• zoompan - set output image size to input width x height

  15 septembre 2020, par Sarmad S.

  I have the following command :

  


  [0]zoompan=z='min(zoom+0.0015,1.5)':x='iw/2-(iw/zoom/2)':y='ih/2-(ih/zoom/2)':d=125:s=1600x1066[z0];


  


  But I want the value of s to be the same as input width x height. I have tried s='in_w:in_h' and other similar combinations, but it didn't work.

  


• Diagonal split to show two positions of the same video frame. Landscape input, portrait output

  23 septembre 2020, par ajomajo

  I have a 16:9 video with two faces talking to eachother. I want to make a portrait video output (for smartphones viewport) where I show both faces in the same frame, split diagonally. Is this possible ? Like this : from [o o] to [%]

  


  I have used a filter .script-file earlier to fit one face into the frame, but now I'd like to fit both faces from the same scene, and preferably diagonally.

  


  The viewer will be able to see the two faces having a dialogue in a portrait aspect ratio, no matter how far away they are from eachother in the original landscape aspect ratio.

  


• ffmpeg - how to pass all streams audio/tmcd, etc from input->output unchanged

  22 avril 2021, par QRrabbit

  Please help me, with hopefully specific ffmpeg arguments to include in my video encoding.

  


  My work is only related to video stream, so this is the only one I'm changing.
I receive a .mov file(s) that have already been pre-compiled for a specific broadcaster, some of those selfcontained videos have 4 streams (1 video, 2 audio, and some other timecode stream). Others have up to 17 streams : 1-video, 15-audio streams and the final one is unsupported tmcd.

  


  My process pipeline includes only re-encoding/re-processing video stream, and everything else I need to pass along to the output file - all other streams without any changes or alterations.

  


  During this step of encoding, I insert icon.png into position 5:21 from sec 2-3, from 4-5, and from 6-8. To achieve this, I use map option, so my encoding string looks like this :

  


  ffmpeg -i in.mov -i icon.png -i icon.png -i icon.png
    -filter_complex "  [0][1]overlay=5:21:enable='between(t,2,3)'[v1];
                      [v1][2]overlay=5:21:enable='between(t,4,5)'[v2];
                      [v2][3]overlay=5:21:enable='between(t,6,8)'[v3]" -map '[v3]' -map 0:a
    -c:v dvvideo -pix_fmt yuv422p -b:v 115084915 -maxrate 115084915 -minrate 115084915 -r 29.97 -top 1 -color_primaries bt709 -color_trc bt709 -colorspace bt709 -vtag dvh6
    -c:a copy -c:s copy -y out.mov


  


  The problem is that the out.mov only shows with 2 streams instead of 17 (1-video, and 2-audio). All other 15 streams are truncated completely.
Reading some other stackoverflow posts I found a way to transfer all other streams, is by using -map 0 :

  


  But as I tried adding -map 0 on my last line :

  


      ...
    -map 0 -c:a copy -c:s copy -y out.mov


  


  but this doubles the number of streams from 17 to 34 - also double in output file size.
If I remove map '[v3]' -map 0:a from my original encoding string and only include -map 0, I get correct number of streams, but, of course icon.png is not getting inserted at the right time. What should I do ?

  


  If there's a way to re-map my -filter_complex to overlay images without using this -map option ? Or, be specific at what each -map referring to ?

  


  If not, what other arguments/parameters can I use, if such option even exists, to copy all streams, subs and all other audio, potentially some other signal for audio impairment, if such exists.

  


  Please help, so I can finally wrap my output and submit my work.
