configure.ac: Fix configure check for mpeg2enc. We need 1.6.1.93 instead of 1.6.1.92, since the pkg-config file of 1.... Original commit message from CVS: 2004-01-01 Ronald Bultje <rbultje@ronald.bitfreak.net> * configure.ac: Fix configure check for mpeg2enc. We need 1.6.1.93 instead of 1.6.1.92, since the pkg-config file of 1.6.1.92 is borked and it therefore uses the wrong include paths. Too bad... Note that 1.6.1.93 is not release yet. ;). Also add a check for mplex, which is now using the lib'ified mplex from mjpegtools, too. * ext/ffmpeg/gstffmpegcodecmap.c: Add codec_tag for 3ivx/xvid. For xvid, this should fix playback issues. I don't think ffmpeg handles 3ivx correctly, so this probably won't work. But it won't hurt either. * ext/ffmpeg/gstffmpegdec.c: (gst_ffmpegdec_connect), (gst_ffmpegdec_chain): * ext/ffmpeg/gstffmpegenc.c: (gst_ffmpegenc_connect), (gst_ffmpegenc_chain_audio): Fix memleak in audio encoding. Close codec if open fails, this calls the cleanup routines so we can re-use the context. * ext/mpeg2enc/gstmpeg2enc.cc: Fix pad template names/types, fix memory issue with getcaps(). * ext/mpeg2enc/gstmpeg2encoder.cc: * ext/mpeg2enc/gstmpeg2encoder.hh: Fix compile issue with new caps system (const thingy). * ext/mpeg2enc/gstmpeg2encpicturereader.cc: * ext/mpeg2enc/gstmpeg2encpicturereader.hh: We read a first frame right on initing, so that we have a caps when we init the output. This caps is cached in padprivate and read as first frame. * ext/mplex/Makefile.am: * ext/mplex/gstmplex.cc: * ext/mplex/gstmplex.h: * ext/mplex/gstmplex.hh: * ext/mplex/gstmplexibitstream.cc: * ext/mplex/gstmplexibitstream.hh: * ext/mplex/gstmplexjob.cc: * ext/mplex/gstmplexjob.hh: * ext/mplex/gstmplexoutputstream.cc: * ext/mplex/gstmplexoutputstream.hh: We wrap mjpegtools mplex. So I rewrote the plugin. The old plugin had issues, didn't do capsnego, supported only a subset of the mplex features and required a mplex fork in our local CVS. Plus that it worked agaist a very old mplex version.

This makes some parts of AVI playback/reading work. * sys/ximage/ximagesink.c: (gst_ximagesink_sinkconnect): Resize window on new capsnego. This is probably wrong, but I'm still committing it because with current capsnego, the first successfull capsnego is auto-fixated, therefore rounded down to the lowest values in the caps. this results in a 16x16 XWindow that is not reized when real capsnego finishes. Dave, I see more cases of this, do you know a proper solution? * tools/gst-launch-ext.in: Fix MPEG-4 AAC (Apple iPod/iTunes) file commandline.

So I rewrote the plugin. The old plugin had issues, didn't do capsnego, supported only a subset of the mplex features and required a mplex fork in our local CVS. Plus that it worked agaist a very old mplex version. Rewriting was faster than updating it. * gst-libs/ext/Makefile.am: * gst-libs/ext/mplex/INSTRUCT: * gst-libs/ext/mplex/Makefile.am: * gst-libs/ext/mplex/README: * gst-libs/ext/mplex/TODO: * gst-libs/ext/mplex/ac3strm_in.cc: * gst-libs/ext/mplex/audiostrm.hh: * gst-libs/ext/mplex/audiostrm_out.cc: * gst-libs/ext/mplex/aunit.hh: * gst-libs/ext/mplex/bits.cc: * gst-libs/ext/mplex/bits.hh: * gst-libs/ext/mplex/buffer.cc: * gst-libs/ext/mplex/buffer.hh: * gst-libs/ext/mplex/fastintfns.h: * gst-libs/ext/mplex/format_codes.h: * gst-libs/ext/mplex/inputstrm.cc: * gst-libs/ext/mplex/inputstrm.hh: * gst-libs/ext/mplex/lpcmstrm_in.cc: * gst-libs/ext/mplex/mjpeg_logging.cc: * gst-libs/ext/mplex/mjpeg_logging.h: * gst-libs/ext/mplex/mjpeg_types.h: * gst-libs/ext/mplex/mpastrm_in.cc: * gst-libs/ext/mplex/mpegconsts.cc: * gst-libs/ext/mplex/mpegconsts.h: * gst-libs/ext/mplex/mplexconsts.hh: * gst-libs/ext/mplex/multplex.cc: * gst-libs/ext/mplex/outputstream.hh: * gst-libs/ext/mplex/padstrm.cc: * gst-libs/ext/mplex/padstrm.hh: * gst-libs/ext/mplex/stillsstream.cc: * gst-libs/ext/mplex/stillsstream.hh: * gst-libs/ext/mplex/systems.cc: * gst-libs/ext/mplex/systems.hh: * gst-libs/ext/mplex/vector.cc: * gst-libs/ext/mplex/vector.hh: * gst-libs/ext/mplex/videostrm.hh: * gst-libs/ext/mplex/videostrm_in.cc: * gst-libs/ext/mplex/videostrm_out.cc: * gst-libs/ext/mplex/yuv4mpeg.cc: * gst-libs/ext/mplex/yuv4mpeg.h: * gst-libs/ext/mplex/yuv4mpeg_intern.h: * gst-libs/ext/mplex/yuv4mpeg_ratio.cc: We don't fork mjpegtools' mplex in our CVS anymore. * gst/avi/gstavidemux.c: (gst_avi_demux_src_getcaps), (gst_avi_demux_add_stream): * gst/avi/gstavidemux.h: Add getcaps() function for proper caps nego. This makes some parts of AVI playback/reading work. * sys/ximage/ximagesink.c: (gst_ximagesink_sinkconnect): Resize window on new capsnego. This is probably wrong, but I'm still committing it because with current capsnego, the first successfull capsnego is auto-fixated, therefore rounded down to the lowest values in the caps. this results in a 16x16 XWindow that is not reized when real capsnego finishes. Dave, I see more cases of this, do you know a proper solution? * tools/gst-launch-ext.in: Fix MPEG-4 AAC (Apple iPod/iTunes) file commandline.
