ver 0.08 - added optional filtering of incoming line with 0..2 MHz LPF and 3+ MHz HPF - trigger button: I - interpolation control (1x or 8x) ... ver 0.07 - added K-factor borders from 1 to 10%, top is aligned to white level line and middle of the base to black level line, vertical pos - to time mark... - added 'press_and_drag' keyboard controls for some parameters (from graphical window): W - white level B - black level T - time mark X - horizontal shift S - horizontal scale trigger button: R - reset shift and scale ver 0.05 - added support for odd/even field detection and exact line number selection... stability of line viewing has no more depend on system's load... right mouse click still switch odd/even field lines - you may fast switch from 17 line of 1st field to 330 line of 2nd field. - converted to 1 single source project for both capture ICs. To build for BT8x8 IC based card define ICT_BT8X8 in Textures.h To build for SAA713X IC based card define ICT_SAA713X in Textures.h - finally fixed bug with crash on exit. - temporal interpolation for SNR is now 30 frames long. - added support for 'Enter/Return' button for Edit boxes, removed OK button - added call for Video Capture Filter properties before starting filtergraph - on my working MediaForte PV951 card it is required to set system format to PAL_B for the program to work correctly, or you will get an error and crash. - removed navigation on 22 and 335 lines because it cause crash on FlyVideo3000 card, possibly SAA713X driver do not provide enough data for these lines... if you want it - correct sources on your own risk, should works with BT8X8 cards though. - on startup 8x Sinc/Lanczos windowed interpolation is enabled now, disable it if it cause CPU or graphic card overload or if you want to see real signal samples from ADC of the capture card only.
