This keeps cropping when remuxing from F4V to FLV.

Handle it in the same way as VP6F, except for the codec tag.

The plain VP6 format is vertically flipped compared to VP6F/VP6A.
Support for the plain VP6 format was added in 09d8c0ae831 (which
also introduced support for muxing VP6F properly in general).

Since 596e5d4783, this is not necessary anymore. It also allows to
actually disable the flushing, improving write performance (but
possibly giving worse latency in real-time streaming).

FLV does not support multiple audio or video streams.

The FLV muxer tries to update the header in write_trailer, which is
impossible if writing to a pipe or network stream. Don't write header
data if seeking to the header fails.

The compiler fails to figure out that enc->codec_type can only
have 3 different values.
Thus when an if/else is encountered it triggers on the possibility
of the else case has not initialized the flags variable.

According to its description, it is supposed to be the LCM of all the
frame durations. The usability of such a thing is vanishingly small,
especially since we cannot determine it with any amount of reliability.
Therefore get rid of it after the next bump.
Replace it with the average framerate where it makes sense.
FATE results for the wtv and xmv demux tests change. In the wtv case
this is caused by the file being corrupted (or possibly badly cut) and
containing invalid timestamps. This results in lavf estimating the
framerate wrong and making up wrong frame durations.
In the xmv case the file contains pts jumps, so again the estimated
framerate is far from anything sane and lavf again makes up different
frame durations.
In some other tests lavf starts making up frame durations from different
frame.

This removes the use of macro nesting in these code constructs, which
makes it easier to parse in pre-processors.

Encoder tag being used for muxer messages is confusing.
|
|
Also add missing trailing commas, break long codec_tag lines and
add spaces in codec_tag declarations.

The existing functions defined in intfloat_readwrite.[ch] are
both slow and incorrect (infinities are not handled).
This introduces a new header with fast, inline conversion
functions using direct union punning assuming an IEEE-754
system, an assumption already made throughout the code.
The one use of Intel/Motorola extended 80-bit format is
replaced by simpler code sufficient under the present
constraints (positive normal values).
The old functions are marked deprecated and retained for
compatibility.

It's supposed to be called only from (de)muxers.

This keeps the streams sychronized. The packets must be interleaved per-DTS.

Using AVCodecContext.frame_size is not reliable.

No application rely on this count being correct as far as
I know, but if we write a nonzero count value, it might just
as well be the right one.

Metadata currently is written only at the start of the file in normal
cases, when transcoding from a rtmp source metadata could be
written later and the offset recorded can exceed 32bit.

avio_flush can fail, in particular when used with the rtmp/librtmp

In the name of consistency:
put_byte -> avio_w8
put_<type> -> avio_w<type>
put_buffer -> avio_write
put_nbyte will be made private
put_tag will be merged with avio_put_str

This also lists the objects from those two libraries as internal (by adding
the ff_ prefix) so that they can then be hidden via linker scripts.
