The Imaging Source and INDI #42237
Hey,
I know, TIS cameras can be controlled via the V4L2 driver, but I'm kinda dissatisfied with its streaming performance and there seem to be a few more bugs concerning the communication of INDI with the camera.
Is this known? Are there any workaround? At the moment the maximum FPS I get is around 1.5 which is unsatisfactory knowing that qv4l2 makes 15 to 30 FPS with the same setup.
And if there is no workaround or way to improve this, is there a chance to build up a driver based on the TIS linux library ? Although I don't really know, if this adresses the actual problem behind the low frame rate since v4l2 does not seem to be the problem.
Greetings and big thanks in advance!
Cheers
Erik

or you can ask the imaging source to develop an INDI driver for their cameras? It might be a long shot but with enough users asking...

I asked and it doesn't seem like they are willing to do the development work for an TIS INDI driver based upon their linux SDK. :D I know, it was just me asking yet, but I kinda got the feeling, that they thought someone from the INDI community will be willing to do the job.

Sooo, I'll probably give it a try, because the half a frame per seconds streaming doesn't even come close to my expectations and I kind of want that driver in near future.

Does anybody already have some experience with the TIS SDK? Comments and hints appreciated!

Cheers
Erik

So, for some reason the FPS with the new Ubuntu 18.04 version works now fine with the v4l2 driver and my The Imaging Source camera.
What I'd like to implement nonetheless, is the additional properties such as i. e. the Trigger Mode, ( see under section "Interface (electrical)" ). Since it would allow to generate very accurate timestamps in connection with an GPS device.

What would be the most convenient way to inherit from the V4L2_Driver class? Forking the INDI main repository and adding it or maybe going into the 3rd party and making an The Imaging Source driver, since these trigger features will only work for some of their cameras?

Thanks in advance

Cheers
Erik

Probably 3rd party is the way to go here, though I'm not sure how well the V42L is exposed to 3rd party drivers at the time being.

Okay. Forked the 3rd party drivers already. A quick glance revealed that the header files for the V4L drivers aren't yet added to the include folders.

Right, let us know what needs to be done to get this in order. Like what we did with the LX200 library.
