It allows to configure how long will avformat_find_stream_info() wait
to get the first timestamp.

alsa and x11grab use av_gettime() to report timestamps.

This option facilitates testing shared libarary builds: for instance
fate builders do no longer need to set LD_LIBRARY_PATH as the binaries will
get the right search paths hardcoded into their executable file.

This option is only meant to be used for testing purposes: The installed
libraries must not move around in the file system, and doing so will
cause a lot of subtle problems. For more information why using RPATH is
dangerous, please refer to

This avoids a number of redefinition warnings on MinGW64.

Since they are aliases for ogg enabling any of them enables ogg as well.

It is hardcoded to 15fps.

At least one FATE sample contains such chunks and happens to work simply
by accident (due to find_stream_info() swallowing the error).

MpegEncContext based decoders are only fully initialized after the first
ff_thread_get_buffer() call. The RV30/40 decoders may fail before a frame
buffer was requested. ff_mpeg_update_thread_context() fails on half
initialized MpegEncContexts. Since this can only happen before a the
first frame was decoded there is no need to call
ff_mpeg_update_thread_context().

Based on patches by John Stebbins and tested by John Stebbins.

The same is done for GCC and clang already.

Also convert a debug av_log() to av_dlog().

The asserts check struct members that are not referenced in guess_mv()
and one of them fails to compile.

This avoids an unused variable warning with MSVC since the variable is
only used in a debug mode printf statement.

The defines were added long ago when MinGW still lacked them.

This is cleaner and avoids an uninitialized variable warning with MSVC.

The packet buffer allocation considers the alpha channel as DCT-coded,
while it is actually run-coded and thus requires a larger buffer.

The buffer allocation may be incorrect (e.g. with an alpha plane),
and currently causes the buffer to be set to NULL by init_put_bits,
causing a crash later on.

So, detect that situation, and if detected, reallocate the buffer
and ask for a sample that shows the problem.

If the allocated size, despite best efforts, is too small, exit

Update mxf_set_audio_pts to use the container-provided information.

The UL is marked as "to be changed in the future", but the current
