my card number is 183 , but I do not know how to change it

already try to remove and add the module with

rmmod saa7134_alsa saa7134_dvb saa7134
modprobe saa7134 card=183

modprobe saa7134-dvb

/$ ls dev/d* result

dev/dm-0 dev/dm-1

dev/disk:

by-id by-uuid

obviously tvheadend does not show adapters

I hope you have explained me well, tanks

mpmc

See modprobe saa7134 for module options.


echo "options saa7134 card=183" | sudo tee /etc/modprobe.d/dvb.conf
reboot

However that card +isn't a DVB card+ so won't work with newer tvheadend versions. The last version to support analogue (3.6) is no longer supported.

thanks for answering

I reinstall ubuntu and apply what you suggested , do not compile the linuxtv firmware

it's correct like this?

Could my card work with a version 3.6 or earlier?

Do non-analog cards ,dvb-t, work with an RGB cable entry? , that is, I receive analog RGB signal

There is a nice commandlsdvb

Lot of people make mistake to count "silicon" analog tuners as digital one.

laura ferreri

I apologize for my ignorance on the subject

if I already understood that my adapter is not dvb

I reiterate the questions

You mean as capture device
not it cannot do that also directly
if stream from ffmpeg then it can
else use zoneminder

Hi !

I'm still with this issue, try to use Mythtv but I'm not convinced

So, I can compile version 3.4

Output is the following:

[WARNING]:v4l: /dev/video0: Device lacks MPEG encoder, device skipped

I understand that tvheanded needs mpeg to work, according to the manufacturer the card supports mpeg2

but dmesg | grep saa7134 , does not register any adapter as mpeg

it's a problem with the v4l2 driver or my card does not really support mpeg at the hardware level ?
