This makes me think you are not decrypting the segments correctly, I had understood the specs to mean that if it isn’t specified, the IV needs to be incremented for each segment (so you would need to use 0x00000000000000000000000000000000 for the first segment, 0x00000000000000000000000000000001 for the second, etc. based on the initial media sequence number of 0). I don’t think the missing picture message at the end is unexpected, since the stream was cut arbitrarily after all, this is the result of my attempt at decrypting each segment with openssl and using cat to put them together (ffmpeg wasn’t used, except to test the file). https://media.kumowoon1025.com/videos/cat.ts <https://media.kumowoon1025.com/videos/cat.ts> _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
