Courses

Notice: The series of courses in the tight recording update, please pay attention to. To: the series of courses related to: FFmpeg, WebRTC, SRS, Nginx, Darwin, Live555, and so on. Including: audio and video, streaming media, live broadcasting, Android, video surveillance 28181, and so on.

I'm going to walk you through: capturing the microphone, PCM resampling, encoding AAC or MP3 audio for storage, and live streaming.

Specifics include:

1. FFmpeg captures the microphone and stores it as PCM.

2.PCM resampling principle and practice.

3. Capture the microphone and transcode AAC or MP3 in real time and save the file.

4. Capture the microphone and real-time transcoding AAC and can be live.

Audio-video and streaming media is a very complex technology, involving a lot of concepts, principles, theories, many beginners do not learn the basic theories, but directly to do the project, often see the code of c/c++ confused, do not know what the code actually means, why is this?

Because of not learning the basic theory of audio, video and streaming media, it's like learning English, not learning the basic words, but listening to the English news every day, and you can't always understand it.

So what, you must seriously study the basic theory, and then learn the player, transcoder, non-commercial, live streaming media, video surveillance, and so on.

Mr. Mei has been engaged in the audio/video and streaming media industry for 18 years; he has worked in companies such as YongxinVision, Zhongke Dayang, Baidu, and Harris Broadcasting Division of the U.S., and has rich experience; he has personally led the full set of projects of broadcasting live broadcasting and is well versed in h.264/h.265/aac, and he has participated in the practical products such as the web page player on Baidu's app personally.

Currently, he is a self-employed entrepreneur, mainly focusing on the audio/video + streaming media industry, proficient in audio/video encryption, streaming media online transcoding and fast editing and other popular products.
