Make available resources about building/using newer versions with Meizu phones

[Daniel-Brum]

• I have checked that a similar feature request does not already exist.

Is your feature request related to a problem? Please describe.
I can't seem to make scrcpy work with my Meizu M6 Note phone whenever I use any version above 1.13. I've seen in another issue that the "culprit commit" was identified and that it did pose other problems, so I can understand it might be needed.
But there are some changes and new features that are present in newer versions that are pretty much inaccessible on some setups for that reason.

Describe the solution you'd like
However, if it's possible, I'd like to see an alternative to the phones that don't work with the change introduced in 1.14 and above. It doesn't even need to be prebuilt; having written resources about how to do it would be enough.

Describe alternatives you've considered
I've tried all the workarounds I've found in all related issues (like changing bitrate, encoder and even cables/ports). But none of them worked on newer versions.

I've seen in another issue that the "culprit commit" was identified and that it did pose other problems, so I can understand it might be needed.

I'm pretty sure we can make it work nevertheless, but I have no Meizu device.

Could you please help by testing this: #240 (comment)

Otherwise, building steps are described here: https://github.com/Genymobile/scrcpy/blob/master/BUILD.md

[Daniel-Brum]

Following the instructions in 240-comment, I get the same "freezing" problem, but there's no message displayed after

[server] INFO: ### 1
[server] INFO: ### 2
INFO: Renderer: direct3d
INFO: Initial texture: 1080x1920

Are there any logs I can try to get and paste here? If so, how can I do it?

[rom1v]

Please replace the server from v1.19 release by this one:
scrcpy-server sha256:4587ff4a115ca535cb6bf249cb09add2005e650e177b4335281e2d2df731d39d

Does it freeze? Please post the whole console output.

I get this:

[server] INFO: Device: Meizu M6 Note (Android 7.1.2)

and then nothing happens. Anything else I could try?

[rom1v]

And this one?

I've yet to try the encoder options though, but for now, no success.

[rom1v]

Oops, the last link was incorrect (it was the same as the first one). I fixed it. Could you retry, please?

[Daniel-Brum]

It worked! Thanks a lot!

I still have to check the new features (I got really attracted by the --max-fps option), but so far it's working fine.

[rom1v]

Fixed on dev: 8df42ce

Just to be sure, could you test the final version:
scrcpy-server sha256:7f2d14cf95ff3c490d6402100bf8f04261a5bc9bc050dfff83e6ee48ec5ac5d6

[Daniel-Brum]

It worked fine too. Would be nice having this server file "pinned" or something like that, if possible. Thanks a lot for your help!

[rom1v]

Would be nice having this server file "pinned" or something like that

What do you mean?

[Daniel-Brum]

Pinned is not the correct word for it, I suppose, but it would be nice to have the "alternative server" someplace easier to come by (though the ones who need it will probably search for it anyways, so not having that isn't a problem), Somewhere like in the Releases page for each version? Only if it isn't troublesome, of course.

[rom1v]

The problem is fixed on dev branch, so the next release will work as expected.

It was just a "bug" like many others, there are no backports to older versions.

[Daniel-Brum]

Oh, good to hear that then. Thanks!

[veselcraft]

Still not works on Meizu PRO 5

[rom1v]

@veselcraft Please test #3801 (comment). Does it work?

[veselcraft]

@veselcraft Please test #3801 (comment). Does it work?

Sure it does! It's smooth and the mouse controls works perfectly.

But i still have some glitches here, i think this is a problem on Flyme's side, not on scrcpy. Thanks for the fix anyways!

[rom1v]

If you record with adb shell screenrecord /sdcard/file.mp4, is the problem present on the resulting file?

It's present in any third-party screen recorder
