From 1cb662a3144992259edfd3cf9f54a6b25a913a0f Mon Sep 17 00:00:00 2001 From: Andreas Oberritter Date: Tue, 14 Jul 2009 20:28:50 -0300 Subject: V4L/DVB (12275): Add two new ioctls: DMX_ADD_PID and DMX_REMOVE_PID DMX_ADD_PID allows to add multiple PIDs to a transport stream filter previously set up with DMX_SET_PES_FILTER and output=DMX_OUT_TSDEMUX_TAP. DMX_REMOVE_PID is used to drop a PID from a filter. These ioctls are to be used by readers of /dev/dvb/adapterX/demuxY. They may be called at any time, i.e. before or after the first filter on the shared file descriptor was started. They make it possible to record multiple services without the need to de- or re-multiplex TS packets. To accomplish this, dmxdev_filter->feed.ts has been converted to a list of struct dmxdev_feeds, each containing a PID value and a pointer to a struct dmx_ts_feed.
