I have found that -oac copy produces incorrect results in some particular cases.
Here is a simple way to test the bug; take a dvd with LPCM audio and do:
mencoder dvd://1 -ovc frameno -oac copy -aid 160 -frames 500 -o file.avi
Now play file.avi: mplayer file.avi
You will get only loud noise.
I propose fixing this by refusing audio streamcopy if sh_audio->format does not fit into mux_a->wf->wFormatTag, patch attached.
I would like a different patch. If sh_audio->format does not fit into mux_a->wf->wFormatTag issue a WARNING , but still do audio streamcopy.
Agree. The patch can either make it a warning or an error, but it needs to add -ftwocc options (like -ffourcc) to force a new tag.. Then we can make new twocc's for storing random crappy audio formats in avi.. :) Rich
