Merge remote-tracking branch 'qatar/master'
* qatar/master: (34 commits) dpcm: return error if packet is too small dpcm: use smaller data types for static tables dpcm: use sol_table_16 directly instead of through the DPCMContext. dpcm: replace short with int16_t dpcm: check to make sure channels is 1 or 2. dpcm: misc pretty-printing dpcm: remove unnecessary variable by using bytestream functions. dpcm: move codec-specific variable declarations to their corresponding decoding blocks. dpcm: consistently use the variable name 'n' for the next input byte. dpcm: output AV_SAMPLE_FMT_U8 for Sol DPCM subcodecs 1 and 2. dpcm: calculate and check actual output data size prior to decoding. dpcm: factor out the stereo flag calculation dpcm: cosmetics: rename channel_number to ch avserver: Fix a bug where the socket is IPv4, but IPv6 is autoselected for the loopback address. lavf: Avoid using av_malloc(0) in av_dump_format dxva2_h264: pass the correct 8x8 scaling lists dca: NEON optimised high freq VQ decoding avcodec: reject audio packets with NULL data and non-zero size dxva: Add ability to enable workaround for older ATI cards latmenc: Set latmBufferFullness to largest value to indicate it is not used ...
