H.264 video streams are transmitted in NAL units... However, in a nal unit, I-slice (p-slice or B-slice) may be stored, and colleagues may also store other information about the image.Does it mean that I frame, P frame, and B frame extract the VCL information in the received nal unit first, and then classify I, P, and bframe according to the content?However, we can only identify the data type

Therefore, similar code can be transplanted to implement RTSP-over-HTTP in Wis-streamer. However, when oppro live starts a Wis-streamer for each code stream, a total of five Wis-streamer instances are started. If all five processes have RTSP-over-HTTP, isn't it a mess?We look forward to your message!

The synced display of lyrics is added to the android multimedia player. Because the lyrics are directly down on the Internet and are in Chinese. Therefore, the encoding format is GBK, gb18030, and other Chinese character encoding formats. Garbled characters are displayed in Ubuntu. When these LRC are pushed to the SD card for parsing, garbled characters are also displayed.
The solution is as follows:
1. Configure the gedit encoding list. The followin

A simple canvas can be drawn, selected, and saved. Of course, this tool is commonly used in communication software, such as QQ and feiqiu.
Among them, we must listen to the touch events of the fingers. The touch events of the fingers are divided into three types: Press, lift, and move. Usually we only need to press the link, and then the entire finger Sliding Process. Then draw dif

Video-Level Image Rendering on IOS
Image Rendering on ios is typically the drawRect function of UIView. However, this function is asynchronously triggered and executed by the main thread. Although some techniques can be used to achieve the effect of active plotting:
1. Pass the image to the UIView cache.
2. Call setNeedDisplay of UIView to rewrite the re-painting mark.
