Greetings,
The dvsdk encode demo in DM365 doesn't support the jpeg encode algorithm. So I modified the code to make the jpeg encoder work based on the encode demo in dvsdk.
At first, add following to the encode.cfg:
var JPEGENC = xdc.useModule('ti.sdo.codecs.jpegenc.ce.JPEGENC');
var myEngine = Engine.create("encode", [
{name: "mpeg4enc", mod: MPEG4ENC, local: true, groupId: 1},
{name:
"h264enc", mod: H264ENC, local: true, groupId: 1},
{name: "jpegenc", mod: JPEGENC, local: true, groupId: 1},
{name: "g711enc", mod: G711ENC, local: true},]);
Sencond, invoke the jpeg coder in the programme:
/* Set up codec parameters */
IMGENC1_Params params;
params.maxWidth = envp->imageWidth;
params.maxHeight = envp->imageHeight;
params.size = sizeof(IMGENC1_Params);
params.maxScans = 1;
params.dataEndianness = XDM_BYTE;
if (colorSpace == ColorSpace_YUV420PSEMI) {
params.forceChromaFormat = XDM_YUV_420SP;
} else {
params.forceChromaFormat = XDM_YUV_422ILE;
}
dynParams.inputWidth = params.maxWidth;
dynParams.inputHeight = params.maxHeight;
/* Create the video encoder */
hIe1 = Ienc1_create(hEngine, algname, ¶ms, &dynParams);
if (hIe1 == NULL) {
ERR("Failed to create video encoder: %s\n", envp->videoEncoder);
cleanup(THREAD_FAILURE);
}
But video coder creation failed. After using CE_DEBUG=1, the console output is:
@2,417,953us: [+7 T:0x43782490] ti.sdo.ce.alg - ALG_create> algInit call failed

Finally, I found the corresponding code in the dmai code:
hEncode = IMGENC1_create(hEngine, codecName, params);
if (hEncode == NULL) {
Dmai_err0("Can't open imaging encode algorithm\n");
free(hIe);
return NULL;
}
if (hEncode == NULL) {
Dmai_err0("Can't open imaging encode algorithm\n");
free(hIe);
return NULL;
}
That mens the invoke of the IMGENC1_create() failed.
Any advice or hint will be grateful.
Best Regards;
