Yes, I explicitly named HEVC = H.265, because it is used in DVB-T2 HD.

Well if you could provide a specific video to use for testing, I could test it on a few older CPUs including a...

1.2GHz Pentium M
1.5GHz Celeron (Pentium M-based)
1.6GHz Intel Atom (1st generation single core + SMT)
2GHz Core 2 Duo (Merom)
2.4GHz Core 2 Duo (Penryn)
2.4GHz i5 520m (Westmere)

(turns out the previously-mentioned i5 540m was actually faulty believe it or not - swapped it out and now everything works including 1080p 60fps without any random BSoD-ing)

If I include CPUs and PCs that don't currently have an OS, I also have a...

1.73GHz Athlon XP (Thoroughbred)
2GHz Pentium 4 (Northwood)
2.7GHz Celeron (Northwood)
1.6GHz Core Duo (Yonah, not Core 2 Duo)
1.73GHz Celeron (Merom)
1.9GHz Athlon 64 x2 (Brisbane G1)
2.5 GHz Athlon 64 x2 (Brisbane G2)
3GHz Athlon 64 x2 (Windsor)

I believe sneaker_ger may be able. There may be material up to 1080p@50/60fps, probably with limited complexity.

I asked on behalf of people in the DVBViewer and German doom9/Gleitz boards, but I don't have reception without roof antenna, too far away from supported towns.

I'm just thinking, if I'm already using the mixer and I'm playing a 6.1 file, wouldn't the mixer serve the same function as the "Expand 6.1 to 7.1" option.

Could someone answer this? Thanks.

Where? In the UK DVB-T2 HD is AVC.

quick question. I've used MPC-HC for a long time now with lav filters, I set up external filters in MPC-HC as that is what i prefer and it works fine. I wanted to try out MPC-BE and I did the same thing adding the external filters and turning off all internal filters yet it is using Lav splitter and Lav video but won't use lav audio. Is there a special way to setup mpc-be?

Prog add MainConcept HEVC Video Decoder support in its Demultiplexor

Is it difficult to add it in LAV Splitter?

In MPC-BE 1.4.4 (build 286) under XP I unchecked all in Audio Tab Internal Filters and add LAV Audio set point to Prefer:

What do you like MPC-BE for?

LigH · 27th July 2016, 07:24

@ VictorLS:

You want LAV Splitter to "support" MainConcept HEVC Decoder ...

a) LAV Video Decoder can decode HEVC too, what else can MainConcept what LAV Video Decoder cannot?
b) Does MainConcept need a specific support at all, e.g. a special authentication, to be used in DirectShow filter chains? If not, I guess you could just disable HEVC support in LAV Video Decoder, and DirectShow shall connect to the next available filter?

HEVC is being used for the new DVB-T2 service in Germany - only test transmissions at present, but the full service is due to start in May 2017 (AFAIK).

From the test recordings I've played with, it's mostly 1920 x 1080p @ 50fps, around 2 - 2.5 Mbps e.g. -

Code:

BE does stereo scopic subtitles and they work using madvr for rendering MVC 3d.

I have not strong enough computer to decode h265 3840x2160p60 10bit smoothly (h265 1920x1080p50 I can watch absolutely smoothly using CyberLink Video Decoder (PDVD Generic) with 20% load of each three cores of my CPU and using LAV Video Decoder with 50% CPU load). So I wanted to see slideshow h265 3840x2160p60 10bit directly from SATs but LAV Video Decoder can not decode I-frames only - I strongly asked nevcairiel add this feature in LAV Video Decoder two times earlier but (((
Also I asked Cyberlink - they are not answered me at all. Elecard HEVC Video Decoder decodes recorded on HDD h265 3840x2160p60 10bit perfectly but directly from SAT - decodes well 8bit only.
MainConcept HEVC Video Decoder can decode I-frames only with SkipPB settings in DVBViewer many times ago and in ProgDVB from yesterday, because I think MainConcept HEVC Video Decoder has non-standart pin which can connect to MainConcept's MPEG and MP4 Demultiplexer, but can not to LAV Splitter, so I can not use MainConcept HEVC Video Decoder with i.e. mkv files before nevcairiel add support of MainConcept HEVC Video Decoder in LAV Splitter.
PS. I don't want to keep many demultiplexers and decoders in my WinXP and Win7x64 )

Maybe nev can retire CUVID decoding since Nvidia doesn't support it much anymore and it doesn't work on Win10 anyway, prefering a unified SDK approach with Nvidia Video Codec SDK 7.0.

wawa79 · 31st July 2016, 17:42

Hello,
Until today, I have been prefering FFDShow audio to LAV audio in my Mediaportal CODEC settings.
The reason is that I never managed to get LAV audio to output Dolby TrueHD 5.1/7.1 as multichannel AC3 to my SPDIF output (my 5.1 AVP has no HDMI / HD audio): I tried the last 0.68.1 version, I tried to enable mixing and in best case, I only get 2.0 (despite GraphStudio status shows 8 channels IN and 6 channel OUT when I use LAVF

)

FFDShow properly handles direct 5.1 TrueHD output and downmixes 7.1 TrueHD (using its Mixer panel) and reencodes it as AC3 to fit my SPDIF output.

My life with FFDShow was peaceful until Dolby's marketing decision to release Dolby Atmos to public. FFDShow just get stuck on these streams so I cannot use it anymore. And because Atmos is the default stream selected when starting playback, there is no way to play these streams from MP...

I found a workaround which is to setup LAVF audio as the decoder and add FFDShow as postprocessor but I am pretty sure that I am missing something to properly setup LAVF to handle properly TrueHD on my setup... or that there is definitely a bug.

Could anyone help me?

Thank you in advance!

But

They didn't change anything, its still the same thing in a new zip file.

PeQuE · 3rd August 2016, 09:06

I've searched all thread for the word "EXIF" and I only found two posts dated at 2012, which have nothing to do with what I want to ask, so here we go...

I know EXIF metadata has been used to "declare" picture orientation for many years... What I didn't know is that videos (at least .mov and .mp4 ones) had also this EXIF info. The fact is that both smartphones currently at home (IPhone 6s and Nexus 5X) uses "Rotation" EXIF tag to declare actual orientation for videos taken with them...

The question is: who in directshow filter chain is responsible to process this info and finally play correctly oriented video? splitter? video filter? player itself (if it has any sense)?

My currently set up is LAV Splitter + LAV Video inside MediaPortal 1, and it's failing at playing this videos correctly: vertical ones taken with IPhone 6s, all of them taken with right hand using Nexus 5X, because the're all tagged with rotation=180 as sensor is upside-down mounted for space matters for this smartphone.

Thanks a lot.

sneaker_ger · 3rd August 2016, 09:31

LAV can read and pass on such rotation info but leaves the actual work to the renderer. madVR should support rotating.

PeQuE · 3rd August 2016, 10:19

Wow! So it's renderer which does the job?!

I'll tesd madVR then...

Thanks a lot for the info.
