Summary0018377: M4A: Some downloaded M4A can crash MM
DescriptionSome downloaded M4A can crash MM.

test 1: 2507 clean install, no codec pack, just takes long time to skip thru them and report missing codec. No crashes in 2507 while 2433 crashes more often.

test 2: same 2507 clean install, codec pack installed, takes much longer to determine files are unplayable and if you try to play them again MM5 crashes with white screen of death.

LOGS of both test cases and sample files sent offline.

The files are fragmented MP4s (MP4 dash). Such files do not contain needed info in the header, so MM fully parses whole file, all fragments, just to find out the duration and number of samples, this is what takes some time, so slower skipping is expected. Windows codec is not able to play such file, that is why our codec pack is needed.
The crash is inside our f_aac_plugin during parsing before playback, analyzing.
