Merge remote-tracking branch 'qatar/master'
* qatar/master: (44 commits) replacement Indeo 3 decoder gsm demuxer: do not allocate packet twice. flvenc: use first packet delay as global delay. ac3enc: doxygen update. imc: return error codes instead of 0 for error conditions. imc: return meaningful error codes instead of -1 imc: do not set channel layout for stereo imc: validate channel count imc: check for ff_fft_init() failure imc: check output buffer size before decoding imc: use DSPContext.bswap16_buf() to byte-swap packet data rtsp: add allowed_media_types option libgsm: add flush function to reset the decoder state when seeking libgsm: simplify decoding by using a loop gsm: log error message when packet is too small libgsmdec: do not needlessly set *data_size to 0 gsmdec: do not needlessly set *data_size to 0 gsmdec: add flush function to reset the decoder state when seeking libgsmdec: check output buffer size before decoding gsmdec: log error message when output buffer is too small. ...
