Needs a sample. An option or setting for probe size might be a good idea Spotify comments ---------------- In mp3 files, id3v2 tag with huge cover art causes the probe code to not identify valid mp3 files as mp3. Increase default buffer so that probe can see mp3 frames.
Might not be a priority as we could use an option to change this. The reason we did it this way historically is to make sure ffmpeg in different services behaved the same. /Tomas
