Elementary Stream Muxer - File is not a recognised video file

I have a .mp4 file which in most circumstances VideoReDo seems to handle without a problem. What I want to do is save it as elementary streams, do something to the audio in another application, and then re-multiplex the streams. Unfortunately VideoReDo won't let me.

Even ignoring any work I might want to do on the audio, if I just save the .mp4 as elementary streams and then immediately try to re-multiplex them, having done nothing to them in the meantime, the Elementary Stream Muxer reports that the .h264 file is "not a recognised video file".

Any suggestions for what I should look at or change to resolve this?

I'm thinking that there is perhaps a defect in the video that VRD catches once it
start to mux the two files back together.
Taking a file apart should be much simpler then putting one back together.

Betting that if you recode the file in VRD that it would then mux with no problem.

Another possible problem just popped into my head...
You can find video files with a video type and audio type that VRD does not support.
It may be able to take the file apart but it will not put them back together.

Thanks for the info, though I'm not that much the wiser as to the specific issue in this case - particularly what to look out for in the future.

The only reason I was using VRD was to avoid recoding the video, I've various applications which can take the video from the original file, the updated sound track and put them together with a re-encode,

You can try and run your file through "QuickStream Fix" in VRD. (in Tools)
Look at the window of information that pops up after the QSF and see if it list any problems.

That's odd. If VRD can open the MP4 then it should be able to open the .h264 ES stream from it. Try going to Options-> Stream Parameters and increasing the MBytes to scan option and see if that makes any difference.

I ran into this just now (not a recognized video file) and while trying several different programs to preconvert I accidentally copied the file from the external drive to the PC desktop. TV suite opened the desktop copy but when I moved the copy to the external it wouldn't open it any more. Then I moved it back to desktop and it worked again. Don't know why this should be so but at least I can work with the file now

That sounds weird. What's type of physical media is the external drive? Can we edit fully muxed video from the external drive?

Is the ES file on a local hard drive? If not, try copying it to the local drive and mux from there.

Otherwise, do you want to upload the ES files to us?

Is the problem just this one file or all files?

Finally, I'm curious what kind of audio processing are you doing?

I am not familiar with muxing.

Occasionally I've had problems with other files that TV Suite would not call up so maybe this discovery will solve some of that, however it's usually a problem with TV suite not liking the audio

This particular mp4 that was the problem I downloaded from a pay site on the internet. The same thing happened with DVD Fab, would not open this file from the external drive (Seagate 2TB) but opened it when I moved it to the C drive.

I tested some other mp4 files from the external drive on TV Suite and it opened them all no problem

good luck to us all!

I do that every day, I use Yamb to re-multiplex the streams. It's free, simple, and very quick. Go to http://yamb.unite-video.com/download.html and download "Yamb-2.1.0.0 beta 2 with installer ".
