I have one .mp4 file with 1) video stream 2) audio stream (in that order, according to VLC codec information Ctrl+J)
After converting, the order of streams is switched: 1) audio stream 2) video stream

IS there a way to force the same order? Any problems I could run into. For starters, it seems Microsoft Explorer icons are shown differently (when audio comes first, they don't display in the right orientation)

It all depends on the timing of the tracks

Sorry.. depends what?
The order in which they show when I do Ctl+J. If I do the conversion with HandBrake, I keep seeing first the video track
Or are you talking about how Windows displays the icons?

Audio track (0) + video track (1) is pretty unusual order of tracks in a file. Perhaps it is possible to control the order of tracks in VLC muxer:

Change the id of an elementary stream (setid)
Set ES id:
--sout-setid-id=<integer> Elementary Stream ID
Specify an identifier integer for this elementary stream
--sout-setid-new-id=<integer>
New ES ID
Specify an new identifier integer for this elementary stream

?

I'm just using the convert option of the VLC windows app?

Are you saying there is a way of doing it perhaps form a command line? I was not even aware VLC had a command line. Can you explain me how would I do that?

I have just found those CLI options in vlc-help file. Perhaps it is possible to use them to control the id of particular streams in output when converting a file.

How do you use them within the graphic program?

"[v] Show more options" in Open Media dialog (Media > Convert/Save... or Stream... > [v] Show more options > Edit Options). You can edit stream output string in the final step in streaming wizard (Media > Stream...).

Sorry for the delay.. I finally got around to give it some tries

I add in this field ' :file-caching=300 :sout-setid-id=1 :sout-setid-new-id=0' and some variations

Still, audio stream is still the first one

Am I doing it wrong? Any ideas?

I was also curious so I also tried some combinations and I really could not make video to stay the first stream in a file. I could change the order of additional tracks in a file with multiple audio tracks. Then I observed that the video file was cut according to the shortest audio track (1 audio track several minutes shorter than the other one in the same file). I do not know whether there is a different/better situation in VLC 4.

Both of those issues seem like bugs, no?
Didn't know 4.0 was there. I tried 3.0.16 and still seeing the same problems.

VLC 4 nightly builds http://nightlies.videolan.org/

I tried 20210708-0426 and didn't allow me to open the input file

The problem is still present in Vlc 3.0.17.4.

Still no way to fix it in stable releases?
