To save more than 1 channel you will have to modify:

/dvr_rdk/demos/mcfw_api_demos/mcfw_demo/demo_vcap_venc_vdis_bits_wr.c

void *VcapVenc_bitsWriteMain(void *pPrm)

if(pBuf->chnId== gVcapVenc_ctrl.fileWriteChn && fileWriteState == FILE_WRITE_RUNNING)

Change above line to save multiple channels that you require

How to modify "if (pBuf - > chnId = = gVcapVenc_ctrl. FileWriteChn && fileWriteState == FILE_WRITE_RUNNING) "line to save two channel video file?

The function VcapVenc_bitsWriteMain is very simple .You can go thru it to understand.

1. You have to open one file handle per channel you want to save.,

2. If channel id matches the channel you want to save , write into the corresponding file handle.
