an HTML document, tags are modified to, in fact, in the decoding of the HTML body of these tags to be modified to point to the decoded image of the specific path. However, given the specific decoding process for the image will be different processing, so in this decoding class, the HMTL body of the label is not modified. So in the actual use of this class, for the image of the HTML text, but also need some processing. The picture in the body can be saved with temporary files, or it can be saved
: 122223443556dsdf @ ntsever is added to its MIME header. 122223443556dsdf @ ntsever is a unique identifier. In the HTML document, when decoding a tag, you also need to modify the tags in the HTML body to point to the specific path of the decoded image. But considering the specific decodingProgramThe image is processed differently, so the labels in the hmtl body are not modified in the decoded class. Therefore, when using this class, some processing is required for HTML text with images. Images
the performance issue. Currently, the CPU clock speed cannot withstand high bit rate decoding.
1. Solve the problem of preventing CPU block first. When the CPU time slice is tight, the buffer pool is full and is sensitive to the priority setting of the filter! Demux must be of the highest priority; otherwise, you will not be able to play it later. Let's look at the following filters connection diagram. It should be said that it is the most prototype filter of the player.

After the factory object is obtained successfully, you can use the maid () function to create a specific ststelement object. This function
There are two parameters for calling: The factory object to be used and the name of the component to be created. Component names can be obtained through queries, or factory pairs can be generated by passing in a nu

We are off Part 1 by passing a value (0, 0) to our trained decoder (which has 2 neurons in the input) and finding its out Put. It looked blurry and didn ' t represent a clear d

Pipe
Contains a read and a written channel (Pipe.sourcechannel and Pipe.sinkchannel), which channel can be used for communication in the process.
FileChannel
Used to read, write, map, lock and so on files. The class associated with the mapping operation has Filechannel.mapmode, and the class associated with the lock operation has filelock. It is wor

customization, for familiar with the netty of the implementation of the bottom of the developers, directly based on channelhandler expansion of development, not very difficult. But for most beginners or users who are unwilling to understand the underlying implementation details, they need to provide them with simpler class libraries and APIs rather than Channelhandler.
Netty has done a very good job in this area, for the codec function, it provides a common codec framework for users to expand,
MPEG2 systems.
ES is a data stream directly from the encoder. It can be a collectively referred to as an encoded video data stream, audio data stream, or other encoded data streams. The es stream is converted to the PES package after it passes through the PES package. The PES package consists of a packet header and payload. The specific format is as follows:
We can see that PTS/DTS is in the PES package, and the two parameters are the key to solving synchronous display of video and audio and p
will share with you how to build a modern player and what key components are needed to build such a player. Generally, a typical player can be divided into three parts: UI, multimedia engine, and decoder, as shown in 1:

receiver is decoded. It can also avoid the overflow and underflow of the decoder's input buffer.When designing a video sending system, it is particularly important to precisely control the bit rate of the MPEG-Ⅱ transmission stream. When MPEG-Ⅱ groups are directly transmitted, the system time control is relatively simple. The key issue is how to accurately calculate the input time of the video source. If this problem is solved, the decoder-side decod
