Facing issue in Interlaced encoding with EzSDK on DM814x based board

Other Parts Discussed in Thread: TVP7002

Hello TI,

We have DM814x based custom product. We are using EzSDK version 5.05.01.04 (ezsdk_dm814x-evm_5_05_01_04) in this product. I want to do interlaced encoding using capture_encode demo. I refer FAQ 3 in the link http://processors.wiki.ti.com/index.php/OMX_VENC and did relevant changes in my capture_encode demo.

When i played back the encoded file with Elecard it shows that encoded file is interlaced (interlaced : yes) but it has lots of noise on transparent video in background. I suspect that something is wrong with stride (or pitch), width or height because the elecard shows resolution as 720x1152 and one more observation is it plays with the maximum bit-rate something around 60-63 Mbps with PAL resolution even though declared bit-rate is just 4Mbps.

Please help as soon as possible.

Regards,

Hitesh

Hi Brijesh,

I could reproduce the jumping issue for 1080i capture with your iLClient and with the patch applied.

I will whow these generated h264 with Drviers team once.

Hi Ram,

Any hearing from the driver team?

We have tried much by changing various capture formats but still the captured YUV frame is having the jumps. I feel that this may be because of HDVPSS may be dropping some of the scan-lines of the input video but I am surprised that why this is not happening in progressive input.

Please take a follow-up with driver team and respond us as early as possible.

Regards,

Hitesh
