使用player_open("vfwcap", GetSafeHwnd(), NULL);打开摄像头画面有延迟，延迟大概在1秒到2秒左右 使用vlc和mpc-hc都是正常的

环境：win10+vs2010，PC：realme笔记本

设置 fanplayer.ini 的下面的参数： avts_syncmode = 2; video_bufpktn = 1; audio_bufpktn = 1;

试试

dshow 方式试过没，我这边测试 dshow 模式是正常的。

试下修改 player_prepare 这个函数里面，把 player->init_params.avts_syncmode 设置为 2

我的摄像头名称是 720p HD Camera，我这样打开后没有图像 player_open("dshow://video=720p HD Camera", GetSafeHwnd(), NULL);

fanplayer dshow://video="open_uvc_cam#Camera" 或者 fanplayer dshow://video="open_uvc_cam#720p" 用这个试下

设置了这两个都不行 player_open("dshow://video=open_uvc_cam#Camera", GetSafeHwnd(), NULL); player_open("dshow://video=open_uvc_cam#720p", GetSafeHwnd(), NULL); 一直提示报错，如下： unable to decode APP fields: Invalid data found when processing input real-time buffer [open_uvc_cam#720p] [video input] too full or near too full (82% of size: 3041280 [rtbufsize parameter])! frame dropped!
