hello: When I deploy the service to a Linux system, the following error occurs: org.bytedeco.javacv.FrameRecorder$Exception: avformat_write_header error() error -22: Could not write header to 'null' at com.junction.entity.FFmpegFrameRecorder.startUnsafe(FFmpegFrameRecorder.java:946) at com.junction.entity.FFmpegFrameRecorder.start(FFmpegFrameRecorder.java:425) at com.junction.entity.FFmpegFrameRecorder.start(FFmpegFrameRecorder.java:420) at com.junction.entity.RtmpPush.push(RtmpPush.java:191) at com.junction.entity.RtmpPush.push(RtmpPush.java:304) at com.junction.entity.RealPlay.run(RealPlay.java:225)

It looks like you're trying to encode an empty image, that's not going to work. Make sure all your video frames are valid images.

Thanks!

Actually, it looks like you're trying to create an interleaved stream, but you're specifying no audio channels. You'll either need to not do interleaved, or add an audio channel.
