[FAQ] SK-TDA4VM: Why Does Encoding Fail in TDA4VM-SK Edge-AI 9.1 SDK?

Why is my basic GStreamer encode pipeline failing as a result of "Failed to allocate required memory" in Edge-AI 9.1 SDK?

    This is to address the FAQ of the memory allocation failure that persists when running a GStreamer encoding pipeline in SDK 9.1.

    Encode Pipeline Testing:

    This can be seen running any encoding pipeline as shown below:

    GST_DEBUG=v4l2*:5 gst-launch-1.0 videotestsrc num-buffers=100 ! video/x-raw, format=NV12, width=1280, height=720 ! v4l2h264enc ! fakesink


    Reason:

    A patch was released as part of the 9.1 SDK in the release image to GStreamer in order to reduce latency in CSI. This had resulted in the failure to allocate memory issue you are seeing. Patches to fix this are being worked on but will likely be released as a part of the 9.2 SDK. Any further updates will be posted here.
