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.

Add GPLv2 COPYING file, and LGPL COPYING.LIB. Add the boilerplate
text about the plugin code being LGPL versus the linked plugin
being GPL.
Fixes: #590964
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.
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.
Fixes bug #578278.
This cleans up licensing and makes it possible to build with LGPL code
only again.
Apart from that an opencore-amr encoder/decoder exists now but this
is not enabled as we don't want to use external libraries through ffmpeg
and have our own plugins for this already.
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).
Fixes#575545
Takes codec frame delay into account (roughly the same way it does for timestamps for reordered frames) to produce frames with correct offsets.
A special hack to allow trailing frame with timestamp=segment.stop to be displayed.
Fixes bug #578278.
