This is necessary to get the right timestamp offset for content
that starts with dts != 0.

This currently only helps when writing fragmented files with a non-empty
moov atom. When writing an empty moov atom, we don't have any packets
yet, so we don't know the starting dts for the tracks.

This makes sure that audio preroll for e.g. AAC is signaled correctly.

Previously we only wrote the edit list correctly if we had negative
dts but started with pts == 0 (e.g. for video with B-frames).

In these cases, only drop dts. Because if we drop both we have no
timestamps at all for some files.

This improves playback of HLS streams from GoPro cameras.

Make tcp and tls urls near-interchangeable.

Prevent a NULL-pointer dereference.

Trying to write to a stream id larger the the maximum requested is
a programming error, still there is no reason to leave a
reachable abort() in the codebase.

Print the timestamp values and not just the stream index.

Wrap the function calls in a similar fashion to how it's being done
with the critical section API.

This matches the -map option which requires '%d:%d' format.

Also always report pixel format.

Speed up the overall compilation time.

This makes the field consistent with AVInputFormat.mime_type and the
argument type of av_match_name.

The spec requires this.

Fixes uninitialized reads on some samples.

Remove now unnecessary initialization of the whole merge candidate list.

The caller expects the MV to always be initialized.
