应该是`player.setProperty("reader.starts_with_key", "0")`，日志里没有这种就对了`video stream#0 1st [email protected] without key frame will be dropped!!!!!!!!!!!!!!!!!!!`

什么系统？如果是苹果的话感觉是CAMetalLayer默认的颜色，如果没有视频帧，我这边不会渲染任何东西，我用glfwplay测试结果是用metal就是紫色，opengl是黑的。你可以写个最简单的MTKView验证下。要去掉的话得强行喂一帧，但好像还是会紫色闪一下 ```cpp uint8_t rgba[64*64*4] = {}; const uint8_t* data[] = { rgba }; VideoFrame frame(64, 64, PixelFormat::RGBA); frame.setBuffers(data); player.enqueue(frame, vid); ```

try `vainfo` command.

what about other files?

should be fixed in the latest build. see https://github.com/wang-bin/mdk-sdk/issues/261#issuecomment-2731647168

can you try binaries from github actions to find out which commit breaks?

I expect that commit can fix the frozen but not introduce the frozen. I need your test program to debug, can you send me a binary?

Yes. Working on it.

in heavym exported video all frames are the same. in boxes example + the latest sdk, i keep a few video items, frames after seek are correct. I also tested...

renderVideo() return value is correct in boxes example, what about heavym?
