I've used the following command to stream mp4 file to youtube :
ffmpeg -re -i merge.mp4 \
-c:v libx264 -preset veryfast -maxrate 3000k \
-bufsize 6000k -pix_fmt yuv420p -g 50 -c:a aac -b:a 160k -ac 2 \
-ar 44100 -f flv rtmp://a.rtmp.youtube.com/live2/<MYKEY>
I see the ffmpeg streams the data like that:
but yet the youtube streaming page shows nothing yet received:
Any idea what am I missing?

I am using following code to live stream video in youtube.
ffmpeg -y -loop 1 -i "still.jpg" -i "audio.mp3" " -c:v libx264 -pix_fmt yuv420p -crf 21 -r 1 -g 30 -keyint_min 5 -x264opts "keyint=5:min-keyint=5:no-scenecut" -s 1280x720 -tune zerolatency -b:a 128k -c:a aac -ar 48000 -strict experimental -f flv rtmp://a.rtmp.youtube.com/live2/steam-key.
I would like to set youtube live title and description in the above command. Is it possible?
It's about live video streaming to STEAM... with ffmpeg
I have this command
ffmpeg -re -i file-from-webcam.webm -deinterlace
-c:v libx264 -pix_fmt yuv420p -preset veryfast
-tune zerolatency -c:a aac -b:a 128k -ac 2 -strict -2 -crf 18
-r 30 -g 60 -vb 1369k -minrate 1369k -maxrate 1369 -ar 44100 -x264-params "nal-hrd=cbr"
-vf "scale=1280:720" -profile:v main
-f flv "rtmp://ingest-rtmp.broadcast.steamcontent.com/app/steam_...."
but after a few seconds, the stream stops and the log of steam says
Make sure your upload key-frame interval is set to 2 seconds
and use constant bitrate (CBR).
Limit your encoders group of picture (GOP) to at most two times your framerate.
but I do have -x264-params "nal-hrd=cbr" and -r 30 -g 60 framerate 30 GOP 60...
Is there something wrong in the ffmpeg command ?
Or is it linux server related ?
**** The SAME ffmpeg command work very nicely in youtube, twitter, twitch, dlive, facebook, etc...
so what I'm I missing to get it work for steam ?
ffmpeg -re -i file.webm -deinterlace -c:v libx264 -preset veryfast -tune zerolatency -c:a aac -b:a 128k -ac 2 -r 30 -g 60 -vb 1369k -minrate 1369k -maxrate 1369k -bufsize 2730k -ar 44100 -x264-params "nal-hrd=cbr" -vf "scale=1280:720,format=yuv420p" -profile:v main -f flv "rtmp://ingest-rtmp.broadcast.steamcontent.com/app/___key___"
-crf and -b:v/-vb are mutually exclusive. It's likely your -vb was being ignored. Since you want a specific bitrate remove -crf.
-maxrate 1369 was missing the k.
Add -bufsize. See FFmpeg Wiki: Encoding for Streaming Sites.
No need for -strict -2. Users always add that without knowing why. (It was for the old AAC encoder before 2015.)
Make sure your input has audio. Some sites like YouTube require audio. If it does not have audio use the anullsrc filter to generate silent audio.
I want to stream my video to 4 destinations. My input signal needs to be recoded to "H.264 AAC", so I want to send it to my server. This works already.
Client -> Server with ffmpeg -> Destinations
Now I have a performance problem: One should get the stream in 1080p and two in 720p.
So it would make sense to first get the stream in the desired formats H.264 1080p and AAC with 30 FPS and then calculate the stream once, send it 1:1 to the two HD targets.
and create a 720p stream in parallel and send it to the two remaining destinations.
What is the best way to do this on a Ubuntu 16.04 machine?
My previous approach:
ffmpeg -i rtmp://livestream.domain.example/live/<key> \
-threads 2 -s hd1080 -preset veryfast -f flv rtmp://destination1.example/live2/<key> \
-threads 2 -s hd1080 -preset veryfast -f flv rtmp://destination2.example/live2/<key> \
-threads 1 -s hd720 -c:v libx264 -c:a aac -preset veryfast -r 30 -g 60 -b:v 3000k -f flv rtmp://destination3.example/x/<key> \
-threads 1 -s hd720 -c:v libx264 -preset veryfast -c:a aac -f flv 'rtmps://destination4.exmple/rtmp/<key>'
You can see the repetitions in the code. :-/
Use the tee muxer:
ffmpeg -i rtmp://livestream.domain.example/live/<key> \
-filter_complex "[0:v]scale=-2:1080,fps=30,split=outputs=2[1080a][1080b];[0:v]scale=-2:720,fps=30,split=outputs=2[720a][720b]" \
-map "[1080a]" -map "[1080b]" -map "[720a]" -map "[720b]" -map 0:a \
-c:v libx264 -c:a aac -preset veryfast -g 60 -b:v 3000k -maxrate 3000k -bufsize 6000k -f tee \
"[select=\'v:0,a\':f=flv:onfail=ignore]rtmp://destination1.example/live2/<key>| \
[select=\'v:1,a\':f=flv:onfail=ignore]rtmp://destination2.example/live2/<key>| \
[select=\'v:2,a\':f=flv:onfail=ignore]rtmp://destination3.example/live2/<key>| \
[select=\'v:3,a\':f=flv:onfail=ignore]rtmp://destination4.example/live2/<key>"
I've been using ffmpeg to stream m3u8 files to twitch, and similar platforms,
through this script:
#! /bin/bash
PRESET="ultrafast"
PLATFORM="rtmp://(platform_streaming_url)"
SOURCE="source of the stream(m3u8)"
STREAMING_KEY="platform_personal_streaming_key"
ffmpeg \
-re -i "$SOURCE" -vcodec libx264 -preset $PRESET -maxrate 3000k -b:v 2500k \
-bufsize 600k -pix_fmt yuv420p -g 60 -c:a aac -b:a 160k -ac 2 \
-ar 44100 -f flv -s 1280x720 "$STREAMING_KEY/$PLATFORM"
But usualy the source of those streams are private, and to stream from private sources i have to use other solutions that take a lot of my computer resources.
So is there a way to stream through ffmpeg, knowing that i have the credentials of that private stream.
I need setting keyframe for youtube but not working. Is on linux Debian.
ffmpeg -i "test.flv" -vcodec libx264 -x264-params keyint=120:no-scenecut -sameq -pix_fmt yuv420p -re -ar 44100 -b:a 128k -bufsize 2048k -vb 400k -maxrate 800k -deinterlace -acodec libmp3lame -preset medium -g 30 -r 30 -f flv "rtmp://a.rtmp.youtube.com/live2/"
I have error Unrecognized option 'x264-params'
