  • How can I skip an image error when trimming an mp3 with ffmpeg

    29 septembre 2016, par John Pollard

    I 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 ?

  • Automatic encoder selection failed for output stream #0:0 [duplicate]

    2 octobre 2016, par mgt1234

    This question already has an answer here :

    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 ?
