偷偷跟你講,
圓剛的FAE工程師不可能懂這麼多的啦
跟HDCP沒有關係
因為你的hdmi來源都沒有HDCP保護
我告訴你為何不能動?
usb在擷取卡的世界中有兩種傳輸方式,一個是ISO MODE,一個bulk mode
bulk mode:同一時間可以插入兩支以上
iso mode:同一時間,不一定可以插入兩支以上 (兩支有可能成功也有可能失敗)
同一時間,一定不能插入三支以上
因為圓剛那兩支擷取卡都是USB ISO MODE,
你的電腦剛好無法插入兩支
也許找別台電腦,搞不好可以喔
解決方法:(以下是保證可以使用的,沒有模稜兩可)
同時插入兩支: iso mode 擷取卡 +bulk mode擷取卡 或 bulk mode擷取卡 x2
同時插入三支: iso x1 +bulk x2 或 bulk x3
以此類推
以下是實際demo
同時插入四支擷取卡,同時可以一起使用

※ 引述《demyou (Marshmallow)》之銘言:
: 不知能否po在電蝦板,有走錯路也請指正,謝謝!!
: 最近在嘗試直播環境的建置
: 目前有問題的是,想將Macbook Pro(2015)的HDMI訊號
: 輸進一台Windows作業系統的筆電裡(MSI-WT726Q),再藉由OBS做出有子母畫面的直播
: 連接狀況如下:
: Macbook→GC510擷取卡→ =Win筆電(obs)= ←GC550擷取卡←DV
: 但Macbook端進來的訊號是黑畫面,詢問擷取卡廠商的工程師
: 對方表示可能是HDCP的訊號保護問題
: 於是也買了HDCP破解器,但依然無法解決問題
: 想請教有沒有神人大大 知道這樣的問題該如何解
: 感謝各位!!

使用OBS studio的直播教學
(OBS參數設定 雙直播 去背 字幕 跑馬燈 多台攝影機轉場...)
