Video de-blocking filter Help

Postby nataraajc » 16 Aug 2010 09:17

Hi,

We have come up with our own video de-blocking filter for VLC. We have no clue to integrate the same in the VLC player. Pls help us or throw some light on which module we can focus on to integrate our video de-blocking filter?

Thx
Natz

Do you have a separate module or is this included in another one?

Thanks for the quick response. I have it as separate module. I just want to integrate with VLC. What I exactly want to do is, I need to have the decoded buffer to do de-blocking. Then give that buffer for rendering.

Pls throw some lights on it.

Can you do that as a video filter or do you need to be at the decoding stage?

We are trying to make it work as Video Filter. But we are unclear about from where the video filter is getting called. And what are the modules we need to add/change to make it work. :(

Pls help. Thx.

Add a new video_filter like gradfun.c in modules/video_filters/ and compile it.
When done, activate it in the advanced preferences.

We are using the VLC v1.1.2, but I couldn't find the "gradfun.c in modules/video_filters/". Hope "mirror.c" also using the same filter concept. So after compiling the filter in the video_filters path, so the filter will automatically list in advanced preferences?

Where I can refer for find the flow of the filter below APIs?
1. Create
2. Destroy
3. Filter
4. FilterCallback

What is the use of "FilterCallback" API here?

Thx for the help. I am new to VLC development, pardon me for the basic queries. I tried enough to find, but couldn't :(

Can I go with mirror.c in VLC v1.1.2? Or gradfun.c is different implementation?
