Repair OGG files that have been extracted without a header

Question

I have recently used a tool called FSBextractor to extract audio from a videogame. The program warns me that the files do not have headers and will not be playable. Upon extraction, the files are indeed not playable (using MPC-HC).

Is it possible to repair these files? How unique is an Ogg Vorbis header? Is it possible to extract a header from another file and insert it into the broken files?

Answer 1

Recently I recorded a stream using:

mplayer -dumpstream  "https://radio.tildeverse.org/radio/8000/radio.ogg" -dumpfile "/home/adamd/temp/StreamDump.ogg"

When completed it was playable with occasional skips and errors. Errors were Error parsing the packet header.. Progress indication and the ability to move to specific locations in the playback did NOT work.

Fixed by running: ffmpeg -i StreamDump.ogg SD.ogg

Perhaps it will work for you.
