vCast and rtsp streaming

Forums:

Hi,

Is there any diffference beween verizon V Cast streaming and rtsp streaming?

VCast streaming works.
RTSP doesn't, well at least not on handsets that is suppose to.
Why? VCast rolled their own for the whole 9-yards instead of depending on IMedia.
I dunno, is RTSP streaming even officially supported by BREW? :mad:

No, it isn't. That's why we keep saying it isn't. ;)

I hear ya.
Max, what about streaming MPEG4 file data via ISource and passing that into IMedia? Would that ever work?
I could get IMedia to play the same file data from file or from a buffer, but never from an ISource or even IPeek... and i'm pretty sure both my ISource and IPeek are good... :(

I know that works for PCM, but I'm not sure about MPEG4. I'd suggest submitting an SR.

As I Know, QTV support RTSP for MPEG4, Right?

Er... read the earlier post. The answer is NO, not officially. :(

To be precise, the answer is that RTSP streaming is not officially supported through BREW. IMedia is just passing the RTSP information down to the QTV engine, but the problem is that neither the QTV engine nor the BREW-QTV interaction is tested during BREW porting evaluation.

Max, is there a way for BREW developers to interact with the QTV engine directly?

Hi Ykhun,
Thanks for the info.

then what is the use of IMedia? for playing only static media files?
but i could able to play on most of the RTSP supported devices, except verizon motorola Razr(V3m & V3c) devices. is there any specific reason?

No, there is not. You have to go through BREW.

That's what happens when something isn't officially supported -- it's not tested and tends to be broken substantially more than the core BREW functionality.

It should on some handsets (and assuming the OEMs turn it on). I believe you may be able to pass in an rtsp: URL to IMedia to play.

It does work, though get it working is little bit of tricky (many OEM mess up the implementation). I have used it in Razr, Krazr and it worked.

There isn't any trick. If it works, you got a nice handset. If it doesn't, you better have your own streaming and software decoding solution in place.

Tirck is to get the implementation correct, dealing with all IMEDIA states correctly.

That's misleading. As I've said, this is not officially supported or testing. "Dealing with IMedia states" is not going to solve all problems.

I'll have to agree with Max on this one. This is misleading. There is NO TRICK. Even if you handle all states religiously, there is absolutely no guarantees it will work. I said this from actual experience on dealing with actual handsets.
Maybe ruben just meant playing around on the emulator... :p
