[Discuss-gnuradio] DVB-T

[Vincenzo Pellegrini]

you can open the .VRO with mplayer it's just mpeg2 as it comes out of a sony dvd camera :-)

I will release the patched ffmpeg, however the modification is indeed very simple, I just added multi channel TS support, to the already existing TS container functionality.
any good programmer can do a much better job than I did on this.. ;)

Ciao Vince,
Great to listen this good news!

Some questions:
What kind of file is this (.VRO)?
Where can I find the ffmpeg patches?
