You are welcome! :-)

1. No, as stated in a previous mail XBMC is currently based on ffmpeg
version 0.10.2 that works perfectly well on *Apple IOS (iphone/ipad)* thus
this is the first time we test xbmc with the ffmpeg 2.1 libraries.

But that's not my point, let me refrase:

a) What is the minimum *platform* (win32, linux, etc) test requirement for
a new ffmpeg release , i.e does IOS count a standard platform for new
ffmpeg eeleases or is release 1.2 previously untested on IOS?
b) Who is normally maintaining the apple ios (iphone/ipad) platform for

Only trac is supported (and suggested) on this mailing list.

2. Let me refrase the question: Since Måns Rullgård at libav has done most
work on the ARM optimizations, which bug trackers is best to use a) the
libav.org bug tracker or b) the ffmpeg.org bug tracek or c) both bug

3. Ok, will do!

4. Sorry, you have to be a bit more specific on this one since I'm not a
ffmpeg core developer. FATE is a rather complex automated testing
environment and IMHO this aught to be performed by a skilled IOS mainterner
at ffmpeg.org

5. --disable-asm works.

Is this a regression, ie does it work with any older version?

6. Se point 1 above or read this mail conversion from start.
