the cliped .360 file has different stream order, how to reorder them

[CanCanZeng]

Hi, I don't know if it is suitable to ask question here, but any suggestion is appreciated.
I find that the cliped .360 file from GoPro Player has different stream order, how can I reorder it as normal .360 file?

the output of ffmpeg -i a.360 of normal .360 file is

Stream #0:0(eng): Video: hevc (Main) (hvc1 / 0x31637668), yuvj420p(pc, bt709), 4096x1344 [SAR 1:1 DAR 64:21], 30036 kb/s, 25 fps, 25 tbr, 90k tbn, 25 tbc (default)

if reorder the stream of cliped file is rather hard, is it possible to clip the .360 file using ffmpeg? (reserve the cliped meta info)

[dnewman-gpsw]

Not sure why the order matters.

You can trim with ffmpeg, but it will lose the header metadata, which can be restored with udtacopy (https://github.com/gopro/labs/blob/master/docs/control/chapters/bin/udtacopy.zip)

e.g.

ffmpeg -i D:\48HPF-Sync\Cam-Beach\GS010003.360 -map 0:0 -map 0:1 -map 0:2 -map 0:3 -map 0:4 -c copy -ss 00:00:05 -t 00:00:10 D:\48HPF-Sync\Cam-Beach\GS010003.trim.MOV
udtacopy D:\48HPF-Sync\Cam-Beach\GS010003.360 D:\48HPF-Sync\Cam-Beach\GS010003.trim.MOV
rename D:\48HPF-Sync\Cam-Beach\GS010003.trim.MOV D:\48HPF-Sync\Cam-Beach\GS010003.trim.360

Hi @dnewman-gpsw , thanks for your help!
I need the order to be the same because I use the following code to concat multi-segments

ffmpeg -y -f concat -safe 0 -i list.txt -c copy -map 0:0 -map 0:3 -an channel_0.mp4
ffmpeg -y -f concat -safe 0 -i list.txt -c copy -map 0:5 -map 0:3 -an channel_1.mp4

so I need the first video stream in channel 0 and second video stream in channel 5.

I tried your method, but the output *.trim.360 has different channels than the original 360 file. I find that the first step using ffmpeg to clip the videos cause lose of streams: the original file has 6 channels but the *.trim.MOV file has only 4 channels.
