[FFmpeg-user] Intermittent error when segment files from concat

[Tung Tran]

Hello

I am trying to concat the segments files from previous transcoding (using
-ss option) and fragment it for hls, but sometime I got this error

*Could not write header for output file #0 (incorrect codec parameters ?):
Invalid argumentStream mapping:*

but sometime it worked just fine, same command,
Please give me some hits how to make it more stable.

Thank you very much


Below is my command

/opt/ffmpeg/ffmpeg -i
 'concat:/farm/files/out/587d0488bb4262d21c8b4577/587d0488bb4262d21c8b4577_part0.3696.kbps.ts|/farm/files/out/587d0488bb4262d21c8b4577/587d0488bb4262d21c8b4577_part1.3696.kbps.ts|/farm/files/out/587d0488bb4262d21c8b4577/587d0488bb4262d21c8b4577_part2.3696.kbps.ts|/farm/files/out/587d0488bb4262d21c8b4577/587d0488bb4262d21c8b4577_part3.3696.kbps.ts'
