Name CX2341X_ENC_UNKNOWN
Name CX2341X_ENC_SET_VERT_CROP_LINE
Enum 219/0xDB
Description
Unknown API, it's used by Hauppauge though.
Something to do with 'Vertical Crop Line'
Param[0]
0 This is the value Hauppauge uses, Unknown what it means.
If saa7114 and raw VBI capture and 60 Hz, then set to 10001.
Else 0.

Command number:
1=set initial SCR value when starting encoding (works).
2=set quality mode (apparently some test setting).
3=setup advanced VIM protection handling (supposedly only for the cx23416
for raw YUV).
Actually it looks like this should be 0 for saa7114/5 based card and 1
for cx25840 based cards.
4=generate artificial PTS timestamps
3=setup advanced VIM protection handling.
Always 1 for the cx23416 and 0 for cx23415.
4=generate DVD compatible PTS timestamps
5=USB flush mode
6=something to do with the quantization matrix
7=set navigation pack insertion for DVD: adds 0xbf (private stream 2)

9=set history parameters of the video input module
10=set input field order of VIM
11=set quantization matrix
12=reset audio interface
12=reset audio interface after channel change or input switch (has no argument).
Needed for the cx2584x, not needed for the mspx4xx, but it doesn't seem to
do any harm calling it regardless.
13=set audio volume delay
14=set audio delay
