Hi I also posted this on the general list....
Further to my last message I did not specify that the card is an Adaptec Videoh! Media Center, part number AVC-2410. I have captured the audio from /dev/video24 and imported it into Audacity as signed 16 bit Little endian 48000Hz stereo PCM. Then I noticed that it appeared to be twice as long as it should be. I then changed the clip to double speed and it played OK, if I imported it at 96000Hz it also plays OK. I therefore assume that the audio is being mixed into the MPEG at half speed, causing it to sound distorted. Is there a setting I can alter to correct this. I have an AVC-2410 video capture card which works fine in Windows. I am trying to get it working under Linux using the ivtv driver. The board has the following components on: SAA7115HL Micronas MSP3415G Philips FZ1216M3/I H-3 53L32AKZ PIC16C54C 48LCM32B2 Plus another large chip with a sticker labelled "AVC-2410/EU PAL VIDEO CONVTR 2053600EU A 0440 M" covering its number I have installed ivtv-0.2.0-rc3d using the instructions on the website: http://www.byopvr.com/Journal+index-jop-browse-mode-view-id-112.html The only real problem I had was extracting the firmware from the file avcpwilo.sys but I got around that by editing ivtvfwextract.pl to set $fw_driver_name = "avcpwilo.sys" and $tmpdir to /home/mythtv/tmp and then I copied avcpwilo.sys to /home/mythtv/tmp and copied a gzipped version of avcpwilo.sys to /home/mythtv and from /home/mythtv I ran ivtvfwextract2.pl avcwilo.sys.gz ./enc.img ./dec.img. I then copied enc.img to /lib/modules/ivtv-fw-enc.bin and dec.img to /lib/modules/ivtv-fw-dec.bin I then loaded the modules: modprobe i2c-core modprobe i2c-algo-bit bit_test=1 modprobe tuner type=24 modprobe msp3400 simpler=1 standard=0x0a debug=1 modprobe videodev modprobe saa7115 modprobe tveeprom modprobe ivtv and changed some settings: ivtvctl -p3 # set to composite input ivtvctl -ybrightness=200 # set brightness ivtvctl -u 0xff # set to PAL at this point if I run mplayer /dev/video0 -vc ffmpeg12 I get good video, but the sound is distorted with a lot of bass in it and speech is almost impossible to understand.
