Hello! Attached patch makes the ICO demuxer return EOF instead of EIO when the end of the file is reached. Currently, if you try to parse an ICO file, it will always result in ffmpeg outputting an error because of this. --Michael Bradshaw 0001-Return-EOF-for-ICO-when-the-end-is-reached.patch

Thanks for checking. I also check the AVFMT_FLAG_FAST_SEEK flag with parsing headers, to fill the seektable into index entries only if AVFMT_FLAG_FAST_SEEK flag is on. If the AVFMT_FLAG_FAST_SEEK flag is not enabled, it will seek in original way. 2015-09-25 10:37 GMT+08:00 Michael Niedermayer
