The code before was unsafe, had a race condition and could crash.

This fixes changing channels
It possibly might cause regressions but i cant avoid this without having a test
case that needs the locking code.

It may be needed to use values greater than 72, and in general greater
than an arbitrary big value. Let the user choose what's too big for
her.

Authorship of the decoders is elvis / maxim. For more details see previous

This change fixes a bug where seeking doesn't work properly for
matroska files that have the CUES element before the first cluster.
This bug was accidentally introduced a few months ago by my deferred CUES
loading patch<http://git.videolan.org/?p=ffmpeg.git;a=commit;h=31ad14c21e0735387ba8082c6e3436241f7ccfc8>
.

When the CUES element appears before the first cluster in the file, the data
is parsed and placed in matroska->index but that data is never added to the
seek index. Currently the transfer from matroska->index to the seek index
only happens when matroska_parse_cues() is called.
Matroska_parse_cues() only gets called on a seek if cues_parsing_deferred is
set. Cues_parsing_deferred only gets set if parsing the CUES requires
seeking past the first cluster. There is no code to handle the case where
CUES is before the first cluster.

This fix essentially restores the matroska->index processing that was
happening at the end of matroska_read_header() before I made my CUES
deferral change. In the case where CUES is before the first
cluster, matroska->index will have data and the seek index will be updated.
In the case where CUES is later in the file, matroska->index will be empty
and cues_parsing_deferred will be set so loading will happen later.

This is a raw demuxer for the AAC LATM decoder and thus limited to
single stream LOAS.

CODEC_CAP_DELAY set.

Make the iff demuxer send the whole audio chunk to the decoder as a
single packet and move stereo interleaving from the iff demuxer to the
decoder.

The install directory being deleted might not be present if the build failed.
This can lead to annoying error output if the FATE client is run as a cronjob.

Since fate.sh can be run from cron, silent commands are preferrable.

This makes the RTMP writing code able to handle FLV data
fed in arbitrarily small or large chunks, with multiple
consecutive packets in one write call, or having the FLV
packet header split over numerous write calls.

When used in conjunction with the flv muxer, the AVIO buffer
size still needs to be large enough to fit the initial metadata
packet though, since the size of that packet is written with a
seekback.

sqrt(-1) returns "some NaN", it's not specified which exactly.

Change flags2 options to supported libx264 private options.

drawbox() expects a color specified in RGBA format, while the code was
providing a color with the components specified in the same order of
the input pixel format.

In particular, fix box coloring with AXXX RGB formats.

This avoids overflow errors when the considered x and y values are
negative, as required by the incoming patches.

Beautify.
