Hi all,
I want to capture video data from FPGA using VIN0 ports, performing image compressor and then send back compressing video data to FPGA using VOUTo port. is it possible?
DM8186 FPGA
VOUT0[0..29] -----------------> VOUT0[0..29]
VIN0[0..23] <-------------------- VIN0[0..23]
Thanks,
Bonzai
Hi,
It is possible, you can treat your compressed data as if it is RGB888 data and capture it, it will be stored as RGB888, is that ok?

Hi, Brijesh.
I don't change anything, but it's OK now. I don't know why.
I want to write the capture data into file. So I use ipcFramesOutVpssToHostPrm and ipcFramesInHostPrm.
But it can not receive any data. what's wrong?
[m3vpss ] *** CAPTURE Statistics *** [m3vpss ] 42661: CAPTURE: Queued to driver = 12, Dequeued from driver = 12 [m3vpss ] CAPTURE [0] Buf Q Status [m3vpss ] Empty Q -> count 0, wrPtr 0, rdPtr 0 [m3vpss ] Full Q -> count 12, wrPtr 12, rdPtr 0 [m3vpss ] [m3vpss ] *** [NSF0] NSF Statistics *** [m3vpss ] 42661: NSF: Rcvd from prev = 0, Returned to prev = 0 [m3vpss ] NSF Out [0] Buf Q Status [m3vpss ] Empty Q -> count 0, wrPtr 0, rdPtr 0 [m3vpss ] Full Q -> count 0, wrPtr 0, rdPtr 0
Did you check your capture statistics and if it is all correct?

The logs indicate the link after capture link is not getting notification.Pls share .c file of your latest usecase. Do you have an application thread on A8 that does
Vcap_getFullVideoFrames & Vcap_putEmptyVideoFrames
Hi, I test capture-display, the capture Link is OK.

The thread is VcapVenc_ipcFramesCreate(usecase) which will get rid of display.
You have to add Vcap_start.ALso you have to modify /dvr_rdk/demos/mcfw_api_demos/mcfw_demo/demo_vcap_venc_vdis_ipc_frames_exch.c
Comment out call to Vdis_putFullVideoFrames & Vdis_getEmptyVideoFrames..Also make sure you are invoking VcapVenc_ipcFramesCreate
What is the problem you are facing
Hi, it stops in [m3video] Channel:0 inputframerate:30 targetfps:30. And it seems not receive data. Can you help me.

In the file you shared the issue is in file mcfw_cap_enc.txt
capturePrm.outQueParams[0].nextLink = gMultiCh_VcapVencVdisObj.ipcOutVpssId is wrong. CHange it to
capturePrm.outQueParams[0].nextLink = gVcapModuleContext.nsfId
Also make sure you modify VcapVenc_ipcFramesSendRecvFxn to comment out Vdis_putFullVideoFrames & Vdis_getEmptyVideoFrames
Hi, Badri.
I have changed the nextLink to nsfId[0].
I don't need to send data to A8, so I don't use VcapVenc_ipcFramesCreate(useCase);
I need to write 264 file, so I only use the thread VcapVenc_bitsWriteCreate();
the result is same.
