There must have been some kind of local corruption.

I've just emptied the source tree and re-downloaded from SVN and all is
well.

Apologies for the waste of bandwidth, and happy New Year 2007 to all!

It's what happens when you have made local changes to the file, and an update 
brings conflicting changes in from the repository. The usual procedure is to 
fix the file so that it's correct and run 'svn resolved file' to tell SVN 
it's OK. Deleting the file and running update again, or running 'svn revert 
file' is a quick and easy way if you don't mind losing your local changes.

I made no changes to the "configure" script at all.

Thanks for the information.

The reason we come up with new versions is not to fix bugs.  It's
absolutely not.

video delay in relation to audio

Hello,

Is there a switch to offset the audio in relation to the video of an
mpeg file using ffmpeg?  The source file has a slight video delay and I
wish to correct this in my final production.

Thanks in advance,

Tim

           Set the input time offset in seconds.  "[-]hh:mm:ss[.xxx]" syntax
           is also supported.  This option affects all the input files that
           follow it.  The offset is added to the timestamps of the input
           files.  Specifying a positive offset means that the corresponding
           streams are delayed by 'offset' seconds.

Thinking about this again -- if you have 1 mpeg container with 1 audio
stream and 1 video stream and you want to offset the audio and video by some
amount, I think the first step is going to be to split the audio and video
streams. Then you could use ffmpeg to combine them or mplex. Both have

Frame sizes

I need to obtain the sizes of the I, P and B frames of the video of a DVD. 
Is this possible with ffmpeg?

Thank you, that was exactly what I was after.

I have done this with the -vn acodec copy and -an vcodec copy switches,
producing the necessary files to remultiplex.  One concern I have is
that the vcodec copy doesn't appear to produce an exact copy:

$ file original.mpg
video.mpg: MPEG sequence, v2, program multiplex

$ file vcodec-copy.mpg
ffmpeg.mpg: MPEG sequence, v1, system multiplex

Is this something to be concerned about?

Thanks, Tim

newbie

Hi,

I have downloaded ffmpeg and want to convert video file types avi,mpg,mpeg,mov and wmv to flash types flv/swf.

I can do this with 3rd party tool but I want to do this from a program eg php script.

q) can ffmpeg do this for all these types or do i need further programs to do this.

q)Where are instructions on how to convert because I can't seem to find this exact information that
explains what you need. Just saying ffmpeg ww.avi -ar etc what are all the commands mean?
