I cam currently looking into accelerating video playback on the OMAP2420, OMAP2430, OMAP3430 and eventually the OMAP3530 (once we recieve some hardware). >From what I understand, we can use the v4l2 interface to send buffers to the display hardware, which will do the scaling & YUV->RGB conversion in hardware. However, I was wondering what the options are for doing mpeg decode in hardware too. I believe the DaVinci platforms ship with GStreamer elements which will do MPEG decoding on the DSP and provide the output to a seperate GStreamer video sync. Are there any gstreamer elements avaliable to do the same on the OMAP2 & OMAP3 processors? If not, how can we accelerate the MPEG decode? We eventually want to be able to switch to rendering video frames into off-screen buffers. We hope this will allow us to upload them as a textures, which our compositing system can use for window animations. Once the animation has finished and windows are static, we'd then switch back to using the v4l2 overlay. Help & advice is greatly appreciated! :-) Cheers, Tom PS: This is a repost ater the original was sent to the old mailing list.
