DM8127 H264 GDR codec

Antimax Antimax

Other Parts Discussed in Thread: DM385

Hi，
I have a problem with DM8127 H264 codec about GDR mode.I have enable the GDR mode with "intraRefreshRate = 2;gdrOverlapRowsBtwFrames = 1;".But the paramsters "IH264ENC_CTRL_START_GDR" must be set periodic. If you just set only once, it just refresh one frame, and will not continue. So it is right ?
And when I set IH264ENC_CTRL_START_GDR , the current frame will be very bigger. So how can I control it ? I have a sample H.264 stream by others. The rate control is must better . How they do that ?

Hi,
Can you tell me the below details?
1. Are you encoding interlaced or progressive?
2. What is the intraRefreshMethod you set?
3. encodingPreset = ?.
4. By seeing the snapshot attached, I assume you dont encode any B-frame. Please confirm this.

Also Refer to H.264 Encoder user guide's APPENDIX-O. This will give you an idea on how to use GDR.

Hi，

1. I am encoding progressive.

2. .intraRefreshMethod = IH264_INTRAREFRESH_GDR

3.encodingPreset = XDM_USER_DEFINED;

4.I do not encode any B-frame.

The GDR refresh need to be acvtived by "IH264ENC_CTRL_START_GDR" periodly , or not ? Now If I set IH264ENC_CTRL_START_GDR, the GDR will refresh .But when it refresh the whole frame, it will stop. And I need to set IH264ENC_CTRL_START_GDR to restart. Is it normally ?

Hi,

Thanks for the details.

yes. It needs to be set periodically. It is normal behaviour.

Hi,

Thanks.

But how to control stream rate like that ? I need the bitrate to be smooth . But when I set IH264ENC_CTRL_START_GDR, the current frame length will be more bigger than others. But why ?

Hi,

Can you share your encoder parameter settings?

Hi,

Can you set these and try.

rateControlPreset = User defined;

rcAlgo = VBR;

initialBufferLevel = HRDBufferSize = 2* TargetBitrate;

Can you increase the intraRefreshRate value and check? (When intraRefreshMethod == IH264_INTRAREFRESH_GDR, intraRefreshRate is treated/interpreted number of rows to be intra refreshed per frame.)

Also

What is the resolution you are encoding?

Hi,

I have done it as your say. But it is no effect. I found that the I mb size when I set IH264ENC_CTRL_START_GDR is more double size than others. I think it is may be the key . 8000.zip

Hi Antimax,

Can you share the other stream where you see the better compression? Also did you try modifying intraRefreshRate = 4 & gdrOverlapRowsBtwFrames = 2; I dont have a ready setup to test these.I will get back to you once I try this.

Mean while you can try modifiying gdrOverlapRowsBtwFrames & intraRefreshRate

Hi，

I am sorry. The video stream can not be made public. I have try as you say, but no effect . How can I send the stream to you in private ? Thanks you.

Hi Antimax,
Thanks for sharing it privately. Can you please tell, which encoder was used, where you see better compression?

0 Antimax Antimax over 6 years ago in reply to Prashanth Kumar15

Hi,
The better compression is encoded by DM385. But I do not know the detail things.

Hi Antimax,
Thanks for the details.
Can you try this and let me know your observation?

rateControlPreset = User defined;

rcAlgo = CBR;

initialBufferLevel = HRDBufferSize = (1/2* TargetBitrate);

You can also refer to the sample test app provided with IPNC-RDK @ ../Source/ti_tools/codecs-dm814x/REL.500.V.H264AVC.E.IVAHD.02.00.07.01/500.V.H264AVC.E.IVAHD.02.00/IVAHD_001/Client/test

What is the encoder version are you using?
