It is av_opt_set now.

Add SPS_EXT, SEI, and subset SPS to codes that are skipped during split.
These codes can come before the PPS and results in incomplete extradata.

Use av_mallocz_array instead of iterating and check the returned memory.
Check returned memory and cleanly exit in case of error during the loop.
Avoid a null pointer dereference for invalid data.

vorbis_parser.o is built unconditionally since 5e80fb7f, and the
unconditionally built parts of it depend on xiph.o.

This fixes builds with --disable-everything.

The latest fdk-aac code drop (from android 5.0) changed the channel
layout enums (changing the value of existing enum constants), and
renamed the option for downmixing.

The failsafe comparison between ctype and FF_ARRAY_ELEMS(channel_counts)
can trigger warnings (-Wtautological-constant-out-of-range-compare)
when building with the old FDK AAC releases, where it can't be
out of range with the enum values used there.

This avoids a potential crash if writing a fragmented psp mp4
(which probably is only a hypothetical scenario).

Previously we wrote decoding timestamps here, while the specs
say it should be presentation timestamps.

When using the new first_trun flag instead of checking the track id,
we don't need to have a special case for the separate_moof flag
any longer.

This simplifies the complicated codepath ever so slightly.

In this case, shift tracks to start from zero instead (potentially
stretching the first sample in tracks that start later than the
first one).

Some software does not support edit lists at all, the adobe flash
player seems to be one of these. This results in AV sync errors when
edit lists are used to adjust AV sync.

Some players, such as QuickTime, don't respect the duration for
audio packets, so if an audio track starts later than the video
track and the first audio sample gets a duration longer than the
actual amount of data in it, the result will be out of sync.

Based on patches by Michael Niedermayer.

This is the same logic as is invoked on AVFMT_TS_NEGATIVE,
but which can be enabled manually, or can be enabled
in muxers which only need it in certain conditions.

Also allow using the same mechanism to force streams to start
at 0.
