A surprising discovery

[sam9s]

Oh!! in that case VLC should not be able to play .....NOT because VLC cannot (it can) but because files are AACS copy protected, and cant be played by just copying or ripping ...... I am genuinely surprised they were played.

Anyway the post might be of use to someone .....

Sorry to hijack your thread venkat. No wonder venkat is the moderator here... Noobs (including me...) should be careful when trying to explain things to venkat. Hopefully he would bring up something only if its got truly a value...

There is a saying in Telugu "Taataki Daggulu Neerpinchadam" - translating to "Teaching a Grandpa how to cough" hyeah:

I tried the settings as per the link posted.There is another link which has a lot options,tried in past but cant understand the details-

yeah seems like that they are using custom settings with the third party decoder..

guess it should work..

i got nvidia 7950gx2 .. vlc never worked with 1080p

my friend's cpu is a monster.. costed close to 60k .. it played 1080p flawlessly.. but
it stuck when we selected audio channel as spdif so we can get dts over the logitech z5500

 

[theironhorse]

i will try these things today.. lets see if that works.. i will update also i will try diff combo's too what can be done to get better results..

I can see rich colours(sometimes unwanted),sharpness doubles with shaders.
Overall image looks better ,but need to adjust as per taste.

I have a very simple computer with onboard video & 1GB RAM. I tried a zillion players, vlc, mpc-hc, splayer, potplayer, splash player, windvd, tmt, gom player, KM player, mplayer, kantaris......what not. All of them gave jerky playback with some particular 1080p files with DTS-MA & DD-THD. One such notorious demo clip is "hd_dolby_city_redux_lossless.m2ts". This file can be found on the web. Only two players succeeded on playing them without jerks. One is PowerDVD and the other is BS.Player Free v2.57 with the Haali media splitter v1.10.262.12 that it downloads & installs by itself at the end of the installation.

I tried using Blu-Rays with VLC, and have the following results.

1. As long as the media on the HD is an exact duplicate of the disc (with sub directories and files), VLC plays most Blu-Rays happily.

2. Irrespective of what you do, VLC does not play an ISO copy of a Blu-Ray. Even if you mount the ISO as a drive.

3. In spite of whatever preferences you set, VLC sends audio as PCM which the receiver sees as Multi Channel. When the movie is playing and your right click, you get a set of options for audio, video, etc. In that if you choose audio device as 'A/52 over S/PDIF', you get bit-stream with full DTS and Dolby Digital. Every time you change the movie or shut down and restart VLC, the audio device resets itself back to stereo and PCM. These could be machine/driver specific and would need more research.

4. I inserted a copy of 2012 into the Blu-Ray drive. After shutting down PowerDVD that auto started, I loaded VLC and asked it to 'open a disc'. It refused. I then asked it to 'open a folder' and pointed it to the Blu-Ray drive. It happily played the disc. I think when you ask VLC to play from a drive, it looks for a DVD as the error log said it could not find and Audio_TS or Video_TS directories/files.

5. You do not get the initial menu nor any advertisements. VLC starts playing the movie straight away. Next, Previous, Pause, Stop - all work.

I tried the following Blu-Rays successfully on VLC:

Ayan
Flight Of the Phoenix
Iron Man
King Kong
Dark Knight
The Rock
Om Shanthi Om
Rocket Singh
I-Robot
Zorro
Live Free Die Hard
Mission Impossible
Night At The Museum
Spiderman 3
Transporter 2

The only movie that I had as a standard sub-directory/file structure that VLC did not play was Magadheera. I have to see if I can get a log file and see what happens.

Please note that I have not installed any special codec packs. What I have installed are the following:

1. 10.12 version of ATI Catalyst
2. VLC
3. KMP Player
4. AnyDVD HD

My HTPC has an ATI 5770 card connected to my AVR through an HDMI cable.

I think VLC is well on it's way to be capable of playing Blu-Ray in all it's glory. If they introduce Menu capabilities, and native bit-stream of HD Audio, you may not need any other player. Tomorrow I will download and show the media information that VLC sees when it is playing a Blu-Ray.

.

I tried with avatar iso last night & vlc refused.I tried the main steam in ISO & it stopped a while & then started,but I cld see only dark screen.Audio in between with long pause.I guess vlc tried hard to play without any failure message,but cldnt do(may be lowerend card).You can try playing the BD file in stream folder in ISO.

3. In spite of whatever preferences you set, VLC sends audio as PCM which the receiver sees as Multi Channel.

Many times vlc dont save preferrence 1st time.I faced similar problem when vlc reads a multich file as stereo.After some time it automatically selects 5.1(PCM).SPDF not tried regularly so cant say if it saves OR not.

Have you selected "Use S/PDIF when available" under Preferences --> Audio.
If so, you shouldn't have to select 'A/52 over S/PDIF' every time. It should automatically do it as per the audio stream.

4. I inserted a copy of 2012 into the Blu-Ray drive. After shutting down PowerDVD that auto started, I loaded VLC and asked it to 'open a disc'. It refused.

Thats how VLC is supposed to behave as per the current build. There is no option to select BD (which has a different structure than DVD), in "Open Disc". So if you select DVD it will look for standard DVD structure.

5. You do not get the initial menu nor any advertisements. VLC starts playing the movie straight away. Next, Previous, Pause, Stop - all work.

That's either because you have selected "No DVD menus" or you have different values set for "Title" & "Chapter" under "Starting Position" in "Open Disc".

I have to check this out. In any case, I am a little lost with this as I am using HDMI only. I have also installed an 'AMD HDMI Audio' as the default device as part of Catalyst 10.12. Though VLC does show this device in preferences, it does not bit-stream through the device. It seems to do that only if you choose S/PDIF. Strange.

Again, I have to check this. I have not fooled around with anything excepting audio settings. If what you are saying is true, VLC should not show Menus in a DVD also. But it does.

Let me check. And thanks for the heads up.

How can you copy the BD folders into the HDD and play them? They have AACS encryption.
Are these pirated BDs?

Its not strange. That behavior is correct.
Actually "Use S/PDIF when available" has nothing to do exclusively with "S/PDIF" per se. This option is actually for passthrough. The word "S/PDIF" is misleading here. They should have written something like "Use SPDIF/HDMI when available".

Again, I have to check this. I have not fooled around with anything excpeting audio settings. If what you are saying is true, VLC should not show Menus in a DVD also. But it does.

Hmmm........that's interesting.

Aaaah, bad documentation and labelling? I should have though of that.

Thanks, OneTheRocks. Tonight I will test this out and also test out the Menu issue. If it works well, I can clean my HTPC of all the experimental media players, and just have VLC and PowerDVD. Though frankly I like the menuing and user interface of KM Player more. I will also see if KM Player plays Blu-Ray, though I doubt it very much.

Cheers

No my friend, they all are original. I have not yet seen or come across a pirated BD disc.

Read through the thread carefully and you will have your answer.

[reju]

Ok thanks. Let me also try this then

 

[venkatcr]

An update. I went into Preferences and set 'Use S/PDIF where available', and it worked.

Irrespective of what I did, VLC does not play Blu-Ray ISO. It does play DVD ISO easily with ads, menus, etc.

I could not find any options for ads and menus. As I said before, VLC does show ads and menus for DVD, but not for Blu-Ray.

Cheers

Thats good to know. Will check if VLC passes HD audio if connected to AVR. Chipset that I have does claim to be able to do that.

The 5770 is also supposed to pass HD Audio. I have not yet succeeded with either VLC nor with PowerDVD. I am planning to reinstall the OS on Monday, and take it step by step. If that does not work, I may have to overwrite the EDID of the AVR which is the last option. Tulli of AV Forum is an expert in that, and he has agreed to help.
