The VideoLAN Forums

Hi all,

I have an issue. I am trying to play blurays with VLC. I have a software (I don't know if I can name it in the forum), which decrypts blurays, so I have no issue with aacs or any encryption that can be on blurays. My issue is one step further : I play the bluray, and I have the feeling that VLC changes my screen resolution. Unfortunately, I am playing the bluray on my TV which is only HD Ready (no support of 1080p). The sound seems to work well, but not the picture since my TV claims "Signal non supporté" aka unsupported signal. I have tried to switch to OpenGL as rendering engine. It worked for some blurays like "The dark knight rises" or "How to train your dragon", but not for "James Cameron's Avatar".

Any idea ?

Thanks,
Nicolas

I need more info to even start guessing (or maybe I don't, I did a lot of guessing below!)...

How are you instructing VLC to play on the TV?

Can you see the Desktop on the TV before VLC is playing?

I believe you need to adjust the Video Card settings for the TV...you are using dual monitors, right? A computer monitor is primary & the TV is 2ndary?

I have never experienced VLC "changing my monitor's resolution"...but my computer is pretty old. VLC just "goes fullscreen" with the Desktop's resolution. Games DO change the resolution, but I've never had that with VLC.

So could you please explain, step-by-step, what you have done so far?...what your set-up is like?...specifically, HOW your TV is connected to the computer (HDMI?). Also, you mention Blu-Ray, does VLC play normally when it's not trying to do Blu-Ray?

It worked for some blurays like "The dark knight rises" or "How to train your dragon", but not for "James Cameron's Avatar".

...that really weird...so it does work?, but not for "some Blu-Rays"...the only thing I can say is perhaps the software which decrypts Blu-Rays isn't doing as good of a job as it thinks it is & is producing a corrupted rip?

OK try this...

1. Start VLC
2. Click Tools -> Messages
3. Set "Verbosity" to 1 or 2 (2 is more info, but possibly "too much info")
4. Play "The dark knight rises" for a few seconds.
5. Copy & Paste the log msgs to Notepad (or click "Save as..." & save it to a file).
6. Click "Clear"
7. Play "James Cameron's Avatar" for a few seconds.
8. Save that log too.
9. Post (or link to) both logs here

...then, perhaps repeat those steps, but this time playing on a normal computer monitor.

Perhaps, somehow, the HDCP signal got thru the decryption process & is forcing the HDCP-capable TV to reject it?

Perhaps this is an NTSC vs PAL issue? (but, again, I'd think the decryption process would eliminate that being a problem?)

Just a couple more things: What format is the decrypted Blu-Ray in? (ISO? or whatever a "Blu-Ray disc image" would be called) Can you play all Blu-Rays on a normal computer monitor? One thing you should be able to do (but perhaps not the best solution), would be to transcode the "Blu-Ray disc image" (if it's still in "disc image" format) into an mkv or other normal file format...assuming you can play all "normal files" on this TV.

Hi,

Thanks for your reply.

So here are my answers.

My computer is an HTPC, so I directly connected it to the TV through HDMI. No other display monitor.

I usually play my videos with VLC with no issue (either local files or DVD)

I have only PAL DVD & blurays, so no issue with NTSC.

I think you're right about HDCP. I am going to test verbosity, this weekend in the worse case, and post the logs back.
