enc dynamic parameters set

hi all.when i set all the enc dynamic parameters at the same time over some range,it will be segment fault.

for example

RcAlg=0(VBR)

Resolution=(1920*1080)

encIntraFrameInterval = 500;

FrameRate = 60

BitRate = 40000

qpMin = 20;

qpMax = 52

BUT I JUST change the Resolution to 352*288 ,it will not have segment fault .

alse i change the BitRate = 50000,encIntraFrameInterval =200,it will alse have segment fault.

if i just change one parameters at run time,i will have the following errors,but app is still running and not down

Enter Choice: [m3video] 60530:!ERROR!:ENCLINK::links_m3video/iva_enc/encLink_h264.c:[232]::INTERNAL ERROR:-1
[m3video] ALGCONTROL FAILED:CMD:1
[m3video] ERROR: IH264ENC_LEVEL_INCOMPLAINT_PARAMETER , 0,
[m3video] 60531:WARN
[m3video] ENCLINK: ERROR in Run time parameters changes, Extended Error code:1

so how should i constuct the above parameters.

What is the dvr rdk release version you are using?

dvr rdk 4.0

Could you explain the stream parameters?

Are you trying to encode 1920x1080 with a bitrate of 400 Kbps & I frame interval of 500 (one I frame for every 500 frames)?

Please get a dump of static & dynamic parameters.

Also, encoder lib in 4.1 codebase has additional extended error codes to identify exact error. It will be help if you could migrate to this version.

yes . the RDK demo is to set the enc parameters dynamiclly for just one parameter ,for example ,just framerate or resultion and so.i test that set all above parameters at the same time.

and if they were over some range ,it will be segment fault .i want to know the right range,so i can set the parameters rightly at the same time.

tks

This particular error is an issue with your qP settings; other parameters should be ok.
