recompile ffmpeg with libmp3lame
1 answer
I use this command on ffmpeg :
/usr/local/bin/ffmpeg -ss 40 -t 40 -i mymusic.mp3 -ab 15 voice.mp3 2>&1
but I see this error :
Automatic encoder selection failed for output stream #0:0. Default encoder for format mp3 (codec png) is probably disabled. Please choose an encoder manually. Error selecting an encoder for stream 0:0
Also lamemp3 installed and enabled, how can I fix it ?
this is complete output :

How can I skip an image error when trimming an mp3 with ffmpeg
29 septembre 2016, par John PollardI am running the following command to get cut a 30 second section of the file
ffmpeg -i 'river.mp3' -ss 30 -t 30 -acodec libmp3lame -b:a 128k 'audio_trimmed.mp3'
but I am getting a "Invalid PNG signature" error. Is there a way to skip the image since I don’t need it and have the command run successfully ?
