I have an i5 520m and 8gb ram laptop. Now I wanted to ask… Can I stream in 720p with it?
It depends on what you want to stream.
I would like to respond to YouTube videos.
Should work. 720, 30fps. You can just test it. Get OBS, record something as a test and see if something is lagging.
Does the notebook also have a graphics card, and in which video codec do you want to stream?
Obs lagged with me have Streamlabs Obs there but ne CPU utilization of 80%
It has a graphics chip that is soldered to the motherboard.
Have you tried Linux?
He can't even stream 720p, let alone stream that.
So you only have one Intel GMA HD - Graphics. This GPU can decode Mpeg-2 and H.264 content, but the graphics chip can't help you with coding video material. Intel Quick Sync is only available from Sandy Bridge (Intel HD 2000/3000)
Does it really have to be a live stream and isn't it enough to first create the uncompressed video on the notebook, convert and compress it there, and only then upload it to YT?
No.
