  30 août 2022, par bon ho

  I'm making music bot with discord.py and using heroku. bot is playing music my localhost but heroku host is not playing music.

  


  I found what cause a bug.
It working nicely in heroku-20, but not working in heroku-22 stack.

  


  How can I use heroku-22 stack without error ?
What can I do ?

  


  I'm sorry my english is bad.

  


  my code :

• how can I convert a stack of PNGs with transparency to a video playable with Keynote

  29 juin 2022, par John Smith

  I used to convert a stack of PNGs with alpha transparency using ffmpeg :

  


  ffmpeg -i frame_%03d.png -vcodec png output.mov


  


  I have an old mov where this worked. Now I tried to do that again a while later (on an M1 Mac now). Now it doesn't work anymore. Here are the file properties :

  


  





  


  


  


  


  


  



  


  


  


  


  


  


  


  


  


  


  


  


  


  


  


  


  


  


  


  


  


  


  


  


  


  property	old movie (works)	new movie (does not work)
  resolution	378 × 378	1600 × 1000
  codec	Apple ProRes 4444	PNG
  alpha channel	yes	?
  color profile	SD (6-1-6)	?
  software	Lavf57.41.100	Lavf59.16.100

  


  


  The ? shows that I cannot open the new file in Quicktime, nor import it in Keynote. Any idea how I can use ffmpeg to convert my image stack to a file with transparency that works in Keynote / Quicktime ?

  


• [MPV][FFMPEG] stack two videos to play them synchronously without re-encoding, but with a rotation (from metadata) applied to one of them

  10 juin 2022, par publicIDI

  I have 3 videos with the same resolution (1920x1080), but one of them has the rotation property set in the metadata while the two others are reencoded in the correct orientation.

  


  I would like to stack them horizontally to compare their quality without re-encoding.
I know how to dynamically stack and display them with MPV, but not when one of them has a rotation metadata property :

  


  Two videos in parallel

  


  mpv --lavfi-complex="[vid1][vid2]hstack[vo];[aid1][aid2]amix[ao]" "v1_metadata.mp4" --external-file="v2.mp4"


  


  Three videos in parallel

  


  mpv --lavfi-complex="[vid1][vid2][vid3]hstack=inputs=3[vo];[aid1][aid2][aid3]amix=inputs=3[ao]" "v1_metadata.mp4" --external-files="v2.mp4;v3.mp4"


  


  Precisions

  


  v1_metadata.mp4 : rotation in the metadata

  


  

  


  v2.mp4, v3.mp4 : no metadata rotation

  


  

  


  How can I "apply" the rotation to the first video (v1_metadata.mp4) in order to display it stacked with the others ?

  


  Thanks,
