How to run ffmpeg in a loop and test it for error ?
24 novembre 2016, par David CabreraI have stuttering, seeking, and general playback issues when playing large mkv files through my Plex Media Server setup. I have been looking around for a way to automate scheduled tasks to move everything to mp4. The objective is :
Copy mkv files into mp4 preserving subtitles of every kind. Put the new file in the same subdir, and delete previous mkv version if conversion went successful.
When I tried to run ffmpeg on a loop, I run into the problem described here :
http://unix.stackexchange.com/questions/36310/strange-errors-when-using-ffmpeg-in-a-loop
This is my first adventure on shell scripting and I am pretty much stumbling around and trying to understand the syntax and philosophy of it. What I understand is that they use a file descriptor to redirect ffmpeg output to /dev/null.
The problem with that solution is that I would need to check ffmpeg output for errors to decide whether to delete the previous file or not. Furthermore, there is a common error when converting from picture based subtitles streams, which I circumvent by using a script I found (http://www.computernerdfromhell.com/blog/automatically-extract-subtitles-from-mkv/) to work after some modifications to my needs.
After much frustration I ended modifying the script so much that it does not serve to its purpose. It does not check for errors. Anyways, I will post it here. Mind you that this is my first shell script ever, and almost everything is confusing about it. The problem with this, is that I had to ditch my error checking and I am eliminating files that errored when converting. Losing the original without a valid copy.

echo "#### Extracting subtitles ###"'\n''\n'
mkvmerge -i "$line" | grep 'subtitles' | while read subline
do
# Grep the number of the subtitle track
tracknumber=`echo $subline | egrep -o "[0-9]{1,2}" | head -1`
# Get base name for subtitle
subtitlename=${line%.*}
# Extract the track to a .tmp file
mkvextract tracks "$line" $tracknumber:"$subtitlename.$tracknumber.srt" < /dev/null
chmod g+rw "$subtitlename.$tracknumber"* < /dev/null
done
rm -frv "$line" < /dev/null
echo "Finished: $(date +"%Y%m%d-%H%M%S")"
done
echo '\n'"<===--- DONE with folder: '$FOLDER'"$'\n'$'\n' >> $LOGFILE
done
exit 0So, basically, the idea is : run ffmpeg on a loop for all mkv under a directory and subdirectories (I was using find). Check it for all possible errors. If errors, try again without subtitles and extract the subtitles using mkvextract, else everything went ok, and delete the previous file.
