I would like to raise the problem related to DM365 JPEGENCODE issue .

my sdk is dvsdk_2_10_01_18

I do my test as fllows:

First , I modify the "encode" demo to capture a yuv file .The demo locates in \dvsdk_demos_2_10_00_17\dm365\encode\

In capture.c file ,I add some code to save one yuv frame .

/* Capture a frame */

if (Capture_get(hCapture, &hCapBuf) < 0)

{

ERR("Failed to get capture buffer\n");

cleanup(THREAD_FAILURE);

}

fwrite(Buffer_getUserPtr(hCapBuf), Buffer_getNumBytesUsed(hCapBuf),1,outFile); //save one frame yuv file

.........

sure , I can get the yuv file and get the h264 file too ,the h264 file can be played by vlc player.it says: the encode demo works well .

Second, I use jpgenc-r demo to compress yuv file which I got .

This demo is at \dm365_codecs_01_00_06\packages\ti\sdo\codecs\jpegenc\

the demo should use some params as bellow:

# <ParameterName> = <ParameterValue> # Comment
