Hi everybody. Working to round off NVrec, I have run into 2 problems, and I was hoping someone on the list might be able to lend a hand. My appologies for posting slightly off-topic :-(. 1) Is there any way to get the frame rate / frame period from a V4L1 device? I don't see anything that returns it specifically. I do see that GCHAN gives back a norm, although the API doesn't define what the values returned in norm will be... 2) How do I get my files longer than 4GB? For some reason I cannot seem to get it right, even with programs that claim to support long file names! As far as I can see, compiling with -D_FILE_OFFSET_BITS=64 should do the trick, and it does seem to work, if you "nm" the result, you can see it uses open64, rather than open, but all the read/write functions remain the same! Any tips/help would be greatly appreciated! Thanks, Justin
