V4L2 TS output devices support, is there any interest?

You could then use such devices to control an external STB through your enigma2 box and display them like standard enigma2 services in bouquet list.
Hauppauge HD PVR features H.264 hardware encoder, older Hauppauge WinTV PVR USB2 features MPEG2 hardware encoder.

I am already using such setup with HTPC and MythTV, I will try to implement it in E2.

I have no use for it myself, but I think the idea is interesting.

I always wonder whether a pure hardware "solution" might be better at this. To start with, does this device also take digital input, like yuv4mpeg frames? AFACS it only takes analog input, which is a shame imho.
My DSLR and video camera also record in h264, but the resulting files are quite disappointing in efficiency. If the resulting files are re-encoded using libx264, using same visual quality, the size drops to about 25-10%. So I guess hardware "solutions" are not that favourable after all

As for your encoder, it might help to buy a modern "budget" video card. With appropriate software and drivers, the newer models can also assist in encoding H264 video in addition to decoding. So they claim. No personal experience with that, I just use the card for gaming.

You will need microsoft windows for proper support though (trust me, been there...).As for your encoder, it might help to buy a modern "budget" video card. With appropriate software and drivers, the newer models can also assist in encoding H264 video in addition to decoding. So they claim. No personal experience with that, I just use the card for gaming.
Also Intel itself has no real plans to support the encoder capabilities in Ivy Bridge / Sandy Bridge cpu's in Linux. Bastards. Accelerated video decoding does work more or less, but you have to jump through a lot of hoops to get it actually working, it's certainly NOT out of the box.
So I guess I will have to stick to libx264 for the next few years (which does an excellent job, btw).

Having programmed for both platforms, I can understand why they don't want to invest in proper Linux support...

Closed source drivers are out of the question when you're using (like me) self-compiled kernels.The decoder for my ATI card works fine in Ubuntu, installing the (closed source) driver was quite easy for as far as installing a driver in Linux is ever easy...

Anyway, they do not even need to produce anything, they only need to disclose the data!

Are you thinking in the line of an 'usbtunerhelper', which does rougly the same, pump external TS into a vtuner device, or are you thinking about a 'servicedvb' derivate in e2 itself, which pumps the data to a dvr device?
in e2, with the dvr device, would be the simples aproach to start with I guess, but with vtuner you might even be able to integrate the ir, and make the external stb behave like an actual virtual tuner, to e2.

Not necessarily true. I compile my own kernels on Ubuntu and the fgrlx closed-source driver works well (or at least as well as any Ati linux driver). If you generate the .deb packages from the self-compiled kernel, the fgrlx module is built automagically when you install the new kernel packages.

I have tried to install the nvidia binary only driver on my laptop and failed miserably.
