It keeps telling me that I should ``GET FLASH'' while I do have ``FLASH 9'' since ages..

Hi Albert,
You need the latest pre-release of the Flash Player 9 Update called 'Moviestar'. You can find it here: http://labs.adobe.com/downloads/flashplayer9.html
It is also version 9, but a newer revision that includes playback of H264 video and full-screen acceleration.
Regards,

Hello Arjen,
Would you mind sending me an email to get me started on adding support for this in my Media Player? My mail is mail [at] jeroenwijering ... com

I've written a little summary about how to implement MP4 Pseudo Streaming in a Flash Player. See: http://h264.code-shop.com/trac/wiki/FlashPlayer

Hi Arjen,
I am writing my own H.264 HTTP-based seek server in Java.
Could you please explin to me which MP4 atoms (aka boxes) you are using to rebuild the MP4 file and split it at the proper seek time offset?
Also, if you could share any of your algorithms for doing so, that would be great.
Thanks,
Jim

Hi Jim,
There is more information on the Wiki (see link in the original mail). You can download and/or browse the sourcecode in SVN. Here's a link for browsing: http://h264.code-shop.com/svn/h264/trunk/lighttpd-1.4.18/src/
The files you are interested in are mod_h264_streaming.c and moov.c
The code patches all the boxes in stbl (stts, stss, stsc, stsz, stco and ctts).
If you have any questions, let me know.

Hi Arjen,
I downloaded the source, built it and have it running on a local server - thanks!
Since the source is not documented, would you please explain the steps that you took in modifying the MP4 atom stuctures to produce the final returned MP4?
Thanks,
Jim

Hi Jim,
Sounds like a good idea. I will start a page on the WIKI with some documentation about the inner workings. I'll keep you posted when I have something for review.

Some of the files I was encoding with ffmpeg/mencoder/x264 were not streaming properly so I took a look at the code to see what was going on (built the source on Cygwin for win32) - it turns out that these encoders use version 1 of the mdhd atom occassionally, which your code currently doesn't support (timescale offset at 20 instead of 12). I was able to add support in, but because of the larger timescale values, many of the data types needed to be changed to avoid overflow. I can send you a copy of my modifications if you want.

Hi Mroizo,
I deleted per accident Arjens comment: we under spam attack ...
Idea: why dont spammers host their owns sites and spam each other
So for now comments are closed
October 24th, 2007 at 06:38 AM Please don't do flash-detection on the example page.
October 24th, 2007 at 02:50 PM Hi Albert, Care to explain? Does it break anything? Thanks,
