I'm trying to lossless concatenate two MP4 files using FFMPEG. The files
have 1 video stream, 2 audio streams, subtitle stream and chapter markers.
Here is the info for one file (the two files have identical stream
configurations).

I have tried the following simple concatenation command which worked
perfectly only it outputs just the video and the first audio stream.
Video list file:
# videos.txt
file 'BOTRK1.mp4'
file 'BOTRK2.mp4'
and the FFMPEG command
ffmpeg -f concat -i videos.txt -c copy output.mp4
Is it possible to concatenate the 2 5-stream videos losslessly? I saw
commands using video filters but I don't think they're lossless. I
think I'm just missing a couple switches to allow copying of the missing
streams but I have no clue what they are.
This is the output from my concatenation that only output video and 1 audio.
