[Xiaomi Android 14] Light grays appearing as white only for scrcpy #4756
Comments
What do you mean by adb here? screenrecord ( If you record then play the file (with VLC or Firefox for example), does the problem occur? |
|
Yep, I meant With |
With this one can see that after some specific gray value it just outputs white 
|
|
In the console output, which renderer is used? For example: I guess this is If so, could you try other values: |
|
All of them look the same (partially horrible) way, even software, which was unexpected to me 😆 |
|
I've experienced the same issue before (not with scrcpy) and it was the encoder which was at fault (switching from the hardware encoder to x264 fixed it). I don't know if its possible the device is somehow defaulting to a different h264 encoder on A14? Though not sure why recording to a .mp4 would fix it. |
|
|
You can list and change the encoder.
Maybe your hardware encoder encodes with different parameters and set some metadata to handle color, and scrcpy does not handle them (either during the YUV-to-RGB conversion, either during rendering) while VLC does. If you could try the same device on another computer with another OS (on Linux for example), that might help (or not). |
|
Same as #4282 Maybe the device captures in HDR but SDL can't render them correctly? |
|
I had the same problem, scrcpy and android studio mirror screens have a noticeable color difference |

Some newer XiaoMi devices encode in full color range. I found this fix, but updating it in every frame might not be the most efficient method: (apparently libsdl-org/SDL#7083 is not true, FFMpeg and SDL both use JPEG to refer full color range) diff --git a/app/src/display.c b/app/src/display.c

Environment
Describe the bug
Light grays are not shown. They are displayed as white. ADB and Android Studio render the colors correctly.
I am pretty sure this is happening since I upgraded the phone from Android 13 to Android 14 some weeks ago.
With a
[Google] google Pixel 6 (Android 14)the issue is not occurring, which means the device is somehow influencing this.AS:
