3. rebuild and install VLC 2.0.1 Twoflower (2.0.1-0-gf432547) with support decklink sdi.

All capture and streaming - OK!
but the filter doesn't work 'deinterlace',
.......
main filter debug: no video filter2 module matching "deinterlace" could be loaded
main filter debug: TIMER module_need() : 0.256 ms - Total 0.256 ms / 1 intvls (Avg 0.256 ms)
main stream out error: Failed to create video filter2 'deinterlace'
........


if to streaming the video file everything it is normal, the filter 'deinterlace' work -OK!
..................
main filter debug: looking for video filter2 module: 1 candidate

I think this is normal. The deinterlace module does not deinterlace all formats.

Sorry for taking your thread. Could you mayby help a noob out here. I also want to use vlc with decklink but havent found any information telling me how. Could you mayby get me in the right direction ?

Exactly how do you compile vlc to get the decklink support ?

I would be so happy if you could help me out with this.

You need recompile vlc against the Decklink SDK.

You'll need to alter the configure line to enable decklink support and point it to the libs from the SDK. Depending on your environment, you may also have to have to add this include to your "CFLAGS"

Code: Select all

CFLAGS=" -I/usr/include/decklink $SLKCFLAGS" --enable-decklink --with-decklink-sdk=/usr/include/decklink
