Converting Xvid avi's to dvd always fail

[sosnowski]

I've been trying to convert Xvid avi files to an dvd file.

They always fail.
There are several files and they all run into an error

"Couldn't read frame number......."

They hang there for a minuted then continue...
Seems like they stop encoding the video at that point and begin encoding the audio.
Then there are a ton of audio warnings

" WARN: audio sector out of range: ......."

Then it finishes up, creates the DVD folder with the AUDIO_TS and VIDEO_TS folders inside..
It also creates the .ac3, .m2v, and .mpg files.

All the files seem to work.
The audio .ac3 file seems like it got encoded all the way through,
however both video files (m2v and mpg) both get cut off.
I assume it stopped the video encoding when it reached the frame it couldn't read.

I have also tried to encode using iDVD, quicktime, Toast, and compressor.

With iDVD, Toast, and quicktime - it starts encoding and just completely quits sometime during the process.... no error message or anything.. just quits...

With compressor, it just gives a failed status....

All seem to either quit or fail around the same point... which I assume is at the point it reaches the "bad frame"


Does anyone have any insight on how to get these files to get files encoded al the way so I can burn them to DVD.

Any suggestions would be appreciated.

I'm on a dual 2 gig powerpc g5 mac.
2.5 gigs of ram
plenty of hardrive space
osx 10.4.11

Hmmm...have to run some experiments to narrow down the list of possibilities.

If you attempt to convert a certain file twice in a row, does it always fail at the same place? Or does the failure point move about? If the latter, does it move about randomly, or does it fail at about the same point?

Are the source files on your hard disk or on a disc? Either way, do these files play fine? Even if they don't hang during playback, do you notice any glitches or other anomalous behavior at the same point where the conversion fails? I know that you said "all the files work," but it's not clear if you were referring to the source files, or the bits that managed to convert.

Did you produce these source files yourself, or did they come from a third party?

You might try demuxing, then remuxing. Sometimes that does the trick.

Also, D-Vision3, among others, has an avi repair tool. If you have no joy with anything else, you might as well give it a shot and see what happens.

Hard disk

Either way, do these files play fine? Even if they don't hang during playback, do you notice any glitches or other anomalous behavior at the same point where the conversion fails?

I did not watch the source files all the way through to find that out, but now I have noticed that do DO GLITCH or FAIL when playing... also at the same point where the conversion fails.

Files came from third party. I did not produce the source files.

You might try demuxing, then remuxing. Sometimes that does the trick.

In my version of ffmpegx, it states "You can only demux .mpg, .vob or TiVo files."
Do you have a suggestion on what program I can use to demux and then remux Xvid avi files?

Running D-Vision 3 now - using the "fix" tool. I will update you on the outcome.



Additionally,
Since I couldn't get the files to encode to burn to DVD, I went out and bought a new DivX certified DVD player.
Using the same sources files that have the bad frames, I burned them all onto a DVD and the DVD player will play them.

However, there are some problems.
Once the DVD player reaches the bad frames, it get's super glitchy and the audio gets out of sync.
Then the video will speed up or slow down right before my eyes and then the audio and video will resync.

No matter how cool i think the auto resyncing may be.... I wiould still rather have it not happen...

Plus, some of the glitches still just completely freeze the playback on the DVD player and I have to shut it down.
I can't get past certain frames in certain files.

Thanks for the interest......
