cb889a2f35 V4L/DVB (10164): Add missing S2 caps flag to S2API
The attached patch adds a capability flag that allows an application
to determine whether a particular device can handle "second generation
modulation" transponders. This is necessary in order for applications
to be able to decide which device to use for a given channel in
a multi device environment, where DVB-S and DVB-S2 devices are mixed.

It is assumed that a device capable of handling "second generation
modulation" can implicitly handle "first generation modulation".
The flag is not named anything with DVBS2 in order to allow its
use with future DVBT2 devices as well (should they ever come).

e7fee0f3aa V4L/DVB (8996): S2API: typedefs replaced, _SEQ_'s removed, fixed 16 command arrays replaced
After discussion the following changes were made:
1. Removed the typedefs in frontend.h, use structures.
2. In the frontend.h, remove the 16 command limit on the API and
   switch to a flexible variable length API. For practical reasons
   a #define limits this to 64, this should be discussed.
3. Changed dvb-core ioctl handing to deal with variable sequences
   of commands.

tune-v0.0.3.c is required to use this API, it contains the interface changes.

6b73eeafbc V4L/DVB (8985): S2API: Added dvb frontend changes to support a newer tuning API
This is an experimental patch to add a new tuning mechanism for
dvb frontends. Rather than passing fixed structures across the
user/kernel boundary, which need to be revised for each new modulation
type (or feature the kernel developers want to add), this implements
a simpler message based approach, allowing fe commands to be broken
down into a series of small fixed size transactions, presented
in an array.

The goal is to avoid changing the user/kernel ABI in the future, by
simply creating new frontend commands (and sequencies of commands) that
help us add support for brand new demodulator, delivery system or
statistics related commmands.

known issues:
checkpatch voilations
feedback from various developers yet to be implemented, relating
to namespace conventions, variable length array passing conventions,
and generally some optimization.

This patch should support all existing tuning mechanisms through the
new API, as well as adding 8PSK, DVB-S2 NBC-QPSK and ISDB-T API support.

For testing and exercise purposes, see the latest tune.c tool
available from http://www.steventoth.net/linux/s2

b01cd93789 V4L/DVB (7293): DMX_OUT_TSDEMUX_TAP: record two streams from same mux, resend
Currently (in linux-2.6.24, but linux-dvb hg looks similar), the
dmx_output_t in the dmx_pes_filter_params decides two things: whether
output is sent to demux0 or dvr0 (in dmxdev.c:dvb_dmxdev_ts_callback),
*and* whether to depacketise TS (in dmxdev.c:dvb_dmxdev_filter_start).
As it stands, those two things can't be set independently: output
destined for demux0 is depacketised, output for dvr0 isn't.

This is what you want for capturing multiple audio streams from the same
multiplex simultaneously: open demux0 several times and send
depacketised output there. And capturing a single video stream is fine
not what you want: you want multi-open (so demux0, not dvr0), but you
want the TS nature preserved (because that's what you want on output, as
you're going to re-multiplex it with the audio).

At least one existing solution -- GStreamer -- sends all its streams
simultaneously via dvr0 and demuxes again in userland, but it seems a
bit of a shame to pick out all the PIDs in kernel, stick them back
together in kernel, and send them to userland only to get unpicked
again, when the alternative is such a small API addition.

The attached patch adds a new value for dmx_output_t:
DMX_OUT_TSDEMUX_TAP, which sends TS to the demux0 device. With this
patch and a dvb-usb-dib0700 (and UK Freeview from Sandy Heath), I can
successfully capture an audio/video PID pair into a TS file that mplayer
can play back.
