• ffmbc : QuickTime to XDCAMHD422 MXF

  13 novembre 2018, par Ze'ev

  Trying to create an XDCAMHD422 MXF with video from a QuickTime and audio from a stereo WAV.

  Audio is pcm_s24le, 48000 Hz, 2 channels, s32

  But output is mixed :

  Stream #0.1(und): Audio: pcm_s16le, 48000 Hz, 1 channels, s16, 768 kb/s
  
  Stream #0.2(und): Audio: pcm_s24le, 48000 Hz, 1 channels, s32, 1152 kb/s

  And shows alert : Incompatible sample format 's32' for codec 'pcm_s16le', auto-selecting format 's16'

  (For XDCAM, it’s necessary to split stereo into dual mono.)

  Command :

  ffmbc -i "$v" -i "$a" -tff -timecode 07:00:00:00 \
  
  -map_audio_channel 1:0:0:0:1:0 \
  
  -map_audio_channel 1:0:1:0:2:0 \
  
  -acodec pcm_s24le -ar 48000 -ac 2 \
  
  -target xdcamhd422 -vtag xd5c -y  -t 1 "$o" \
  
  -acodec pcm_s24le -newaudio

  Output :

• ffmpeg get orientation inverted

  16 novembre 2018, par Faabass

  I getting the resolution for a video, but ffmpeg/ffprobe is getting inverted.. Always the biggest number is the width.

  I mean, it doesn’t matter if I’m getting the resolution of a vertical or horizontal video, I’m always getting for example 640x480 when it should be 480x640. Also I tried with the aspect ratio as 4:3 instead of 3:4

  ffprobe -v error -select_streams v:0 -show_entries stream=width,height -of csv=p=0 original.mp4

  So my question is how I can get the right resolution or at least the orientation I need to know if the video is horizontal or vertical.

  See full response :

  ffprobe -select_streams v:0 -show_entries stream=width,height -of csv=p=0 original.mp4

• How to remove everything but video and stereo audio stream from video with ffmpeg ?

  20 octobre 2019, par user3776738

  I’m trying to get a clean h264 video from a mkv file.With clean I mean that it has only a video stream plus stereo sound.
  The inputfile can have multiple channels and subtitles and other unknown stuff, which I don’t need.
  I’m using ffmpeg with this command :

   ffmpeg -i "input.mkv" -ac 2 -vf scale=trunc(oh*a/2)*2:480 -c:v libx264 "output.mp4"

  This should give me a 480p video with stereo sound,which I require.
  I tried multiple -map or dispositions commands with ffmpeg to remove the subtitles whithout any success.

  How can I remove everything but video and stereo stream with ffmpeg and get a 480p stereo sound video ?

  Edit :
  Output of ffmpeg - "input.mkv" -i "output.mp4" :

  ffmpeg -i "input.mkv" -i "output.mp4"
