Hello any brother can help me solve this. when i run, i cant extract the full subtitle. it display this.
invalid concatenated file detected - using bitrate for duration
Estimating duration from bitrate, this may be inaccurate
Header missing

Messages before "header missing" are not "real" errors. They are more like warnings.
"Header missing" is the error, but I can't tell you why.

The lastest faster whisper cut my audio into half. Not letting me convert the whole audio into subtitle. I change to turbo but it is not that accurate. I try to figure out the problem for the cutting audio into half. Maybe is the audio problem or maybe the system not support with that. Anyway thankss for the explanation brother.

I think the problem is the encoding of your audio files. "invalid concatenated file detected" is because your audio files have differents bitrates of encoding or differents codecs encoding... It's seems to be a bug with ffmppeg.
Try to re-encoding (or convert) your audio files with VLC or other software.
