  I’m running Windows on a MacBook Pro. I also tried with a more recent build and had the same output.

  Input video is from sample-videos.com.

  The ffmpeg command I am running is :

  ffmpeg -y -i sample.mp4 -vcodec nvenc_h264 -pixel_format yuv420p -f mp4 sample-out-nvenc.mp4

  sample-out-nvenc.mp4 looks like this via ffplay or vlc :

  

  When I grab a frame using jpeg2, the colors appear normal, but the height is squished.

  ffmpeg -y -ss 15.5 -i sample.mp4 -vframes 1 -s 480x300 -f image2 grab.jpg

  

  The ffprobe results for the output (sample-out-nvenc.mp4) :

• How to make a basic youtube music bot work with searching titles instead of the URL

  21 janvier 2021, par Brandon

  Hello so i've followed this tutorial and added this code to my current bot to make it have a music bot function. Im wondering how to make the following code work with the youtube search function, for example right now I have to do !play URL but I would also like to be able to do !play name of song then the bot will search and play the most matched song.

  



  I am new to javascript but I know I shouldn't be looking for handouts, but some help would be appreciated.
