Camera video issues

- [x] I have read the [FAQ](https://github.com/Genymobile/scrcpy/blob/master/FAQ.md).
- [x] I have searched in existing [issues](https://github.com/Genymobile/scrcpy/issues).

**Environment**
- OS: Windows
- scrcpy version: Manual build
- installation method: Manual Build
- device model: Redmi Note 11T Pro`(xaga)`
- Android version: 12

**Describe the bug**
On my device, when the camera size is set to `1920x1080`, the camera function can be used normally. But when the camera size is specified as (also the default) `4640x3472`, the camera cannot be displayed normally, and FFmpeg will also have errors.

It's show like that


Start by reproducing the reported command with the Redmi Note 11T Pro setup and compare camera sizes 1920x1080 and 4640x3472. Use the provided FFmpeg decoding errors and the camera video path as the investigation boundary; done means the high-resolution camera stream displays without decoding errors.
