[SOLVED] [mpv] Fallback to software decode SLOW with vo_vdpau/vaapi

aphirst · 2013-09-21 23:08:45

EDIT 02/01/2014: Since mpv 0.3.0, the opengl renderer, which works perfectly fine with software-decoding, now also works with vaapi/vdpau hardware-decoding, so just setting vo=opengl and hwdec=auto should really be enough to utterly avoid the problems I was having back when I made this post. A lot of the "info" I gave later on in the thread is also actually bogus, I'll tweak that in a second.

---------------------------------------------
I've been reading the documentation for mpv, and there's something I can't quite figure out.

My CPU isn't especially powerful, so it's important for me to be able to use hardware acceleration where possible. I'm using the proprietary ATI driver; VLC works fine with VA-API, and since I discovered libvdpau-va-gl I've been able to get mpv to work using VDPAU. Obviously, some files (*cough*, Hi10P, *cough*) can't be hardware-accelerated, and this is where my problem/question comes in.

In my mpv config file, with

vo=vdpau

I'm able to play normal h.264 video effortlessly, but when HWaccel isn't available mpv falls back to software-decoding and software scaling (ffmpeg/swscaler, as per the console output). The problem is, with the CPU already working to decode the Hi10P content, my A-V desync skyrockets, and it's all a bit of a mess.

If I play the same Hi10P file with

vo=opengl

, then it doesn't desync at all. I checked the manpage and it says I can concatenate possible video outputs with a comma, and it will try each in turn. Obviously I'd like the not-hardware-decodable content to be rendered using OpenGL, rather than whatever causes them to get fed to "swscaler". So I set the config line to

vo=vdpau,opengl

. However - the opengl option never gets used! The non-HW-decodable files still end up being fed to swscaler, and as a result desync wildly, unless I manually set to opengl for that file.

Is someone here familiar enough with mpv to be able to explain why I might not be getting the behaviour I expect from listing multiple video outputs in the config file; or even better, how I can configure mpv to do what I actually want?

If there's somewhere else I should be asking this, please let me know. I couldn't find a dedicated mpv forum or anything (or even an IRC channel for questions), but I could have missed something.

Addition: Here are some console outputs.

1) Playing an 8-bit h.264 file with vo=vdpau, works fine

I don't know how to solve this, but I can say, that the author of mpv was very responsive and helpful on IRC when I had a problem. I'm sure he'll know what to do!

Please post the solution here!

Roberth · 2013-09-22 12:41:26

You need to define hwdec=vdpau for example also.

kaszak696 · 2013-09-22 13:14:53

While it's not a proper solution, you can try to use sws=0 option, it uses a faster scaling algorithm.

aphirst · 2013-09-22 13:48:03

So, I had a nice long conversation last night with some of the devs on the IRC channel (that I didn't find first-time-round somehow). I'll summarise this in bullet points:

>I'm using an ATI card with the proprietary driver
>I'm exposing VDPAU via a library that uses VA-API underneath
>the vo_vdpau mode for mpv continues to handle file playback even if the vdpau hardware decoder won't initialise
>>i.e. vdpau itself calls the software decoder, and then handles the calls to a software renderer
>because I'm using VDPAU in an indirect "wheels within wheels" library, it's slow as all hell

Solution:

UPDATE: READ THE POST BELOW, A BETTER SOLUTION HAS BEEN IMPLEMENTED
>mpv-git has native VA-API support, vo_vaapi
>compiling and using this works perfectly
>the vaapi handler is able to much more efficiently handle the calls to software decoders/renderers
>8bit h.264 files play fullspeed using hardware decoding
>10bit h.264 files are automatically handed to software-decoding, and play (almost!) as well as they should (i.e. when directly calling vo_opengl or vo_xv)
Note that it's still a little slower than using opengl or xv, which is kind of odd. wm4 on IRC mentioned he might be able to do something about this, by implementing the (hackish, apparently) thing that VLC does, so that vo_vaapi doesn't have to use swscale (slow) before rendering; but I'll wait and see if that pans out.

TL;DR - People using the proprietary ATI driver should compile mpv-git and and use vo=vaapi

@Roberth: I actually did have that enabled, but whether it was or wasn't enabled didn't affect the problem I was having. After all, the problem was with vo_vdpau calling software decoding in an inefficient, roundabout way. vo_vaapi still isn't as efficient at this as it should be, it seems, but it's better than vo_vdpau was on my setup.

@kaszak696: As far as I was aware, sws=0 was the default behaviour, but I do recall forcing that at one point with no effect. Either way, my particular problem is solved/worked around now! Well, almost.

EDIT 02/01/2014: The readback functionality is now basically deprecated, if you use vo_opengl and vdpau (FOSS AMD) or vaapi (Intel) hwdec things should "just work". I think vaapi (Catalyst) still has some use for the readback (the vaapi-opengl interop is mesa only, I think), but I wouldn't be surprised if that changes.

-----------------------------------------------------------

A more full solution has been implemented by wm4 in the branch vaapi-readback, which allows vo drivers like opengl to access the hardware decoders, by copying decoded frames back to RAM. I think that's how it works, anyway. Either way; it does definitely work.

If you build the mpv-git package from the AUR, and change master to vaapi-readback; and then set --vo=opengl --hwdec=auto when running mpv; then all these problems disappear, and the automatic handling works in the way I had initially assumed it would, with the performance to match.

wm4 insists that doing things this way is intrinsically inefficient, and that his current implementation is also less efficient than it possibly could be. He(she?) says that using this copyback method will probably actually be slower on desktop machines; but I imagine that on netbooks/nettops with weak CPUs (but with hardware-decoders), this is just the ticket. I'm happy, at least.

I think it was also said that this may find its way into the main branch, but then the IRC discussion went to discussing the "proper" ways of doing this with vaapi/vdpau, and I imagine that's where most future effort will (and probably should) go.
