livekit
保存本地视频黑屏，但是有声音，
保存视频操作代码如下，按照官方实例写的 room = LiveKit.create( appContext = applicationContext, overrides = LiveKitOverrides( javaAudioDeviceModuleCustomizer = { builder -> builder.setSamplesReadyCallback { samples -> videoFileRenderer?.onWebRtcAudioRecordSamplesReady(samples) } } ) )
track?.addRenderer(videoFileRenderer)
private fun disconnectRoom() { videoFileRenderer?.release() videoFileRenderer = null }
保存的时候报错如下，保存下来的视频是黑屏，有声音，文件特别小，时长好像还少了几秒

Sorry, we took the code from elsewhere and it seems to be pretty old. I don't really know MediaCodec usage very well myself, so it's unlikely we'll be able to fix up the example code here for a while.
You can use the original VideoFileRenderer.java provided by libwebrtc, but be warned that this writes raw uncompressed frames and will result in very large video files.

您好，我直接运行的官方sample-app-record-local，只修改了url和token
保存的视频也是黑屏
我想知道是手机问题吗，还是说移动端sdk和后台sdk版本必须要一致才可以
The backend SDK won't have any relevancy here as the example code for recording the video. Your best bet would be to look up working MediaCodec examples for recording a Surface and going from there.

通过以上日志您能看出来MediaCodec有什么问题吗

Unfortunately I didn't write the above code (the original is from https://github.com/flutter-webrtc/flutter-webrtc/blob/main/android/src/main/java/com/cloudwebrtc/webrtc/record/VideoFileRenderer.java) and I don't know much about MediaCodec to help here.
