Well, that would be nice, indeed.

So, why not using FUSE, and implement a char device,
which is capable of receiving a/v streams, like e.g. the DVB devices ?

/dev/av/stream
/dev/av/es/pcm
/dev/av/es/mp123
/dev/av/es/whatever

Than, have a few ioctl's to stop/pause/reset, whatever your needs are.

I did this a long time ago under QNX,
where the device driver analyse the stream (TS/PS/ES),
demuxes it and pushes the net data to the output device,
via [oss/]alsa/mpegdecoder/../whatever.

Under QNX it was easy, since it is a mach architecture,
where you can use the user space.

Under GNU/Linux, well, we have FUSE.

Shouldn't that satisfy you ?

You can even bring this up to the V4L2 architecture ..

But without some help from the userspace, I see no land to implement
this for GNU/Linux. Since it needs decoders, etc.

Cheers, Sven
