視頻會議軟件開發(fā)源碼(視頻會議軟件源代碼)
本篇文章給大家談?wù)勔曨l會議軟件開發(fā)源碼,以及視頻會議軟件源代碼對應(yīng)的知識點,希望對各位有所幫助,不要忘了收藏本站喔。
本文目錄一覽:
請問那里購買視頻會議源代碼?
現(xiàn)在視頻會議源碼價格很便宜的。
CoolVideo視頻會議 仿視高,仿好會議.源碼比較齊全。
可以在百度里面搜下。
安卓 視頻會議 開源的源碼,有誰可以提供一下嗎?
開源碼 不難找,可是 視頻會議, 不容易吧,要是做開發(fā)就去論壇上學習,那里高人比較多。機鋒,3G,安卓論壇,貼吧,都可以去看看的
VB編寫視頻會議軟件
樓上的不要說vb做不了,關(guān)鍵是你不會
這里有個,可以看看
