Don't mark all streams as finished, instead make sync_opts keep track of the
stream's duration, and set recording_time to it, same as in transcoding paths.

Adds demuxer for Square Enux SCD files.
Based off [1] and personal investigation.
This has only been tested against Drakengard 3 (PS3) *_SCD.XXX files
(big-endian). As it is highly likely that FFXIV (PC) files are little-endian,
this demuxer is marked as experimental until this can be confirmed.

Currently they are ordered as-written (i.e. by increasing position);
in case av_interleaved_write_frame() is used, this is (mostly)
the same as ordered by increasing dts.
Yet the Matroska specification strongly recommends (SHOULD) that
the CuePoints be sorted by CueTime. mkvalidator warns when they are
not. Therefore this commit sorts them accordingly.

Freeing the new H.264 specific fields has been forgotten.
(This leak only appears in case the encoder has not been completely
drained.)

Up until now, it has only been freed when the QSVFrame is reused,
so that the last one contained in it leaked at the end.
Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
Since commit 3bbe0c210b, the Payloads
array of every QSVFrame leaks as soon as the frame is reused;
the leak is small and not very noticeable, but if there is an attempt
to use said array the ensuing crash is much more noticeable.
This happens when encoding H.264 with A53 CC side data.
Furthermore, if said array can not be allocated at all, an AVFrame
leaks.
Fix all of this by not allocating the array separately at all; put it
in QSVFrame instead and restore the Payloads array upon reusing the
frame.
Finally, use av_freep() instead of av_free() to free the payload
entries.

If fifo_thread_recover() succeeds immediately after
fifo_thread_dispatch_message() fails, the dts of the packet is scaled
twice, causing cur_dts to be abnormally large and "Application provided
invalid, non monotonically increasing dts to muxer in stream" to occur
repeatedly.
Steps to reproduce:
1. ffmpeg -f lavfi -i testsrc -c:v libx264 -map 0:v -flags +global_header -f fifo -fifo_format flv -attempt_recovery 1 -recover_any_error 1 rtmp://example.com/livekey
2. set a breakpoint on fifo_thread_recover
3. force disconnect from the rtmp server
4. wait for break
5. reconnect to the rtmp server
6. resume execution of ffmpeg

FLV AMF tags have a 24bit field for timestamps plus an 8bit for extended
timestamps.
All FLV AMF tags except when we write metadata handle this correctly
using the put_timestamp function.
Until now when writing metadata we were only using the first
24 bits and thus the timestamp value was wraping around 4 hours 40
minutes (16,800,000 ms, max 24 bit value 16,777,216) of playback.
This commit fixes this applying this same function put_timestamp
for the metadata FLV tag.

This was almost completely redundant. The only functionality that's no longer
available after this removal is the videotoolbox_pixfmt arg, which has been
obsolete for several years.
In order to know that the earlier code did not use uninitialized
values one needs to know that the lowest four bits of each used
value of pframe_block4x4_coefficients_tab do not vanish identically.
E.g. Coverity did not get this and warned about it in ticket #1466632.
Fix this by slightly rewriting the code.

Due to reasons, mpv doesn't pass filename when probing. mpv also sets
default probescore threshold to 26. Since the current jpeg_probe
implementation returns 25 until EOI, it means that the whole image needs
to be probed to succeed. Worse, the whole image is not passed at once;
increasingly large buffers are tried before that. Adding it up together,
if many demuxers are enabled, moderately large JPEG files (few MB) can
take several seconds to open, despite taking less than 1 second to
actually decode.
Therefore, adjust the heuristic to be more optimistic if proper JFIF or
Exif segments are found. While not strictly required, the vast majority
of JPEG-ish files have one or the other or both.

The check for m->size >= 0xF000 is intended to avoid skipping too much
garbage data between JPEG frames in test_roman (thus missing next SOI),
but it erroneously also skips valid markers between SOI and SOS. Instead
of this, we should simply skip parsing markers other than SOI after EOI.
That way, we will not accidentally skip over SOI due to some garbage
between frames. There is still a small risk of encountering FFD8 in the
garbage data, but the chance of this is fairly low.

For most check_bitstream() functions this just avoids having
to dereference s->streams[pkt->stream_index] themselves; but for
meta-muxers it will allow to forward the packet to stream with
a different stream_index (belonging to a different AVFormatContext)
without using a spare packet.
