You may want to find out where this message comes from (it certainly doesn't come from the core VDR). > [vAVM]buffered 7.1 frames (v:12.2, a:7.1) > SetPlayMode: 0 > Slot 2: ==> Ca Pmt (3) 5 1 > 2: --> 00 01 A0 16 01 90 02 00 03 9F 80 32 0D 05 03 ED 01 00 07 01 > 09 04 06 06 E4 54 > Slot 1: ==> Ca Pmt (3) 4 1 > 1: --> 00 01 A0 20 01 90 02 00 03 9F 80 32 17 04 03 ED 01 00 07 01 > 09 04 06 06 E4 54 02 05 19 00 00 04 05 7D 00 00 > SetPlayMode: 1 > [v] > DiscontinuityDetected: triggering soft start > [vAVM]buffered 7.3 frames (v:13.0, a:7.3) > SetPlayMode: 0 > Slot 1: ==> Ca Pmt (3) 5 1 > 1: --> 00 01 A0 16 01 90 02 00 03 9F 80 32 0D 05 03 ED 01 00 07 01 > 09 04 06 06 E4 54 > Slot 2: ==> Ca Pmt (3) 4 1 > 2: --> 00 01 A0 20 01 90 02 00 03 9F 80 32 17 04 03 ED 01 00 07 01 > 09 04 06 06 E4 54 02 05 19 00 00 04 05 7D 00 00 > SetPlayMode: 1 > [v] > > and in messages: > Aug 28 12:50:10 freddy vdr: [16633] receiver on device 2 thread started > (pid=16557, tid=16633) > Aug 28 12:50:10 freddy vdr: [16634] TS buffer on device 2 thread started > (pid=16557, tid=16634) > Aug 28 12:50:11 freddy vdr: [16633] cVideoRepacker: switching to MPEG1/2 > mode > Aug 28 12:50:11 freddy vdr: [16633] cVideoRepacker: operating in MPEG1/2 > mode > Aug 28 12:50:14 freddy vdr: [16634] TS buffer on device 2 thread ended > (pid=16557, tid=16634) > Aug 28 12:50:14 freddy vdr: [16633] buffer stats: 192700 (9%) used > Aug 28 12:50:14 freddy vdr: [16633] receiver on device 2 thread ended > (pid=16557, tid=16633) > Aug 28 12:50:21 freddy vdr: [16557] switching to channel 1 > Aug 28 12:50:21 freddy vdr: [16635] receiver on device 1 thread started > (pid=16557, tid=16635) > Aug 28 12:50:21 freddy vdr: [16636] TS buffer on device 1 thread started > (pid=16557, tid=16636) > Aug 28 12:50:22 freddy vdr: [16635] cVideoRepacker: switching to MPEG1/2 > mode > Aug 28 12:50:22 freddy vdr: [16635] cVideoRepacker: operating in MPEG1/2 > mode > Aug 28 12:50:25 freddy vdr: [16636] TS buffer on device 1 thread ended > (pid=16557, tid=16636) > Aug 28 12:50:25 freddy vdr: [16635] buffer stats: 173712 (8%) used > Aug 28 12:50:25 freddy vdr: [16635] receiver on device 1 thread ended > (pid=16557, tid=16635) > > i.e. I get 3 second "bursts" of live TV, but blank screen as the > receiver threads restart > > Why am I getting a "SetPlayMode: 0" and "receiver on device 2 thread > ended (pid=16557, tid=16633)" for no reason?? When a receiver is detached from a device, the play mode is set to pmNone (which is 0). My guess would be that the "DiscontinuityDetected: triggering soft start" is generated by the output device, and that causes the transfer mode to be stoped and restarted. Maybe the output device chokes on something in the TS stream?
