1, open the encoder, set the code frame parameters Profile@level, according to the needs of the direct choice of 720p or 1080p, etc. on the line. 2, the following encoding type (Encoding type) is more important. First is single, which is the simplest type of encoding, with the advantage of being fast, but with the same compression rate per frame, which can be wasteful or inadequate. In general, this is enough, choose Single Pass mode, the followin

Record Cool The settings in the Encoder window will directly affect the video's quality, sound and bitrate. Video size: If you want to record HD video, just select "HD Mode", one of the "original quality" is the best, but the resulting file and network code flow will be the largest, "super clear quality" slightly less clarity, but a small half of the file, fluency will also be much higher, you can choose 1/2 size, will be recorded in half the size;

The basic description of speex includes a command line encoder and decoder. these tools generate and read the speex files packaged in the Ogg container. although it can encapsulate speex in any container, Ogg is recommended as a file container. this section describes how to use the command line tool for the speex file of Ogg. 4.1 speexencThe speexenc unit is used to create a speex file through a raw PCM or wave file. You can use the following command:

close to an envelope. That is to say, the "best preset" is not affected by the video content (of course, there is still a little bit, but the degree is not big ). This report uses the "bus" test video sequence experiment results. Summary This report uses four methods to analyze the x264 option:1. Use convex hull to analyze the optimal option. 2. Use the "color Cloud Chart" to analyze the option. This method is simple and intuitive, but cannot be accurately quantified. 3. Use Lambda paramete

Refer to the following article:http://blog.csdn.net/a992036795/article/details/54286654First, prefaceAs I said in the previous article, I used libx264 to encode video h264 very inefficiently, because libx264 uses soft coding. So I searched online to learn that using the system API can hard code video, thereby reducing the pressure on the CPU, to improve the efficiency of the role. I wrote a demo and tried it, and it was obvious that efficiency was improved.second, the idea1. Core class Med
