DM8127 RDK 2.8- How to get the FramesBuf for YVU not raw data
I use DM8127 RDK 2.8 and demo code steting is vsysParams.systemUseCase = VSYS_USECASE_MULTICHN_TRISTREAM_FULLFTR
and I want to get 1080P YUV data for my own app use.
But the demo code only App_ipcBitsInit();
I try this fun: Int32 Vcap_getFullVideoFrames(VIDEO_FRAMEBUF_LIST_S *pFrameBufList, UInt32 timeout) in Ti_vcap.c
but I get FrameBuf once only so who can tell me how to get.

Dear time derek,
1. I use IPNC_RDK 3.2
2. I modify the Rules.make
# Capture Display Use case
CAPTURE_DISPLAY_MODE_ON := YES
# Set this flag to "YUV" = YUV frames (secondary stream only) will do a round trip M3-A8-M3 to reach the SD display # Set this flag to "RAW" = RAW frames will be sent to A8 and then back to M3
FRAMES_TO_A8 := YUV
3. Then you can get the YUV FrameBuf
4.This is all I got so far.
have a nice day.
dear VK ...
Thank you for your answer , but I used the RDK 2.8 , It doesn't have ti_mcfw_ipcframes.c ,but has ti_mcfw_ipcBits.c .
Does it can be used in ti_mcdw_main.c to get YUV Data ?
And could you tell me which fun() do you choosed ?
thanks again .
Dear Time Derek,
The ti_mcfw_ipcBits.c is getting the Image after ENCODE.
I used the IPNC_RDK 3.2, so it has the fun what I told you.
I don't made the IP cam product or something relation. I afraid I can not help you. But you can refer ITT folder in demo.
It is use DCC software on PC via TCP/IP to get the YUV framer buffer,
You just move to IPNC_RDK 3.2, it might be a quickly way.
I tried the rdk 2.8 to use funs in ti_vcam.c or ti_vcap.c.
I want to get the yuv framebuf in main.c but it does not work, you can take a look what I posted and I don't get it.
dear VK ...
My goal is in full mode, main code flow to provide network transmission, second code spread to DSP algorithm to DSP after 264 decoding.
But now I can't find the two code flow place. Also don't know this from which laid a hand on him, what about your can give some ideas?
