  • ffmpeg : "Error setting profile"

    26 février 2017, par P. Reid

    I’ve been having trouble using ffmpeg to compress videos to something readable by quicktime. My goal in the end is to have a simple command that I can use to compress high bitrate videos (ie screencaptures) to something more reasonable to be able to share them with people.

    I want to use a command I found here as a starting point :

    ffmpeg -i input-file.avi -codec:v libx264 -profile: high -preset slow -b:v 500k -maxrate 500k -bufsize 1000k -vf scale=-1:480 -threads 0 -codec:a libfdk_aac -b:a 128k output_file.mp4

    Unfortunately I get this error :

    [libx264 @ 0x7f92ab81c200] Error setting profile high.
    
[libx264 @ 0x7f92ab81c200] Possible profiles: baseline main high high10 high422 high444
    
Stream mapping:
    
  Stream #0:0 -> #0:0 (rawvideo (native) -> h264 (libx264))
    
Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

    If I take out the -profile: high the command functions but the output still doesn’t open in quicktime (it does in VLC). I can’t find the keyword -profile on the ffmpeg man page : https://ffmpeg.org/ffmpeg.html so I don’t know if this is important or what to do about it.

    Does anyone know what might be causing my problem ? What should I do to try and debug this problem ? I would describe myself as inexperienced so sorry if I’m missing something obvious.

    Thanks in advance for your help,
    Peter
