Video Content Filtration - fingerprint

[hislitermos]

Hello,

I am running Videolan under Win7 ultimate. I have no problem with streaming or with generating sdp file.
I would like to know how I can filter instant private codes appearing on the screen when stream is started or when any code appearing in any given time.

Thanks in advance

Hello,

"coming up next" phrase which is not sliding or "sliding news" bar at the top/down are instant annotations.

I think below sample screenshots will give you an idea. Blurred region color of logo changes depending on background color of video content. If the background is yellow at that moment, logo color changes to yellow but the video quality becomes blurred inside logo borders.

Those sample screenshots are what i would like to succeed:

What i did :

- created a green rectangular logo.png file in paintbrush
- in vlc tools->effects & filters-> video effects tab -> overlay -> ticked logo -> select the logo.png file -> set the position by changing px parameters

Here is my current status:

How does vlc automatically detect background color and changes logo.png's color in two dimensions (x;y) ?

Thanks in advance

Did you try the unlogo filter?

Thanks.
I think what you mean is shown in this video:

What I need to do is a little bit different. When the background color of video changes, color of logo will be changed automatically. Is this possible with VLC?


Thanks in advance

"erase" video filter.

- in vlc tools->effects & filters-> video effects tab -> overlay -> ticked logo -> select the logo.png file -> set the position by changing px parameters

Tick "[v] Logo erase" that is next to "[ ] Logo" right there.

Thank you so much!
That is perfect when I am playing a video.
When I start the stream, it is not appearing. To do this, I tried below code :

Code: Select all

sfilter={marq{marquee=x=300,y=80}:logo{file=C:\Users\pc\Desktop\logo.png}}

What should I put instead of marquee or marq in above line ?


Thanks in advance

Erase video filter
Remove zones of the video using a picture as mask
--erase-mask=<string> Image mask
Image mask. Pixels with an alpha value greater than 50% will be
erased.
--erase-x=<integer [-2147483648 .. 2147483647]>
X coordinate
X coordinate of the mask.
--erase-y=<integer [-2147483648 .. 2147483647]>
Y coordinate
Y coordinate of the mask.

Put

Code: Select all

vfilter=erase{mask="d:\pictures\mask.png",x=10,y=50}

or just

Code: Select all

vfilter=erase

in your transcoding chain in generated stream output string in the GUI (Media > Stream...).
