V4L/DVB (7293): DMX_OUT_TSDEMUX_TAP: record two streams from same mux, resend

2008-04-24T17:07:46+00:00

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.

V4L/DVB (5893): DVB: fix includes of video.h when KERNEL is undefined

2007-07-30T19:26:27+00:00

linux/dvb/video.h uses types __u32, __s32, etc., but does not include
any header defining those when __KERNEL__ is not defined.

Fix this by including asm/types.h when __KERNEL__ is not defined.

V4L/DVB (5418): Speed is a signed 32-bit integer, not unsigned.

Negative speed values have to be allowed for reverse playback.

V4L/DVB (5402): Add vsync_field to the union in video_event for VIDEO_EVENT_VSYNC

2007-04-27T18:44:23+00:00

VIDEO_EVENT_VSYNC needs to tell the application which field it was that
received a VSYNC (odd/even/progressive). The vsync_field was added to the
union in video_event for this purpose.

V4L/DVB (5307): Add support for the cx23415 MPEG decoding features.

2007-04-27T18:43:28+00:00

The cx23415 adds some extra features that this DVB decoding API did
not support. This API has been expanded to support the required
features. Both source and binary backwards compatibility is kept
intact by these changes. So existing applications are not affected.

V4L/DVB (3727): Remove DMX_GET_EVENT and associated data structures

2006-06-25T04:57:47+00:00

The ioctl DMX_GET_EVENT has never been implemented.
I guess no software is using it because of its lack of implementation.
Future software won't use it, too, because this API doesn't make much
sense the way it is: Frontend events have their own different API.
Scrambling events can't be generated in a useful way by the hardware I
know of.

This adds the Kbuild files listing the files which are to be installed by
the 'headers_install' make target, in generic directories.
