• ffmpeg : "Error setting profile" ; how to keep original resolution odf odd sized videos ; getting Quicktime compatible output ; fixing pixel format

  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

• Crashing adobe premier cc pro when importing h264 mp4 file

  11 février 2017, par rpo

  I am screencasting with kazam in Ubuntu which is h264.

  To edit the video i tried to use vegas pro latest version. It only play the audio without any video.

  Then i tried to edit it with adobe premier 2017. Whenever i import the file(mp4) the premier pro just crash without any useful message.

  I installed quicktime for the codecs but no luck. I also converted the media with Format Factory(http://www.pcfreetime.com/) to MOV ... but premier just crash.

  How can i solve this ?

• ffmpeg - merge mp3 and mp4 (duration difference)

  8 décembre 2017, par dfionov

  I’m trying to merge mp4 and mp3 files with ffmpeg.
  mp4 duration - 9.800 sec, mp3 - 58.540 sec. So i using -shortest key.
  Code :

  ffmpeg -i video.mp4 -i audio.mp3 -c:v libx264 -c:a aac -strict experimental -shortest output.mp4

  After that i got output.mp4 with duration 9.846. Where is my error ? Why output video longer than source ? (9.846 sec and 9.800 sec).
