1384df6419 lavf: Add an option for avoiding negative timestamps
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.

b263f8ffe7 lavf: add AVFormatContext.max_ts_probe
It allows to configure how long will avformat_find_stream_info() wait
to get the first timestamp.

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

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.

596e5d4783 lavf: Add a flag to enable/disable per-packet flushing
This is enabled by default and can be disabled with
"-fflags -flush_packets".

Inspired by a patch from Nicolas George <nicolas.george@normalesup.org>.

681ed00099 avf: introduce nobuffer option
Useful in cases where a significant analyzeduration is
still needed, while minimizing buffering before output.

An example is processing low-latency streams where all
media types won't necessarily come in if the
analyzeduration is small.

4fa57d524f libavformat: Set the default for the max_delay option to -1
Make the muxers/demuxers that use the field handle the default
-1 in the same way as 0.

This allows distinguishing an intentionally set 0 from the default
value where the user hasn't set it.
