Support for the reMarkable2 with high fps. #35

Closed Foxei closed 3 years ago

Foxei commented 3 years ago

Hello everyone, this is a working solution for the issue #28 and is a addition to the pull request #31. The code is tested on a reMarkable2 and working with 12-14 fps which is a great improvement over the 2-3fps with the current solution. The dd, head and tail combination is replace with a custom C program that dumps the memory. The executable reDump is Open Source and can be found here.

Tested this and seems quite fast. Although the image quality is definitely lower than rmview. I haven't compared to the main branch of restream though. Is there anyway to easily check fps and resolution during testing?

Hello @Lxstr, to my knowledge bordeigol has not yet merged ssh support for the remarkable 2 into the main rmView project. Which fork of rmView have you compared this to?

It might be though that there is a difference in scaling. reStream uses the ffplay command to display and scale the image and rmView performers the scaling with a QGraphivsView. This most certainly makes a difference but I honestly do not know to what extent.

I have to fail you here because I do not know if ffplay even supports displaying such statistics. I may have to correct my statement in the pull request. I cannot ensure that actually 12-14 FPS are displayed I only can ensure that reDump and lz4 are making the image available with 12-14 FPS. If the receiving side can handle that is not my job anymore. 😄

Hi @Foxei, thank you for the PR! (And thank you for poking me to perform my duties as a maintainer.)

Unfortunately, I have made a program like reDump already in Rust, and prefer to use my own version. I hope you understand.

My apologies for not releasing it earlier and saving you this work.

Hello @rien, I understand no hard feelings. 😉 Do not think I will not try to make additions to you work in the future though. I love this hole streaming and dumping think.
