Hello,

I am trying to create a video encoder program by using the DMAI functions. I already created a working AAC decoder program, so I am familiar with the API quite a bit. The current code of the encoder fails during this call:

hEnc = Venc1_create(hEngine, "h264enc", &params, &dynParams);

Engine_open() works and hEngine is not NULL. The parameter structures have PAL D1 as maximum video resolution. param.size is set to sizeof(VIDENC1_Params). So I ran the program with CE_DEBUG=2. The output says, that XDM_SETPARAMS failed with status code -1, which boils down to the extremely helpful "unspecified error". Obviously, the failure occurs at the VIDENC_control() function, which is called by Venc1_create().

Does somone know, where the problem might be? Appended below is the debug information.

Best regards,
Andreas
