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/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. Rewriting was
faster than updating it.

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.
