copied!<p><strong>UPDATE</strong></p> <p>so apparently, even though the server signals it accepts range requests (with the <code>Accept-Ranges: bytes</code>), it does not actually do so. to see if there is another way to make the flv seekable, let's have a look at the communication between flash player and server (i use <a href="http://www.wireshark.org/" rel="nofollow noreferrer">wireshark</a> for this):</p> <ol> <li><p>the request when starting the player is:</p> <pre><code>GET /files/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx/ HTTP/1.1 Host: xxxxxx.megavideo.com <some more headers> <no range header> </code></pre></li> <li><p>this is answered with a response like that:</p> <pre><code>HTTP/1.0 200 OK Server: Apache/1.3.37 (Debian GNU/Linux) PHP/4.4.7 Content-Type: video/flv ETag: "<video-id>" Content-Length: <length of complete video> <some more headers> <the flv content> </code></pre></li> <li><p>now when i seek in the flash player, another request is sent. it is almost the same as the initial one, with the following difference:</p> <pre><code>GET /files/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx/8800968 HTTP/1.1 <same headers as first request> </code></pre></li> <li><p>which gets answered with a response almost the same as the initial one, with a difference only in the <code>Content-Length</code> header.</p></li> </ol> <p>which lets me assume that the <code>8800968</code> at the end of the request url is the "seek range" (the byte offset in the file after seeking) we are looking for, and the second response <code>Content-Length</code> is the initial <code>Content-Length</code> (the length of the whole file) minus this range. which is the case indeed.</p> <p>with this information, it should be possible to get what you want. good luck!</p> <p><strong>UPDATE END</strong></p> <p>this will only work if the server supports <a href="http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.35.2" rel="nofollow noreferrer">HTTP RANGE requests</a>. if it does, it <a href="https://stackoverflow.com/questions/1538952/retrieve-partial-web-page/1539084#1539084">will return a 206 Partial Content response code with a Content-Range header and your requested range of bytes</a>. check for these in the response to your request.</p>
