Yuvraj, TVP5146 is not mandatory for DVTB to run. DVTB can run in Filebased mode where the input to the Encoder is YUV file. It's only that you need to get DVTB built right first which is fairly straightforward. I just wanted to see if the same usecase works in another application (DVTB with working script) which is in parallel to yours.
We tried the same usecase using DVTB in our DVSDK 2.0 development environment with the same parameters and the encoded output is proper. Can you check if you are setting the framePitch of the inBufDesc properly?

You would need to build the application (simple steps mentioned in the Release notes) for DM6446 platform, copy it to your target environment and run it with the default videnc1.dvs script provided in the DVTB package under dvtb_x_xx_xx\packages\ti\sdo\dvtb\scripts\dm6446.

Guess there are no failures observed. Can you send the absolute values for all the params that you use instead of variables?
