI decoder was modified to handle a CC signal with incorrect clock run-in. The zvbi-ntsc-cc tool can now decode all caption channels simultaneously and convert from caption to locale character encoding for proper display of Spanish captions. It can write caption and XDS information to separate files. Some bugs in the XDS decoder were fixed and a filter was added to discard unwanted XDS information and WebTV links. Fixes: - The library did not compile on GNU/kFreeBSD due to a name space conflict with the RAW macro (Debian bug #372302). libzvbi 0.2.22, 2006-05-30 -------------------------- This version adds a simulated raw and sliced VBI capture device to debug applications. The VBI simulation in the capture and osc tools is more accurate and VPS signals can be simulated. Functions to convert sliced VBI data to raw VBI images are public now and an example application was added. An interface to enable warning and debugging messages was added. Fixes: - Bit slicing of WSS data started a little early. It should work better now with noisy signals. - The WSS capture example used an incorrect bytes-per-line value. - A work-around for a line allocation bug in older versions of the bttv driver was added. Enables capturing of single lines (VPS, WSS, CC). libzvbi 0.2.21, 2006-05-10 -------------------------- This is a bugfix release. - Capturing WSS data from video images failed due to a broken check in the raw VBI decoder. libzvbi 0.2.20, 2006-05-08 -------------------------- This version supports raw VBI capturing with unknown field order, adds a work-around for a VBI offset bug in the bttv driver, enables additional debugging messages and improves some test tools. Network identification now returns CNIs and a network identification example was added. The CNI (networks) table was updated. libzvbi 0.2.19, 2006-02-23 -------------------------- This is a bugfix release. - Due to a preprocessor mishap zvbi-ntsc-cc did not use libzvbi but its own VBI decoder. libzvbi 0.2.18, 2006-02-11 -------------------------- This is a bugfix release. - The configure script has been modernized. Building from CVS now requires automake 1.9, autoconf 2.59 and gettext 0.14. - Diego Pettenò added a configure option to disable documentation building regardless if doxygen is installed. - After make clean src/Makefile tried to rebuild network-table.h from http://zapping.sourceforge.net/zvbi-0.3/networks.xml and other source files. This make rule was only intended for the maintainer. - A pointer aliasing bug in the linked list implementation of the Teletext cache, which may crash applications, has been fixed. - In previous versions GCC may not have inlined some bit slicer and page rendering functions, making them much slower. - The teletext filter added in 0.2.17 did not work with parallel page transmission (e.g. BBC). - The code was cleaned up to muffle compiler warnings (Diego). libzvbi 0.2.17, 2005-10-07 -------------------------- This version adds missing XDS packet subclasses to the XDS demultiplexer. The contrib directory now contains a version of the ntsc-cc Closed Caption decoder from the Xawtv package using libzvbi for driver access and bit slicing. It installs as zvbi-ntsc-cc. The CNI (networks) table was updated. The test tools were cleaned up and a teletext filter was added. Fixes: - The DVB multiplexer didn't work right (used by test tools only, not part of the API yet). - The ioctl logger (test stuff) didn't log VIDIOC_G_STD and VIDIOC_S_STD. - test/decode option -a didn't work. libzvbi 0.2.16, 2005-05-25 -------------------------- This version adds a new demultiplexer to extract XDS data from a caption stream (EIA 608). Fixes: - test/caption, test/osc did not compile due to a bug in the configure script. - Removed a misplaced assertion in vbi_capture_io_update_timeout(). - test/osc, test/capture, test/wss -d option segfaulted. - Fixed NTSC VBI capturing in the Linux saa7134 0.2.13 driver and added a partial work-around here for older versions. - The HTML export module segfaulted. Fix by Bernhard Rosenkraenzer. libzvbi 0.2.15, 2005-03-28 -------------------------- This is a bugfix release. Due to an incorrect bytes per line check previous versions could not capture VBI data from the ivtv driver. libzvbi 0.2.14, 2005-02-28 -------------------------- This version adds new demultiplexers to extract data transmissions from Teletext streams, namely in "Page Format Clear" format (e.g. NexTView EPG) and "Independent Data Line Format A". A new low-level decoding tool was added for tests. libzvbi 0.2.13, 2005-01-23 -------------------------- This version has new, more reliable DVB VBI capture routines. See the documentation of vbi_capture_dvb_new() for details. Fixes: - vbi_capture_bktr_new() ignored the scanning parameter, always assuming 625 line systems (e.g. PAL-BGHI, SECAM-L). - Include fix in test/wss.c. - vbi_unham8() return type signedness fix. - GCC 4.0 compile fixes. libzvbi 0.2.12, 2005-01-18 -------------------------- Various error correction functions, generator and bit reversal functions useful for VBI decoding are public now. A new test app has been added to capture WSS data from video images. French translation update by Christian Marillat. Bttv drivers 0.9.0 - 0.9.15 report wrong PAL/SECAM field 2 line numbers. A work-around has been added, and a bug compatible Teletext data service table entry has been corrected. If you encounter problems using similarly broken drivers please try a fuzzy match of driver capabilities and data service parameters (e.g. vbi_capture_v4l2_new(strict <= 1)) and notify mschimek@users.sf.net. The test/capture and test/osc apps did not capture PAL/SECAM line 23 (WSS), this has been fixed. libzvbi 0.2.11, 2004-12-31 -------------------------- Build fix. Cough. libzvbi 0.2.10, 2004-12-30 -------------------------- The bit slicer and raw VBI decoder have been replaced by improved and better tested versions. Developers please note: memory will leak if you do not call vbi_raw_decoder_destroy(). The raw decoder now supports Teletext system A, C and D and pseudo-VPS on the second field. Blank line detection has been disabled. As a result the decoder will run a bit slower but Robin Imrie pointed out that caption / subtitles may be lost if the signal inserter is disabled during longer periods of silence. The DVB demultiplexer added in 0.2.9 is now public. Other fixes: - In 0.2.9 the I/O routines may crash if passed a NULL errorstr pointer. - Replaced uname call in configure.in by AC_CANONICAL_HOST. - Missing documentation. 0.2.9 ----- This version contains the VBI proxy code by Tom Zoerner. With the proxy multiple applications can share a V4L or V4L2 VBI device. For details see daemon/README. Distro packagers please consider adding the proxy daemon to the system init sequence. Other changes: - Libzvbi now installs a zvbi-0.2.pc (pkg-config) file. - Added ioctl logging to V4L and V4L2 interface for tests. - Extended capture and osc apps for easier i/o testing. - Added experimental DVB mux & demux. Not yet supported by the DVB driver interface due to lack of testing but test/capture and test/export use it. Fixes: - Teletext decoder: switching between primary and secondary character set did not work right. 0.2.8 ----- Updated the network identification table from TR 101 231 EBU (2004-04a). Incorporated corrections by Stephane Loeuillet (bug #942434). 0.2.7 ----- Fixes a bug in the v4l2 interface, didn't work with bttv driver 0.9.12. 0.2.6 ----- Libzvbi goes digital! Gerd Knorr contributed a Linux DVB interface. It's not really finished yet but seems usable. You can try this: test/capture --device /dev/dvb/adapter/demux --pid 123 --dump-ttx Further James Mastros improved test/osc and a segv bug was fixed in the page formatting code. 0.2.5 ----- New this time is a vbi_version() function to query the version of the library at runtime. If your application uses autoconf to configure you can test for its presence with the AC_CHECK_LIB macro. The remaining changes are bug fixes, read about the details in ChangeLog. 0.2.4 ----- V4L2 (Linux 2.5+) devices were not correctly identified because the API changed since the interface was first added in version 0.2.3. This version contains an updated header file. 0.2.3 ----- Bug fixes, mostly compile problems. This version supports the refurbished V4L2 API for Linux 2.5ff and has been ported to FreeBSD 4.6, including a bktr driver interface. Basic tests ok, remains to be seen how well this works in the field. 0.2.2 ----- RH 7.3 build fix (zapping-Bugs-568052) and switch to gettext 0.11. Libzvbi can now build in a separate dir. Several other bug fixes, most notably localization works now. 0.2.1 ----- Bug fixes. 0.2 --- Bug fixes, most notably the character code range check in the Closed Caption decoder, a V4L2 interface update to work with bttv 0.8.x, and new handler registration functions (the old ones were retained for compatibility). 0.1.1 ----- Bug fixes. 0.1 --- Former module of the Zapping TV viewer, this is the first release of the Zapping/Zapzilla VBI decoder as a standalone library.
