Accuracy of timer in FFMPEG

Post by faiz321 »

Dear All,
I am using the below command to capture audio stream in while (1) loop to create audio files of 1 hr each.

ffmpeg -i x.sdp -q:a 0 -sample_rate 8000 -acodec ac3 -loglevel panic -t 3600 -f wav out

It is observed that the duration of generated output file is decreasing to 45 min after 3 days of continuous running, the duration reduces monotonically after 3 days to 0 sec.

Please provide any possible reasons for such behavior.


Faiz Ahmed.
