The actual size of uncompressed buffer returned by uncompress() may be
smaller than expected, so abort decoding in such cases.

Passing a cutoff value < sample_rate/256 will cause a crash.
Also, values >20000 will have no effect and 20000 will be used anyway.

Prior to this change max number of channels for float data which was
going to be correctly decoded was 32, which is rather small
considering that exr allows multiple channel layers.

The whole point of ff_alloc_packet2 is to not bloat code with

This fixes the compiler error "cannot convert from 'BlockNode' to
'int16_t'".

This was unnoticed on linux, since stdlib.h apparently includes
files declaring the pthread_mutex_t and pthread_cond_t types.

The pivot has to lie between 0 and base.
Check of ==base is insufficient.
Thus replace it by a proper check.

Fixes out of array write.

This change introduces a basic decoder for 3GPP Timed Text subtitles,
also known as TX3G, Quicktime subtitles, or "movtext" in the existing
code.

This initial change doesn't attempt to parse styling information,
and just reads the plain text of the subtitles. I intend to add
support for styles eventually, but it's challenging due to a lack
of existing players that support them.

Testing gives 25-30% gain on HD clips with two threads and
up to 50% gain with eight threads.

Sliced threading uses more memory than single or frame threading.

Frame threading and single threading keep the previous memory
layout.

The values are listed if setting them fails.
Using "-preset help" or "-preset list" have that effect.

Work done for SOCIS 2011.

we are not going to use.

Only compressed files where affected by this bug.
