Dell Axim and FLV?

[tcox]

Anyone worked with Axims and video? I was under the impression that it would work if I targeted my app for flash 7, which is the version supported by the IE plug-in for the Axim.

I wrote a simple streaming video player using the traditional NetStream/NetConnection methods that works fine when I test it on my Windows PC. The Axim however will only load the sound.

Anyway I know this isn't an Axim forum but I wondered if anyone tried to develop for Pocket PC before and ran into the same issue.

Thanks in advance

Just out of curiosity, does Axim allow you to install FP7 or does it use FL??? and what sort of video does Axim support???

[tcox]

Nope, you don't need fl. It runs 7. I have it installed as an IE plug in but I think there's a standalone player now as well. I'm about to look into that. Pretty sure ou can install fp7 on any device that runs windows mobile 5 or pocket pc 2003 and up.

As far as video on the Axim goes, I don't know too much about it. I thought up until earlier today that it could play flvs... not so sure anymore.

It sounds like that's something you'll have to research more and let us know so that we can help you better...

Well, I figured out the problem. It wasn't the Axim at all but rather the compression codec. I wasn't aware that the format had changed in flash 8, and even though I was publishing for 7 I was still viewing it with 8 on my pc. Re-compressing the video with sorenson fixed the issue. So now I know.

However, a warning! :

Streaming flv content seems to perform _amazingly_ badly on the Axim X51v, even when loading it from the cache. I'm going to experiment with it some. Hopefully the problem can be fixed by optimizing my code, b/c I'd rather not give up on the Axim yet.

Video compiled into swfs seems to run ok, albeit with dropped frames. It's watchable though, and the audio is solid. Loaded flvs on the other hand run at about 3-4 fps with terribly broken audio, even when compressed as hard as possible.

Anyway, we'll see!

Thanks for the info... I am interested in knowing more if you find out more...

That does not surprise me at all. It takes a lot of CPU power to play back compressed/encoded video. If encoding with the older Codec fixed the problem, then the CPU is almost definitly the bottleneck. I'm pretty sure the newer On2 VP6 codec (Flash 8 video) requires more CPU power than the older Sorenson codec. Basically they traded CPU efficiency for better quality and compression ratios.

Edit:

Just to confirm, I found this in the flash Help...

In order to support better quality video at the same data rate, the On2 VP6 codec requires noticeably slower to encode and requires more processor power on the client computer to decode and play back. For this reason, you should carefully consider the lowest common denominator of computer you intend your viewing audience to use when accessing your Flash Video content.

In other words, for handheld devices that don't have the processing power of today's desktop computers, flash 7 video is a better choice.

What dimensions does the video have and what compressions settings are you using? you might actually want to do less compression and make the video smaller in dimension.

[tcox]

You were right. Shrinking the dimensions actually has much more effect than compressing the hell out of it. If I take it right down to about 150x100 it actually plays quite well.

hi,

i am using axim and my swf is embedded within html.

a mp3 file is embedded as stream in timeline and whenever i close the browser(IE) the audio continues to play.

how it happens, even after terminating the swf(+html).

can u?
