[FFmpeg-devel] avformat/mov: improve qt metadata reading and writing

Hi all, this has been brought up before, the MOV muxer/demuxer currently does not support all possible datatypes that are allowed in keys/mdta style metadata. This is specified here: https://developer.apple.com/library/mac/documentation/QuickTime/QTFF/Metadata/Metadata.html#//apple_ref/doc/uid/T

[FFmpeg-devel] [PATCH] avcodec/proresenc_anatoliy: change quantization scaling to floating point to utilize vectorization

Quantization scaling seems to be a slight bottleneck, this change allows the compiler to more easily vectorize the loop. This improves total encoding performance in my tests by about 10-20%. Signed-off-by: David Murmann --- libavcodec/proresenc_anatoliy.c | 12 1 file changed, 8
