2008-04-24V4L/DVB (7293): DMX_OUT_TSDEMUX_TAP: record two streams from same mux, resendPeter Hartley
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.

2007-07-30V4L/DVB (5893): DVB: fix includes of video.h when __KERNEL__ is undefinedAnssi Hannula
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.

VIDEO_EVENT_VSYNC 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. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-04-27V4L/DVB (5307): Add support for the cx23415 MPEG decoding features.Hans Verkuil
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.

2006-06-25V4L/DVB (3727): Remove DMX_GET_EVENT and associated data structuresAndreas Oberritter
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. Signed-off-by: Andreas Oberritter <obi@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2005-04-16Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
