The result remains lossless. If the prediction coefficients are lowered, the residual of the prediction increases. This means the file gets a little bigger, but the data is still all there. If it gives up on searching for suitable LPC coefficients, it uses a verbatim subframe instead of an LPC subframe. That means all data is stored as unencoded PCM, with no form of prediction whatsoever. This results in (usually a large) increase in storage space needed, but this is still lossless. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
