Ivtv driver options

Currently the only card featuring full decoding support is the Hauppauge PVR This driver requires the latest encoder firmware version 2.

Get the firmware from here:. The radio0 device may or may not be present, depending on whether the card has a radio tuner or not. For every extra card you have the numbers increased by one. If you have other capture cards e. WinTV PCI that are detected first, then you have to tell the ivtv module about it so that it will start counting at 1 or 2, or whatever. Otherwise the device numbers can get confusing. It is only available for cards that support video out. The raw audio PCM stereo stream from the currently selected tuner or audio line-in.

Reading from this device results in a raw signed 16 bit Little Endian, Hz, stereo pcm capture. This device only captures audio. This should be replaced by an ALSA device in the future. Note that there is no corresponding raw audio output device, this is not supported in the decoder firmware. The raw YUV video output from the current video input. Used to enable the radio tuner and tune to a frequency. You cannot read or write audio streams with this device.

Some people have a huge number of. If the bit is set, then the corresponding mailbox is in use by the driver. The first byte is a dummy byte that's never used.

However, it seems that the data must be 1K aligned, so we have to. This pointer array will allocate bytes to store each VBI frame. By reading back the. Rarely needed, only in some timing sensitive cases. Apparently if this is not done some motherboards seem. Ignore any errors. DVD and DVD Special 2 are DVD compliant mpeg2 streams which will give an mpeg2 stream which doesn't need to be replexed when it's in a compliant resolution and bitrate.

Note: with ivtv 0. This is an IVTV problem. Some motherboard chipsets apparently don't respond correctly to DMA resets. The search for a solution is ongoing. This problem appears to be fixed in 2. If you can't wait for 2.
