Hi Doug, Firstly, let me say; wow! Thanks so much for all your great info!!! If that was you being vague I want to be around when you get specific! I finally got some time to try your directions out this evening (damn Citrix for scheduling iForum this week!) and can you believe it, I have the tuner being recognised!!! Oh yeah! I haven't gotten to plugging in the antenna and actually trying to tune something in - but I'm happy to be at the point where the blue light comes on! Thanks heaps, BKCH. -----Original Message----- From: Doug Scoular [mailto:dscoular@xxxxxxxxx] Sent: Monday, 18 July 2005 11:20 AM To: bhackney@xxxxxxxxxxxxxx Cc: linux-dvb@xxxxxxxxxxx Subject: Re: [linux-dvb] re: AverMedia AVerTV DVB-T USB 2.0 driver Hi BKCH, I've successfully installed my AverMedia AverTV DVB-T USB 2.0 (aka a800) device and it works pretty wonderfully under gentoo and a generic 2.6.12.1. It has issues with MythTV though... sigh. It is a daunting process to get it all working if you are new to linux (even if you are not new ;^) In this email I've tried to outline how I got it working... but it is from memory and on a gentoo box rather than a Fedora Core 4 box. Patrick's answer: > Have a look into your /etc/hotplug/firmware.agent for FIRMWARE_DIRS. Should get you started. On gentoo my firmware.agent defines FIRMWARE_DIR and it is set to: spug root # grep FIRMWARE /etc/hotplug/firmware.agent # FIRMWARE=%s FIRMWARE_DIR=/lib/firmware Which appears to be the same on Fedora Core 3 too, not sure about Fedora Core 4... I'd assume it would be the same. Copy your dvb-usb-avertv-a800-02.fw file there. I suspect, however, that you are actually missing the a800 driver and supporting modules. The a800 module which drives your AverTV box only exists in dvb-kernel CVS or the very latest kernel patch (AFAIK). It is part of the dvb driver infrastructure required to detect the box, initialise it with the appropriate firmware and then start controlling it. There's quite a bit more to getting the AverTV box working than simply copying the firmware to the appropriate FIRMWARE_DIR. You'll also need to compile and install the latest dvb-kernel, either from 1) CVS or 2) compile a generic kernel from source and apply the appropriate patch for that kernel. Both options are fairly complicated at the moment for several reasons: 1) The latest CVS version seems to require 2.6.13.x to compile (I could be wrong). 2) Applying the patch requires you compiling your kernel from source. I'd suggest option 2) is the easier. I'm not sure whether the patch will apply cleanly to the source for your 2.6.12-1.1390_FC4smp. What I would do is download the generic 2.6.12 kernel from kernel.org. Unpack it into /usr/src/linux-2.6.12 and copy your 2.6.12-1.1390_FC4smp kernel config from /boot/config-2.6.12-1.1390_FC4smp to that directory as your new ".config" file e.g. cd /usr/src wget http://kernel.org/pub/linux/kernel/v2.6/linux-2.6.12.tar.bz2 tar jxvf /tmp/linux-2.6.12.tar.bz2 cd linux-2.6.12 cp /boot/config-2.6.12-1.1390_FC4smp .config You now need to grab the matching 2.6.12 dvb-kernel patch: wget http://linuxtv.org/downloads/patches/2.6.12/DVB-2.6.12.patch.gz and apply it to your generic kernel source: gzcat ../DVB-2.6.12.patch.gz | patch -p1 Then I would use all the answers currently found in your Fedora .config file to answer the majority of the 2.6.12 configuration questions by running: make oldconfig This will no doubt throw up some complaints about backported Fedora features and patches but you should be able to ignore these, but what you must not ignore are the questions about new modules. I'd simply answer "m" to all DVB/USB related modules. When that's finished you will have a new .config file ready to be used by the compilation process. Now you need to compile your kernel: make make modules_install You then need to install your new kernel, create a new initial RAM disk (initrd) and set up grub to boot that new kernel. Lets put the kernel in the right place and then create an initial RAM disk: cp arch/i386/boot/bzImage /boot/vmlinuz-2.6.12 mkinitrd /boot/initrd-2.6.12.img 2.6.12 You will then need to edit your grub configuration and add a new stanza for your new experimental kernel: vi /boot/grub/grub.conf So, if you have a stanza like: title Fedora Core (2.6.9-1.667) root (hd0,1) kernel /vmlinuz-2.6.9-1.667 ro root=/dev/VolGroup00/LogVol00 rhgb quiet initrd /initrd-2.6.9-1.667.img Add another one after this that look similar but has a different title and refers to your new experimental kernel: title DVB Kernel 2.6.12 root (hd0,1) kernel /vmlinuz-2.6.12 ro root=/dev/VolGroup00/LogVol00 rhgb quiet initrd /initrd-2.6.12.img Note that your root device and root kernel parameters may well be different from mine! Use yours!!! Now you should be able to reboot and at the grub prompt you will have a couple of seconds where you can select your new experimental DVB Kernel 2.6.12 entry. Note that you can try patching later kernels such as 2.6.12.3 if you want even more stability... it's just that I don't know if the patch applies cleanly to kernels other than generic 2.6.12... hey it may even apply agains the FC4 kernel source. If this boots okay, login as root and try running the following commands (note that some of these may be unrelated to your AverTV box... I just load them all: modprobe dvb-usb modprobe dvb-usb-vp7045 modprobe dvb-usb-dtt200u modprobe dvb-usb-dibusb-common modprobe dvb-usb-dibusb-mb modprobe dvb-usb-dibusb-mc modprobe dvb-usb-a800 modprobe dvb-usb-nova-t-usb2 modprobe dvb-usb-umt-010 modprobe dvb-usb-digitv modprobe dvb-usb-cxusb Now if you look in /var/log/messages or run the dmesg command you should see your AverTV box load up and initialise with the firmware it finds. If all went well you should see new devices in /dev/dvb/adapter? Where ? will be 0 for your first dvb device. Next you need some way of tuning your card and capturing streams... this is where I get even vaguer. I'm assuming you can just use the released dvd-apps against this kernel patch... but I could be wrong... you may need to get the dvb-apps from CVS to work but let's assume the last released linuxtv-dvb-apps will work. Grab the source and unpack them: cd /usr/src wget http://linuxtv.org/downloads/linuxtv-dvb-apps-1.1.0.tar.bz2 tar jxvf linuxtv-dvb-apps-1.1.0.tar.bz2 Then follow the instructions to compile the utilities. Should be a simple: cd linuxtv-dvb-apps-1.1.0 make But my memory fails me... After that you can then try and scan your DVB transmitter for channels: cd utils/scan ./scan dvb-t/au-sydney_north_shore And you should see something like: scanning dvb-t/au-sydney_north_shore using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0' initial transponder 226500000 1 3 0 3 1 1 0 initial transponder 177500000 1 2 0 3 1 2 0 initial transponder 191625000 1 3 0 3 1 1 0 initial transponder 219500000 1 3 0 3 1 1 0 initial transponder 571500000 1 2 0 3 1 2 0 >>> tune to: 226500000:INVERSION_AUTO:BANDWIDTH_7_MHZ:FEC_3_4:FEC_NONE:QAM_64:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_16:HIERARCHY_NONE 0x0000 0x0223: pmt_pid 0x0000 ABC -- ABC TV (running) 0x0000 0x0220: pmt_pid 0x0000 ABC -- ABC HDTV (running) 0x0000 0x0222: pmt_pid 0x0000 ABC -- ABC2 (running) 0x0000 0x0221: pmt_pid 0x0000 ABC -- ABC TV Sydney (running) 0x0000 0x0227: pmt_pid 0x0000 ABC -- ABC DiG Jazz (running) 0x0000 0x0226: pmt_pid 0x0000 ABC -- ABC DiG Radio (running) Network Name 'ABC Sydney' >>> tune to: 177500000:INVERSION_AUTO:BANDWIDTH_7_MHZ:FEC_2_3:FEC_NONE:QAM_64:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_8:HIERARCHY_NONE 0x0000 0x0520: pmt_pid 0x0200 Seven Network -- 7 Digital (running) 0x0000 0x0524: pmt_pid 0x0240 Seven Network -- 7 HD Digital (running) 0x0000 0x0521: pmt_pid 0x0210 Seven Network -- 7 Digital 1 (running) 0x0000 0x0522: pmt_pid 0x0220 Seven Network -- 7 Digital 2 (running) 0x0000 0x0523: pmt_pid 0x0230 Seven Network -- 7 Digital 3 (running) 0x0000 0x0526: pmt_pid 0x0260 Seven Network -- 7 Guide (running) Network Name 'Seven Network' >>> tune to: 191625000:INVERSION_AUTO:BANDWIDTH_7_MHZ:FEC_3_4:FEC_NONE:QAM_64:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_16:HIERARCHY_NONE 0x0000 0x0001: pmt_pid 0x0000 Nine Network -- NINE DIGITAL (running) 0x0000 0x0002: pmt_pid 0x0000 Nine Network -- NINE MULTIVIEW 1 (running) 0x0000 0x0005: pmt_pid 0x0000 Nine Network -- NINE HD (running) 0x0000 0x0006: pmt_pid 0x0000 Nine Network -- NINE GUIDE (running) Network Name 'Nine Network Austrlia' >>> tune to: 219500000:INVERSION_AUTO:BANDWIDTH_7_MHZ:FEC_3_4:FEC_NONE:QAM_64:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_16:HIERARCHY_NONE Network Name 'Network TEN' 0x0000 0x0623: pmt_pid 0x0103 Ten Sydney -- TEN Digital 2 (running) 0x0000 0x0625: pmt_pid 0x0100 Ten Sydney -- TEN Digital (running) 0x0000 0x0621: pmt_pid 0x0101 Ten Sydney -- TEN Digital (running) 0x0000 0x0622: pmt_pid 0x0102 Ten Sydney -- TEN Digital 1 (running) 0x0000 0x0624: pmt_pid 0x0104 Ten Sydney -- TEN Digital 3 (running) 0x0000 0x0627: pmt_pid 0x0106 Ten Sydney -- TEN Guide (running) 0x0000 0x0628: pmt_pid 0x0107 Ten Sydney -- TEN HD (running) 0x0000 0x0629: pmt_pid 0x0108 Ten Sydney -- TEN Guide (running) >>> tune to: 571500000:INVERSION_AUTO:BANDWIDTH_7_MHZ:FEC_2_3:FEC_NONE:QAM_64:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_8:HIERARCHY_NONE 0x0000 0x0300: pmt_pid 0x0400 SBS -- SBS HD (running) 0x0000 0x0301: pmt_pid 0x0401 SBS -- SBS DIGITAL 1 (running) 0x0000 0x0302: pmt_pid 0x0402 SBS -- SBS DIGITAL 2 (running) 0x0000 0x0304: pmt_pid 0x0408 SBS -- SBS EPG (running) 0x0000 0x030e: pmt_pid 0x0403 SBS -- SBS RADIO 1 (running) 0x0000 0x030f: pmt_pid 0x0404 SBS -- SBS RADIO 2 (running) Redirect the output of this to a file: ./scan dvb-t/au-sydney_north_shore > aver-channels.conf Now you can try tuning to the channels found in aver-channels.conf: ../szap/tzap -c aver-channels.conf 'TEN DIGITAL' And you should see: using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0' tuning to 219500000 Hz video pid 0x0200, audio pid 0x028a status 03 | signal 8020 | snr 0040 | ber 001fffff | unc 0000ffff | status 1f | signal 8021 | snr 003f | ber 00000000 | unc 00000000 | FE_HAS_LOCK If you see "FE_HAS_LOCK" it means you have successfully tuned to that channel!!! Woo hoo!!! Next you can try asking tzap to read the data stream from your AverTV box as a background process: ../szap/tzap -c aver-channels.conf 'TEN DIGITAL' -r > /dev/null 2>&1 & Now you can capture MPEG2 video: cat /dev/dvb/adapter0/dvr0 > bigfile.mpg Wait a couple of minutes and then ^C out of the "cat" command. Kill the tzap background job via: kill -9 %% Then try watching the video you recorded with mplayer or xine.
