Possible to use this for radio station?

code below is candidate code for broadcasting multiple mp4 to youtube live

Is it possible to use ffmpeg-youtube-live instead?

[scivision]

How about https://github.com/scivision/ffmpeg-youtube-live/blob/master/FileGlob2YouTubeLive.py

[ghost]

@scivision Awesome. I can't wait to use that :) Will it be possible to stream just mp3 files?

For now, I am using Icecast to stream my mp3 files, and use ffmpeg to send youtube live. avconv -loop 1 -i /MUSIC/xt-hd.png -i http://localhost:8080/mp3 -r 30 -acodec aac -strict -2 -c:v libx264 -strict experimental -b:a 128k -pix_fmt yuvj444p -b:v 256k -minrate 128k -maxrate 512k -bufsize 768k -f flv rtmp://a.rtmp.youtube.com/live2/[KEY]

From: http://akos.me/2017/stream-icecast-stream-to-youtube/

Or I am trying to implement this too with Icecast

ffmpeg -re -loop 1 -framerate 2 -i test1.jpg -i https://xxxxxxxxxxx:8080/mp3 -c:a aac -s 2560x1440 -ab 128k -vcodec libx264 -pix_fmt yuv420p -maxrate 2048k -bufsize 2048k -framerate 30 -g 2 -strict experimental -f flv rtmp://a.rtmp.youtube.com/live2/[KEY]

I can't determine which way would be more stable.. Can i ask you how do you think about this?

[scivision]

I am tied up till later this month. I'll try to run test live stream of several such cases on Windows and Linux.

Basically you can think of the Python script as a command generator--it computes the "best" options or at least "good" options for several different YouTube Live scenarios, optionally running ffmpeg or avconv for you with those options.

[ghost]

@scivision Good. It would be awesome to create my own stream channel with just one simple command! let me know if there is what I can :)

[scivision]

yes I agree that's the goal of the program, to find the best command for your given computer configuration.

What would be the problem?

[scivision]

The code has been updated to handle several more use cases such as yours. Now with the latest code, you can stream a bunch of audio-only .mp3 files. You do need to pick a static image (say sunrise.jpg or mylogo.png etc.) as a background

You would type

python FileGlob2YouTubeLive.py /root/radio "*.mp3" -i mylogo.jpg

[ghost]

@scivision Just can't wait to use that! I'll try it soon and feedback for you. thanks for your works and keep moving!

[scivision]

Great! You can also add the -loop option to endlessly repeat the globbed list of files (endless live stream).

[ghost]

@scivision And always Thanks for your code! I finally tested new code here, and in conclusion, it is working quite nice. But I got some few weird situation. One of them was that at some point, it just keeps loop at a specific range (after nice stream period almost 2hr), but youtube showing green status bar. The FFmpeg's encoding speed was 3x, so I thought that was the problem. What I did to fix that was changing thumbnail to more big one (to reduce encoding speed), and get rid of DVR option from youtube live dashboard. And now It's going quite well, almost 24hr. but as the low encoding speed, sometimes it's quite laggy. I think I should find some ways to stream with fast encoding speed but without DVR for now 🤔

[scivision]

@transifex3 this issue with excessive encoding speed was recently solved.

Now with the latest code, you can stream a bunch of audio-only .mp3 files. You do need to pick a static image (say sunrise.jpg or mylogo.png etc.) as a background

Any way to stream multiple mp3 files (loop) with the animated background? I can't loop music with the animated backgroud.
