Only MseDecoder can work, other decoders display black screen. about ws-scrcpy HOT 12 CLOSED

Using these options by default is not an options.
I'm thinking about using profile=1,level=1 automatically on Android 10+ and keeping - for others, but I haven't decided yet.
Also I want to add possibility to change "codec options" (and new encoder parameter) at runtime same way as video settings.

from ws-scrcpy.

To be clear, all three other decoders work for me on mac/linux/windows on chrome/firefox and safari. I don't know where to look at.
Any help or additional info (maybe there are logs in the console in dev-tools) appreciated.

from ws-scrcpy.

This situation may be caused by a special device(Android mobile phone), because the three decoders work for my first device, but not work for another.
Another reason is because broadway.js only support low quality video streaming.

Can you share the first two video frames that come over the websocket?
They have 0000 0001 67 and 0000 0001 65 bytes at the beginning.

Upd: base64 is prefered.

from ws-scrcpy.

Also please try to change this line to const CODEC_OPTIONS = 'profile=1,level=1';:

You will need kill app_process, this parameter is passed as an argument to the scrcpy-server.

Hi master,

But I can not using any decoders after I build the service with v0.4.1.....OMG!!
I had reboot my device and using the same wifi network, but still cannot launch the screenshot....lol

After reboot do you open "device list" page first or directly /#!action=stream&? Server is installed after devices detection, which happens only when "device list" page requested.

Hi master,

My steps as below :

1. Reboot my mobile device.
2. Git clone the project with v0.4.1
3. npm install and start the service.
4. Go to Device list web page.
5. Click one of decoder in list.

Also please try to change this line to const CODEC_OPTIONS = 'profile=1,level=1';:

ws-scrcpy/src/server/Constants.ts

Line 17 in 79098c6

const CODEC_OPTIONS = '-';

You will need kill app_process, this parameter is passed as an argument to the scrcpy-server.

Tried on OnePlus 6 (Android 10): with profile=1,level=1 Broaway and TinyH264 work just fine.
Will add fix to the next release.

UPD: but it breaks encoder on some devices with android 6...

works,better write in README.MD

I have implemented a configuration dialog in the develop branch.
Now, before opening the stream, you can configure video settings, including codec options and encoder.

Changing encoder look like a simpler solution than setting codec options.

If anyone can test it, please let me know the results.

from ws-scrcpy.

To summarize:

1. Broadway.js and Tiny H264 are capable to decode only video encoded with Baseline profile
2. To change profile you can:

• specify codec option (not necessary exactly profile=1,level=1, but it seems to work in some cases, for more information see --codec-options option in scrcpy)
• select different encoder (hoping it has Baseline as default profile)

Otherwise you can use MSE based player, at the momen we use here xevokk/h264-converter.
