FFmpeg to transfer from bad media
31 décembre 2017, par TheSavoI have an SDcard that has two videos recorded from an old phone. The media is bad and I have already run SpinRite and chkdsk, to fix the errors. The files still fail to copy completely.
I can play some portion of the files in VLC player. It plays about as far as File copy and TeraCopy before the copy job fails.
They and MP4 files. I would like to use ffmpeg to transfer the portion of the video that will play out. is-i
the best parameter ?ffmpeg -i H:\badfile.mp4 e:\portion.mp4

Convertion of mp3 file with ffmpeg results in a file with wrong length [duplicate]
16 avril 2018, par Arthur EfixtyThis question already has an answer here :
I wrote a simple script for Linux where I loop through the folder (containing only .mp3 files) and add an album art to every item.
Here is my code :
for file in ~/Desktop/Rise\ Against/*
do
ffmpeg -i "${file}" -i ~/Desktop/appeal\ to\ reason.jpeg -map 0:0 -map 1:0 -codec copy -id3v2_version 3 \-metadata:s:v title="Album cover" -metadata:s:v comment="Cover (front)" "${file%}";
doneIf I set the output filename to hardcoded value like
out.mp3
then it works fine. But I need these files to have the same name as existing and overwrite them.Running this script results in having all files edited as expected (the album art changed) but they all have a length of 3 seconds. In terminal I get this
[mp3 @ 0xc695e0] Audio packet of size 378219 (starting with 6B0855F2...) is invalid, writing it anyway.
Thanks in advance !
