DTX mode is not implemented in ffmpeg
14 août 2023, par ShahrizwanError :
[sdp @ 00000262b33bd980] Too much speech data in the RTP packet ?0 Camrnb @ 00000262b3408c80] Corrupt bitstream


[sdp @00000262b33bd980] Too much speech data in the RTP packet ?0


Recyc [amrnb@000002473b118980] dtx mode is not implemented. Update your FFmpeg version to the newest one from Git. If the problem still occurs, it means that your file has a feature which has not been implemented.


Please help me, what should I do ?


I am trying to use radio to send voice to pc. And it uses the AMR-NB codec.

FFMPEG : Youtube streaming quality and speed issues
25 février 2020, par Alex ParamonovI am trying to make a reliable stream from my Icecast/Shoutcast servers to Youtube live. The command that I use is :
ffmpeg -v verbose -framerate 30 -loop 1 -i /var/image.jpg -re -i http://127.0.0.1:4700/radio -c:v libx264 -preset ultrafast -b:v 2250k -maxrate 6000k -bufsize 6000k -c:a copy -ab 128k -s 1920x1080 -framerate 30 -g 60 -keyint_min 60 -f flv rtmp://a.rtmp.youtube.com/live2/xxx
As you can see I am using recommended bitrate for Youtube, insert keyframes every 2 seconds and streaming at 30 frames per second.
The stream is working but after running for some time two thing are happening :- FFMPEG
speed
falls from 1x to something like0.998x
- Youtube starts complaining that video stream speed is slow, markes the quality as bad and sometimes video starts buffering.
Why is this happening ? CPU load is normal, connectivity is ok (the stream is running on a 1Gg/s dedicated server).
Since in my example above I am streaming a single image as a logo of the stream I also tried to generate a short 30 seconds video with that image and broadcast that video instead of an image, but that did not help as well.
The command I used for conversion :
ffmpeg -framerate 30 -loop 1 -i /var/image.jpg -c:v libx264 -preset ultrafast -tune stillimage -b:v 2250k -minrate 2250k -maxrate 6000k -bufsize 6000k -framerate 30 -g 60 -keyint_min 60 -t 30 out4.mp4
And broadcast with
ffmpeg -stream_loop -1 -i out4.mp4 -re -i http://127.0.0.1:4700/radio -c:v copy -c:a copy -framerate 30 -g 60 -keyint_min 60 -f flv rtmp://a.rtmp.youtube.com/live2/xxx
ffmpeg version is
4.1.1
