• FFMpeg Combine wav and avi to mp4

  15 avril 2016, par krisph

  I am trying to combine a wav file and a avi in to a single mp4.

  I can do this with the following via php :

                      $command = 'start /B convertvid\bin\ffmpeg -nostdin -i Temp\\temp.avi -i Temp\\temp.wav -y -filter:v scale=1920:-1 -c:v libx264 -preset ultrafast -movflags faststart -crf 31 -c:a libvo_aacenc -b:a 64k Temp\\output.mp4';

  However it takes an age to complete and i need to speed it up, i was just wondering is there anything that could be done to optimize the commands to make it faster ?

  I have tried the command using just the command line and it still takes ages...

  C:\inetpub\wwwroot\Update\>convertvid\bin\ffmpeg -i Temp\temp.
  
  avi -i Temp\temp.wav -y  -c:v libx264 -preset ultrafast -movflags faststart -crf
  
   31 -c:a libvo_aacenc -b:a 64k Temp\testhis.mp4

• Encode videos to send with WhatsApp

  28 avril 2017, par piegames

  I have a series of PNG images of a video I rendered and now I want so send it via WhatsApp. I used to encode my videos with the command from this answer, but apparently the videos can only be played from WhatsApp web ; on the phone I still get an error message. How do I convert them so that they can also be played on phone ?

  Command used :

  %PATH_TO_FFMPEG%\ffmpeg.exe -i paint\out%04d.png -c:v libx264 -c:a aac ./videos/out7.mp4

• Problem recording camera stream through ffmpeg - Inappropriate ioctl for device

  16 septembre 2021, par Otter_warrior

  I'm trying to record a camera stream through ffmpeg, but I'm struggling to understand how to write a correct recording command.

  


  This is the camera format according to v4l2

  


  $ v4l2-ctl -d 1 --list-formats-ext
ioctl: VIDIOC_ENUM_FMT
    Index       : 0
    Type        : Video Capture
    Pixel Format: 'RG12'
    Name        : 12-bit Bayer RGRG/GBGB
        Size: Discrete 1920x1080
            Interval: Discrete 0.033s (30.000 fps)


  


  And this is what I tried so far

  


  ffmpeg -framerate 30 -video_size 1920x1080 -i /dev/video0 output.mkv


  


  which would return this and an empty output file

  


  $ ffmpeg -f v4l2 -framerate 30 -video_size 1920x1080 -i /dev/video0 output.mkv

  I'm new to ffmpeg so I can't determine which settings or properties could help me with this format, or if this format is even supported at all. Any help would be greatly appreciated.

  


  Note : I am working on a Jetson board, but gstreamer or nvgstcapture are not an option
