Hello.
I download a Movie from the Internet but I can't play it?
I use below command to check it :

ffmpeg -v error -i my.avi -f null -

it show me :

[mpeg4 @ 0x175dd00] hmm, seems the headers are not complete, trying to guess time_increment_bits

How can I fix it?

Hi there,

I don't know ffmpeg well enough to go into these messages in detail. But it looks as though ffmpeg finds an mpeg4 video stream (what variant of mpeg4? H.264?) and an AC3 audio stream in the file. Assuming the video is actually H.264, this is an unusual combination for an avi container. Does ffmpeg rely too much on the file extension? Have you tried to rename the file to *.mp4 and repeat?

What I would do (because I'm not familiar with ffmpeg) is to open the video file in Avidemux, and then look under File/Properties what it really is. Avidemux opens a great variety of video formats, even some that aren't valid, like AC3 audio in an AVI container. As an alternative, I might just try to play the file with VLC (Videolan) and have a look at Tools/Codec Information to find out the actual video and audio encoding.
Then think about it and see what I can do with it.

is it a real file ? and not a windows virus ?
is it DRM'ed ?
if it is a real movie and a legal one
redownload it

what does the file command output ?

If the header is corrupted or incomplete, you can try this from this site
http://falcon1986.wordpress.com/2010...quick-command/

Even though the article is around ubuntu, the mencoder command is available in many linux distros preinstalled or available to download from the repos.

^ seems to be a windows only program (is that an ad ?) ...
whois already provided a way to fix the indexing using mencoder (which seems easier/cheaper by the way).

my thinking is that if he downloaded a torrent maybe it's not really an avi file. maybe it is a mis-labeled *.mkv/*.mpg*/.mov/*.wmv/*.qt/...
stuff like that is common on file sharing sites since they aren't meticulous about quality.

ffmpeg and aviconv are both pretty good. Either the poster gave you validate and repair capabilities, or they did not. Also, either the file is still available, and a legit file, or it is not. The wariness of JohnVV is a valid point. It might not be an actual movie file.

In cases like these I put in only so much horsepower and then either try to find the file from another source, conclude that it was not an actual movie, or that I just don't have enough of a valid file to repair.

I rename it and use other tools like VLC too but not worked

Not Worked

we're probably chasing ghosts. what is the result of this:

@ jokar.mohsen

I agree with schneidz. Using the file command is the next logical step to identifying the video or unknown file.

fyi, output should look like:

Documents.mp4: RIFF (little-endian) data, AVI, 720 x 400, 23.98 fps, video: XviD, audio: Dolby AC3 (6 channels, 48000 Hz)

document.mp4: RIFF (little-endian) data, AVI, 720 x 400, 23.98 fps, video: XviD, audio: Dolby AC3 (6 channels, 48000 Hz)

my limited understanding is that the avi container is unable to hold more than 2 audio channels ?

maybe try to convert it to an mkv ?


also try playing it with mplayer in the terminal and see if it prints out any error messages ?
