OTT markets

• YouTube: the earliest social video platform, making profit by display & pre-roll ads. seems that hard to cover its costs, thus subscription model called youtube red was released recently.
• Facebook: the largest social friendship platform, making profit by display ad. try to increase traffic by original contents of instant article, video and live streaming. however, video costs much more than image/text. Seems than cost of Facebook ad increases drastically to compensate it recently.
• Netflix: the well-known OTT vendor, making profit via subscription model. Seems working by balancing the cost and the subscription fee.

ffmpeg keyframe interval

...So "keyint=60" for 30FPS, "keyint=120" for 60FPS, etc. I'm heard OBS has an option for it soon. This spec is ok for YoutTube and Facebook live.

Facebook Live, Part 2

Facebook Live 終於上線啦! 有些眉角需要注意。

• 一篇貼文的RTMP url只能用一次! 嘗試連第二次會error，貼文得換一篇。算是一種安全機制吧，避免[蓋台」。
• video profile沒有嚴格限制，比起YouTube Live 寬鬆，High profile也跑得不錯。但有上述連一次限制，rtmp穩定度就很重要，得確保訊號源很穩，不然卡頓時，你是不能換訊號的。
• YouTube的容許度就大一些，只有初始連結比較要求。
