[WiP] madVR support in MP1 (10 Viewers)

[joecrow]

v226 with test3 dshowhelper.
No change with Copy Back and long stop times TVS vid stopped ca 10:07 in attached log.
No change with Native and 4k playback log at ca 10:12

Also sorry but both before and after I added the test 3 Dshow. I noticed a new TV zapping problem with Copy Back only, when switching from a SD channel to HD channel vid will either freeze on SD channel or show a black screen, a further zap either to an HD or SD channel returns video OK, SD to SD zap and HD to HD zap seems OK. See log from 10:17. Native does not have this problem but pq of SD TV is awfull both with Madvr and EVR.

UPDATE
The zapping problem with Copy Back does not happen if I select the option "Use EVR for Live TV", so as a workarround that is what I have done for now, SD pq with EVR is anyway better than Native and Madvr. BTW I forgot to mention it but the audio during the zapping problem does switch to the new channel. it is just the video that does not.

AMD driver version 16.10.3 is available and was used for this testing.

UPDATE2:
I have refined the long stop problem area down somewhat, if I deselect h264 from the codecs to use for HW Accel. in LAV filters, then stop times in TVS and OLV come down to ca 5secs even when Copy back is selected it also seems to have resolved some severe stuttering problems (video only) I was seeing on some 23hz video material. The advantage of this is that I can again use Madvr with Copy Back for TV. HD HEVC TV is not effected and the CPU usuage for regular TV is much the same but the PQ is much better than with Native. I have also reverted back to v222 and the zapping problem, reported earlier, seems to be resolved or at least improved but not sure if that is v222 or deselection of h264.

I get the distinct feeling that all is not well with the RX 4xx implementaion of H264 HW Accel. AMD have acknowledged a number of issues with it but there are many more reported on the Internet and historically they have not always been very open about problems even when a solution is implemented in a driver update. I suspect and hope we will be seeing a fairly rapid release of new drivers over the comming months to resolve issues and stabalise this new range of GPUs. In retrospect I maybe should have gone to Nvidia for HEVC HW accel. but they have such a horrible history with 3D.

Noticed a new oddity while running V225:

- Context menus while video is playing in fullscreen or while in GUI only allow for the first top level menu to open, an example:

AudioSwitcher -> Click button assigned to its context menu -> Will show the top level menu -> Select menu item there like for example "Change Playback Device" -> Should show new menu but nothing happens

If I stop playback it works fine, also affects MP-TVseries and not just dialogs but also navigation between views (All -> Recently aired does nothing for instance) or opening series.
No errors in logs and since it works while stopped suspect something cancelling out those actions as it used to work in earlier versions

For the rest it has been pretty solid so far, crashes have been rare and found something interesting about multi-monitor setups and madVR but not 100% sure this is something Mediaportal related:

- If Mediaportal is on the 2nd (secondary) screen and you have madVR handing refresh rate changes it will not revert back to original refresh rate on playback stop (gets "stuck" at 24P for instance)

Since last Thursday I have reverted back to ver 209 (Ithink, its dated 21-9-16), I used this and it worked well before and after my holiday. This version still looks very good for me, no zapping or other TV issues which I have been seeing with the more recent versions tried and In conjunction with the h264 hardware accel. deselection it looks real good.
One other problem I have is an occaisional green screen, typically after over 1 hours viewing, without pause or stop, this is new with the AMD RX 460 and I also saw it a couple of times with the previous one from Gigabyte but never with my old HD 6670, fix is to stop and restart playback. I am fast loosing patience with the RX 460, just installed a further new driver now 16.11.2, if I don't see some improvement then it may be bye bye AMD.

Kinda quiet here where has everyone gone?

Hi joecrow,

I suggest you to say bye bye to RX 460, it's not good enough for Madvr. RX 470 or RX 480 are both very good and I can do everything with them (upscaling, 3D, etc.): no green screen or other strange issues.

No not gone, but actually no ideas

I can confirm the green screen, but it is rarely on my pc. I would say i see it in 4 hours of playing one time and i saw this green screen with older versions of mp madvr more than now. Driver 16.11.1 don't brought something new.

For the moment i'm on lav: copy back. Looking movies and series over mediaportal and TV over my TV, because with the slow stop it is just unfunny and i don't want to loose hw accel.

Look at driver changelog of AMD:

• H.264 content playback may experience playback issues on internet browsers with hardware acceleration when also running gaming applications or content.

• H.264 content may experience blocky corruption when streaming using P2P content players on some Radeon RX 400 series graphics products.

I hope on updates of madvr, lav and AMD to solve this. I looked a bit around the web, but don't really found people with similar problems. Maybe should try other programs to confirm where the problem comes from. But i'm open for new mp tests

Hi joecrow,

Maybe you can post us your lav, madvr and mp settings of madvr. I can't believe after all tests, that RX 460 is not "good" or powerfull enough. Are you running your pc with 4k or 1080p and which video content did you use for tests? Did you test h264 content playing for 10 minutes and than stop it. How long does it take?

I use my machine as a productive htpc, that is the main difference. If i test shortly the movies or just zap around i have no problems. But if i look an evening tv, series and/or videos, i see the reported problems and the main problem for me is slow stop.

Here too, always watching the thread, but I am very lucky to have had a stable setup with my gtx960.

Something very strange happens to madVR chroma upscaling with 'world of war' TV series, it's a strange issue whereby my SD rendering timings are 10ms, but this program jumps rendering to 35ms! The advert breaks are still at 10ms, so it's not likely to be MP issue.

n retrospect I maybe should have gone to Nvidia for HEVC HW accel. but they have such a horrible history with 3D.

That's my story, perfect HW HEVC but flaky 3d. I resolve this issue by not really bothering with 3d

Same here, got near perfect setup atm with just some small quirks I can live with to have the benefit of perfect image quality

@cabala I am very suprised to hear that, no question that the RX 470/480 are much more powerfull, but the RX 460 is a quantum leap more powerfull than my old AMD HD 6670 and that was good for 3D, HD TV and BD movies using Madvr without green screens etc. My primary reason for buying the RX 460 was to get HEVC HW accel. fot German DVBT2 HD TV (not supported on the HD 6670) as the CPU load without it can peak on my HTPC up to 50% which I felt was bordering on too high, with the RX 460 it does not get much above 10% so that is great but the green screens and long stop times on other content are a major down side.
Are you seeing long stop times (20 secs or more) after playing vids in TVS and OLV or recorded TV programs with the RX 470/80?

No not gone, but actually no ideas

Ah good to know, difference maybe GPU ram size mine is just 2G.

For the moment i'm on lav: copy back. Looking movies and series over mediaportal and TV over my TV, because with the slow stop it is just unfunny and i don't want to loose hw accel.

Look at driver changelog of AMD:

I did not note any significant difference on CPU load after disabling h264 HW accel. and for me the improvement in stop times made it well worth it.

@kenwonders I am thinking of sending the RX 460 back and exchanging it for a GTX 950, which also supports HEVC and I don't think I can run to a 960. I really like 3D so how bad are the issues with MKV/MVC and or 3D disc/image playback with PowerDVD?

Hey
i'm here too but just notice that i wasn't receive not notification for the thread so was thinking nobody answer it lol.
@Rick164 i need to fully understand the dialog screen it seems to be a bug somewhere.

@joecrow
There is a lot of change against V209 and last one but does logn stop appear on V209 too ?
