is 'avc1' a supported video file codec?
After seeing the Apple message that some codecs will not be supported in future OS releases, I've begun to identify which of my 6TB of video will need to be dealt with. One very common codec is 'avc1' and it seems possibly the same as H.264/MPEG-4 AVC. What is 'avc1' and will it be supported?
