2008-01-25V4L/DVB (6698): pvrusb2: Implement signal routing schemesMike Isely
The exact routing of video and audio signals within a device is a device-specific attribute. Hauppauge devices do it one way; other types of device may route things differently. Unfortunately it is rather impractical to define chip-specific routing at the device attribute level, so instead what happens here is that "schemes" are defined. Each chip level interface implements its part of a given scheme and the scheme as a whole is made into a device specific attribute controlled via a table entry in pvrusb2-devattr.c. The only scheme defined here is for Hauppauge devices, but clearly this opens the door for other possibilities to follow.

2008-01-25V4L/DVB (6691): pvrusb2: Rework pipeline state controlMike Isely
This is a new implementation for video pipeline control within the pvrusb2 driver. Actual start/stop of the pipeline is moved to the driver's kernel thread. Pipeline stages are controlled autonomously based on surrounding pipeline or application control state. Kernel thread management is also cleaned up and moved into the internal control structure of the driver, solving a set up / tear down race along the way. Better failure recovery is implemented with this new control strategy. Also with this change comes better control of the cx23416 encoder, building on additional information learned about the peculiarities of controlling this part (this information was the original trigger for this rework). With this change, overall encoder stability should be considerably improved. Yes, this is a large change for this driver, but due to the nature of the feature being worked on, the changes are fairly pervasive and would be difficult to break into smaller pieces with any semblence of step-wise stability.

2006-06-27V4L/DVB (4228a): pvrusb2 to kernel 2.6.18Mike Isely
Implement V4L2 driver for the Hauppauge PVR USB2 TV tuner. The Hauppauge PVR USB2 is a USB connected TV tuner with an embedded cx23416 hardware MPEG2 encoder. There are two major variants of this device; this driver handles both. Any V4L2 application which understands MPEG2 video stream data should be able to work with this device.
