    Hi Widic,
    Yes, Support for Gstreamer video playback is available in Vision-sdk3.05. But for this IPU2 firmware needs to use ipumm firmware from PSDKLA. This information has been documented in the UserGuide.

    Only video playback with GST is tested. What is the encoding usecase you are looking for?
    As you know that VIP is controlled from M4 in vision-sdk , so you will not be able to you v4l2src plugin to capture from A15 and encode it.

    Hi, Ram,

    I want to use encode link on M4, on the other hand, I want to use GST playback on A15 for multimedia.

    could you give me some suggestion. thanks.

    Hi Widic,

    Both your usecases need different firmwares on ipu2.

    This seems not possible.

    Hi, Ram

    If I want to use this feature, whether can support the two feature at the different time.
    Is it possible?

    Can you provided more details for 0001-gstducati-Enable-encode-decode-for-vDRM-setup.patch and how to add ?

    Hi Widic,
    There is one option to use encode and decode from vision-sdk but both have to be from single links-chain.
    Currently using enc link + gst decode is not possible since both use different firmwares.

    With VIsion-SDK3.04 onwards vDRM was default drm driver but for ducati, omapdrm driver is required for buffer allocation in TILER. Hence this patch was created. If you have yocto , you can apply this patch and rebuild. The vision-sdk filesystem already has this libgstducti.so built and is available in the filesystem.
    but there is one memory leak issue with this patch and the fix will be available in Vision-SDK v3.06
