Same Error With ffmpeg -f concat -safe 0 -i file.txt -c copy output.ts

file.txt is The List Of Files!

Your question is already answered here: https://stackoverflow.com/questions/7333232/how-to-concatenate-two-mp4-files-using-ffmpeg Don't do that: cat ./*.ts > all.ts — johnny b, Jul 28 '22 at 13:00
For kind of "sanity check", you may create synthetic video segments using shell command: `ffmpeg -f lavfi -i testsrc=size=192x108:rate=1:duration=100 -vcodec libx264 -g 10 -f segment -segment_time 10 -segment_list list.txt -segment_list_type ffconcat %03d.ts`. Then concatenate and convert to MP4: `ffmpeg -f concat -safe 0 -i list.txt -c copy output.mp4` — Rotem, Jul 28 '22 at 15:45

.ts file is not a plain text file, so you can’t see anything when open it with vim.
You can check the m3u8 file, if there is a license url, if yes, the .ts is encrypted. Also you can try to open the ts file with a media player, like VLC, it is playable if not encrypted.

Use this command:

ffmpeg -i downloaded.m3u8 -acodec copy -bsf:a aac_adtstoasc -vcodec copy Output.mp4

If u can get the m3u8 file by:

Trying to find it again through the url (if u have it) by replacing001.ts to index.m3u8
E.g.(https://stream.example.com/video/2021/example/index.m3u8)

Make your own m3u8 file:
An example of an m3u8 file:

#EXTM3U
#EXT-X-TARGETDURATION:13
#EXT-X-ALLOW-CACHE:YES
#EXT-X-PLAYLIST-TYPE:VOD
#EXT-X-VERSION:3
#EXT-X-MEDIA-SEQUENCE:1
#EXTINF:4.171,
seg-1-v1-a1.ts
#EXTINF:3.295,
seg-2-v1-a1.ts
#EXTINF:2.211,
seg-3-v1-a1.ts
#EXTINF:6.006,
seg-4-v1-a1.ts
...
#EXT-X-ENDLIST

The numbers after #EXTINF: is basically the length of the .ts file in seconds.
The numbers after EXT-X-TARGETDURATION specifies a maximum duration for the segments in the playlist. The actual duration specified by EXTINF may be less so change this value if necessary.
Thus, a very simple script can be written.

Move all of your .ts files to a folder
Make a .py file and try this:

import os
import subprocess
m3u8File = """#EXTM3U
#EXT-X-TARGETDURATION:13
#EXT-X-ALLOW-CACHE:YES
#EXT-X-PLAYLIST-TYPE:VOD
#EXT-X-VERSION:3
#EXT-X-MEDIA-SEQUENCE:1
"""
tsPath = "./tsFiles"
tsFiles = next(os.walk(tsPath), (None, None, []))[2]
for ts in tsFiles:
    length = subprocess.check_output(['ffprobe', '-i', ts, '-show_entries', 'format=duration', '-v', 'quiet', '-of', 'csv="p=0"'])
    m3u8File += "#EXTINF:"+length+",\n"
    m3u8File += ts + "\n"
m3u8File += "#EXT-X-ENDLIST"
with open("output.m3u8",'wb') as output:
    output.write(m3u8File)
    output.close()

I haven't tested the code above, but I trust that you will be able to debug it yourself, also I've never used subprocess.checkOutput() before so I'm not sure if it will run properly. But anyway, make sure you have ffmpeg binary folder added to Path environmental variable, otherwise the ffprobe command won't work. ffprobe should come with ffmpeg. Let me know if it works along with the error message if it doesn't.

Please Accept this answer if it helped you. Thanks!
