You may need to select an antenna. I don't have one so I can't really help - I do believe it works though.
Any progress?
It sounds like the soapysdr output needs to be in its own thread. I had naively thought it wouldn't need to be.
Some more information on these test signals: http://zone.ni.com/reference/en-XX/help/373389B-01/nivms/pal_patterns/ https://www.itu.int/rec/T-REC-J.61-199006-I/en They occupy lines 17, 18, 330 and 331 on PAL systems (and I presume SECAM as well). I will add these...
My first go at a VITS generator is now committed. Use `--vits` to enable. The phase of the chrominance signals are going to be wrong, and it's not supported on...
YUYV and MJPG are supported formats so in theory this should work. On some cameras not all colour pixel formats are available at all resolutions. It might be worth trying...
The bottleneck I kept hitting on my older machine was memory bandwidth, rather than processing power. I'm not sure multiple threads would help in that case, but it certainly wouldn't...
I don't think NICAM is any more intensive than FM audio, but it's often just enough to push slower machines over the edge. I believe the main issue for performance...
Does this happen in other applications or just fswebcam?
Not at the moment. It should be relatively simple to add though, but there may be issues with A/V sync.
