Also remove pthread_cond_broadcast(progress_cond) on uninit.
Broadcasting it is not required because workers are always
parked when they are not in thread_execute. So it is imposible
that a worker is waiting on progress_cond when uninitialized.

Rework it to improve performance. Now mutex is not shared by workers,
instead each worker has its own mutex and condition variable. This
reduces lock contention between workers. Also use atomic variable for
counter.
The interface also allows execute to run special function on main
thread, requested by Ronald.

Muxers may want to directly access filename in stored in
AVFormatContext. For example in case of RTSP, the filename (url)
is used by the muxer to extract parameters of the connection.
These muxers will fail when used with fifo pseudo-muxer.
This commit fixes this issue by passing filename from AVFormatContext
of fifo pseudo-muxer to all AVFormatContext(s) of underlying muxers
during initialization.

Avoid using bitstream reader in a non-standard way by directly accessing

Permits applications to access DTS profile information without having to
decode a frame.
Signed-off-by: James Almer <jamrial@gmail.com>
|
|
This makes probing for regular DTS more strict because more header
fields are checked and values not supported by decoder are now rejected.
Also fixes an issue original code had with 14-bit streams: 96 bits of
header were expected, however only 84 bits were converted, which was not
enough to parse LFE flag.

There are 3 different places where DCA core frame header is parsed:
decoder, parser and demuxer. Each one uses ad-hoc code. Add common core
frame header parsing function that will be used in all places.

It will be used by the parser. This change avoids unwanted parser
dependency on dcadata.

These values will be used by the parser. Prefix them with DCA_

Hardware pixel formats do not tell you anything about their actual
contents, but should still score higher than formats with completely
unknown properties, which in turn should score higher than invalid
formats.
Do not return an AVERROR code as a score.
Fixes a hang in libavfilter where format negotiation gets stuck in a
loop because AV_PIX_FMT_NONE scores more highly than all other
possibilities.
