Linux/TDA2PXEVM: how to run a gstreamer pipeline with vision sdk?

Part Number: TDA2PXEVM

Tool/software: Linux

Hi,

Can you help demonstrate how to run a gstreamer pipeline with vision sdk? eg.  with capture/encode/decode/vpe/display components involved.

Is chains and links framework still a necessity for the running? Thanks!

Regards,

Simon

    Hi Simon,
    What is the vision-sdk version being used? If it is VISION_SDK v3.03 or lower version, gstreamer should work.
    Vision-SDK 3.04 doesn't have support for gstreamer .

    What is your exact usecase?

    Thanks

    Hi Ram,
    Thanks for your reply. we have plan to support DVR functionality in our ADAS portfolio based on TDA2x. Where can I start the gstreamer pipeline for VISION_SDK v3.03 or lower version? Can you help indicate some documents ? And what's the justification for you to abandon the support in later versions?

    Regards,
    Simon

    Hi Simon,
    If you are using VisionSDK Linux, the filesystem will have gstreamer support. Are you using VIsionSDK RTOS or Linux ?
    Gstreamer support in vision-sdk support will be available in VISION_SDK v3.05 which will happen in this month end. This support was broken in 3.04, due to a new feature vDRM.

    Hi Ram,
    I get it. We are using VISION_SDK Linux.  If possible I'd like to learn more about gstreamer plugins implementation based on Links and Chains framework, seems there are nothing about the topic in the VISION_SDK documents. Thanks!

    Regards,
    Simon

    Hi Simon,
    To run video playback gstreamer usecases, IPU2 needs to be loaded with IPUMM firmware. Refer UserGuide for more information on how to build vision-sdk firmwares for IPU2 with IPUMM as the firmware.
    If you are expecting a gstreamer plugin for capture , v4l2src can not be used since VIP is controlled by vision-sdk and not available for Linux
