Reason: mp4 appears to be a patented AV format. Node-webkit do not support it ... It seems to be. Workaround: Install the Chrome browser locally, install the directory (example: c:\Google\Chrome\Application\37.0.2062.103), and locate the Ffmpegsumo.dll file. Copy (Ffmpegsumo.dll) and replace the Ffmpegsumo.dll in the Node-webkit directory. Note: Since the chromium version is numerous, the chromium version of the downloaded Chrome browser will be c

, for example, I want to turn the original video code rate nearly 20000, my hard drive brother said this is too high, so I sacrificed some of the quality of 6000, the general turn anime words 1000-2000 enough. Bit rate pattern: average bit rate and 2 times coding is my common two modes, 2 times coding quality is better than average mode, but time consuming probably increases about 30%. (HD recommendation 2 times code) 5, Step 5 set Audio parameters Audio format and encoder you can

This example describes how PHP uses Memcoder to turn video into a MP4 format. Share to everyone for your reference. The implementation methods are as follows: Copy Code code as follows: ConvertTo ("Some-input-video.avi", "Output.mp4"); function ConvertTo ($input, $output) { echo "Converting $input to $output $command = "MEncoder $input-o $output-af volume=10-aspect 16:9-of AVI-NOODML-OVC x264-x264encopts bitrate=500:level _IDC=41:BFRAMES=3:F

This article illustrates how PHP implements a video to MP4 and get a video preview. Share to everyone for your reference.

FFmpeg has very powerful features including video capture, video format conversion, video capture, video watermarking, etc. The use of these features on the Internet is mostly based on the command line. This is not conducive to our in-depth study of customized FFmpeg, in the future I will write a series of code to implement these features of the tutorial for everyone to learn. The first part of this series I am going to write on the implementation of Windows, after the partial write porting to A

http://blog.csdn.net/gavinr/article/details/7183499 1. Get data ffmpeg read the H264 data in MP4, and do not directly get Nalu, the file does not store 0x00000001 separator. The following figure is the data in Packet.data As you can see from the diagram, there is no delimiter (0x00000001) at the beginning of the data in packet, nor is it 0x65, 0x67, 0x68, 0x41, and so on, so it is certain that this is not a standard Nalu. In fact, the first 4 charact

Code stream encapsulation using open Source Library FFmpeg The H264 stream is written to H264 buffer via the function h264buff_write (), and mux_thread the received stream into the MP4 file. Here I use a separate thread encapsulation stream is to solve the recording process of the cycle of the problem, or can not be separate pull thread.

How to play the rmvb mp4 mkv video file in Fedora 22? This is a problem that occurs after the Fedora system is installed. There is a tutorial on how to solve the problem of playing rmvb video in Fedora 21 on the Internet. In fact, Fedora 22 is also applicable, but Fedora 22 changes Yum to dnf, so you only need to change the command. Simply install the rpmfusion source. Sudo dnf install -- nogpgcheck http://mirrors.163.com/rpmfusion/free/fedora/rpmf
