Hi Steve, I just got around to trying the new card. My hardware: generic 400MHz PII SIIG 1394 interface model # NN2603. Canon Elura camcorder (NTSC) I'm using the following software: linux kernel -- vanilla 2.2.14 (on RH 6.1 dist) ieee1394 -- I started with the patch, then I replaced the driver with the current CVS version libraw -- current CVS version dvgrab -- 0.7 + Alastair Mayer's patch to generate raw output for libdv libdv -- CVS version I have strange results. The first two tries produced video with odd sync problems, i.e. the picture from playdv (libdv) was vertically offset by about 2/3 of a frame. A third one produced video that seemed OK, but playdv seg faulted (I think on the last frame). The commands I use : dvgrab --ntsc --frames 300 --dv file playdv file.dv At one point, I unloaded/reloaded the ohci module. Since then, I've done about 8 clips in a row that all work correctly. Takes time to warm up? 8-| -- Buck ps Here is what I see in my syslog: Apr 24 23:55:44 c360746-a kernel: ieee1394: registered ohci1394 driver, initializing now Apr 24 23:55:44 c360746-a kernel: ohci1394: looking for Ohci1394 cards Apr 24 23:55:44 c360746-a kernel: ohci1394_0: allocated interrupt 15 Apr 24 23:55:44 c360746-a kernel: ohci1394_0: remapped memory spaces reg 0xc8854000 Apr 24 23:55:44 c360746-a kernel: ohci1394_0: soft reset finished Apr 24 23:55:44 c360746-a kernel: ohci1394_0: max packet size = 2048 bytes Apr 24 23:55:44 c360746-a kernel: ohci1394_0: 4 iso contexts available Apr 24 23:55:44 c360746-a kernel: ohci1394_0: Receive DMA ctx=0 initialized Apr 24 23:55:44 c360746-a kernel: ohci1394_0: Receive DMA ctx=1 initialized Apr 24 23:55:44 c360746-a kernel: ohci1394_0: AT dma ctx=0 initialized Apr 24 23:55:44 c360746-a kernel: ohci1394_0: AT dma ctx=1 initialized Apr 24 23:55:44 c360746-a kernel: ohci1394_0: Receive DMA ctx=2 initialized Apr 24 23:55:44 c360746-a kernel: ohci1394_0: resetting bus on request and attempting to become root Apr 24 23:55:44 c360746-a kernel: ieee1394: detected 1 ohci1394 adapter Apr 24 23:55:44 c360746-a kernel: ohci1394_0: SelfID process finished (phyid 1, root) Apr 24 23:55:44 c360746-a kernel: ohci1394_0: selfid packet 0x807f0880 rcvd Apr 24 23:55:44 c360746-a kernel: ohci1394_0: selfid packet 0x817f815e rcvd Apr 24 23:55:44 c360746-a kernel: ohci1394_0: This node self-id is 0x817f815e Apr 24 23:55:44 c360746-a kernel: ohci1394_0: calling self-id complete Apr 24 23:55:44 c360746-a kernel: ohci1394_0: Got phy packet ctx=0 ... discarded Apr 24 23:56:48 c360746-a kernel: ohci1394_0: listening enabled on channel 63 Apr 24 23:56:58 c360746-a kernel: ohci1394_0: listening disabled on iso channel 63 |
