这个问题是,线程事件投递问题,理论上来说,应该不会报错才对,我一般直接使用release编译调试,你可以试一下

@itisyang 感谢回复,我试过了,好像还有,不过点击ignore倒也不影响使用。VS+QT刚开始入坑,请问有推荐的入门博客或者资料没,多谢!

@itisyang 收到!再请教个问题,用这个播放器放高码率的rtsp流,延迟比VLC要大好多(1s以上),如果要做调优的话应该如何做呢?是调整datactl.h里面的一些比如MAX_QUEUE_SIZE,SAMPLE_ARRAY_SIZE,#define VIDEO_PICTURE_QUEUE_SIZE 3
#define SUBPICTURE_QUEUE_SIZE 16
#define SAMPLE_QUEUE_SIZE 9
#define FRAME_QUEUE_SIZE FFMAX(SAMPLE_QUEUE_SIZE, FFMAX(VIDEO_PICTURE_QUEUE_SIZE, SUBPICTURE_QUEUE_SIZE)) 之类的,还是必须得对ffmpeg的编码调用做优化?视频小白一个,还请多指教,感谢!

@itisyang 网上看到有 “-fflags nobuffer -flags low_delay -framedrop -strict experimental”,用ffplay试了下,看起来能把rtsp的延迟降低到.5s左右。还在尝试
