@harrymaurya05 Could you please take a look at #322? This sample is much more complicated than others, and the additions made in that PR would make HLS much more approachable.

[harrymaurya05]

sure thanks

I think #322 implements most hls options you're using, apart from master_pl_name.
If we'd add that option, we could update this PR to use the new output type and use it as an example.
