Hi all, I am using dm365, with gstreamer. I build a simple pipeline, which is:
v4l2src->capsfilter->dmaiaccel->dei->dmairesizer->capsfilter->dmai_jpeg->capsfilter->appsink.
Often, this pipeline crashes on startup with SIGSEGV.
I debug it today.
Here is what I find.(with CE_DEBUG=2)

So I am very confused. I looked the code in codec_engine_2_24 and framework_components_2_24_01, within my dvsdk_2_10_01_18, but I am not smart enough to find why the strncmp caused SIGSEGV.
Any help is appreciated.
