 Hello,

 I am using ffmpeg latest framework build from
 http://www.osxexperts.net/ffmpeg/ffmpegexperts.html for an iOS app.

 My app requires to display live camera feeds of 8 channel.
 When I frequently change screen mode for example full screen for some
 channel then I got crash on ff_put_h264_chroma_mc8_neon.

 Please let me know should I change framework build or it is the problem of
 iOS code.

 below is the error
