[NativeDecoder] Playback stops after settings changing

[pigass0512]

Hi master,

Now I got another question that after I clicked Native Decoder stream link and change video setting, the device stream had started, but after few seconds, the stream had stop... How can I fix it? Thanks!

Hi. Yeah, I can reproduce it, will investigate.

BTW, in my tests broadway decoder always was more efficient and stable than native.

I only can use Native as decoder, the other two still display black screen on my web page...haha this is my another question..

Hi master, windows 10 and chrome latest version.

Tested on Chrome 83.0.4103.97 on Win10 x64, works fine here.

I had upgrade Chrome version and Native stream become fluently, but the other two still black...

but the other two still black...

Try to move or open something, so picture on the screen is changed (I usually run clock/stopwatch for tests).
Encoder does not send frames when there are no changes on the screen (shouldn't be a problem on very first connection).

The method seems not works for me, and the stream still stop playing in the few seconds..
And the other two decoders are still black after I launch an APP.

Hi @drauggres master,
Does any update of this issue?

[drauggres]

Nope. No luck and no ideas.
Only thing I was able to find is that you can resize window (e.g. press F11 to open browser in fullscreen), press change video settings and player will unfreeze. But still don't why it freezes in the first place.

I'm thinking about different approach:

1. use original scrcpy instead of my fork
2. create web socket proxy server
3. configure all streaming parameters before connection

Downsides here are:

• unable to change video setting on the fly, it will require reconnection
• maybe be problems with simultaneous access of a device from more than one client (probably I can make it work)

[pigass0512]

Unfortunately, after I resize my device window, it still freeze in the further seconds..that's weird..

[drauggres]

I changed default frame rate value for native decoder. In my tests it is more stable now.

@pigass0512, please try again (master branch).

UPD: just tried it on linux/chrome, still freezing.

Hey guys, try develop branch with broadway or tinyh264 decoders. If problem is still there, please open a new issue and specify OS, browser version and everithing that you think might be relevant.

[pigass0512]

Hi master @drauggres ,

After I pull develop branch and build the service, still only native decode can work..others are black screen..
I will open another issue for discuss with other decoder can not work problem, is that okay?
