Linux: Do we have support of HDMI on "Linux+ Bios" with TDA2XX SOC?.

Other Parts Discussed in Thread: TDA2

Tool/software: Linux

Hi There,

I am using "VSDK_03_01_00_00" version of "VSDK" with TDA2XX SOC and able to build "VSDK" successfully for "Linux + Bios" platform . After that I have tried to execute below mentioned use case.

"NullSrc + Decode + Display". For executing this use case I have followed below mentioned steps.

1. I did some configuration for Display and Capture by using "Setting" option(S) (Here I have selected "HDMI 1080P60 for Capture" and "HDMI 1080P60 for Display").

2. Ran the "NullSrc + Decode + Display" use case and used the "H.264 " codec.

3. During the execution of use case I got "ASSERT (nullSrcLink_tsk.c|NullSrcLink_fillData|202)" on the console.

I read somewhere that "Linux+ Bios" doesn't have HDMI" support and I am not sure is this the case with Linux build.

Could someone please give clarification on this?.

Regards,

Anshul Jain.

Hi Anshul,

the Linux version of VisionSDK supports HDMI (also in ver 3.01 was added support for LCD).
Your problem looks more like issue with reading the input file.

I have pinged VisonSDK experts to help.

Yordan

Yes, Yordan is correct.
VSDK_03_01_00_00 support HDMI display for both "Bios only" and "Linux + Bios" builds.
HDMI capture is not supported in VSDK Linux+Bios, and this feature is available only with Bios only version

Hi Shiju,

Thank you for your response.

As you have confirmed that HDMI capture is not supported in VSDK Linux+Bios. So in the same environment, can we have a input from "AVB" port and see the output on HDMI display.

Yes, AVB capture and HDMI display is supported on VSDK Linux+Bios.
please refer Linux user guide to build binaries and set-up for AVB

Hi
No HDMI capture is not supported with vision SDK Linux (Linux+Bios) on any TDAxx.
HDMI caprure is supported on TDA3x and TDA2x with VSDK Bios only cnfig. This is available with VSDK_03_01_00_00.
for TDA2+, HDMI capture will be supported in next VSDK release version VSDK_03_02_00_00
