[转]Iphone m3u8 segmenter from ffmpeg for video streaming

源地址：http://lukasz.cepowski.com/devlog/30,iphone-m3u8-segmenter-from-ffmpeg-for-video-streaming

Recent versions of ffmpeg contains a m3u8 segmenter feature which can be used for remuxing video files for streaming over http and watching video on iphone. 

Segmenter feature usage for iphone

Let's say that there is some .ts media file encoded with mpegts codec and we want to segment it for streaming over http. Segmenting is a process where one media container is being converted into set of smaller files with different quality to adjust the current quality to the bandwidth between streaming server and the display, iphone in this case. Segmenter will produce a set of smaller .ts files and a "playlist" .m3u8 which contains urls of the .ts files.

To process media by ffmpeg builtin segmenter run:

 
ffmpeg -re -i source.ts -codec copy -map 0 -f segment -segment_list foo.m3u8 -segment_list_flags +live -segment_time 10 out%03d.ts
 

It will produce .m3u8 playlist and .ts files with segments.
Note that this command will not transcode the video, it will just split data. Source .ts file should be encoded with mpegts codec in order to play it on iphone.

Compile static version of ffmpeg

Following steps are required to build stable static version of ffmpeg-1.0. Tested on debian i386 and amd64.
