[RESOLVED] Possibility to index 10-bit encodes

Post by DJATOM » Thu Apr 13, 2017 5:30 am

I know that DGDecIM does not support 10 bit decoding, but I use .dgi files for finding IDRs and "fixing" bad parts in already encoded files. DGDecNV can index 10-bit encodes, but recently my GTX 750's Fan died (I bought new one on Alliexpress and waiting for delivery), so now I'm on iGPU and can't index with NV for one month or so.
It would be nice if you make DGDecIM capable of making indexes for 10-bit files or make separate tool (if you don't want to allow indexing there).

Sorry to hear about your fan problem. It can be exasperating when the HW does not play nice.

Are you talking about 10-bit HEVC? Adding HEVC support to DGDecIM is way down on my priority list. It certainly won't get done before your replacement fan arrives, if ever.

Nope, I meant *.264 files. I don't need "valid" playback, just allowing to index is fine. DGDecNV can index 10-bit .264 files (the decoding is broken though). When trying to index with DGDecIM I'm get

Error

10-bit encodings not supported!

ОК

Ah, I see. Let me take a look and see if I can fix that easily.

I slipstreamed b50 to remove that test for DGIndexIM.

I am curious about your use case for making indices without decoding. What do you do with the index files?

As I said earlier, I need that to know where IDR frames placed, than I can replace that GOP from fresh encode (my use case is fine-tuned filtering on fades, banding removal, custom anti-aliasing and other scene-like optimisations). So I take into account where IDRs placed and pad it with few frames at start and end of GOP, controlling IDR insertion with qp file. "Trimming" of .264 file can be done with mkvtoolnix. Since full encode pass require ~6 hours on my HW, it's easier to replace few scenes than do scene-filtering in the script and make fresh encode.

Thank you for the explanation.
