Michael Niedermayer 31fa50f3d9 avcodec/prosumer: Error out if decompress() stops reading data
if 0 is encountered in the LUT then decompress() will continue to output 0 bytes but never read more data.
Without a specification it is impossible to say if this is invalid or a feature.
None of the valid prosumer files tested cause a 0 to be read, so it is likely
not a intended feature.
