Forcing a manual conversion to the same output format as the auto-scaler avoids the error, so looks like a config error rather than the conversion itself I don't have time to trace it at present. Only wanted to get the immediate use-case fixed. Thanks, Gyan ___ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
