DM365_DVSDK-3_Failed to open decoder 'mpeg4dec'

Ashwani
Expert 1365 points


Hi Yaswant/Darren,

I am using DM365 dvsdk_3_00_01_10 on android platform. I am able to run gstreamer pipelines successfully and also able to see DMAI & CODEC Engine Debug messages by enabling CE_DEBUG=2 & DMAI_DEBUG=2.

#export DMAI_DEBUG=2
#export CE_DEBUG=2
#gst-launch-0.10 videotestsrc num-buffers=1 ! video/x-raw-yuv, format=\(fourcc\)NV12 ! TIVidenc1 codecName=mpeg4enc engineName=codecServer ! filesink location=output_gen_D1.mp4

I have integrated OMX-IL layer to access the h/w codecs thru opencore PV-Player. It is able to interact with DMAI & CODEC Engine layers.But I am not able to see any DMAI & CODEC Engine debug messages after enabling CE_DEBUG=2 & DMAI_DEBUG=2.

I have entered android DEBUG(LOGE/LOGI) messages in DMAI & CODEC Engine layers to debug the codec access.
getting following error messages.

    Hi All,

    I am able to get debug messages in case of OMX-IL. Below is the CE Debug messages:

    Why CMEM has not been initialized??

    I am able to run same .mp4 file with gstreamer pipelines without any error messages.
