d92550d191 lavf: eliminate ff_get_audio_frame_size()
It is basically a wrapper around av_get_audio_frame_duration(), with a
fallback to AVCodecContext.frame_size. However, that field is set only
when the stream codec context is actually used for encoding or decoding,
which is discouraged.

For muxing, it is generally the responsibility of the caller to set the
packet duration.
For demuxing, if the duration is not stored at the container level, it
should be set by the parser.

Therefore, removing the frame_size fallback should not break any
important case.

194be1f43e lavf: switch to AVStream.time_base as the hint for the muxer timebase
Previously, AVStream.codec.time_base was used for that purpose, which
was quite confusing for the callers. This change also opens the path for
removing AVStream.codec.

The change in the lavf-mkv test is due to the native timebase (1/1000)
being used instead of the default one (1/90000), so the packets are now
sent to the crc muxer in the same order in which they are demuxed
(previously some of them got reordered because of inexact timestamp
conversion).

0c1959b056 lavf: add AVFMT_FLAG_BITEXACT.
Use it instead of checking CODEC_FLAG_BITEXACT in the first stream's

Using codec options inside lavf is fragile and can easily break when the
muxing codec context is not the encoding context.

d9ae1031f5 lavf: improve handling of sparse streams when muxing
Currently ff_interleave_packet_per_dts() waits until it gets a frame for
each stream before outputting packets in interleaved order.

Sparse streams (i.e. streams with much fewer packets than the other
streams, like subtitles or audio with DTX) tend to add up latency and in
specific cases end up allocating a large amount of memory.

Emit the top packet from the packet_buffer if it has a time delta
larger than a specified threshold.

Original report of the issue and initial proposed solution by
mus.svz@gmail.com.
