means that you do not need to buy expensive DVD ROM and can get the same quality as its video program, and all this only requires that you have a CD-ROM. Playback (decompression) MPEG4 encoding, the requirements of the machine is not high, as long as the CPU is more than 300MHz, and then with 64MB of memory and a 8MB video

Soft Encoding
Hard Coding: By calling the camera recording video that comes with the Android system, it actually calls the underlying HD encoding hardware module, that is, the video card, which does not use the
static screen and can be played using RealPlayer.
Play with software.
The common RM format is the real8.0 format, which uses fixed bit rate encoding. Multiple devices are used in VCD-rm, which has become popular for some time. However, due to the inherent deficiency of the VCD source, it is not clear enough, so the pressure RM will not be clear. Especially Standard online

You can use v4l2 to successfully collect the yuyv video and encode it into H. 264 file, because yuv420 was previously encoded as H. 264 program, so I think yuv422 is encoded into H. 264 is also similar and should be quite simple.
So I am very happy to write the encoding function. Encoding yuv420 I am referring to this article and this blog post. I am now ready to
. That is to say, the collected YUV is written to a file and saved in the form of an interline scan.
If the interleaved check box is not checked, the player cannot play your YUV file normally.
The following figure shows the images normally displayed:
Hey, this is my photo. ^_^
YUV video collection is normal, but videos encoded with x264 are still rendered unsightly !!!
What should I do? Please refer to my next blog titled "yuyv
In the previous article because the USB camera used on the PC can only support Gpeg image format, but the H264 encoding needs to use YUV data, so I found an arm development board to do the test. This thought that the code from the PC to the Development Board is a very simple thing, who knows that because the platform or v4l2 the difference between the bottom of the drive, and finally spent the Dickens to solve the problem. Words not much to say, direc

We just know the CPU frequency, the core number, two cache and other parameters can be, the higher the frequency of high-frequency operation, the core number of the more the better, two-level cache the more about good.
For graphics cards too, we just need to know the graphics card frequency memory and brand, the main frequency is also the speed of the graphics card, the higher the better, video memory is t
I. Preface in the past 20 years, Internet, mobile communication and multimedia communication have achieved unprecedented development and great commercial success. The convergence of mobile communication and multimedia technology is accelerating. research results in network architecture, low-power integrated circuits, powerful digital signal processing chips, and efficient compression algorithms are emerging.

To put it simply, the MKV and AVI formats only encapsulate containers, which encapsulate video streams and audio streams. The container does not affect the image quality. What affects the quality is what is encapsulated in the container. Therefore, changing the container does not affect definition subtitle audio.
I would like to add some basic knowledge about video. Maybe there is something wrong with it.

Recently, many of my friends have asked me some questions about audio/video encoding and decoding. This is probably because of the popularity of mobile phones, PDAs, and other devices and the increase in bandwidth, the spread of audio and video is becoming more and more popular.
