Originally did a very long time audio and video codec things, should do a summary. Here is about the audio and video coding This kind of work gains and losses and trade-offs, in fact, the main is to give up, there is no reason, right when a listen. Let the readers judge for themselves.Take video coding standard H., thi

usually low, for some information or even no compression effect, without regard to the Code table, Huffman coding compression rate is higher However, in fact, for video compression, the advantages of similar to the compression ratios provided by Huffman coding are far from sufficient, and additional code tables are required. Therefore, in the actual video coding method is used in the exponential Colum

System FrameworkPrinciple Description:Adopt distributed network system, install video client software on mobile phone, install camera Server software on remote server, collect camera real-time video, carry out H264 encoding, and publish it in the form of custom TCP server, and use the client software to enter the IP address of the server. Connect and watch live video.Feature Description:Currently learning v

The project uses video codec, which has been around for the last half a month. To be honest, it has taken a lot of detours and wasted a lot of time. Record your final results here, hoping to help others.

Label: Use SP file code BS algorithm nbsp technology c Video and Audio Encoding/decoding technology: (1) silent FLC (2) audio and visual Avi (3) Both capacity and quality MPEG The quality of MJPEG encoding is quite high. It is a kind of encoding with the highest quality requirement. It is a non-linear system. Therefore, it tries its best to use the jitter algorithm during the Encoding Process (you can also set it to not shake) to simulate the ef

3G video file 3GP codec Library Parse the 3GP file. parse the frame and related information, such as keyframe. Based on the parsed data, you can cut the file according to the original keyframe or the file size. The library contains the splitter and MUX operations on the 3GP file. this frees your company from great pains in the study of the 3GP file, and wins time for the release of your company's product
