• Any Faster alternative to FFplay

  29 août 2020, par WiNtEr_IcE

  I am trying to use this concoction of commands to create active noise cancellation. The thing that slows it down is the ffplay, I have tried all the different flags but there is still about a 1/2 second delay

  


  rec -c 1 -t wav - | ffmpeg -i pipe:0  -af "aeval='-val(ch)':c=same" -f wav - | ffplay -fflags nobuffer -flags low_delay  -


  


  Is there any solution to this or is it something that is inherently slow and no alternative. I know it is not the filter that slows it down because I have done some testing and filtered a 5 minute song in about 3 seconds. I would love to get any possible help.

• Convert audio to video ffmpeg with a gif as the background loop the and keep the audio length

  21 janvier 2018, par akiva

  I used this to combine a JPG and MP3 into a video :

  ffmpeg -loop 1 -i 1.jpg -i song.mp3 -strict -2 -c:v libx264 -tune stillimage -c:a aac -b:a 192k -pix_fmt yuv420p -shortest out.mp4

  I’m trying to change the .jpg to a .gif, but the gif should loop to the MP3 length

• My music doesn't play correctly and other problems - Discord.py

  24 mars 2021, par Diacono

  So, I'm triying to let my bot play songs directly from the url (without downloading them like the song.mp3 method) but I'm having a hard time. The bot plays only 1 song and when I try to play another song it doesn't play it.
I'm also getting 2 errors : video_link is not defined and self is not defined.
Also when I try to play live music like "lofi hip hop radio - beats to relax/study to" nothing happens.
Can you help me please ???
