It seems that the preallocation is not enough. May be cache with the size of tens Megabytes for each stream in app level is still in demand.

Like I already said, at least 1GB will be perfect. Hoomins who demuxing UHD Bluray have to have at least 16GB RAM, so there is no problem I think.

Yeah, some internal buffering would be good. I make one pass through the source files, writing things as I find them. Making multiple passes would be awful. Internal buffering plus prealloc may be the ticket to nirvana. But first, gotta fix the GUI. Moose and squirrel just finished off a massive fa...

It seems like files have no fragmentation, but while they writes to disk, they are still writes in small pieces, because hdd speed drops from 150mbps to 40mbps. I think it happens because hdd writing small pieces and have to move heads very often between files. I have to check it, but I think if dem...

@redbtn No need for that stuff. Re-download DGDemux_test.rar. It's built with 100/10/1 prealloc. I'm looking into whether we can get a callback when the allocated size is exceeded, with the idea of enlarging the alloc. Then we could start small and increase only when needed. Good! Nice idea! PS: It...

Is it possible to have options like -vbuf -abuf? We have default values, but if you know what you do, you can set it manually.

You drive a hard bargain...for a hoomin!

I'll risk it!
How much RAM uses DGDemux for now? I'd like to use at least 1GB RAM. I can give it 20, but other users possibly can't.

Let's see if anyone else reports your GUI corruption after minimize.

Don't want to get too deep in the weeds on prealloc and make a mess. 10 GB for audio then. Any failure to prealloc is not fatal and the affected streams are just not prealloc'ed.

Deal!

So you say that Windows cannot minimize and restore a dialog? We run 1909. If we come up short on preallocs, people will rag on us. I don't know, I have no issues with my windows, only DGDemux GUI has this issue. I saw TrueHD more than 5GB. You can't do 7-8 GB for THD and DTS-MA, and 1GB for AC3? P...

Can't duplicate that. What OS etc.? C'mon, windows can't minimize and restore a dialog? Don't hand us some WinXP/Win7 nonsense. We use latest libraries and runtimes. I'ma tell Rocky to go with video 100 GB, audio 5 GB each, sups 1 GB. Windows 10 1809. I never saw sup more than 100mb, ok, you can do...

Didn't duplicate it, just keeping an open invesigatory Moose mind. What are your steps exactly to show it?

People call me Inspector!

Open DGDemux GUI. open mpls, click minimize.
Here is a video below.

Looking at your minimize issue.

Sure, let's adjust prealloc as you suggest.

Thx! Can't wait to test it! Looks like you duplicate my issue already, while i was recording a video.

redbtn, don't move the dialog while operations are pending. Rocky will fix it at some point. It happens after minimize, Moving the dialog while operations are pending looks fine. 1Gb for every sub is too much, isn't it? I think 100-150mb is enough. Oh, and how do you measure fragmentation? You can ...

Testing Test version in progress.
Sometimes I have some glitches

Bullwinkle it looks very good! Your intellect is razor sharp!
