Hi,

I just downloaded some tv epdisodes in supossibly avi format. (the file suffix states .avi)
When I try to play the file nothing happens. The message log looks like this:

I noticed the following two lines:

Code: Select all

ffmpeg debug: couldn't guess format
ps warning: this does not look like an MPEG PS stream, continuing anyway

Apparently something is wrong with the video, but I'm puzzled on how to solve the problem.
Any suggestions?

Thanx in advance!

Is it really an AVI file? It could possibly have been misnamed. Check by doing a 'file <filename>' in terminal, which will report file headers that should give you a clue to its origin. If OK, does it play in other media players?

Code: Select all

$ file 24_101__12.AM.to.1.AM--.avi 
24_101__12.AM.to.1.AM--.avi: data

I tried playing the file in Quicktime (responded with, this is no movie file), Mplayer (did nothing) and of course VLC none of them succeeded...

Might it be that the avi header is corrupted? Is there a way to repair such damage?

I have no idea. It seems to me that the file was never an AVI container to begin with, and if so, there is no header to repair (as file seems to indicate by reporting just 'data'). You could always try what I just did:

" just downloaded some tv epdisodes in supossibly avi format. (the file suffix states .avi)"

There are lots of spammers too. You need to know what you are downloading. I am guessing it is torrent file. Read the comments first. There may be warning posted by other users.

Yes, I did check the comments and found nothing pointing to any problems.

By the way I think I found what is causing the problem. I looked into the file with a hex editor and found that the RIFF (http://www.jmcgowan.com/avitech.html#Format) header is missing. Now it's just a matter of finding the right software to recreate the missing header.

Thanks everybody for the assistance.
