Download and install FFmpeg ./configure--enable-libx264--ENABLE-GPL--enable-sharedMakeMake install 2. Use the installed ffmpeg with the command to encode YUV as.

Recently, I am working on an online tutorial Network project. I need to upload videos in any format to automatically play h264 standard videos using html5. Finally, PHP + FFMPEG is used for implementation. Here we will share our detailed solutions with you! Configure the php. ini file The Code is as follows: File_uploads = on; // whether to allow file upload over HTTP. ON is enabled by default.Upload_tmp_dir; // upload the file to the place where

Php+ffmpeg implements the automatic transcoding of video into H264 standard MP4 file, Configuring the php.ini File File_uploads = on;//whether to allow the switch to upload files over HTTP. The default is on is open upload_tmp_dir;//File upload to the server where temporary files are stored, if not specified will be used the system default temporary folder Upload_max_filesize = 1024m;//Wang Wen Business, that is, the maximum size allowed to upload fil

H264 is a new generation of coding standards, high compression high-quality and support a variety of network streaming media transmission is known, in terms of coding, I understand his theoretical basis is: reference for a period of time, the statistical results show that in several adjacent images, there is generally a difference in pixels only 10% of the points, The difference in brightness does not change beyond 2%, and the chroma difference is onl

Have such a demand, give you a h264 raw data file, let you play directly out, how to implement?The idea is that the H264 raw data format is 0x00000001 back with 0x67 0x68 0x65 0x41 Such data, decoding requires a complete NAL data unit, We need to read the data from each 0x00000001 and the next 0x00000001 before decoding it to the decoder.Read the file I will not wordy, this article mainly explains how to ob

RTP h264 PS MPEG-2 Preface: RTP analysis. I found a lot of information on the Internet, but it was not complete. So I tried to make a comprehensive analysis, I have referenced many articles and listed them at the end of the article. I would like to express my gratitude. The development of the Internet is inseparable from the selfless dedication of everyone. I decided to start from me and hope everyone can support it. Original is not easy, reprint Ple

1. Macro Block matching pixel precision: In MPEG2, the motion estimation accuracy is 12 pixels, which can be implemented through linear insertion (which may be simply corrected ); both H264 and MPEG4 support 14-pixel precision. 2. Number of reference frames: MPEG2. P frames of MPEG4 can only have one reference frame, and B frames can have two reference frames. H. 264 can have up to 15 reference frames, one 1. Macro Block matching pixel precision: In M

IVideo Encoding 1.1 target of video compression and encoding 1) Ensure compression ratio 2) Ensure recovery quality 3) easy to implement, low cost, and reliability 1.2 starting point of compression (feasibility) 1) Time Correlation In a video sequence, adjacent two adjacent frames have very few differences. This is the time correlation. 2) Spatial correlation In the same frame, there is a large correlation between adjacent pixels. The closer the two pixels are, the stronger the side correlation

Recently I want to upgrade my TV, so I want to buy a 46 (47) TV. I have locked several models on the Internet. Today I went to Suning and Dazhong and Gome to see the actual results, I would like to share with you that everything is my subjective feeling and the feeling of a batch of prototypes I have seen. So only one reference is provided. Source of the test: 1. 720 p MKV format x264 embedded subtitle cartoon aptx Conan. 2. h264 1080 p Deep Blue 3,

If you want to transmit video streams in real time when using Android phones for h264 hard encoding, you need to know the sequence parameter sets (SPS) and picture parameter set (PPS) of the video stream ). Today, I understand how to obtain SPS and PPS. I will record them here. I hope you can get some help here. First, let's take a look at the prerequisites. The video recording parameters I set are: Mmediarecorder. setoutputformat (mediarecorder. outp

I wrote an article earlierArticleAnalysis of the format of using RTP for h264 packets: RTP encapsulation of h264. However, it seems that the split and some situations that need attention are not clearly stated, so here we will make a supplement and also serve as our own memo (I don't seem to have a good memory ). note that the sampling rate of h264 is
