SWOSD in DVRRDK2.8

Strachey

Hi,
I used 8168EVM + DVRRDK2.8, and I had several problems as follow about SWOSD and SCD in the usecase of multich_progressive_vcap_venc_vdec_vdis of the demo.

Thanks !

    1、What's the different effects between used SWOSD and not used ?
    2、What's the different between processLink and nextLink ?
        ipcFramesOutVpssPrm[0].baseCreateParams.processLink = gVcapModuleContext.ipcFramesInDspId[0];
        ipcFramesOutVpssPrm[0].baseCreateParams.notifyProcessLink = TRUE;
        ipcFramesOutVpssPrm[0].baseCreateParams.noNotifyMode = FALSE;

        //prevLink->processLink->nextLink
        ipcFramesInDspPrm[0].baseCreateParams.inQueParams.prevLinkId = gVcapModuleContext.ipcFramesOutVpssId[0];
        ipcFramesInDspPrm[0].baseCreateParams.inQueParams.prevLinkQueId = 0;
        ipcFramesInDspPrm[0].baseCreateParams.numOutQue   = 1;
        ipcFramesInDspPrm[0].baseCreateParams.outQueParams[0].nextLink = gVcapModuleContext.dspAlgId[0];

What's the different effects between used SWOSD and not used ?

- If SWOSD is used it will apply a application provided logo on the encoder frames.If you are using RDK 2.8 you will also see the same logo on live display.

What's the different between processLink and nextLink ?

-- If the output buffer of link A is sent to link B , and when linkB returns the output buffer back to linkA if buffers are freed then it is nextLink.Below is how linkA and linkB are connected:

linkA ---> linkB

-- In process link, connection is as below

http://www.asciiflow.com/#228740264287163962/469586348

As you can see it is like a "T" connection.

Here link C is the process link

ProcessLink is used when the linkC does not have a output buffer but instead does the operation on the input buffer. For example SWOSD adds a grpx logo on the input video frame and returns the video frame.

The frame returned by processLink is then sent to the nextLink

The code as follow,the osd's chain :capture -> ipcFramesOutVpss -> ipcFramesInDsp -> dspAlg[0] -> SYSTEM_LINK_ID_INVALID ?dspAlg[0] has no output?

-- yes SWOSD is dspAlg[0] and does not have output buffer. It adds the logo on the input frame and returns the frame

Hi Badri,

Thanks for your reply !

what 's the relationship between SWOSD and grpx ?

When I seted "#define USE_FBDEV 0", the logo disappeared.

Thanks !

Best regards!

0 Badri Narayanan over 12 years ago in reply to Strachey

TI__Guru 59700 points

There is no relation. Where are you seeing the logo ? You should see the logo on the encoded frame not on the display.

0 Strachey over 12 years ago in reply to Badri Narayanan

Is that means the logo I saw in the four corners was producted by grpx, and the logo producted by SWOSD would be saw after decoding the encoder frames?

Thanks !

Best regards !

Yes that is correct

Hi Badri,

My chain is like that :

http://www.asciiflow.com/#Draw6293717893053921258/685765969

But I could not see the logo in the encode file .How could I try?

Best regards!

The chain looks correct .Can you share the source code where you connect the links. I want to check if links are setup correctly. Also pls share your app code where you setup the OSD window params. Also is your capture interlaced or progressive.You dont have DEI in your chain so if capture is interlaced it will cause encoding to be interlaced which is not supported in RDK.

Hi Badri,

Oh sorry, I shielded the function Demo_osdInit,and now I can see the logo in the encode frame.

Thanks !

Best regards!

Hi Badri,

By the way, is it all the algorithm in the DSP should use processlink, not use nextlink?

Thanks!

Best regards!

0 Badri Narayanan over 12 years ago in reply to Strachey

TI__Guru 59700 points

No not all alg in DSP should be processLink. Use processink only if you have "T" like connection as I mentioned previously. You can also use nextLink for DSP alg but it does not make sense for SWOSD.

Hi Qinzhan Chen,

I want to know where you can see the logo in the encode frame,Or where you can fnd the FrameBuffer.

Thanks!

Best Wishes!
