use CDP screencast API to record mp4 videos

[nirtal85]

Currently, there is no real option without complex scripts to record in headless mode
CDP provides screencast API selenium already implemented but does not use it (and no guides on using it)
frameworks like cypress puppeteer and playwright use it already.

start screen cast
devTools.send(Page.startScreencast(Optional.of(Page.StartScreencastFormat.JPEG), Optional.of(100), Optional.of(1920), Optional.of(1080), Optional.of(1)));
stop screencast
devTools.send(Page.stopScreencast())
and an event listener which receives the raw data (which are the frames)

https://chromedevtools.github.io/devtools-protocol/tot/Page/#method-stopScreencast

can you please add an example how to use it to generate mp4?

Hello Nir The creation of the movie from frames is outside of Selenium CDP scope. There must be solitions for that. To collect frames is easy with CDP: see commit 99e16ef it implemets the test which collects the screencast frames Thanks Serguei Kouzmine On Monday, February 6, 2023, 02:56:25 PM EST, Nir Tal ***@***.***> wrote: Currently, there is no real option without complex scripts to record in headless mode CDP provides screencast API selenium already implemented but does not use it (and no guides on using it) frameworks like cypress puppeteer and playwright use it already. start screen cast devTools.send(Page.startScreencast(Optional.of(Page.StartScreencastFormat.JPEG), Optional.of(100), Optional.of(1920), Optional.of(1080), Optional.of(1))); stop screencast devTools.send(Page.stopScreencast()) and an event listener which receives the raw data (which are the frames) https://chromedevtools.github.io/devtools-protocol/tot/Page/#method-startScreencast https://chromedevtools.github.io/devtools-protocol/tot/Page/#method-stopScreencast can you please add an example how to use it to generate mp4? — Reply to this email directly, view it on GitHub, or unsubscribe.
