Linux codec support for H.264, MJPEG and WMA

Other Parts Discussed in Thread: AM3505

Hi

We are considering AM3505 for a streaming project and want to know if TI has a standard bundle for the subject software codecs.

    The AM3505 has no DSP or hardware acceleration for codecs like the other Davinci and OMAP based devices, so there are not currently any codecs specifically for the AM3505 from TI. However as the AM3505 has a powerful Cortex-A8 it is certainly possible to implement such codecs, I believe Ittiam has some Cortex-A8 based codecs that should work on the AM35xx series, and there are likely other third parties out there with solutions as well.

    A second option is to use some of the open source codecs, which are already heavily used on i.e. the BeagleBoard and Gumstix Overo boards...

    Good luck

    Thanks for suggesting Beagle board for study.

    The Beagle board CPU has both an Arm core and a DSP core, suppose the codec will make use of both to the best decoding effect. However, AM3505 does not have the DSP core and the codec must be running on the Arm Cortex-A8 only.   

    My suggestion to TI is to ready the standard codecs for Linux and refer the customer to algorithm vendors for a special tune only if it is necessary. Most SoC vendors do the same, just like the special codec bundle that is available to DM365 and DM355 users.

    Hi Ted,

    I basically agree with you. I however just want to make sure, that you know that you can get plenty of "standard" codec for Beagle (OMAP3/Cortex-A8 in general) only utilizing the Cortex-A8 core. Look i.e. at FFMPEG, which to my knowledge doesn't utilize the DSP for anything...

    Good luck with your project
