User experience with AMD 780G and MediaPortal (3 Viewers)

[Lucky_JL]

I know that MPEG2 is easy ( even Software Decode ), my MPEG4 issue is with subtitles problem ... HDTV rips come in .avi containers so to use subtitles i have to read them from a .srt file, if i enable DVXA on HDTV rips i will lose my subtitles right ?

On HD rips ( 780p, 1080p ) the container is .mkv who supports internal subtitles, so i guess that i can use DVXA and still get the internal subtitles, i only lose the external subtitles like .srt files, right ?

I have no experiences with subtitles, but I think it´s all the same if the sub is in the container or comes from a separate .srt file. Both of them must be added as postprocessing, so it can break DXVA.

btw I could playback Bluray 1080i h.264 24p with subtitles with PDVD, with DXVA. So my theory is valid only for MP maybe.

Since you can playback with subtitles using PDVD that proves that is possible
I supose that your *.mkv have some type of subtitles right ? It is possible to test if you can watch the movies with some kind of subtitles ?

Thanks,

I have now discovered that even my PowerDVD8U stand alone programme will only accelerate AVC and not h.264 so this was not a specifically MP problem as I thought. DXVA still won't work for me in MP for AVC but it does work in DVBviewer using the PDVD8U decoder. MPC-HC will accelerate h.264 files but AVC files don't work properly. Can you explain how to get MP to load MPC-HC as an external player as I tried to just link the .exe but MPC-HC crashes? Can I get it to just load h.264 .mov and .wmv files and not AVC encoded files (.ts recordings)?

Sorry, I made a mistake in my last post as I thought AVC was different to h.264 when it is actually the same thing. It appears the difference between what is and what is not accelerated in PDVD8U is progressive h.264/AVC doesn't use acceleration whereas interlaced h.264/AVC does.

You asked how to use MPC-HC as an external player.

You have to pass on the filename, i can't remember the string to use but it is something like %file_name%

So for external player put

"C:\Program Files\MPC-HC\mplayerc.exe" %file_name%

it might be $filename$ or something like that, it has the parameter in MP Config.

You can also pass on parameters such as start in fullscreen and close when finished playing, you can find a list of the command line shortcuts within the MPC-HC program.

Thanks I tried this but I get an error associated with quartz.dll when I try to open .mov files which play fine if I open them in MPC-HC. AVI and .wmv files seem to work OK.

Sorry to keep asking the same question but could someone check out this posting on registry settings in the german forum and see if it can be useful to get hardware acceleration working with mediaportal?

UPDATE: I tried re-registering quartz.dll- this fixed it for 720p .mov files but 1080p still cause a crash with the same quartz.dll error.

there is data on trying different versions of quartz.dll in the wiki. you need to also download "replacer" to swap the .dll as unreg and rereg wont actually change it apparently. i however did not need to do this fix.

I checked and I have the latest version of quartz.dll so maybe mine has beren corrupted somehow? I am thinking I may just reinstall anyway so hopefully I may lose a lot of these problems.

However, before I reinstall... I have been playing around with using PowerDVD8 and 7.3 and it appears, at least under XP SP3 and using 8.10 Catalyst, that PowerDVD8 will not accelerate progressive h.264, it will only do it for 1080i.

PowerDVD 7.3 accelerates both 1080p and 1080i h.264, but neither 8 or 7.3 will accelerate a VC1 1080p Dark Knight trailer which will work with acceleration in MPC-HC. On my reinstall I am going to use Catalyst 8.8 which is the latest version approved by Gigabyte .

Some off-topic ( or maybe not ) question!

In this thread i had explain my current HTPC plan, my question is that some one can give me some feedback to this question,


Using a 4850e underclocked/undervolted so it runs at 1.5GH it, 4GB RAM, with J&W MINIX 780G it is possible to decode by software 1080p sources ?


I know ( and i wanted ) that mosted of the decode goes by hardware, but i want to be safe that when for some reason ( configuration problem, wrong encode level, drivers... ) the system cannot use DVXA then we use the CPU and do the decode by software ( of course all this in a transparent way to the user )


Thanks,

IMO that would stutter with panning 1080P shots even if using coreavc

If i use software decoding with 4200+ CPU i get stutter on some panning landscape shots with resident evil 1080P mkv file.

 

[Lucky_JL]

lol

Thanks for the feeback, it's also my "feeling" that 1080p at 1.5GHZ don't work
Anyway the plan is to run the 1080p content with DVXA, and for that i think 4850e @ 1.5GHZ is more than enough, so i my previous question changes to:

Using a 4850e underclocked/undervolted so it runs at 1.5GH it, 4GB RAM, with J&W MINIX 780G it is possible to decode by software 720p sources ?

Anyone ?

The title of this thread is that 780g chipset is bad for Mediaportal. Is that still valid? Sorry but reading the whole thread and getting the aswer if every issue found is solved or not is really hard.

So, is it good?
