Not recovered from decode error .

Masamitsu Kijima

We are using "ti-dvsdk_dm365-evm_4_00_00_22" , and decode H264 .

( Decode stream made by DM365 . (high profile / Level 4 / 1280x720 / 4Mbps / 15fps ) )

Causing a packet loss, DecodeErr cause.( Vdec2_process() return Dmai_EBITERROR )

After eliminating packet loss, IDR is received.( Vdec2_process() return Dmai_EOK )

But , Decoded image still remains DecodeError . ever after ..

I was investigated, perhaps because IH264VDEC_Params.displayDelay = 1 .

If IH264VDEC_Params.displayDelay = 16 , such a phenomenon does not occur . 　( Recovered error )

Why would not IH264VDEC_Params.displayDelay = 1 , when DecodeError occurs ?

thank you .

Kijima-san,

Is it possible to capture the incoming stream to the decoder and send it across to us. We would like to run the stream here and find the issue.

I agree that with displayDelay = 1, the decoder should have still recovered from error.

regards

Yashwant

Dear Yashwant,

Thank you for your reply .

This issue was my mistake.　How to use the Decode Buffer was wrong.

Thank you .
