USB webcam stream to YouTube.com

[vl.vecera]

I need advice on a script to create YouTube.com streaming (RTMP) at least in HD 1920x1080 pixels at 25 fps. Preferably over GStreamer to be able to use GPU hardware.
How can I do that?

Hi,
We don’t have experience on this. Would need other user to share suggestion.

A user has shared a method of decoding Youtube videos on Jetson platforms:

how to use jetson nano hardware acceleration to play youtube videos

Unfortunately for me I’m getting quite skilled using python and gstreamer (2 things that I hate). So here you can find a simple solution: Install required packages: sudo pip install pafy sudo pip install --upgrade youtube_dl create a python file called “youtube.py” with this content: import pafy import os url = 'https://youtu.be/Bey4XXJAqS8' # youtube url to play vPafy = pafy.new(url) play = vPafy.getbestvideo() monitor_width = 1366 # target monitor width monitor_height = 768 # target …

Not same as your usecase but FYR.

This works for me, but if I want to use the 16: 9 format, more precisely the
1920x1080 resolution, gstreamer no longer works.
The sound beeps for more and I want to use the sound from the USB camera
there.

Can you advise?

height=1200, framerate=30/1, format=MJPG ! jpegdec ! queue ! omxh264enc !

Hi,
Could you go to gstreamer forum to get further suggestion? We don’t actually have experience about streaming to YouTube and may not be able to give good suggestion. Users in gstreamer forum are more experienced and may be able to give guidance. Once you get a working pipeline, you may replace software encoder with hardware encoder to enable hardware acceleration.
