This copies the behaviour of the amr demuxer.

All current usages of it are incompatible with localization.
For example strcasecmp("i", "I") != 0 is possible, but would
break many of the places where it is used.
Instead use our own implementations that always treat the data
as ASCII.

this should allow some simplifications in some applications.

lavf: Do not set cur_dts to undetermined before first_dts has been calculated as this would upset the start_time and first_dts calculation.

The new decoder is much smaller and has better code quality.

fixes memleak with raw gsm demuxing.

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

Add some parameters to existing function documentation.
Remove some unneeded documentation.
Convert some static function documentation to non-doxygen style.

This fixes a bug where the whole buffer was returned as decoded audio due to
*data_size not being set to zero and the return value being >= 0.

we only support decoding of mono imc

ask for a sample if not mono

Ease readability, improve exactness.

Current implementation fades to 0. This implementation fades to 16 for
YUV formats that contain CCIR601/709 video levels. RGB and YUVJ
formats are not altered.

Streams from RTSP or SDP that do not match an allowed type will
be skipped entirely, which allows video-only or audio-only
streaming from servers that provide both.
