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)

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. The implementation methods are as follows:
Copy Code code as follows:

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

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.

In fact, SVN manages the source code in units of behavior, that is, if the two programmers do not modify the same program, SVN automatically merges the two changes. If the row is the same, SVN will prompt the file confict, conflict, You need to manually confirm.

learned from GitHubHow to write code.
Fortunately, GitHub was unblocked soon, but what if it becomes "a well-known foreign website that cannot be accessed" in the future? So I recommend some code hosting servers that support Git for your selection. In fact, in addition to preventing GitHub from becoming inaccessible for a long time, there are other reasons for choosing a website other than GitHub. For example, GitHub mainly supports open-source proje
Factors affecting data center hosting
With the advent of the big data era, a large amount of data to be processed is migrated to cloud computing. Some may say that data center hosting will gradually die out. However, many experts in the technology industry believe that data center hosting is only slightly different, but also plays an important role. As companies
