FFMPEG No encoder found for codec id 8
3 septembre 2018, par raspiboeleI’m using a Raspberry Pi to restreem a (https) .m3u8 stream, to a local MJPEG-stream with FFMPEG.
Becaus I have a Nest Cam / Nest Hello and I want to import that stream into my Fibaro Homecenter (Smarthome Basestation), but the Fibaro Homecenter only eats the MJPEG format. So I made a Raspberry Pi with FFMPEG to do the trick.This is my /etc/ffserver.conf file :
HTTPPort 8090
HTTPBindAddress 0.0.0.0
MaxHTTPConnections 2000
MaxClients 1000

It is frutstrating me, because I’m looking for a solution for three days now. I can’t even find a list of encoders and the coresponding ID’s. Do I have to enable maybe something in the ./configure ?My target is to get a stream at : http://localhost:8090/test1.mjpg
Can anyone help me please ?

generating silence audio using ffmpeg with specific bitrate and duration time less than one second cannot get the audio with the desired bitrate
28 août 2018, par bambooomI’d like to generate a silence audio file using ffmpeg with specific bitrate and the duration is less than one second. I found that the generated audio file does not have the desired bitrate. But if I expand the duration to 2 seconds, the bitrate seems to be correct.
For example :
ffmpeg -f lavfi -i anullsrc=r=22050:cl=mono -t 0.3 -acodec mp3 -ab 48k -y silence.mp3
The generated silence.mp3’s bitrate seems not 48kb/s :

How do I make it work on a Windows 10 machine with cuda ?
