Summary0000362: 12 bit lossless compression mode in JM
DescriptionHi Experts,

I am stuck in making 12 bit lossless compression mode to work in JM encoder.
Wanted to confirm if JM encoder supports lossless compression in 12 bit mode for YUV.

For lossless mode I have done the following.

1) set all quantization parameters (i/p/b-frames) to 0
2) set the lossless flag to 1 (qpprime_y is zero)
3) set the profile to 244.

Please point me in the correct direction if I am missing anything.

Thank you.

Best Regards,
Sujith
