Merge remote-tracking branch 'qatar/master'
* qatar/master: (36 commits) adpcmenc: Use correct frame_size for Yamaha ADPCM. avcodec: add ff_samples_to_time_base() convenience function to internal.h adx parser: set duration mlp parser: set duration instead of frame_size gsm parser: set duration mpegaudio parser: set duration instead of frame_size (e)ac3 parser: set duration instead of frame_size flac parser: set duration instead of frame_size avcodec: add duration field to AVCodecParserContext avutil: add av_rescale_q_rnd() to allow different rounding pnmdec: remove useless .pix_fmts libmp3lame: support float and s32 sample formats libmp3lame: renaming, rearrangement, alignment, and comments libmp3lame: use the LAME default bit rate libmp3lame: use avpriv_mpegaudio_decode_header() for output frame parsing libmp3lame: cosmetics: remove some pointless comments libmp3lame: convert some debugging code to av_dlog() libmp3lame: remove outdated comment. libmp3lame: do not set coded_frame->key_frame. libmp3lame: improve error handling in MP3lame_encode_init() ...
