Summary0014960: Common Extension issues
DescriptionThere are common extension issues with playback where MMW assume it is one extension and tries to play it but actually it is different one where MMW should automatically fall back in such cases.

One most common issue is when Mp4 file contains only Audio (eg. m4a file) and MMW can't play it at all and report missing codec no matter what is installed.

In such known case MMW should fallback to M4A codec and try to play the file.

Fixed in build 1876. Merged to MM5 build 2116.
Only the mentioned sample fixed as it makes sense, from now on, in_mfaudio can handle also MP4 with audio only (video checking implemented, so it will not steal playback of MP4 videos). Plugins cannot handle this generally, because we have scanning and playback extension oriented, so it is needed to have correct extension. It could be solved by some universal format checking and fixing tool/functionality.
