In testing, the file output plugin gave a max buffer size of about 20 million
frames, which is way more than what is really needed and causes a memory
allocation error on my system.

buffer_size/4 is the value used by aplay. This fixes output to null
devices, e.g. writing ALSA output to a file.

Set DV packet durations using fields_per_frame.
This requires turning gxf_stream_info into the demuxer's context for access to the value in gxf_packet().
Since MPEG-2 seems to work fine this done only for DV.

This reverts commit 2cf8355f98.
AVInputStream.nb_streams tracks number of streams found at the
beginning, new streams may appear that ffmpeg doesn't know about. Fixes
crash in this case.

Set the frame size when decoding DTS audio.
This has the side effect of fixing the computation of timestamps for DTS-HD in compute_pkt_fields. Since frame_size is
not currently set, the duration of a frame is being guessed based on the streams bitrate. But for DTS-HD, the bitrate
currently used is the rate of the DTS core which is much different than the whole DTS-HD stream and leads to a wildly
inaccurate frame duration estimate.

EBML_STOP leaves matroska->current_id set. Then matroska_read_seek changes
the stream position without resetting current_id. The next
matroska_parse_cluster fails due to calculation of incorrect pos. So clear
current_id when avio_seek happens in matroska_read_seek.

Specifically crafted samples can reinit ogg->streams[] while
reading samples, and thus we should not cache old pointers since
these may no longer be valid.
