ffmpeg not converting entire file

overhead: 0.009689%As you can see, the input file is 17:35.95, but ffmpeg is only converting 10:54.19 of it. Does anyone know what’s going on here ?
edit : I tried it with a different tak file and got the same result. Only 27 minutes of a 50 minute tak was converted to flac. I get the exact same output file times when converting to wav, so I’m guessing it must either be something with the tak files I have, or with ffmpeg’s tak decoder.

Prevent output in error log when ffmpeg job is initiated via PHP's shell_exec()
19 janvier 2016, par JakeI’m getting the entire output of the ffmpeg command printed to my server’s error.log — but as far as I can tell, the jobs complete successfully with no error.
Is there any way to suppress the output ? I have seen people append stuff like
>/dev/null 2>/dev/null &to their command, however that forces the command to return immediately and the job runs in the background. Unfortunately, I need the job to run in the foreground, because I need to do stuff with the output once the job is done.Here’s the command I am running...
shell_exec('ffmpeg -i input.mp4 -f mp4 -c:v libx264 -preset slow -crf 24 -s 1280x720 -c:a libfdk_aac -profile:a aac_he -ar 22050 -b:a 64k -movflags +faststart output-1280x720.mp4');Here’s the output I am seeing...
