OpenVisualCloud / SVT-HEVC

SVT HEVC encoder. Scalable Video Technology (SVT) is a software-based video coding technology that is highly optimized for Intel® Xeon® processors. Using the open source SVT-HEVC encoder, it is possible to spread video encoding processing across multiple Intel® Xeon® processors to achieve a real advantage of processing efficiency.

How to add MCTS SEI ? #556

Closed leokinglong closed 3 years ago

leokinglong commented 4 years ago

hi~ @tianjunwork How to add mcts SEI info to hevc file ？ For example，Motion-constrained tile sets extraction information sets SEI message，thanks~ image

Hi @LeoKingLong , currently we don't support inserting motion-constrained tile sets extraction information sets SEI message yet.

Hi @yanyings , do you use this SEI with SVT-HEVC in 360SCVP?

Hi all,

We don’t add the motion-constrained tile sets extraction information sets SEI currently in 360SCVP. But we have added the RWPK, projection frame packing and viewport SEI in 360SCVP, maybe give you a reference. https://github.com/OpenVisualCloud/Immersive-Video-Sample/tree/master/src/360SCVP

Thanks, Yanying

Thank you @yanyings providing the insight.

Hi @LeoKingLong , if your use case is 360 video streaming, 360SCVP library is a good example of utility that handles the hevc bitstream. https://github.com/OpenVisualCloud/Immersive-Video-Sample/blob/master/src/doc/Immersive_Video_Delivery_360SCVP.md

SEI can be generated and written to elementary stream beyond the encoder. 360SCVP shows example how you can do it. E.g. Omnidirectional viewport SEI message

I360SCVP_SetParameter(, ID_SCVP_PARAM_SEI_VIEWPORT, )
setViewportSEI
hevc_write_ViewportSEI
