hmm. did you tried it with other players?
unfortunatelly most damaged avi files are unplayable with mplayer or any
other player. reconstructing an avi index or play it without inde xis near
impossible if there is a broken chunk header somewhere :(
the only way what i can imagine is some brute-force thing, i mean skip 1
byte, try to demux few chunks, if not ok then jump back, skip 2 instead of 1
bytes, try again and again until you get a chain of proper chunk headers...
it shouldn't be done realtime as it takes long...
maybe implementing a prog called avifix, based on libmpdemux...
