| #define IOCTL_ETHJPG2K_ADV212_READ_REG IOCTL_ETHJPG2K(0x91) |
Reads a register from the ADV212. The argument is a pointer to an array of 2 ints: first is the register number, second is the value.
Definition at line 78 of file ethjpg2k.h.
| #define IOCTL_ETHJPG2K_ADV212_WRITE_REG IOCTL_ETHJPG2K(0x90) |
Writes a register of the ADV212. The argument is a pointer to an array of 2 ints: first is the register number, second is the value.
Definition at line 75 of file ethjpg2k.h.
| #define IOCTL_ETHJPG2K_ENC_QUALITY IOCTL_ETHJPG2K(0x58) |
Dynamically (so only when the encoder is running) sets the quality of the output stream. Parameter is an int which is the RCVAL.
Definition at line 22 of file ethjpg2k.h.
| #define IOCTL_ETHJPG2K_ENCDEC_LOAD_FIRMWARE IOCTL_ETHJPG2K(0x51) |
The firmware is transferred to the driver via a struct ETHJPG2K_FIRMWARE_DATA.
Definition at line 15 of file ethjpg2k.h.
| #define IOCTL_ETHJPG2K_ENCDEC_START IOCTL_ETHJPG2K(0x52) |
The encoder/decoder is started.
Definition at line 17 of file ethjpg2k.h.
| #define IOCTL_ETHJPG2K_ENCDEC_STOP IOCTL_ETHJPG2K(0x53) |
The encoder/decoder is stopped.
Definition at line 19 of file ethjpg2k.h.
| #define IOCTL_ETHJPG2K_GPIO_READ IOCTL_ETHJPG2K(0x60) |
Reads the current output GPIO value. The argument is a pointer to an int. This IOCTL is used for masking only the bits that the user needs to change.
Definition at line 29 of file ethjpg2k.h.
| #define IOCTL_ETHJPG2K_GPIO_WRITE IOCTL_ETHJPG2K(0x61) |
Writes to he output GPIO pins implemented on the CTR1474. The argument is a pointer to an int.Only the pins 0-7 are user available. Bits 8 and 9 control the 2 LEDs on the board. Bit 9 switches the data path between the video front-end and the ADV212 between encoding and decoding modes.
Definition at line 35 of file ethjpg2k.h.
| #define IOCTL_ETHJPG2K_GPIO_WRITE_READ IOCTL_ETHJPG2K(0x62) |
Reads the current output GPIO value. The argument is a pointer to an int. This IOCTL is used for masking only the bits that the user needs to change.
Definition at line 39 of file ethjpg2k.h.
| #define IOCTL_ETHJPG2K_LINUX_GETBSIZE IOCTL_ETHJPG2K(0x71) |
The size (in pages) of the buffer for the acquisition of images is returned.
Definition at line 47 of file ethjpg2k.h.
| #define IOCTL_ETHJPG2K_LINUX_INIT IOCTL_ETHJPG2K(0x70) |
This IOCTL initializes the companion chips on the CTR1474. Should be called before any attempt to encode/decode a video stream.
Definition at line 45 of file ethjpg2k.h.
| #define IOCTL_ETHJPG2K_LINUX_SETBUF IOCTL_ETHJPG2K(0x72) |
Sets the dimensions of the image ring buffer. Pass a ethjpg2k_linux_imgbuf structure.
Definition at line 50 of file ethjpg2k.h.
| #define IOCTL_ETHJPG2K_TW2835_BATCH IOCTL_ETHJPG2K(0x84) |
Does a batch of operations to reduce the number of context switches (it'useful when downloading bitmaps for example). The argument is a pointer to an an array of ints. The first one is the length of remaining elements. After it the actual operations.
Definition at line 69 of file ethjpg2k.h.
| #define IOCTL_ETHJPG2K_TW2835_READ_REG IOCTL_ETHJPG2K(0x81) |
Reads a register from the TWA2835. The argument is a pointer to an array of 2 ints: first is the register number, second is the value.
Definition at line 59 of file ethjpg2k.h.
| #define IOCTL_ETHJPG2K_TW2835_RESET IOCTL_ETHJPG2K(0x82) |
Resets the TWA2835.
Definition at line 61 of file ethjpg2k.h.
| #define IOCTL_ETHJPG2K_TW2835_TOUT_SEC IOCTL_ETHJPG2K(0x83) |
Sets the timeout (in seconds) when waiting for an event from the video front-end.
Definition at line 64 of file ethjpg2k.h.
| #define IOCTL_ETHJPG2K_TW2835_WRITE_REG IOCTL_ETHJPG2K(0x80) |
Writes a register of the TWA2835. The argument is a pointer to an array of 2 ints: first is the register number, second is the value.
