[FFmpeg-devel] [PATCH] fix clicking sound in xa-adpcm

[Alexander Strange]

The XA ADPCM decoder resets the last sample predictors to 0 after  
every frame.
This is wrong, and causes loud clicking constantly in all my samples.  
Attached patch fixes it.

I can't tell if seeking is affected, since the STR demuxer can't seek
in ffplay (not sure why) and can't be remuxed (no codec_tag).
