AM335x - ICS: is video playback possible without SGX support?

Team,

Is the SGX support required in order to support video decode? Can SGX support be removed and can video decode still be supported or are there some dependencies?

Thanks and best regards,

Anthony

    Hi Anthony,

       SGX doesn't perform any video decode operations, decoding is done by S/W OMX codecs on Android ICS/JB.

    However you might need SGX for better performance as YUV/RGB conversion can be accelerated using SGX.

    Thanks Aditya.

    If you decide not to use SGX I guess that some changes are required to handle YUV/RGB conversion by SW. Are those changes needed at the Application level (Media player API) or in lower layer like stagefright framework?

    Or is this taken into account directly at compile time (since SGX support is removed some other SW package will replace it)?

    Thanks.

    Hello Anthony,

        I think Android s/w fallback mechanism should take care of the color conversion automatically if SGX drivers are not installed.

    But the output display may be slow (depends on video resolution).
