Encoder set params to mul slices output error

Hi hjintian,

Both Encoder and decoder can support IVIDEO_SLICEMODE and IVIDEO_FIXEDLENGTH for low-latency data communication.

But in EZSDK , OMX components/Frameworks are not implemented for this feature yet. 

It will work with only IVIDEO_ENTIREFRAME.

Hi Ram,

  Thank you for your reply.

  About OMX components/Frameworks,how do i implement for IVIDEO_SLICEMODE  feature?Can you tell me ?Any some example?

 When do you implement the IVIDEO_SLICEMODE feature on OMX components/Frameworks of EZSDK?

Thank you very much.

Regards,

Hi Ram,

  You say that OMX components/Frameworks are not implemented for this feature yet in ezsdk.And Can you tell me how to implement the slices feature in ezsdk?

  Thank you very much.

Hi Tory,

If you have installed ezsdk overlay package with ezsdk 05.05.02.00, you will have Encoder package in component-sources directory.

ivahd_h264enc_02_00_0x_0x_production\packages\ti\sdo\codecs\h264enc\app\Test\Src\h264enc_ti_config.c has sample callback functions getBufferFxn and putDataFxn.

You need to set getBufferFxn and putDataFxn call back functions to send the partial output buffer to encoder and to get the slice data from encoder along with setting outputDataMode to IVIDEO_SLICEMODE.

Refer Appendix G of H264 Encoder userGuide for low-latency data communication.

Hi Ram,

  Thank you for your reply.

  Where is ezsdk overlay package ?Can you tell me its url?Let me download it.

  Thank you very much.

Tory

Hi Tory,

You need to contact your local FAE to get EZSDK overlay package.

Thanks

Ram

Hi Ram,

  Thank you for your reply.

  My local FAE sayes that they donot have EZSDK overlay package.so you can give me EZSDK overlay package.My email is hjintian23@126.com.I hope you can help me.

 Thank you very much.

Hi ,

(1)  if i install ezsdk overlay package,does omx encoder support slices mode encodeing?

(2) Does RDK support slices mode encodeing?

(3) Is RDK compatible with our customed dm8168?

Hi ,

Overlay package can't be sent via mail. You need to get this from FAE.

Slice output from OMX encoder is possible but not in low-latency mode. i,e encoder encodes full frame as a group of slices. If this is what you want this can be supported with proper setting of OMX encoder.

But if you are looking for encoder to notify after encoding slice through a call-back, this is not implemented in any software stack(ezsdk, RDK).

Hi

  Thank you for your reply. 

  You say that slice output from OMX encoder is possible.Is it mul slices output?And can you tell me how to set omx encoder parameters for mul slices output?

 Thank you very much.
