Hello!
I use imx-lib-11.09.01 (VPU firmware version: 1.4.41, VPU library version: 5.3.2) on Linux-2.6.35.3.
I try configure VPU on using H263:
encop.EncStdParam.h263Param.h263_annexIEnable = 0;
encop.EncStdParam.h263Param.h263_annexJEnable = 1;
encop.EncStdParam.h263Param.h263_annexKEnable = 1;
encop.EncStdParam.h263Param.h263_annexTEnable = 1;
Unfotrunally vpu_EncGetInitialInfo exit with -1 on this configuration.
I have to encode 1280x720@25 stream, because I configure codec on H.263v2 (H.263 - Wikipedia, the free encyclopedia) I think problem not in resolution and framerate.
How can I solve this problem, unfortunally technical support not help?
Thank you and excuse my bad english.
Solved! Go to Solution.
Problem solved, you should use follow H263 parameters: I = 0, J = 1, K = 0 and T = 0, quantParam should be not less than 1.

Hi,
I tried H.263 with JKT enabled (I=0, J=K=T=1)on my imx53 board, it works.(FW 1.4.41, vpu lib 5.3.2)
So I think there must be some other incorrect configuration lead to the init failure.
Can you double check whether it works for I=0, J=1, K=T=0 ?
Another way, you had better refer to our unit test codes to set the proper parameters.

Hello!
Unfortunally with I=0, J=1, K=T=0 I get -3 on vpu_EncStartOneFrame command.
