Description
Summary of the enhancement request: FFMPEG is currently able to create multiple files by splitting an existing file using the segment option. However there is no option to be able to join the segments back into a single file.
Perhaps there can be a way (like concat for MPEGTS files) to be able to specify multiple file inputs and join the video and audio tracks to create a single output file.

For example, if I run the following command (attaching 3 sample files used)
ffmpeg -i "concat:test1.wtv|test2.wtv|test3.wtv" -c copy test.wtv
The output file (test.wtv) only contains the first file (test1.wtv) and not the remaining two.

This strategy only seems to work if the inputs files are mpegts files.

Okay thanks, yes I tried that it works now.
I have a request, it was a HUGE problem escaping ALL special characters INCLUDING spaces. Can the text file format be adjust to accept the ENTIRE file path within QUOTES and NO escaping of characters?
comment:5 follow-up: ↓ 6 Changed 5 months ago by ramitbhalla
Alternative can the old Pipe format (like what I've used above) be retained? (only escaping the quotes are required).
comment:6 in reply to: ↑ 5 Changed 5 months ago by cehoyos
Replying to ramitbhalla:
Alternative can the old Pipe format (like what I've used above) be retained?
What makes you think the concat protocol (if that is what you mean) will not be retained?
comment:7 Changed 5 months ago by ramitbhalla
What I was suggesting is that the concat demuxed (-f concat if I get it correctly) should also use the same format as the concat protocol for inputs file name rather than a text file, it makes the command line management a whole lot easier.
i.e.
-f concat -i "\"C:\Test Directory\Test1.wtv\"|"C:\Test Directory\Test2.wtv\""
Note: See
TracTickets for help on using
tickets.
Could you explain (= show an example command line including complete, uncut console output) why this is not possible with the concat protocol, the concat filter or the concat demuxer?
