Audio and Video not combining

[adeleander]

I had to reset my system and have re installed ffmpegx.

But now when I convert to H264 its writing the audio and video as seperate files.

It didnt do this before and am even using the same file that I converted before and it worked fine.

Anyone know why its doing this and how to stop it?

Thanks

[adeleander]

Interesting it works fine if I just convert to MP4, but H264 just doesnt seem to work anymore, no matter what I do I always get a seperate audio and video track.
If converted to MP4 it seems to work fine in Apple TV, so guess Im stuck with the old video format!

Patience. When the ffmpegX Progress shows 100% it is not finished. Two files are created, one for video and one for audio. You have to wait for thee to be merged; if you try to run one of these before the files are merged they will stay separate. Just wiat until ffmpegX Progress shows Finished. I hope this solves your problem.

sorry to bring up an old topic, but how long would it take to finish? I have let it for a long time after is says 100% but it never finishes. The file was a 720p x264 mp4, 25mins in length.

I've seen it take as long as five hours if the source video was goofy in some manner. At that point I abandon ffmpegX and move to MPEG Streamclip.

Hi, I just re encoded my x264 25 min file. It took about 1 hour to go from 100% to finished but there are still two seperate files. audio and video...one other file (a x264 mkv with ac3 audio) was giving me the same problem but every other file works ok so far. I'm going to try out mpegstreamclip

Here is my log of the 720p x264(a 720p xvid source with ac3)

Also the resulting file should be about 1.1 gb's but the two files total about 5.3 gb's with the video file being 5gb's.

I haven't run into that particular error before, but the message "non monotone timestamp" suggests where the problem might lie. Is the source video from a live source that you cobbled together? What the error message seems to be saying is that there are two successive timestamps with the same value, instead of incrementing. Perhaps that's where it's getting hung up. You may need to fix that in the source before you can proceed smoothly. Or it may have nothing to do with your problem at all. How's that for a definite maybe?

[fatcat23]

I captured a 720p source on my HD Free to Air box(external usb hd) as ts stream then put into videoredo and outputed edited 720p ts stream. then into handbrake on pc as 720p xvid with ac3 audio. But Im know going to do x264 with aac 2ch in mp4. But i had already deleted my ts file. So I will be using mpegstreamclip for the rest of the ts streams(i have tried and it works good) but i'm stuck with a couple of 720p xvid files. I will try them in mpegstreamclip also, it should work.

I have no idea what that error message is about. I used qt pro to output that same xvid file to h264 and it worked really good. Thanks for the help tho.

[tomlee59]

Judging from the fact that I'll get sync errors much less frequently if I decode with QT, there are differences in how time is evaluated. So, if the source clip has some weirdness, it may provoke an error with one particular program, but not necessarily the same in QT. So, functioning in QT is not necessarily a definite sign that the source file is fine; it could be that QT is simply more tolerant.

If there's a way to demux the (possibly) troublesome source and then remux it, that sometimes takes care of a multitude of sins. In your case, with an xvid source, you might want to have avidemux take a whack at it, or something similar. Maybe that will solve your problem.

Good luck!
