We have been doing extensive testing on H264 playback in both FLV and MP4 containers on Android AIR 3.2 / 3.3 (beta 3) for ICS. The process is documented here:
Android AIR 3.2 / 3.3 (beta 3) H264 playback (both in FLV and MP4 container) on Android 4 is severely broken.
Video object (not StageVideo) with H264 content is:
1) not playing videos consistently ("NetStream.Play.Stop" is triggered to early) so the movie stops before the end is reached. This also happens on Android 3. Note! The bug is not in AIR 3.1.
2) not supporting filters (video frame is being scaled). Only Android 4 (ICS).
3) not supporting seeking when video is paused (video frame is not being updated). Only Android 4 (ICS).
Is there any known workarounds for these bugs?
