firefox must use directshow filters on windows xp though, right?
so maybe you can force all windows builds to do the same. also, there are plugins that allow you to download videos off youtube, so you can do that and just put the video in a directshow player. Last edited by mindbomb; 15th May 2013 at 00:27. |

Edit: btw it just occurred to me... now it is possible to create skinnable video player and watch stuff not only from internet but from harddrive. And it could be just a webpage, not even a plugin. If i Just want to watch h264 in firefox, I can right click -> open with, or simply drag'n'drop... I take my words back, we need LAV in firefox ( ´∀`) Last edited by Keiyakusha; 15th May 2013 at 10:04. |

Hello Nev.
There are some minor glitches when using LAV Video Decoder with DVBViewer (and not only): 1. At the start of the program is such a picture appears on the screen. The sound keeps going normal, but this picture remains until I switch the channel. Only after it appears normal picture. It happens with each program start. 2. If there is an error in the video (due to DVB-stream failure or etc.), the image freeze at this moment, the sound keeps going normal, but then nothing changes until I switch the channel again. Sometimes it happens with other players that use LAV Video Decoder (eg PotPlayer, etc.). I want to note that the similar stuff does not happen when using other decoder (eg Microsoft DTV-DVD Video Decoder). Thank you for your attention to my question.

It'll be included once it hits mainline libav/ffmpeg, i'm not in the mood merging and maintaining the patches manually.

The decoder works with surprisingly many things after elenril's touches to it, and I could get 30fps raw decoding speed with its current stage (not much optimization or any multithreading) on a 2.26GHz C2D with 720p content. But as soon as you bring up something else than straightforward A→B decoding, you'll see that there's still a lot to poke and fix.
First of all, seeking does not work. Second of all, because every NAL unit is handled like a packet, ffms2 f.ex. will see at least three extra frames at the beginning of a clip (SPS, PPS and VUI). So merging it into LAV's ffmpeg repository does not exactly make sense right now. Not to mention that there seem to be some differences between libav's and ffmpeg's certain H.264-related files that smarter's decoder touches (CABAC stuff etc.), so one would have to make some manual merging for it to happen, as well. The OpenHEVC project that GPAC's media player (Osmo4) uses for HEVC decoding also bases on smarter's code, and their useful changes do get merged back into smarter's tree every now and then. They do seem to be rather forgetting about the fact that they have an upstream, though, as, if you tried merging their changes in without any poking, in many cases you wouldn't even be able to compile it. They are completely coding their additions for their C++ thingy it seems . And I think I'll stop here before I get down to my usual ranting about GPAC's other "fun things" :P .

Cannot be done, the driver doesn't support it. Use DXVA2 instead.

NVidia CUVID with DirectVobSub
Hi
Great program, thanks for writing it! It works really well for me except for subtitles. I've used MKVMerge (header editor) to flag the forced subtitle tracks but they still don't show up in Windows Media Center. So I loaded up directvobsub 2.41.7036 and the subtitles show up! But... CPU usage goes through the roof! It would appear that DirectVobSub breaks CUVID acceleration... Am I doing something wrong? I'd love to have working forced subtitles in Windows Media Center (native player) with CUVID working. Thanks |

I certainly have set hardware decoder to CUVID in the LAV Video settings and when directvobsub isn't installed CPU usage drops to <5% for the most part. The HTPC uses an 8600GTS and the desktop (which most of the testing is done on) a GTX 260 The HTPC is about to get an upgrade, probably to a GT 640 though |

I ran graph studio (attached) and it seems to be using Microsoft DTV-DVD video decoder... If I go to: Filters-> Manage Favourites -> Add Filters -> LAV Video Decoder -> Insert after deleting "Microsoft DTV-DVD Video Decoder" I can then arrange the video stream to go through LAV. It plays fine through GraphStudio but then how do I save this so it is default behaviour? The merit for Microsoft DTV-DVD is 0x005fffff The merit for LAV Video Decoder is 0x00800003 Hope this helps someone to help me! I tried XY Vobsub... Didn't make any difference unfortunately |
