nginx搭建基于http协议的视频点播服务器

阅读更多关于 nginx搭建基于http协议的视频点播服务器

1，于由自己的服务器上已经安装好nginx(具体安装方法见我的另一篇文章，Linux中安装nginx)，所以不再安装。 2，下载nginx_mod_h264_streaming-2.2.7.tar.gz(自己在网上搜吧)。 3，安装pcre，先看有没有安装。 [root@localhost vsftpd]# rpm -qa pcre pcre-7.8-7.el6.i686 已经安装(上篇加rtmp模块的时候已经安装了) 4，解压nginx_mod_h264_streaming-2.2.7.tar.gz，添加flv，mp4模块。解压到和nginx源码同级的目录。然后./configure --add-module=../nginx_mod_h264_streaming-2.2.7 --with-http_flv_module --with-http_mp4_module 因为flv 和http是nginx自带的所以不用下载这个模块。 5，make 可能遇到问题1 /root/nginx_mod_h264_streaming-2.2.7/src/ngx_http_streaming_module.c: In function ‘ngx_streaming_handler’: /root/nginx_mod_h264_streaming-2.2.7/src/ngx_http

Media Foundation IMFSinkWriter::Finalize() method fails under Windows 7 when muxing H.264 frames into MP4

阅读更多关于 Media Foundation IMFSinkWriter::Finalize() method fails under Windows 7 when muxing H.264 frames into MP4

问题 I'm writing a tool in C# that muxes H.264 frames into MP4 files, and I'm using Media Foundation's media sink with sink writer to do this. Things work pretty well under Win8, but under Windows 7 the same code throws an exception, HResult: 0xC00D36E6 (MF_E_ATTRIBUTENOTFOUND), when invoking sink writer's Finalize method. As a result, the generated MP4 file is not properly closed, and is (of course) not playable. The mftrace log shows that the failure under Windows 7 occurs somewhere after (or

How can I turn a series of images into a video using JCodec?

阅读更多关于 How can I turn a series of images into a video using JCodec?

问题 I'm trying to use JCodec to turn a series of images into a video inside of a Java SE desktop application. The few methods I've tried all resulted in a video that Windows Media Player could not play. It is unclear to me if this is a codec issue (doubtful) or if I'm not creating the video properly. When I try to play the video in Windows Media Player I get: Windows Media Player cannot play the file. The Player might not support the file type or might not support the codec that was used to

Why is PHP interfering with my HTML5 MP4 video?

阅读更多关于 Why is PHP interfering with my HTML5 MP4 video?

问题 I'm writing a web app that serves H.264 encoded MP4 video. In Chrome and Safari, it does this via an HTML5 video tag. In order to control access to these videos, their contents are served via PHP using a really simply mechanism: header('Content-type: video/mp4'); readfile($filename); exit; No matter what I do, the videos will not stream. Additionally: If I change the source code to serve the files directly, using the same video tag but linking to an Apache-served copy of the video with no PHP

Can you set an arbitrary byte offset in the mp4 header for the first frame?

阅读更多关于 Can you set an arbitrary byte offset in the mp4 header for the first frame?

问题 TLDR: Can you set an arbitrary byte offset in the mp4 header for the first frame? I have an idea for a utility program to work with mp4 files that have been recorded on a goPro, to assist in later time aligning of concurrently recorded files. at the core of the idea is to take a large file (multiple gigabytes), and stream through it frame by frame from the start, until a frame with an embedded QR code is found, which would have been shot by pointing the camera at a smartphone or tablet, which
