Thanks for the response. No worries, was just curious and figured it may be a lot of work. I rarely see VP9 used honestly.

Yeah, it's typically used for streaming by some providers. AV1 is also something to consider supporting. Who knows, one day I may get a burst of energy...or a contract.

Would it be possible to index a Dolby Vision FEL substream at the same time as its HEVC parent stream? So we can have 2 DGI index files that link back to the same source m2ts file(s), for easier use with something like DoviBaker

Currently I'm demuxing the Enhancement layer for each disc, per DoviBaker's instructions, and then indexing/referencing that. But it's just eating up extra disk space, when all the data it needs is already in the m2ts. Some of these tracks get up to 8-10GB!

Hello PoeBear. Nice to hear from you again.

Open the disk. Index the BL as usual. Then go into Stream/Set PIDs and change the Video PID to that of the EL stream. Now index again, using a different name for the DGI.

That will give you two DGIs referencing the original M2TS(s), one for the BL and one for the EL. That saves the disk space as you requested. Sorry but I cannot do the two indexing operations simultaneously.

Cheers! This worked, and outputs exactly the same in my frameserver

Would it be possible to have the Dolby Vision RPU demuxed as part of the indexing/demuxing process, or is how its embedded into the EL necessitate demuxing first?

Please use DDVT or dovi_tool for that. I don't have the knowledge or energy to try to implement that.

For streams with multiple videos, it is currently not possible to demux any but the first video from the stream. Would it be possible to allow for demuxing also the others?

It's a similar question to that discussed above with the DolbyVision BL and EL.

Go into Stream/Set PIDs and change the Video PID to that of the desired stream. You can't do multiple streams simultaneously, however.

Is it possible to boost DGSharpen() a bit more in 246? I like the new one but it's definitely more subtle at 1.0 than the old version & seems like the threshold for light maybe lower...or higher, i always forget which way thresh works...it seems not as intense rn.

Thank you for your feedback, Whackbag. I will look into it. Possibly we can offer different kernels controlled by an option.

Something good coming your way, Whackbag. Thank you for your patience.

Here is a test version for DGDecNV including an improved sharpener DGSharpen(). It also includes the DTS identification fix for DGIndexNV. The new sharpener has a more useful strength function to get stronger sharpening, overshoot/undershoot parameters to allow exceeding the local limit, and edge mask options to exclude ranges from sharpening (e.g., to avoid artifacts at the edges of letterboxing). Please refer to the included manual for details on the new parameters.

Your feedback will be appreciated. I will release this as build 247 after it is verified OK.

Cheers Rocky, i'll play around with it for a couple days and see how she fairs...thanx again.

Post by **Rocky** » Tue Mar 21, 2023 11:59 am

Thank you, Whackbag. BTW, if you set strength = 5 and everything else 0 it should be the same as the original (not the last iteration) with strength 1.0. Now you can go sharper if you wish, and you can violate the limiting in a controlled fashion.

245 (strength=1.0)

246test (strength=13.0, os=7)

I like the over sharpened look & i use a cube file not as intended, i don't use it for color correction but as a slight denoiser. So this is not a true apples=apples comparison as i figured if i was going to rerun a bunch of tests i may as well tweak some other stuff while i was at it (slight color change is from a chroma-qp-offset i changed in Staxrip).

So yeah...i'll keep playing with it for a bit...but i think this works for me.

Super. Thank you for your testing.
