Setting the filter input parameters is moved to init_input_stream(),
so that it is done before the decoder is opened, potentially overwriting
the information from avformat_find_stream_info() with less accurate
data.
This commit temporarily disables QSV transcoding with hw frames. The
functionality will be re-added in the following commits.
Currently, calling configure_filtergraph() will pull in the input
parameters from the corresponding decoder context. This has the
following disadvantages:
- the decoded frame is a more proper source for this information
- a filter accessing decoder data breaks proper layering
Add functions for explicitly sending the input stream parameters to a
filtergraph input - currently from a frame and a decoder. The decoder
one will be dropped in future commits after some more restructuring.
The encode function is supposed to just return 0 on success.
This stems from a mixup with the return value of decode functions.

No longer make a dummy device configuration to query. Instead, just
return everything we recognise from the whole format list. Also
change the device setup code to query that list only, rather than
intersecting it with the constraint output.
This makes hwupload more usable on mesa/gallium where the video
processor only declares support for RGB formats, making it unable to
deal with YUV formats before this patch. It might introduce some
different trickier failures in the internal upload/download code
because the set of allowed formats there has changed, though I didn't
find any obvious regressions with i965.
The functions may not clean up properly after using MMX
registers. For the normal testing calls, the checkasm_checked_call
functions will do the cleanup (and check that functions that
should clean up do it as well), but when benchmarking functions
that don't clean up, we don't currently properly clean up at all.
This causes issues if a benchmarked function is followed by testing
of a function that is supposed to not clobber the MMX/FPU state but
doesn't touch it at all.

Currently it's exported as AVFrame.pkt_pts, which is also the only use
for that field. The reason it is done like this is that lavc used to
export various codec-specific "timing" information in AVFrame.pts, which
is not done anymore.
Since it is confusing to the callers to have a separate field which is
used only for decoder timestamps and nothing else, deprecate pkt_pts and
use just AVFrame.pts everywhere.
The current code assumes that encoding_needed is simply an inverse of
stream_copy, which is not true for manually attached files (for which
neither of those is true).
We already have all the necessary information in open_output_file().
This makes the information about the stream/filtergraph mappings
available earlier.
This is a more appropriate place for this. H264Context.recovery_frame is
shared between frame threads, so modifying it where it is right now is
invalid.
Move the NAL unit types into it. This will allow to stop including the
whole decoder-specific h264dec.h in some code that is unrelated to the
decoder and only needs some enum values.
