[Mp4-tech] small corrupted block showing from ISO/IEC 14496-2 Simple Profile bitstream

[John Lam]

Dear all,
I'm now using a hardware MPEG-4 video codec conformed to ISO/IEC 14496-2 
Simple Profile, I put the encoded bitstream into a MP4 file format. When 
I play it with QuickTime player 6.3, some small corrupted blocks can be 
seen, the corrupted patterns (in a block) are similar and the location 
of the blocks seems random for each frame. I want to know is there 
something wrong of the generated bitstream. Here attach a zipped file 
containing two snapshots from QuickTimer Player 6.3. I don't know 
whether I send the attachment to the mail group. If anyone may have idea 
on it, I can send you the attachment and the whole MP4 file to you 
directly. Thank you!
