a problem about dm8127 A8 getting the 5M YUV

John Lin57981

I meet a new problem. When I send the two channel YUV frames to A8 with  the resolutions 1080I and D1, the two h264 streams work fine. However, when I change the resolution to 5Mega(2432X2048) and D1, the 5M h264 streams  couldn't work fine. When I connet the 5M h264 stream, VLC play the video stream ok for seconds, then the stream stops. It's very strange. But  the D1 h264 stream still work fine.  From the uart log information,  the two streams stills work and A8 get the two streams continuous.

Everything seems ok except PC can't continuously get the 5M H264 stream under the following usecase.  Besides, i have check that 5M and D1 streams work ok under low power usecase.

 

camera link--->Merger LInk-->IpcFramesOutLinkRTOS-->IpcFramesInLinkHLOS--> IpcFramesOutLinkHLOS-->IpcFramesInLinkRTOS-->ipcInVideo

 

So can I send the 5Mega YUV to A8 ?  or something that I have to modify?  

Please help me, thanks!

 

BTW, dm8127, appro rdk 3.2, custom board!
