Why does my script return 0 when it fails ? Bash, Whisper, ffmpeg
30 avril 2024, par d-bI have a
bashscript that executeswhisperon all sound files in a directory. Whisper usesffmpegto decode sound files to a format it can handle. One of the files in the directory was corrupt and caused ffmpeg to fail. The first time I executed my script it returned1when it hit that file but when I try to reproduce the error it always returns0.

Here is the log from the first run when 1 was returned :

soundfile1.opus: Invalid data found when processing input

% echo $?
0


When I try to reproduce the behaviour I have both tried to execute the script as well as just running the actual line of code from the command prompt. The actual script looks like this :


if whisper "$file" >> "${directory}/../${transdir}/${name}.txt"; then
 whispersuccess=$?
 echo "exit code $whispersuccess"
else
 whispersuccess=$?
 echo "exit code: $whispersuccess"


I want it to return ¬0 when something like this happens. How do I achieve this ?

FFmpeg stuck on frame 0 during time-lapse conversion with `-ss` start time
2 janvier 2021, par rgovI have a long video that I'd like to speed up into a time-lapse. Following the FFmpeg wiki, I came up with this incantation :



ffmpeg -i IMG_0238.MOV -r 60 -ss 00:04:41 -filter:v "setpts=PTS/60.0" -an output.mp4



It should clip off the first few minutes, then create a new 60fps video file at 60x the speed.



Although it spins all my CPU cores up to 100%, the status bar simply shows
frame= 0 fps=0.0 q=0.0 size= 0kB time=00:00:00.00 bitrate=N/A speed= 0xand never progresses.


The problem seems related to the
-ss 00:04:41flag, which specifies the start time ; I want to drop the first 4 minutes 41 seconds of source video. When I omit this option, the video conversion succeeds.


Full log follows.
