MMT Mux Problem

[SCB]

Whenever I try to mux an audio and video track in MMT it stops after only muxing a couple minutes. The error says that there are too many frame drops. I'm new to MMT; WTF?

What 2 file types are you trying to MUX ? What are the 3 letters after the "." meaning .MP2 or .MV2 etc ...

squeed is right, you did not give us much to work on. Sounds like too high of bit rate. Try the "user" check box.

I'm trying to mux .mp2 audio and .m1v video.

I tried checking the user box and I got the same results. I don't think the bit rate is a problem. The video is at standard VCD spec. and I encoded the audio with MMT. Here's my terminal output.

I think that the .M1V file needs to be an encoded mpeg-1 file. If you have a .M1V it leads me to believe that you just demuxed a VOB and are trying to mux it without encoding the MPEG to .MPG-1 for VCD.

Where did the .M1V file come from ?

I think that MUX needs to have the video file be a .MPV file or an encoded MPEG-1 file to work.

If I recall, 48khz sample rate audio is not supported by the VCD format.
