Hi, finally I have this working.
Cristiano, I have used your code to get information from the image. I have also
changed doSpecialFrameHandling because you don't have to send the DRI header
for images that don't have this markers.
u_int8_t RestartMarkerHeader[4]; // the special header
u_int16_t restartInterval = source->restartInterval();
if (restartInterval > 0 )
{
RestartMarkerHeader[0] = restartInterval >> 8;
RestartMarkerHeader[1] = restartInterval;
RestartMarkerHeader[2] = 0xFF;
RestartMarkerHeader[3] = 0xFF;
setSpecialHeaderBytes(RestartMarkerHeader, sizeof RestartMarkerHeader,
sizeof mainJPEGHeader /* start position */);
}
Ross, thanks for the new release. I have tried it and is not working here.
Maybe I'm doing something wrong, could you send one JPEG image working? If you
want I can send two test images with and without restart markers for you to
test.
Cheers.
