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 225kbps bit rate, the definition is terrible. Rmvb has one more VB than R

The client callback function can be used to output the user's original video sample frame data (YUV, RGB): video data callback function

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

Knowledge Point analysis:When a TV user calls to play a video on a USB flash drive, there will be no sound or image or sound. This solution can be used.Procedure:When you watch a USB flash drive video on a TV, there may be sound-free images or images without sound. The specific solution is as follows:1.

. 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

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. F

Author: Hu Zhenyu 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. However, I found that many of my friends are still unclear about s

I said in the last article how to use JNI for H264 encoding, but it's not very practical because of the efficiency problem.
