When we have an input width/height that should be used for clipping, only
perform the clipping if the rectangle is smaller than the actual picture size.
Fixes#330681
Don't escape the codec_data, it breaks some streams (but likely also fixes
others). It's better to leave it as is, like most other players do.
See #608332
Make check for vdpau decoders more generic. There might be vdpau
decoders we don't expect when using an external ffmpeg version,
and we want those blacklisted as well (e.g. ffdec_mpeg4_vdpau).
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.
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.
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.
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.
...instead of just doing nothing when setting it. This makes sure
that people notice that they shouldn't set the property because
it creates a warning now.
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.
Fixes bug #593651.

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.
ffmpeg typefinders don't do bounds checking for small chunks of
data, so just skip them if we don't have a lot of data, to avoid
invalid memory access and/or crashes.
