Hi: I have been playing with a MPEX encoder board, but I get lost in a world of problems.
First I patch + compile a new kernel (2.4.20) with v4l2 support. I install the 0.1.10 version of the saa7134 driver and I get the video0 and video1 devices, all ok. When I execute tscap with a video camera connected to the S-Video input, I get a nice black & white movie in a program stream (the absence of colour could be a connector issue, but I'm pretty sure that it works before...). Catting from /dev/video1 I get something that is almost a transport stream but with no tables. I suppose that I need to add them by hand, is that right? Neither mplayer nor vlan could play that stream without changes. When I want to use the v4l2 interface I get "invalid argument" from all ioctl calls that I tried. So, well, I install the newest version of the driver (0.2.9) from bytesex.org, with this driver I could get some info with the VIDIO_QUERYCAP and the VIDIO_ENUMINPUT ioctls: /dev/video0 capabilities ======================== Driver -> saa7134 Card -> EMPRESS Bus Info -> PCI:00:0c.0 Version -> 0.2.8 Supports video capture -> YES Supports video output -> NO Supports video overlay -> YES Supports VBI capture -> YES Supports VBI output -> NO Supports tuner -> YES Supports audio -> NO Supports read/write -> YES Supports async I/O -> NO Supports streaming -> YES /dev/video1 capabilities ======================== Driver -> saa7134 Card -> EMPRESS Bus Info -> PCI:00:0c.0 Version -> 0.2.8 Supports video capture -> YES Supports video output -> NO Supports video overlay -> NO Supports VBI capture -> NO Supports VBI output -> NO Supports tuner -> NO Supports audio -> NO Supports read/write -> YES Supports async I/O -> NO Supports streaming -> YES Video Inputs for /dev/video0 ============================ input 0 name -> Composite1 input 1 name -> S-Video input 2 name -> Television Video Inputs for /dev/video1 ============================ input 0 name -> CCIR656 A bit strange since I have no tuner and my board has 4 composite inputs ... But with this driver the video1 device returns an annoying string of zeros. So, how I could get some control over this encoder?. I need to be able to choose the video input at least, since AFAIK the TS output could not be tuned yet. Could someone can throw some light on any of my doubts? Thanks for your time in advance. -- --------------------- | Samuel | ---------------------
