Merge remote-tracking branch 'qatar/master'
* qatar/master: Add LATM demuxer avplay: flush audio decoder with empty packets at EOF if the decoder has CODEC_CAP_DELAY set. 8svx/iff: fix decoding of compressed stereo 8svx files. 8svx: log an error message if output buffer is too small 8svx: check packet size before reading the initial sample value. 8svx: output 8-bit samples instead of 16-bit. 8svx: split delta decoding into a separate function. mp4: Don't read an empty Decoder Config Descriptor fate.sh: Ignore errors from rm command during cleanup. fate.sh: Run git-pull in quiet mode to avoid console spam. Apple ProRes decoder rtmp: Make the input FLV parser handle data cut at any point rv34: Check for invalid slices offsets eval: test isnan(sqrt(-1)) instead of just sqrt(-1) Conflicts: Changelog libavcodec/8svx.c libavcodec/proresdec.c libavcodec/version.h libavformat/iff.c libavformat/version.h tests/ref/fate/eval Merged-by: Michael Niedermayer <michaelni@gmx.at>
