I don't know anything about the code you are working with, especially iOS. What you will need to do is set GST_DEBUG to get debugging info on the proper plugin(s). You could start with GST_DEBUG=*:2 which will give you some debugging info on all plugins. Look to see what plugins look 'interesting' and adjust the value. The higher the number the more output you get. The syntax is: GST_DEBUG=ModuleName:level;Module2:level2;etc. I don't know how to set an environment variable in iOS. Sorry I can't give you more help. <div class="gmail_quote">On Tue, Oct 23, 2012 at 11:04 AM, rpappalax <<a href="mailto:rpappalax@gmail.com" target="_blank">rpappalax@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> That makes sense. 狢've looked through coremediabuffer.c, corevideobuffer.c and the other apis in applemedia, but I'm still not sure how I might isolate where this buffer misalignment is taking place. 狢'd appreciate any guidance on this you'd be willing to provide. Also, since I never saw this issue prior to the upgrade to iOS6, would there be a way to isolate if the issue were within the AVFoundation itself?
