--slice-max-size is useful for RTP streaming on clients which insist on slices smaller than MTU. --slice-max-mbs is useful if you need to specify exact slice sizes instead of a general number per frame.

Anyone compiled yet? I'm used to getting my software spoon-fed to me and am getting failed hunks following this guide.

Dark Shikari · 1st September 2009, 00:42

The NAL-HRD patch likely needs updating.

Lyris · 1st September 2009, 00:47

Yeah, that's the one I was trying to apply. D'oh.

Wow, Dark Shikari, you're an amazing guy! You said it was a lot of work, and 2 weeks later we get it! It's the summer of features for x264!

Anything else missing for x264?

I don't think I ever said that slicing was actually that much work...

This is amazing. Thanks Dark Shikari, for the slicing patch.

One question that has popped up when I tried to find a workaround for the unfinished nal-hrd patch: Can I encode without the nal-hrd patch and then run the stream through h264info checking only the "Add Picture Structure" option? Or are there any problems with that method?

Trahald · 25th September 2009, 13:10

As a way to get some software to accept your file maybe. Anything h264info spits out is guaranteed not to be perfect buffer wise because the original stream didnt consider the data being added is buffer calculation. having said that, as long as buffer usage wasnt pinned to max, that shouldnt be an issue for most streams. Best bet will be to wait, but since you are probably just making backups for yourself, you will have to judge if imperfection will be acceptable for you.

moviefan · 25th September 2009, 13:16

Okay, so the patch does not simply add some information to the stream but also influences calculations in the encoding process. I do seek BD compliance rather than the mere acceptance of my stream by some software, so waiting seems the only option. Waiting for a final/corrected version of the patch implies what kind of time range? Days, weeks, months...? I of course don't expect a date, but just a vague estimation... Actually, is there any discussion forum where developers exchange their ideas and where progress of things can be looked at?

Trahald · 25th September 2009, 15:52

IRC is probably the best place right now. #x264dev on freenode
