| Phiro | Switching back to the high quality playback did indeed fix the locking up issue when exiting playback. | 00:17 |
|---|---|---|
| Phiro | So I'm going to guess that the proprietary amd video driver - the updated one - isn't super-cool w/opengl. | 00:18 |
| Phiro | So I watched some videos of video artifacts to figure out what I'm seeing, and I know it's not judder, or what people were calling tearing in PC games, but a vsync issue video was pretty close, so using google, I find this in the mythtv.org site: | 00:28 |
| Phiro | The most obvious side effect of improper timing in MythTV is an effect known as "frame tearing", and can be seen during horizontal pans in scenes or in scenes where there is a high amount of horizontal motion | 00:28 |
| Phiro | and their diagrams seem spot-on with my issue | 00:28 |
| Phiro | Hurm, switching to vdpau might fix this, if my video card supports vdpau? I've never tried enabling it, for some reason I thought vdpau was some sort of external video playback device like a slingbox or something that you feed some signal to. | 00:31 |
| Phiro | What is the preferable order, between normal/opengl/vdpau? | 00:32 |
| tgm4883 | vdpau is offloading of decoding to the video card | 00:48 |
| tgm4883 | TMK, it doesn't have anything to do with opengl | 00:48 |
| tgm4883 | you're talkinga bout different things | 00:48 |
| Patrickdk | I have always found vdpau unusable | 01:20 |
| Patrickdk | as it normally only works with *perfect* streams | 01:20 |
| Patrickdk | any corruption or errors, and they normally go nuts | 01:20 |
| Patrickdk | also vdpau causes funky issues with overlays | 01:21 |
| tgm4883 | It does? | 01:21 |
| tgm4883 | I don't think I've ever had an issue with it | 01:21 |
| Patrickdk | ya, you can't overlay ontop of something that the video card is decoding and doing for you | 01:21 |
| Patrickdk | :) | 01:21 |
| Patrickdk | unless that was changed at some point, to work around the issue somehow | 01:22 |
| tgm4883 | Patrickdk: not sure if you are talking about something else, but the on screen display works fine with VDPAU | 01:22 |
| Patrickdk | is the onscreen display seethrough? | 01:22 |
| Phiro | tgm4883: I know they have nothing to do with each other, per se. I'm having a small problem of horizontal tearing and I tried switching from high quality to opengl high quality, and the problem got less, but the frontend locks up on me every time when I exit video playback. | 01:23 |
| Phiro | So I'm back to high quality, and when I researched horizontal tearing, vdpau was sort of suggested. | 01:23 |
| Phiro | I'm also still somewhat guessing my issues is "horizontal tearing". | 01:24 |
| Patrickdk | oh. looks like overlays do work, now atleast | 01:24 |
| Patrickdk | but seems like it's really finiky though, and if you ahve any kinds of issues, it's recommended to try disabling it | 01:25 |
| Patrickdk | I just use too many non-perfect streams to make vdpau useful, stuff vdpau doesn't understand so can't decode, atsc streams that have errors in it, and all kinds of fun things | 01:25 |
| Phiro | kk | 01:40 |
