• FFmpeg conversion to Photo-JPEG is blocky [duplicate]

  26 mai 2017, par Richard210363

  • ffmpeg generate higher quality images for MJPEG encoding

  I am converting .mp4 files to .mov with the Photo-JPEG codec to use in After Effects to reduce render times.

  I have looked up the FFmpeg commands to do this and come up with :

  ffmpeg -i tower-bridge.mp4 -an -pix_fmt yuvj420p -vcodec mjpeg -f mov -y tower-bridge.mov 

  This works but when I look at the output video it is quite blocky ; like a mosaic.

  During the conversion I get this message :

  [swscaler @ 0000000008c97fe0] deprecated pixel format used, make sure you did set range correctly

  Research on-line suggests I can ignore this message.

  What can I do to improve the output quality ?

• heroku discord.py bot doesn't play music

  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.
