The esds descriptor I got from ISO 14496-1 so I'm not completely sure about it but it did work on the first mpeg4 video I tried.Ĭan anyone offer an suggestions as to how I might go about figuring this out? From what I can see, QuickTime does not offer any sort of debug logging and I'm somewhat stuck. One of the areas where I suspect their might be a problem is the mp4v atom and it's esds child atom. I've also successfully created two other videos (1 mpeg4 and 1 h264) with the same multiplexer library and both those videos played fine in WMP, VLC and QT. I've double checked all the atoms and their fields and everything looks correct. The video ( test1.mp4) I've created successfully plays in Windows media player and VLC but will not play in Quicktime. I'm writing a multiplexer which takes mpeg4 frames (and h264) and puts them in an mp4 container.
