[FFmpeg-devel] [PATCH] fix clicks in ADPCM IMA AMV decoder

[Vladimir Voroshilov]

Hi, All

Attached simle patches fixes clicks in audio when playing AMV files.

If i'm undestanding things correctly, predictor is first PCM sample to
start decoding from and thus it should be signed short value.

First patch with "both" suffix fixes assignment for both AMV and SMJPEG, while
second (marked as "case") adds special case for handling only AMV.

If preferred patch is ok please apply it.

P.S. Patches are simplified versions (with removed duplicated code)
version of patches used in amv-codec-tools project. Original code was
written by Dobrica Pavlinusic.
