![更新至 ubuntu 22.10 后 Mpv vaapi 无法正常工作](https://linux22.com/image/950072/%E6%9B%B4%E6%96%B0%E8%87%B3%20ubuntu%2022.10%20%E5%90%8E%20Mpv%20vaapi%20%E6%97%A0%E6%B3%95%E6%AD%A3%E5%B8%B8%E5%B7%A5%E4%BD%9C.png)
我之前在 Ubuntu 22.04 上使用过 vaapi(通过 intel_gpu_top 检查),但在更新到 22.10 后,它突然停止工作。
按下热键 CTRL + H 激活硬件解码,它会冻结然后变为绿色或出现故障(音频正常)。

发现问题,这是一个内核错误,回滚到5.15.0-53-generic
现在 VAAPI 又可以正常工作了。
看来,这是一个问题5.19.0-23-generic
。
