faa417cf34 caps: Use default audio channel layouts for some codecs
For a few white-listed codecs, use default fallback channel
layouts when ffmpeg doesn't inform us.

Make the keyframe forcing thread-safe, also emit a downstream event
to allow muxers or payloaders to react appropriately.

62d54db07d ffmpeg: VC-1/WMV3 fixes.
Use format field in the pad caps to differentiate VC-1 from WMV3.
Fix a typo in the caps creation and parsing - the field is called
'format' - not 'fourcc'

Add a dodgy hack to populate the extradata size field
(first byte) when it is 0 - as it seems to be for some (Matroska)
test files.

19e81024a3 Always give the most video restricted caps possible
When the video caps aren't fixed yet, make sure we return the most
precise set of caps. It seems a regression was introduced in cc082f,
causing restricted caps to never be used if the context == NULL

None of the restricted caps generation uses the context, so no need to
check whether the context.

Fixes bug #578160.

a1384f990b ffmpegdec: Only restore default in AVCodecContext when needed.
Resetting default values is currently very complex in libavcodec, so
we only call it when needed (i.e. when a context was previously used).

Shaves off 10% of the setup of a decoder.

087582d7cd Revert "ffenc: Make the buffer-size property read-only"
This reverts commit 98439aacc7.

Instead of printing a warning when trying to set the property
it should do nothing as before and the property description
should contain a note that setting it has no effect.

c914f08b40 ffenc: Make sure to always provide large enough buffers
For audio always add the minimum ffmpeg buffer size, for video
use the same weird buffer size as they use in ffmpeg.c:
width*height*6 + 200

Also make setting of the buffer-size property a no-op.

46bf3b92d0 ffdec: disable interpolation when dropping frames
When we are dropping frames because of QoS disable the DTS interpolation because
we won't be able to update the timestamps and end up setting the wrong
timestamps. Instead, simply use the timestamps from ffmpeg.

invalid memory access and/or crashes.

54428c186b ffmpegdec: Assign offsets to outgoing buffers more accurate
This now uses ffmpeg functionality to keep random metadata next to
the buffers and to get the correct offset for a frame, similar to how
timestamps are handled.

56887682d0 gstffmpegenc: Try getting the caps for the declared pixfmt without a context.
PixFmt that are declared in AVCodec.pix_fmts are ones which are 'officially'
declared as being supported. We should therefore not have to create a
AVCodecContext and open an encoder to know if it's supported or not.
Also, doing it this way allows us to better pickup configuration overrides
we have in gstffmpegcodecmap for some codecs (like restrictions on width,
height, framerate like it's the case for dnxhd).

d917f59a84 ffmpegdemux: cache events from upstream and re-send them later
Cache any events we get from upstream before we're open, especially
tag events we may be getting from apedemux/id3demux or the like, and
push them downstream later when we've added our pads instead of just
dropping them silently. Fixes transcoding tags for Monkey's Audio
Files with preceding APE or ID3v2 tags (#586957). Add minimal unit
test for this.

Also push stream tags later after the global tags and the newsegment
event rather than right after creating the pad.

fe10ecd097 ffdec: don't wait for keyframe after discont
After a DISCONT, mark the next frame with DISCONT but don't wait for a new
keyframe. This greatly improves performance on lossy networks or currupted
frames as the decoder can usually continue and conceil errors up to the next
keyframe.
