OBS branch with AMD VCE support.

having 0 issues has nothing to do with why we need to see logs; something OBS might not report since this is a custom build of OBS

did I ever say this? I stream at 3500 right now, I said that your stream was peaking 17,000 bitrate (i.e. 17Mb/s) and averaging 5,000 bitrate which twitch does not like. OBS and VCE will stream whatever bitrate your PC can handle

http://www.twitch.tv/d2_ricci/b/587516476 this is me streaming at 720@48fps. its not perfect but its a work in progress.

Last edit, I promise: your game that you are streaming has A LOT of shrubbery (plants, grass, trees), video deciders have a lot to decode when small particles are being encoded so dont expect a perfect picture from that game.

your video looks pretty good, what was your settings? if my stream was 17k bitrate that can i lower that somehow with amd vce? Do you know how to fix my issue with Amd VMF because i'm completely lost in that regard. I just want my stream to look acceptable or look like other people stream like lirik or total biscuit, they stream at 1080p/60fps and their video looks very good for 3500bitrate

The reason why you were streaming up to 17,000 bitrate was because OVE overrides the bitrate set, switch to AMF. Ensure that http://www.microsoft.com/en-us/download/details.aspx?id=40784 you get the version of MS CV++ that your OBS is set to, i.e. 32bit, 64bit. having one doesn't mean you have the other.

I already posted my settings above. https://obsproject.com/forum/threads/obs-fork-branch-with-amd-vce-support.13996/page-55#post-110219

Also, would you mind please posting a log file after you change your settings?

Are you using windows 8.1 32bit or 64? if 64, have you tried the 64bit version?

Scene buffering: change to recommended 400ms. this isn't at fault but will cause some AV sync issues or dropped sounds IME.

for "AMFCreateComponent(encoder) failed. 35" Jackun said to a post a while back to make sure you have the most recent drivers, uninstall AMD drivers using DDU and reinstall the most recent version you can get DDU from here:http://www.guru3d.com/files-details/display-driver-uninstaller-download.html

http://support.amd.com/en-us/download/desktop?os=Windows 7 - 64 I use 14.9, not the beta since this one works great.

Sepay, I am still reading through this, TY sir, I will EDIT this post later for you :D

If you are doing 30fps then set IDR to 60 (or 0 with newest version of OBS-VCE) and GOP to 15
If you are doing 60fps then set IDR to 120 (or 0 with newest version of OBS-VCE) and GOP to 30
If you are doing 48fps then set IDR to 96 (or 0 with newest version of OBS-VCE) and GOP to 24
etc...

I was watching your stream, no lagg at all, but a bit of bitrate variance, it was dipping down a bit but you seemed like you were alt tabbed

Not bad.

x264 CPU preset medium - this does nothing with VCE by the way. might as well set it back to normal

using VBR, interesting....

IDR period 30 I would set to 60, you have to many I frames and not as many P frames with IDR set to 1 second; it will probably improve quality if set correctly at 2 seconds (i.e. double your fps)

somewhere in the first builds of obs vce the cpu preset did work for me so thats why i changed that ;p
i wil try that with idr period.
however this is a very good start, veel free to tweak and let (us) know what you did, with a youtube video please ;)

not anymore so you can leave it default
running obs on 2 cores did gain me quite a few fps in game tho (again not sure if that's still the case (but worth trying!))

ok, so i was discusing thes problems with guys on live chat, they said that it will not be wachable for many people, becouse of buffering issue, for me it buffers more than shows actual footage. Most important for me is to not get grain on my stream. Oh, there is a strange thing happening, in game, there apears like colorful pixels on my screan usually in sape of cubes, but in streamand alttabed they dont show, happened today couple of times.

I watched your stream for 20 minutes, live. it looked fine minus your IDR was set to low, seem like it was set to happen once a second (i.e. IDR = FPS), set it to double

the fuzzing on your video is the IDR frame refreshing which is needed for streaming, only 1080@60 needs more bitrate for that IDR (since its an unreferenced frame).

I dont know where you got IDR 128 from, its set to double the fps, i.e. 120. as for QP settings, I set mine to min:18, max 38. I get a bit more over the max bitrate but it looks better to me and others.

If you are doing 1080@60fps, your bitrate needs to be around 5000 minimum, and is why it is not advised to do 1080@60fps, twitch doesn't support over 3500 bitrate, so you've been advised. Do 720@60 or 720@48 which is what I use. lastly, try (just for S&G, balanced preset, then use r1ch's stream analizer, should be better, but I still would set your bitrate to at least 3500
read the notice you get from R1ch's site:

Streaming at 1080p60 or higher is not recommended as viewers may be unable to watch your stream due to the high decoding requirements.

720 is watchable on most mobile devices plus doesn't stress out the viewers computer while he watches/decodes your stream.

1080@60 fps will tax both the CPU and the majority of internet connection with the bandwidth/bitrate needed to decode it.

Will higher fps result bad quality?

sneaky4oe · Nov 18, 2014

I see that there's a newer version, but when I was streaming with a previous one (profiling code removed) I still had random bitrate spikes from 6 to 8mbit/s and even to 14 at some points.
And a few times something crashed, and I had to restart the game and OBS to start streaming again.

Also, OVE still doesn't work for me. HD7870

dping · Nov 18, 2014

Sepay said:

Yes and no. higher framerates at the same resolution at the same bitrate will look smoother, but for that smoothness, you lose quality. often that quality is made up for because the eye has more frames and tends to blend the moving picture together.

this is comparing actual x264 (veryfast preset)
Lets take 720@30 and 720@60 both with 2000 bitrate.

The 720@30 will looks great (since this is the "quality" bitrate for that resolution), but not as smooth since 1 of 2 frames is dropped (like a youtube video).

While 720@60 will obviously looks super smooth yet will be pixelated since 2000 bitrate is super low for this resolution.

Know though when going from 720@30 to 720@60, you do not need to double the bitrate due to the above affect. I would say 1.5x when doubling the fps.

Lets take that same calculation with 1080@ 30 and 60. 1080@30 needs 3500bitrate (twitch's "max") to look somewhat quality. so that will mean that 1080@60 will need 5250 bitrate to look similar. and that is on x264.

More to come...

you using OVE still?

Anyway, read two pages back, I had to slightly underclock (using default clockspeeds) and set power limit to 20% which helped with any all crashes. OCCT was showings errors during stress tests almost a few seconds outside of testing with default clocks. those errors are often correctable and not always visible in game, but could easily crash a driver when to many occur. I would do the same baseline as me. I think CCC tends to try and overclock everycard to get "max performance" but doesn't check to ensure the overclock is 24/7 stable.

So this,I believe, is the best posible what i can get out of my baby. 30 fps resolution 1366/768
Twich stream vod

Setings:
Encoding tab

Use CBR, (enable)
Enable CBR padding, (enable)
Use Custom bufersize(3450 max bitrate and buffer)

Advanced tab (I think these doesnt matter much but what the heck, calling out what might matter)

Use multithread Opt. (enable)
Process priority class (above normal)
Scene bufering 400
Use CFR (disabled)
Network: Automatic low latency mode (enable) Bind to interface-default, Latency tuning factor 20

AMD VCE encoder tab

Use custom parameters (enable),
CABAC (enable)
GOP (15) IDR (60)
Do NOT use blahblah (uncheck)
AMD AMF settings (quality, DX11, minQP 18, MaxQP 51)
