The features of high compression ratio standards provide a broad space for technicians to strike an optimal balance between complexity, latency, and other factors that constrain real-time performance.

Running result
Program input is a YUV file (two formats, YUV444P and YUV420P, have been tested ).
The output is an H.265 code stream file.
x264_picture_alloc.The structure of the stored data is as follows.X__picture_t: stores pre-compression pixel data.X1__nal_t: stores compressed encoded bitstream data.
The flowchart also contains a "flush_encoder" module, which uses the same functions as the encoding module. The only difference is that no video pixel data is input. It is used to output the remaining bitstream data in the encoder.

After finding the compatibility problem on the internet, you need to right-click the format factory Program-> properties-> compatibility, and select "Disable desktop elements" to display the icon properly. Main Interface.
Click the icon on the right to add tasks in batches.
From the options in the format factory, we can see that many options are to configure various command line encoders. The configuration page shown in H.264 is actually the x264

Expression family of products that can be used to create compelling user interfaces for Web and desktop applications. Expression Encoder also offers free and paid editions. The paid edition is included in the Expression Studio 3 Suite (USD 599) and the Expression Web 3 Suite (USD 149). The free download version does not support encoding into Silverlight Smooth streaming or H.264 video, nor does it support
What is a video encoder?
Video encoders, also known as video servers, enable an existing analog CCTV video surveillance system to be integrated with a network video system. video encod
This article introduces a simple Video Encoder Based on FFMPEG. The YUV420P pixel data is encoded as H.264 compressed data. The code of the encoder is very simple, but every line of code is very important. It is suitable for a good study. After the code is clarified, the encoding process of FFMPEG is basically clarified. At present, although I have already comple

My blog tells about WMS9, can implement streaming media server, but without WME (Windows Media Encoder) support, always feel the lack of something, Here's how to get the device video audio stream through the. NET implementation WME and push it to remote (of course, local) streaming media broadcast publishing point.
First, download the WME9 SDK, installation completed: This step is to experience the main WME
