• ffmpeg stream input sdp shows warning keyframe missing

  27 mars 2021, par Doua Beri

  I'm using ffmpeg 4.3.2.
I'm trying to forward a stream to a rtmp server having sdp file as input

  


  Opening the sdp file with VLC everything is working great. The same thing happens when I use ffplay

  


  ffplay -i rtp-forwarder.sdp -protocol_whitelist file,udp,rtp


  


  The problem starts when I start streaming to a rtmp server. The audio is good but the video is just a black screen. I event tried to stream to youtube rtmp server but it didn't work.

  


  I'm new to ffmpeg. Let me know if I'm missing something.

  


  I'm using this command

  


  ffmpeg -protocol_whitelist file,crypto,udp,rtp -re -i rtp-forwarder.sdp -c:v libx264 -b:v 3000k -maxrate 3000k -bufsize 6000k -pix_fmt yuv420p -g 50 -c:a aac -b:a 160k -ac 2 -ar 44100 -f flv rtmp://localhost/live/test


  


  The sdp file content is like this

  


  v=0
o=- 0 0 IN IP4 192.168.1.49
s=Pion WebRTC
c=IN IP4 192.168.1.49

• Bad output from ffmpeg running on raw video from Wear OS device

  17 juin 2020, par lcj

  I am following these instructions regarding capturing and converting video from a Wear OS device, and I am running into problems. I get a video and I can tell it is my screen but it seems to be warped. This should be a green check with some white text.

  



  

  



  There is a lot of noise when I run this :

  



  ffmpeg -f rawvideo -vcodec rawvideo -s 400x400 -pix_fmt rgb24 -r 10 -i video.raw -an -c:v libx264 -pix_fmt yuv420p video.mp4
