[FFmpeg-user] getting 'av_interleaved_write_frame(): Operation not permitted with mp4 files

Thu Jul 21 19:39:56 CEST 2011

After some more experimentation, it appears that lack of disk space was causing these problems!... 
Would be great if ffmpeg could be made to present informative error messages when appropriate. For example, I've already gone through 2 distinct cases (both due to lack of disk space):
1- Error: IO Error
2 - 'av_interleaved_write_frame(): Operation not permitted'

This would save ffmpeg users (especially inexperienced ones, like myself)  tons of time (which would otherwise be wasted trying to figure out what on earth the error messages actually mean). If this feature hasn't been requested yet, and there is a way to request it you can point me to, please let me know. Thanks,

-Patricia

Subject: [FFmpeg-user] getting 'av_interleaved_write_frame(): Operation not permitted with mp4 files

Hi,
I've done research on this problem but saw no obvious solutions being offered (plus, it is not clear whether this is an ffmpeg bug or not). I need to automate the run of ffmpeg to convert uploaded user files (mp4 which are about an hour long) to an ipod-compatible format. I keep getting this error message either at the beginning of the encoding, or close to the beginning (in one ocassion, running under 'root', I was able to get ffmpeg to process the file for a while, perhaps a few minutes, before it gave out the same error message). 
Here is the complete transcript of one of these runs (BTW, there are other error messages from ffmpeg as I'm still trying to get the parameters right here :-(, but I don't think these have anything to do with the one I am mentioning).  Would definitely appreciate any help with this. Thanks in advance!
