I tried logging the output of: "xine dvb://TMF --verbose=9" and this is what happens when you tune to a new mux: 2.0s 2160kbps 0, aud 11% 2.0s 192kbps 0, on ^Mnet_buf_ctrl: vid 73% 2.0 s 2168kbps 0, aud 11% 2.0s 192kbps 0, on ^Mgot event 00000065 ao_flush (loop running: 1) input_dvb: status: 1f input_dvb: Tuner status: FE_HAS_SIGNAL FE_HAS_VITERBI FE_HAS_SYNC input_dvb: Bit error rate: 606 input_dvb: Signal strength: 10537 input_dvb: Signal/Noise Ratio: 54227 input_dvb: Unable to achieve lock at 786000000 Hz input_dvb: tuner_set_channel failed input_dvb: reading 18800 bytes... input_dvb: got 0 bytes (0/18800 bytes read) input_dvb: got 0 bytes (0/18800 bytes read) input_dvb: got 0 bytes (0/18800 bytes read) input_dvb: got 0 bytes (0/18800 bytes read) input_dvb: got 0 bytes (0/18800 bytes read) input_dvb: got 0 bytes (0/18800 bytes read) input_dvb: got 0 bytes (0/18800 bytes read) input_dvb: got 0 bytes (0/18800 bytes read) -------------------------------------- I think this could be a problem to do with kernel latency. There have been some latency improvements in 2.6.11 and this may have had an effect on timing out. I managed to change channel successfully once while the system was under load (logging to text file) ---------------------------------------------------------------------- >Comment By: Phil Costin (philipcostin) Date: 2005-04-30 23:08 Message: Logged In: YES user_id=726105 Update: Seems to be fixed as of 1.01 ---------------------------------------------------------------------- Comment By: Phil Costin (philipcostin) Date: 2005-04-08 12:36 Message: Logged In: YES user_id=726105 Update: I have tested xine-lib-rc6a and this works. It IS possible to change channels with that version. It seems that it has something to do with the newer DVB subsystem of xine ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=109655&aid=1155429&group_id=9655 |
