Streaming video file?

Question

Hi I need to stream flv file. streaming should look like live streaming. and I their should be a way to change target file. sorry for my poor English.

Answer 1

If by "streaming" you mean "showing a flash-video clip", flv-streaming isn't really streaming, but it's a normal file transfer, with the flash player starting playback even if the file isn't completely downloaded to the client. Time seeking is implemented in a standard HTTP way, with a file download offset - if you scroll the video halfway on the timeline and it hasn't downloaded yet, the current download is (most often) aborted, and restarted with an offset of filesize/2 bytes.

So, you could be fine with just using plain old readfile() and fixing the HTTP mime-type headers appropriately with header(). But, since you'd need seeking, you need to parse the HTTP request and instead of readfile(), use fpassthru(), seeking the right place, instead.

tl;dr: Avoid handling this on the PHP side, and let Apache (or the httpd of your choice) handle this instead.

I'm not quite sure what you're asking about, but if you have a bunch of media files and want to play them with a Youtube-esque media player on your website, I suggest checking out Flowplayer - It has an amazing Javascript API that lets you do all kinds of cool stuff to the player, including handling stuff like playlists and programmatically changing the current video.

I recently used it on a project with great results.
