Open issues -----------1.How to handle an HDMI transmitter? It can be put in two different modes: DVI compatible or HDMI compatible. Some of the choices are a) enumerate them as two different outputs when enumerating. b) adding a status bit on the input. c) change it using a control 2. Detecting whether there is an analog or digital signal on an DVI-I input: a) add new status field value for v4l2_input ? #define V4L2_IN_ST_DVI_ANALOG_DETECTED 0x10000000 #define V4L2_IN_ST_DVI_DITIGITAL_DETECTED 0x20000000 3. Detecting an EDID. a) adding a status field in v4l2_output and two new ioctls that can set the EDID for an input or retrieve it for an output. It should also be added as an input/output capability. 4. ATSC bits in v4l2_std_id: how are they used? Are they used at all for that matter? 6. HDMI requires additional investigation. HDMI defines a whole bunch of infoframe fields. Most of these can probably be exported as controls?? Is HDMI audio handled by alsa?
7. how does this interface/co-exist with something like DSS2 on the omap3? who will "own" e.g. HDMI setup, DSS2 or V4L2? -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
