关于vlc二次开发问题，视频花屏，延迟很长

Question

目前公司用vlc连接网络摄像头，连海康的延迟大概两秒，视频正常，这里延迟几秒没关系，但是连接华为的摄像头延迟能有几十秒，而且还会有花屏现象，开始持续时间较短，后面持续时间越来越长，注：设置相同的宽和高，华为摄像头分辨率明显比海康的高

Answer 1

设置回调函数
void ConnectNetworkCamera::setCallBack()
{
//imshow("test", *m_context.image);
waitKey(1);
s_context.ctx = &m_context;
s_context.conn = this;
libvlc_video_set_callbacks(m_mp, ConnectNetworkCamera::lock, ConnectNetworkCamera::unlock, ConnectNetworkCamera::display, &s_context);
libvlc_video_set_format(m_mp, "RV24", VIDEO_WIDTH, VIDEO_HEIGHT, VIDEO_WIDTH * 24 / 8); // pitch = width * BitsPerPixel / 8
// int ret = libvlc_media_player_play(m_mp);
// showfps();
m_thread_handle = CreateThread(NULL, NULL, threadProc, this, NULL, NULL);
