various efficient compression and decompression algorithms makes it possible to transmit multimedia information over the network. Network Video Monitoring is widely used in many occasions with Its intuitive, convenient, and rich information.
Figure 1 Network Video Monitoring System Structure
The network video monitoring system is a system based on the client/server model. It consists of a video server and a client. The Video Server is an embedded system consisting of saa7113, pnx1301, and rtl
% (especially on high bitrates ). cabac (as cavlc) is a lossless method and therefore will never hurt the quality, but will slow down encoding and decoding.
Loop/deblocking filter:In contrary to prefiltering (for example via avisynth, done on the input), or postprocessing/filtering (via the decoder, done on the final output ), loopfiltering is applied during the Encoding Process on every single frame, after it got encoded, but before it gets used as r

In 2013, Nal Kalchbrenner and Phil Blunsom presented a new end-to-end encoder-decoder architecture for machine translation. In 2014, Sutskever developed a method called sequence-to-sequence (seq2seq) learning, and Google used this model to give a concrete implementation method in the tutorial of its deep learning framework tensorflow, and achieved good results (see https:// WWW.TENSORFLOW.ORG/TUTORIALS/SEQ2SEQ).

HOWTO 1:build a sample audio graph.Initialize Mediastreamer2When using Mediastreamer2, your first task was to initialize the library:# #include int i;I=ms_init ();if (i!=0)return-1;MEDIASTREAMER2 provides internal components which is called filters. Those filters must be linked together so, OUTPUT from one filter was sent to INPUT of the other filters.Usually, filters is used for processing audio or video data. They could capture data, Play/draw data, Encode/decode data, mix data (conference), T
Let's take a look at the name of the decoder in the Android system, and the soft decoder usually starts with omx.google. A hard decoder is usually a OMX. [Hardware_vendor], such as TI's decoder is the beginning of omx.ti. Of course, there are some non-compliance with this naming convention, not to OMX, it will also be

The PES package consists of Baotou and payload , and the specific format is summarized as follows:You can see that Pts/dts is in the PES package , and these two parameters are the key to resolving the video-Audio synchronization display , which prevents overflow or underflow of the

In digital TVs, all information and signals, including videos, audios, texts, and images, are converted into data after being digitalized. Data should be packed according to the relevant standard (usually MPEG-2) before transmission, forming fixed length transfer (TS) packet, the MPEG-2 TS packet length is 188 bytes, and then quickly transfer to the destination through the network. If there is no boot inform

VLCThe full name is video LAN client, which is an open-source, cross-platform video player. VLC supports a large number of audio and video transmission, encapsulation, and encoding formats. For a complete list of features, see http://www.videolan.org/vlc/features.html. The following provides a concise example:Operating Systems: Windows, WinCE, Linux, MacOSX, BEOs, and BSDAccess format: file, DVD/VCD/CD, HTTP, FTP, MMS, TCP, UDP, RTP, IP multicast, IPv6, RTSPEncoding formats: MPEG
Decoding process of TS Stream-ES-PES-DTS-PTS-PCR
TS Stream decoding process:
1. Get Pat in ts
2. Obtain PMT From ts
3. You can know the video (audio) type (h264), corresponding PID, and pcr pid transmitted in the current network based on PMT.
4. Set the video filter of the Demux module to the PID and stream type of the corresponding video.
5. the payload data in the ts data packet obtained from the video Demux filter is one piece of PES. The ts header contains the number of packets about whic
accordingly, which are differentiated by specific factory names. For example, the following code obtains a factory object named Mad through the Gst_element_factory_find () function, which can then be used to create a corresponding MP3 decoder component:Gstelementfactory *factory;factory = Gst_element_factory_find ("Mad");Once the factory object has been successfully obtained, it is then possible to create a specific Gstelement object by using the Gst
