b800327f4c avformat/avformat: Add FFInputFormat, hide internals of AVInputFormat
This commit does for AVInputFormat what commit
59c9dc82f4 did for AVOutputFormat:
It adds a new type FFInputFormat, moves all the internals
of AVInputFormat to it and adds a now reduced AVInputFormat
as first member.

This does not affect/improve extensibility of both public
or private fields for demuxers (it is still a mess due to lavd).

This is possible since 50f34172e0
(which removed the last usage of an internal field of AVInputFormat
in fftools).

(Hint: tools/probetest.c accesses the internals of FFInputFormat
as well, but given that it is a testing tool this is not considered
a problem.)

08bebeb1be Revert "all: Don't set AVClass.item_name to its default value"
Some callers assume that item_name is always set, so this may be
considered an API break.

This reverts commit 0c6203c97a.

0c6203c97a all: Don't set AVClass.item_name to its default value
Unnecessary since acf63d5350adeae551d412db699f8ca03f7e76b9;
also avoids relocations.

1b3ec3c8ca avdevice/pulse_audio_dec: deprecate frame_size option
It does not do anything. Frame sizes can be controlled by using fragment_size.

b67ca8a7a5 avdevice/pulse_audio_dec: reduce default fragment size
Reduces default fragment size from the pulse audio default of 2 sec to 50 ms.
This also has an effect on the size of the returned frames, which will be
around 50 ms as well, making timestamps more accurate.

This should fix the regression in ticket .

Pulseaudio timestamps for monitor sources are still pretty inaccurate for me,
but I don't see how else should we query latencies from the library.

b83032899a Revert "avdevice/pulse_audio_dec: only set adjust latency flag if fragment_size is not set"
This reverts commit 7f059a250b.

Apparently adjusting latency makes a difference even if fragment size is specifed.

b2d0826513 avdevice/pulse_audio_dec: do not read undersized frames
Keep on reading fragments until we got fragment_size amount of data, otherwise
we might get frames with 1-2 samples only if pa_stream_peek is called slightly
less frequently than sample rate.

Note that fragments might contain a lot less data than fragment_size, so
reading multiple fragments to get fragment_size amount of data is intentional.
