DVRRDK2.8 decode and display B frame

Thank you!I solved the problem!But the decoded Interlaced H264 video has Green block,I have seen a topic to discuss the problem.

Is the stream you have shared in this post a interlaced h264 stream ? If not pls share the stream.

yes, thanks! In fact I don't know whether is interlaced H264 stream leads to the problem. but this stream really do exist the problem!

I will try out your stream on Monday on latest RDK release on Monday and update you.

I have tried the stream you shared on DVR RDK 3.5 release. It plays fine and I was not able to see any artifacts .The following changes were required to get the stream functional:

The stream you shared has issues

It does not start with SPS/PP. Cut the stream such that it starts with SPS/PPS.

Changes in ini file:

displaydelay= 4 (Stream has 4 reference frames)

numbuf = 10 (As 4 buffers are locked , need more output buffers)

width     = 1920

height    = 1080

Changes in multich_vdec_vdis.c

mulich_vdec_vdis_set_avsync_vidque_prm()

Change

        queCfg->avsyncEnable = TRUE;

to

        queCfg->avsyncEnable = FALSE;

This change is required due to a demo issue where timestamps are not set correctly for the elementary stream. This will not be an issue with real application which sets correct timestamp.

Changes in multich_vdec_vdis.c

MultiCh_createVdecVdis()

Change:

 decPrm.chCreateParams[i].processCallLevel   = VDEC_FRAMELEVELPROCESSCALL;

to

 decPrm.chCreateParams[i].processCallLevel   = VDEC_FIELDLEVELPROCESSCALL;

This is to enable decoding of interlaced content

Thank you very much,Badri Narayanan, you gave me a lot of help!
