Name CX2341X_ENC_SET_VBI_LINE
Enum 183/0xB7
Description
Param[1]
Unknown, but leaving this to 0 seems to work best. Indications are that
this might have to do with USB support, although passing anything but 0
- onl breaks things.
+ only breaks things.

'01'=JointStereo
'10'=Dual
'11'=Mono
- Note: testing seems to indicate that Mono and possibly
- JointStereo are not working (default to stereo).
- Dual does work, though.
+ Note: the cx23415 cannot decode Joint Stereo properly.
10:11 Mode Extension used in joint_stereo mode.
In Layer I and II they indicate which subbands are in
Enum 199/0xC7
Description
Sets the Program Index Information.
+ The information is stored as follows:
+
+ struct info {
+ u32 length; // Length of this frame
+ u32 offset_low; // Offset in the file of the
+ u32 offset_high; // start of this frame
+ u32 mask1; // Bits 0-1 are the type mask:
+ // 1=I, 2=P, 4=B
+ u32 pts; // The PTS of the frame
+ u32 mask2; // Bit 0 is bit 32 of the pts.
+ };
+ u32 table_ptr;
+ struct info index[400];
+
+ The table_ptr is the encoder memory address in the table were
+ *new* entries will be written. Note that this is a ringbuffer,
+ so the table_ptr will wraparound.
Param[0]
Picture Mask:
0=No index capture
1=I frames
3=I,P frames
7=I,P,B frames
+ (Seems to be ignored, it always indexes I, P and B frames)
Param[1]
Elements requested (up to 400)
Result[0]
- Offset in SDF memory of the table.
+ Offset in the encoder memory of the start of the table.
Result[1]
Number of allocated elements up to a maximum of Param[1]
Enum 203/0xCB
Description
Returns information on the previous DMA transfer in conjunction with
- bit 27 of the interrupt mask. Uses mailbox 9.
+ bit 27 or 18 of the interrupt mask. Uses mailbox 9.
Result[0]
Status bits:
- Bit 0 set indicates transfer complete
- Bit 2 set indicates transfer error
- Bit 4 set indicates linked list error
+ 0 read completed
+ 1 write completed
+ 2 DMA read error
+ 3 DMA write error
+ 4 Scatter-Gather array error
Result[1]
DMA type

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.

the value.
Param[0]
Command number:
- 1=set initial SCR value when starting encoding.
+ 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
+ 7=set navigation pack insertion for DVD: adds 0xbf (private stream 2)
+ packets to the MPEG. The size of these packets is 2048 bytes (including
+ the header of 6 bytes: 0x000001bf + length). The payload is zeroed and
+ it is up to the application to fill them in. These packets are apparently
+ inserted every four frames.
8=enable scene change detection (seems to be a failure)
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
