problem changing pot player filter

[hd7970]

Hi I just bought Coreavc decoder from their site but when I scan and then load the filter every thing ends up squashed and of really bad quality this is also the same when I load the divx H.264 decoder or the divx decoder filter it just looks absolutely terrible I really hope there's a way to fix it because I realy wanted to use these filters. Please help.

I'm a little confused. Did potplayer work OK before? It uses its own internal codecs, as it should be. It shouldn't need 3rd party codecs. No player should. How about other players?

What are your hardware specs? For example, if it's a single core machine no codec will make it play 1080p video properly.

Also, "divx H.264 decoder"? That makes no sense to me. Those are 2 separate codecs. You can't use both at once.

You may not want to hear this, but I wouldn't touch 3rd party codec packs on a windows 7 computer. Microsoft recommends not installing any of them on their tech support site. I'd uninstall that stuff and then run codec tweak tool to make sure every codec is using the microsoft filters.

Actually I suspect you may have other 3rd party codec packs installed and there's a conflict there somewhere, which is why microsoft specifically says not to install them.

I don't use windows 7 much anymore but when I did I yanked all 3rd party codec packs and only used media programs that used their own codecs and thus didn't screw up the windows registry. For video players, in order of preference, that was smplayer, vlc, and, yes, potplayer. Potplayer has excellent playlist features but I found its video performance lacking.

Yes pot player works fine and I think its great its just its built in h264 codec looks like crap.

My cpu is a 3930k .

The DivX H.264 decoder Im pretty sure is just the video codec DivX plus uses to play HD video. I don't actually want to use them all at once just one at a time.

I agree with you there but unless you download certain other codec a lot of stuff wont play in DivX so I had to. I have Vlc as well and its my opinion DivX is pretty far ahead in picture quality.

Are you aware of the feature Pot player has to change Video codecs?

[jagabo]

Divx Corp. now makes both Mpeg 4 part 2 (the old Divx/Xvid) and MPEG 4 part 10 (h.264/AVC) codecs (they bought MainConcept's AVC codec). And is beta testing an h.265 codec. A single core CPU can play 1080p video if DXVA (GPU decoding) is used. In any case, an i7 3930k isn't going to have problems with 1080p h.264 CPU decoding. There might be issues with DXVA compatibility though (ie, the video isn't DXVA compatible).

There's some kind of miscommunication between CoreAVC and PotPlayer. Have you tried fiddling with CoreAVC's settings? Make sure it's in use by enabling its Tray icon. You can select configuration options from that icon.

[hd7970]

Actually its the Avc1 codec change that cause the problem. Also I shouldn't say pot players codecs are crap there pretty damn good its just the coloring and shadows always seems off.
So has anyone changed codecs and had this problem before? see first post.

Just a note here on PotPlayers settings. There are a ton of shortcut key alterations to brightness, sharpness, etc that like to get set by "Finger Checks".

There is a reset, I believe it is the Q key by default, and reset all to the video defaults. Some may just have accidentally gotten set and causes the bad look. Just a thought...

That's probably not a decoder problem but a video proc amp issue. I don't know of any h.264 decoder that decodes with "wrong" levels except Quicktime. Slightly off colors may be a rec.601 vs rec.709 issue. Again, that's not a decoder problem but a colormatrix issue. Either the codec not communicating the colormatrix correctly or the display driver not paying attention to it.

Hi I have actually managed to get the coreAVC codec working with the 64bit player so that's something. It looks a hell of a lot better now.
still cant get other codecs working with the 32bit version buts that's ok for now.

jagabo - So what could be rec.601 vs rec.709 issue be. could fixing this help off colors? I get a lot of green on peoples faces on blurays.

Budman1 - Yeah its got a great amount of features and tweaks. the new Coreavc codec is great to. But I cant actually find a sharpness setting?

[Budman1]

Video processing filters are turned on by right clicking and going to Video -> Video Processing. CTRL-R is the sharpness default. But to find them and adjust right click screen and go to Video -> Video Processing -> Video Processing Settings:

To reset navigate again or hit the Q key

Literally green? Or just tinted a little greenish? The latter might be a rec.601 vs rec.709 problem.

Thanks budman1.
Jagabo -I had a look at that post and changed a few things didn't seem to make a huge difference its seems to be manly with skin tones amd has a setting you can use to after it but doesn't seem to help much. here is a picture of what it looks like it looks worse when its actually playing .

That's probably a graphics card driver problem, not a player or codec problem. When a media player plays a video it decompresses the video to YUV and gives that YUV to the graphics card for display. The graphics card converts the YUV video to RGB before sending it to the monitor. It chooses what matrix to use for that conversion, typically rec.601 or rec.709. It can decide on which to use based on information give to it by the player (the matrix can be specified in the video), or it may assume rec.601 for SD, rec.709 for HD, or it may just pick arbitrarily. As it performs that conversion it may also use its video proc amp to adjust brightness, contrast, colors, etc. It's also possible for the player to adjust the video before handing it to the video renderer.

Note that players have several choices of video renderers (the software device used to get video to the screen). Some work better than others and they may have different processing. Different players may default to different renderers.

So you need to control for all these variables.

[hd7970]

hmm interesting you wouldn't happen to know how get that control for pot player? Also if it helps it seems to happen only when playing through pot player and power dvd when playing in VLC the issue is non existent

[hd7970]

Hi I fixed it thanks for all your help

[jagabo]

Look in the Video section of Potplayer's preferences. Also calibrate the video proc amp in your graphics card's setup applet.

What are your hardware specs? For example, if it's a single core machine no codec will make it play 1080p video properly.

I guess if it's single core machine there's a greater chance it has a fairly old video card or basic mother board video, but I assume you're familiar with hardware decoding, or DXVA, or whatever you'd prefer to call it? Well maybe not if you use SMPlayer. Does MPlayer support hardware decoding yet?
The closest to a 1080p video I had handy was a 1920x816 encode. I ran it on my old dual core (E6750) courtesy of MPC-HC and CPU usage varied between 5% and 10%. Well I guess there's also audio decoding to be done and there were a couple of background programs using a little CPU time.
Seriously..... my Android smartphone can play High Profile, Level 4.1 at 1080p without a problem, although admittedly I don't use SMPlayer there either.

You may not want to hear this, but I wouldn't touch 3rd party codec packs on a windows 7 computer. Microsoft recommends not installing any of them on their tech support site. I'd uninstall that stuff and then run codec tweak tool to make sure every codec is using the microsoft filters.

Actually I suspect you may have other 3rd party codec packs installed and there's a conflict there somewhere, which is why microsoft specifically says not to install them.

I'll ask.... is Potplayer one of those players which doesn't need to use "system" codecs (ie DirectShow) as it uses it's own, or is it a little naughty like MPC-HC and comes with it's own but also lets you use system codecs instead? Because even if it's able to uses system codecs, while it's not....... isn't that the entire basis of the "don't install 3rd party codecs" argument? Use a 'self contained" player. I'm just wondering what could be causing conflicts to arise when running a player which doesn't use any of the 3rd party codecs which could cause them. Could Potplayer be self-conflicted?

Microsoft made it harder than it previously was to change some of the Windows default codecs/decoders, so no doubt they tell people not to install any to save themselves some tech support, and no doubt also confident the decoders supplied with Windows are all anyone will ever want to use, which of course is nothing to do with making life easier for Microsoft.

Potplayer is like MPCHC -- it comes with its own internal filters but lets you use DirectShow filters instead if you want.

Because even if it's able to uses system codecs, while it's not....... isn't that the entire basis of the "don't install 3rd party codecs" argument?

There's nothing wrong with installing 3rd party codecs. That's the whole reason DirectShow allows you to do so. How else are you going to play a video for which the player doesn't have a codec? The problems arise when you install full mega codec packs which contain multiple conflicting filters -- especially when someone install two or three codec packs.

I agree. I was just hoping to resolve what appeared to me was a 3rd party codec, confliction paradox.
