The stk1160 driver in the kernel (3.7 and upward) supports:
- video capturing
- PAL at 25 fps at 720x576
- NTFS at 30 fps at 720x480
- S-Video from input Nr. 4
- the CVBS + S-Video model and
- the four CVBS model (all four channels)
- audio capturing
- must be enabled in the mixer settings (read more on this post)
- audio capturing only from the CVBS + S-Video model with built in AC'97 chip (3 chip Easycap; 48000Hz model) is supported
- The Easycap works even if it is connected to an USB 2.0 hub.
- Use a powered hub if you get a crampy picture.
Some performance issues are caused by too low power provided by some small boards (like Raspberry PI). - Some USB 3.0 hosts may have bandwith limitation, then it can cause problems with stk1160.
Supported features
- Two (or more) stk1160 devices working side by side on one system
(If this is not possible, it's not a driver issue, but rather about USB bandwidth) - Switching channels/ inputs while capturing (with the v4l2-ctl tool - read more on this post.).
- Famescaling
Only full PAL or NTFS frames can be captured
(this is important e.g. for settings in Zoneminder) - audio capturing from the 8000Hz Easycap
The stk1160 driver doesn't support audio on
the four CVBS model and on
the the CVBS + S-Video model where the AC'97 chip is missing.
(Adding support for the 8 bit ADC in the stk1160 chip is planned in the future.)
Hi Andrew.
ReplyDeleteI have 2 easycaps, one of each type ( 4rca and s-video ). In a laptop with ubuntu 13.04 the 4 channels easycap works but the other not (the s-video) only the audio input seems to work. Of course not at the same time.
I tried with both drivers stk1160 and easycap.
Update:
DeleteOther thing, i have other laptop with ubuntu 10.04 and the driver easycap0.9 and works the 2 models of easycap. The only problem was the bar=1 option in the config of the driver and the easycap CVBS + S-Video work.
Hi Edward, your problem sounds like the "stk1160 regression problem"
DeleteRead this post on my blog:

Can you send me over the easycap.log file (one for each plugged in device) which is created by the following command, so I can look if I find some reason for your problem, or I'll send it over to Ezequiel Garcia.
run this command in the terminal and send it to me as email attachment (adress is in my profile)
