Other Parts Discussed in Thread: TVP5158

Hi all

I have a mistral version DM8148 evm board and a customized board with 2 tvp5158 on it.

I have successfully ported the DVRRDK_02.00.00.23 and can run DM814x demo.

I have test the capture,h264 encode,h264 decode,hdmi display and standard display.

all works well excep one thing.

I see a lot of record file with name VBITS_DATA_x.bin and VBITS_DATA_x.bin.mv but where

is the jpeg(mjpeg file)?

My usecase is VSYS_USECASE_MULTICHN_PROGRESSIVE_VCAP_VDIS_VENC_VDEC_8CH.

so I think the mjpeg file maybe VBITS_DATA_16(or above).bin , but the file size is 0.

Wang,

For MJPEG also file extension is h264. Just look for the file with appropriate channel no. E.g file VBITS_DATA_32.h264 is of channel no. 32 and is of mjpeg format but extension is h264.

Do you want to enable write of MJPEG stream to file ?

If so modify /dvr_rdk/demos/mcfw_api_demos/mcfw_demo/demo_vcap_venc_vdec_vdis_bits_rdwr.h

#if defined(TI_814X_BUILD) || defined(TI_8107_BUILD)
#define MCFW_IPC_BITS_FWRITE_ENABLE_BITMASK_DEFAULT (MCFW_IPC_BITS_FWRITE_ENABLE_BITMASK_CHANNEL_0_CHANNEL4_CHANNEL_8)
#else
#define MCFW_IPC_BITS_FWRITE_ENABLE_BITMASK_DEFAULT (MCFW_IPC_BITS_FWRITE_ENABLE_BITMASK_CHANNEL_0_CHANNEL16)

#if defined(TI_814X_BUILD) || defined(TI_8107_BUILD)
#define MCFW_IPC_BITS_FWRITE_ENABLE_BITMASK_DEFAULT (MCFW_IPC_BITS_FWRITE_ENABLE_BITMASK_ALLCHANNELS)
#else
#define MCFW_IPC_BITS_FWRITE_ENABLE_BITMASK_DEFAULT (MCFW_IPC_BITS_FWRITE_ENABLE_BITMASK_CHANNEL_0_CHANNEL16)

The encoder channel numbers are as follows:

0 -> (NumPrimaryChannels - 1) :: H264 Primary resolution

NumPrimaryChannels -> (NumPrimaryChannels + NumSecondaryChannels) - 1 :: H264 Secondary resolution

(NumPrimaryChannels + NumSecondaryChannels) -> (NumPrimaryChannels + NumSecondaryChannels + NumPrimaryChannels) :: MJPEG streams
