Original commit message from CVS:
Several encoding changes:
* for video, double check the pix_fmt after opening the AVCodec. The pix_fmt
will be changed to the preferred pix_fmt instead of that opening the
codec fails. We fail when it has changed (then, ffmpeg doesn't like it).
* for video, set the correct timestamp.
* for audio, do *not* set the frame_size: most codecs don't like it. Instead,
keep a cache of buffers and always give data of size "frame_size". Maybe
I should have used bytestream here, I'm not sure. This works, though.
I can now create mpeg1 video, mp2 and ac3 audio. I didn't test any others yet.
I also didn't start working on integration with any of the muxers yet, that's
all one big TODO. One thing at a time, please. :).
Original commit message from CVS:
some fixes:
- put back a fix to make generic audio caps fixed.
- read out all of the flags when constructing wma extradata
Original commit message from CVS:
fix GST_FF_AUD_CAPS_NEW to not include channels and rate in unfixed caps and make audio caps use them again. This ensures that audio encoders set these properties when setting fixed caps and audio decoders can advertise fixed caps, too. This should work in all cases. If not, change it back and ffdec_mp3 is broken again ;)
Original commit message from CVS:
Re-enable realaudio codecs, improve decoder naming and add mpeg2aac decoder... Now to find out why it still doesn't list itself after gst-register'ing...
Original commit message from CVS:
Make it compile against latest CVS of FFMPEG:
* Put gst/gst.h above avcodec.h because it needs some types defined in glib.h
* Remove HQ (removed from lavc) property
Also add some functions to make SVQ1 decoding work:
* Add YUV9 colorspace
* Let lavc do its own buffer allocation and copy from there instead of using
our own buffer allocation functions. Somehow, that breaks. I don't know
why.
Original commit message from CVS:
New mimetypes gone into effect today - this commit changes all old mimetypes over to the new mimetypes spec as described in the previous commit's document. Note: some plugins will break, some pipelines will break, expect HEAD to be broken or at least not 100% working for a few days, but don't forget to report bugs
Original commit message from CVS:
We also need raw video/audio caps for the demuxer/muxer, plus that caps_to_codecid() didn't exist (thanks for noticing, dave)
Original commit message from CVS:
MPEG4AAC is MPEG-4 audio, not video, and implement a _formatid_to_caps() function which tracks a GstCaps to a format name (muxing format etc.), useful for setting caps on demuxers
Original commit message from CVS:
* remove gstffmpegdecall. This was a temporary hack to get around
some issues with our video/avi-centered mimetype system. Now that
we use proper identifiers, we don't need that piece of cruft anymore.
* update ffmpeg codec map for ffdec_*, plus make the uncompressed stream
caps also be formed by the codec mapper (this is easier to handle imo).
* add audio support (untested, though :P).
* remove the copying of buffer content and add a get_buffer() handler
instead.
* add an int to ffmpegenc to make it compile and resolve the symbol. I'll
truely fix that later on.
* make mimetypes in the ffmpeg codec mapper conform to docs/random/mimetypes
* etc.
Oh, and let's not forget that it can play back DIVX5 et all nicely. Support
for SVQ1/3 is also there, so if someone completes qtdemux, we can watch
these, too.
Original commit message from CVS:
Release early.. try to wrap more ffmpeg stuff, like muxers and demuxers.
This thing needs a fix in ffmpeg (which I will send to the ffmpeg authors
eventually)
