Hi all Has anyone been successful in using Samuel Vinson's port of the G729 codec for windows mobile? Any help is much appreciated. Regards Jerry

Didn't try with the Samuel's instruction, but I've done with voiceAge Library. You can check it on the pjsip archive.

Yeah, the big problem with the VoiceAge library is that its an unreasonably expensive piece of software, I'm sure its good but I'm at a loss to see how anyone could make a profit using it, considering the small marketshare the winMo phones have for apps. If a G729 iphone app can reasonably be expected to make around $150 a week less about $110 for patent licencing fees , then if one assumes half that market size for winMo apps, we are talking possibly up to a decade or so to recoup the licencing costs. Thats just not feasible. More to the point, Its not at all GPL compatible , meaning its simply not possible to use without using the dual licencing option in PJSIP. The major problem with the G729 solution that Samuel has provided the community is that the Assembly optimizations are don't work in Visual studio, because , for some bizarre reason, compiler won't accept inline assembly for the ARM platform. It might be possible to use non optimized C routines, but from our experience the little arm chips in the windows phones, even the more gutsier offerings like the HTC ones, just don't seem to have the heavy lifting power to pull it off. Theres a possible work around using ARM intrinsics , but we haven't had a lot of luck with these yet. I haven't personally looked at it, but it might be a simple solution. Theres also some "DSP" versions of G729 that look like they are also based off the reference versions, that might be useable. Will find out later. Warm regards, Shayne.

Will find out later. Phones with TI OMAP 34xx or 35xx would be able to handle any voice codec thrown at them; they have an ARM core + a C64x DSP core. I think TI tools (CCS, or Code Composer Studio) support Linux (Android), Symbian, and Win Mobile (except for the Lin version I don't think CCS tools are free). But the bigger problem may be that TI has not worked their way into many phones... Palm Pre and Mot Droid but where else. -Jeff > On 06/03/2010, at 4:59 PM, Angel Of Retributioin wrote: >> Didn't try with the Samuel's instruction, but I've done with voiceAge Library.
