TDA4VM: Can LDC convert YUV420P image into NV12 (YUV420SP) image?

Hi,

Is there any module that can meet the demand and convert YUV420P to NV12?

Hi Nancy Wang,

But how do you get YUV420 planar data? Is it semi-planar data?

I really dont thing any module in the TDA4 supports this format.

Hi,

Customer obtain H264 data through the network, and get YUV420P after decoding. Since the algorithm requires YUV420SP, in order to ensure real-time performance, it is necessary to know whether there is a module that can support conversion.

ok, if possible, can you please get YUV420SP from the H264 decoding stage? If this is possible, then we can use other modules in the TDA4 SoC.

Customer can get the decoded YUV420P image.

YUV420P (YUV420 complete planar) cannot be processed or converted in any of the module. I would suggest to get YUV420SP (YUV420 Semi Planar) from the decoder. YUV420SP is supported by most of the modules..

Hi,

What the customer needs is the data of YUV420SP. If there is no module that can convert YUV420P to YUV420SP, it can only be transferred with ffmpeg.

But which module decodes incoming h.264 stream? Is the TI decoder? Because if it is, then this decoder supports YUV420SP output format. 

Yes, there is no HW module to convert from YUV420P to YUV420SP format. You would probably have to use DMA, but i think it would be inefficient.
