  • ffmpeg mp4 to mp3 conversion error 'no such file'

    11 juin 2016, par Thomas R.

    I’m using ffmpeg to convert mp4’s to mp3’s, about 124 videos total, and I’m using python to iterate through the files they’re in and executing a version of ffmpeg -i pathtovideo/video.mp4 pathtoaudio/audio.mp3 to convert them.

    When I use this command on its own in terminal, it converts just fine, but calling from the python script (using os) it says pathtoaudio/audio.mp3: No such file or directory but of course there isn’t, I’m asking the computer to generate this file. Any ideas for what might be going wrong or how to fix ?

  • FFmpeg CPU utilization

    9 août 2013, par user2565986

    I have a server running Scientific Linux. I'm trying to convert a large amount of videos and want to maximize cpu usage. My ffmpeg version is git-2013-08-06-a68b6ec.

    ffmpeg -y -i "$i" -c:v libx264 -preset fast -b:v "$VID_BIT" -threads 0 -c:a libfdk_aac -b:a "$AUD_BIT" -f mp4 /"$OUT_DIR"/"$MD5"

    I'm not sure why user usage is at 0% and the niced usage is all I see, but either way I'm looking for a way to get the usage up to 100%. Is there anyway to bolster the usage or is this the best I'm gonna get ?
