流视频php

I am trying to get my php video handler file to serve up videos and am testing it on the file handler page itself without luck.

Weird behaviour: A window just pops up asking me if I want to download the file, even if I delete the readfile(). If I change video/x-flv to video/flv then a player loads in my window but the file does not play. Also if I take away that header all together my browser crashes.

I figured this script should place the video in the browser at the least and have it be playable in the browser if I am testing the file directly with the browser. The file path is correct after the query... Also the file is outside of my web directory but I don't think that should matter because I can serve images outside the directory successfully using a similar script. Anyone have any ideas?

$sql="SELECT file_name FROM video WHERE vid_id=?";
$stmt=$conn->prepare($sql);
$result=$stmt->execute(array($ID));

while($row = $stmt->fetch(PDO::FETCH_ASSOC)){
$file_name = $row['file_name'].".flv";
}

$path="/home/g/Desktop/processed/".$file_name."";


//check if image is readible and type
if (is_readable($path)) {
header('Content-Length: '.filesize($path)); // provide file size
header("Expires: -1");
header('Content-Type: video/x-flv');

$content=readfile($path);


}
else {
error_log("Can't serve video: $file_name");
}

Streaming doesn't work like that.
To have a proper streaming you need to use a Player like: http://flowplayer.org/

If you just send the content of the video, the browser will pop up the save dialog

I was unable to use php to pass videos to OS player. I switched to flow player and things are working.
