Stream 0: audio first, then Stream 1: video PROBLEMS

[andwan0]

I have a movie, audio sync is fine if I play in SMPlayer.

However, when I watch in VLC, the audio is way out of sync by minutes - if I seek to a future time, etc.

When I look at the codec media info, it shows that the first Stream 0 is the audio. Normally, all my other movies, Stream 0 is the Video.


Is this a known problem for VLC?

No.

You can try to remap (swap) audio and video track:

@ffmpeg -i "%1" -map 0:1 -map 0:0 -c copy -f matroska "%~n1_swap.mkv"

Or swap the streams and remux with MKVToolnixGUI. It'll open the common containers (AVI, MP4 etc) and remux as MKV.

If you using Windows just create with simple text editor new file, name it somehow, copy above line, save, after this change extension to bat or cmd, after all you will have script file, drag and drop your video on this file - after few moments you will get new file with similar name - ffmpeg can be downloaded from link provided by VideoHelp - all you need is to have ffmpeg.exe in same folder where your newly created script is located.
