DM6467 EVM Decode Video & Audio

James 49929

HI,

I'm tryign to the the demo decode program to work with the supplied audio and video files but I'm having some troubles.

The board is booting via the evm harddrive, running uImage-dm6467t-evm.bin & uboot-dm6467t-evm.bin.

The evireoment is set as:

setenv bootargs 'mem=76M console=ttyS0,115200n8 root=/dev/hda1 vpif_display.ch2_numbuffers=0 vpif_display.ch3_numbuffers=0'

I am able to loadmodules fine.

When I try and run the decode program as below:

./decode -a /opt/dvsdk/dm6467/data/sounds/davincieffect.aac

Decode demo started.

    James,

     

    For Video, can you check whether /dev/video2 entry is available or not? If it is not available, check your bootlog to see what is failed while creating display driver.

     

    Thx,

    Few more points:

    The clip you are trying to play is 1920x1080 resolution clip. The decode arguments provided are for composite and PAL.

    I would try with following options to playout this clip in component interface

    ./decode -v ../dvsdk_data/dm6467/data/videos/dust_1080i_30fps.264  -y 5   -O component

    The board you are using, is it a DM6467T board?

    Regards

    Hi,

    The board is the DM6467, I've tried this command also have the same error.

    I have also tried to attack it using the gstreamer approach,  with DVSDK 3 thou I am having the following problem:

    Package glib-2.0 was not found in the pkg-config search path.

    Is this a simple error? Looking on the web seems to suggest libglib2.0-dev isnt installed thou I have checked this.

    Thanks

    As it is specified in the download page (http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/dvsdk/DVSDK_3_10/latest/index_FDS.html), DVSDK 3.10 supports DM355/DM365/DM6467T platforms only.

    You can try it out with DM6467 platform. In the GSG we have provided link to get uImage/u-boot for DM6467 platform (http://processors.wiki.ti.com/index.php?title=DM6467_Getting_Started_Guide#Software_Setup).

    To build DVSDK components for DM6467 platform, please make the change specified in http://processors.wiki.ti.com/index.php/GSG:_DVEVM_Software_Setup_for_DM6467_Platforms#Building_the_DVSDK_Software_for_the_Target.
