Improvement
Choose the stream encoder
The share dialog shows the encoders on your machine, recommends the best one and tells whether each uses the graphics card or the processor.
Encoder in the dialog
Pick H.264, AV1, VP9 or VP8. The recommended one comes first and each shows GPU, CPU or GPU unconfirmed.
Actually checked
In the first seconds, DevColab checks whether the graphics card is encoding. If not, it lets you know and uses another encoder next time.
Complete diagnostics
The streamer's diagnostics list this machine's encoders and the real encoder, ready to copy.
