Recently, I am working on decoding projects and have access to a lot of open source code. I think it is fun, just like a project similar to online live video forwarding.
It happened that Brother Chen bought a server and wanted to borrow his server trainer, haha.
After checking the relevant information, I found a lot of good open source code for reference. I would like to find SRS, FFMPEG, live555, etc.
Yang, the initiator of SRS, seems to have opened a company named Guan chuangxiang in Bei

Compressed encoded video data output becomes non-compressed color data, such as Yuv420p,rgb and so on; compressed audio data output becomes non-compressed audio sampling data, such as PCM data.

In order to ensure a weekly progress, and because the new version of Vitamio has not been released, decided to postpone the local playback of some features (screenshots, video time, size, etc.), skip directly write the section of the online play part. As you can see from Vitamio's introduction, it supports a variety of network protocols such as HTTP, m3u8, and this chapter will write examples of playing Youku videos.

PrefaceIn order to ensure the progress of each Monday article, and because the new Vitamio version is not released, it is decided to delay some local playback functions (, video time, size, etc.), skip the section that directly writes the online playback part. From the introduction of Vitamio, we can see that it supports multiple network protocols such as http and m3u8. This chapter will compile an example of playing Youku videos.

MPMoviePlayerViewControlle do not recognize Rotation, they are always rendered in the actual size and default direction. There is a solution for MPMoviePlayerViewControlle. The player that the Safari browser calls out should also be MPMoviePlayerViewController, so it cannot identify the direction correctly.
3. MPMoviePlayerViewController controls the video directionYou need additional parameters to determine the video direction, and then rotate the player to play all the videos-mov/mp4/
