Hello,
the following script will be used :
#!/bin/bash
while IFS= read -r -d $'\0' video
do
filename=$(basename -- "$video")
filename="${filename%.*}"
ffmpeg -y -i "$video" -vcodec libx264 -crf 51 -preset ultrafast
-acodec copy -f mp4 -movflags frag_keyframe+empty_moov+delay_moov pipe:1
>/dev/null 2>"${filename}.txt" </dev/null
TxtFileName="${filename}.txt"
done < <(find -iregex ".*\.\(mp4\|mkv\|m2ts\|ts\)" -print0)
grep -i -n 'error\|duplicate\|failure\|missing\|POCs\|corrupt'
"${TxtFileName}"
echo "Ready"
read pause
Output :

My question, are there more then the given error list :
grep -i -n 'error\|duplicate\|failure\|missing\|POCs\|corrupt'
"${TxtFileName}"
to find corrupted frames ?
Or is it possible, that I will miss some error indications ?
Regards
Gloster
