Nice to see that the code is being picked up and used. :)

Just to keep you updated, there are now also plugins available for Apache and Nginx (next to Lighttpd).

Let me know if you have any feature requests, we’re always looking to improve on things.

@Arjen: The code is excellent and is essential for a website I’m working on so, thank you!

Hello, the problem is in your flashvars line (the script that I used at the demo site could not have worked for you since it uses a slightly modified version of the original player).

In the original form of the player (the SWF you have on your site) the player only sends the correct requests to psstream if it has the “streamer=lighttpd” parameter passed in the flashvars; the mp4 file path is then sent through the id parameter (i.e. “streamer=lighttpd&id=video.mp4″).

Please see the section marked above in red (in the post) to understand the issue, it is all explained there in detail.

Please tell me if you need more help, I’ll be glad to pitch in :D.

many thanks for your work!

Can I ask you if the parameter settings for mp4 pseudostreaming (as given above) is still deemed to be correct:
s1.addParam(”flashvars”,”image=preview.jpg&file=http://mydomain.com/psstream.php&type=video&id=video.mp4&streamer=lighttpd”); ?

I tried many different combinations of this bunch of parameters but I never got it to work properly (with version 1.0 (beta) downloaded yesterday). Sometimes the video started but the pseudostreaming seek functionality never worked.

I then had a look at the source code of your demo and with some minor changes I managed to get it to work both with the JWPlayer embedded in Flex and the standalone version (embedded in HTML via swfobject):

Flex:

private var file:String = “player.swf?file=kanea_maa.mp4&” +
“streamer=http://192.168.193.129/psstream.php?id=kanea_maa.mp4&” +
“controlbar=over&” +
“resizing=false”;

HTML:

var s1 = new SWFObject(’flash/player.swf’,'player’,'400′,’300′,’9′);
s1.addParam(’allowfullscreen’,'false’);
s1.addParam(’allowscriptaccess’,'always’);
s1.addParam(”flashvars”,”file=kanea_maa.mp4&streamer=http://192.168.193.129/psstream.php?id=kanea_maa.mp4&image=img/annex-icon.gif”);
s1.write(’preview’);

I’m using XAMPP (-> Apache 2) in an ubuntu vmware image as pseudostreaming solution.

Cheers, Thomas

It seems only JW FLV Player supports this type of h264 pseudo-streaming.

psstream_flv and psstream_mp4 do not work when attempting to load the files through Internet Explorer over SSL (https).

I am guessing its a header issue. Presuming that these plugins output headers? I’ve tried using PHP to output proper headers before calling psstream plugins, but to no avail.

I can use xmoov-php pseudo-streaming script (basically php file-seeker) for FLV files and it works fine over SSL in IE. As soon as I switch to psstream_flv, IE fails to work over SSL. In JW Player, error comes back as “video not found”

Did you try using psstream_flv without SSL? Have you made sure the player send the correct parameters to psstream? Read the section in red displayed above carefully.

I have this structure:

myhost.com/mediaplayer/psstream.php
myhost.com/mediaplayer/predator.mp4
myhost.com/mediaplayer/index.php (where the player actually is running)

I’ve check and everything is reachable from the outside (internet) and the psstream module is working !

Refering to the demo and the howto, I tried the following configurations :

s1.addParam(”flashvars”,”file=predator.mp4&streamer=http://myhost.com/mediaplayer/psstream.php”);
-> ERROR: Video not found predator.mp4

s1.addParam(”flashvars”,”image=predator.jpg&file=http://myhost.com/mediaplayer/psstream.php&type=video&id=predator.mp4&streamer=lighttpd”);
- > ERROR: Video not found http://myhost.com/mediaplayer/psstream.php

Can you help me please ?

So I modified psstream.c adding the variable tsrm_ls.
line 123 : sapi_header_op(SAPI_HEADER_ADD, &psstream_sapi_header_line, tsrm_ls);
line 128 : sapi_header_op(SAPI_HEADER_REPLACE, &psstream_sapi_header_line, tsrm_ls);
line 130 : #define SEND_HEADERS sapi_send_headers(tsrm_ls);

And now it compile fine, spend couple hours so if it can help anyone.

This looks like a great piece of work and I would like to modify it so that I can use it with my cutom Flash Player and shared windows hosting account.

The shared hosting thing means I suspect that I can’t instal it as an extension as per your process.

What I think I can do is create an extension as a .dll and store it in a an extensions path on my server (and point to this path in my PHP.ini).

I am about to embark on this voyage of discovery .. any help would be appreciated (and If I get there I will post the results back here).

First peice of help would be .. Am I on the right track, and is it possible?

If so what aspects of the current code should be dropped?

What will have to be added?

Thanks

Jim

There is a problem though, as far as I can tell, the real issues that usually make code incompatible between Windows and Linux are things like low/level routines, I/O, access to hardware and so on.

The problem is that psstream uses moov.c (from Cinelarra project) which is the really the smart bit of the whole thing, and which does a lot of complex file I/O.

So, although I am unfamiliar with porting PHP extensions to Windows, I don’t think this is the real problem. You should first check if the moov.c file contains any operations that are incompatible with Windows (or maybe missing).

I’m really sorry I can’t help further with this.

i have been really busy on other stuff of late, but hope to get back to this next week and will check out windows moov.c

Thanks again for the heads up.

Jim

Thanks a lot for your excellent work firstly, I have tried to find this kind of library for several days. But I still have some problem when playing flv or mp4 files, it reports “file not found” error. Besides, I also want to confirm whether this library can support streaming of both normal FLV and FLV with H264?

Thank you again!

Thanks for this php extension but,
Can you write this directly in a php class (without ext) ?

Regards, bernedef.

I think the best scenario would be to have a separate streaming micro-server that would wrap the h264 parsing functionality and would only serve mp4/flv files. This is quite doable, and I intend to make it happen quite soon (because I need it).

I agree that the PHP extension is a bit awkward to compile and use; it also uses more memory and is slower since it implies that the whole PHP virtual machine must be started for streaming to be done. The micro-server would be faster, lighter and a lot safer to use.

Do you know if peteava.ro is using your extension or.. something else?
i like how it’s working on big files so i’m wondering what are they using because personally on my tests the code-shop method in nginx/lighttpd gave me few times the i/o wait of usual downloads under some load..

multumesc.

I have tried too with:
so.addVariable(”file”, “‘http://myurl/psstream.php?id=/mypath/video.mp4″);
and
so.addVariable(”id”, “/mypath/video.mp4″);

and nothing… it dont work.

Yes, I have added:
so.addVariable(”streamer”, “lighttpd”);

Any help? Very thank for this script, i will can protect access to my video files now! :)

I installed the module and is working fine with mp4 video files. Then I tried with an AAC file and the resulting data is not recognized by VLC player.

This is how I tested it:

1) Test original AAC file (40 seconds long) with VLC in my workstation
2) Upload file to my test web server
3) wget “http://192.168.0.41/test/psstream.php?id=music.mp4&start=10″
4) Download resulting file to my workstation and test with VLC. VLC does not play it

File was converted from WAV with Nero AAC Encoder in variable bit rate mode (-q 0.15)

Is it possible to use this fantastic module with AAC files?

ffmpeg -i music.aac -acodec copy -f mp4 music.mp4

Then, change the MOOV position with

qt-faststart music.mp4 musicOK.mp4

Now, you can access musicOK.mp4 via http pseudostream.

Thanks!

i will soon make this thing ready for ClipBucket ;)

Maybe you could then provide your users with a professional/commercial version of the ClipBucket services based on L/S-2.0.

Cheers,
Andrei

do you know if your php extension also works together with flowplayer (www.flowplayer.org) and the flowplayer pseudostreaming plugin? http://flowplayer.org/plugins/streaming/pseudostreaming.html

and what would then be the correct syntax to call your php extension?

thanks very much!

Tom

everthing works fine for me, but if I jump to a certain position via “&start=” there’s no sound. Without offset sound is fine. I’m using h264 with ACC. Any ideas?
