from Peter Frühberger
Sorry, to warm up this thread. I have also seen that 24p playback is now "working" again. If one measure the audio vs the video clock. One is approx 10ms behind per 6 seconds, which is compensated by "Duplicating package" or "resampling" if your player supports this. On 50hz I am 10ms too far ahead per 6 seconds. This cause for example LiveTV to run out of packages. I compared every register with fglrx I could find and there is no real difference between those two. Log example with xbmc syncing to video clock (50hz): 15:15:58 T:139930428761856 WARNING: CDVDMessageQueue(audio)::Get - asked for new data packet, with nothing available 15:16:04 T:139930428761856 WARNING: Previous line repeats 6 times. 15:16:04 T:139930428761856 DEBUG: CDVDPlayerAudio:: Discontinuity2 - was:53826205859.132309, should be:53826216146.139511, error:10287.007199 15:16:04 T:139930428761856 WARNING: CDVDMessageQueue(audio)::Get - asked for new data packet, with nothing available 15:16:10 T:139930428761856 WARNING: Previous line repeats 10 times. 15:16:10 T:139930428761856 DEBUG: CDVDPlayerAudio:: Discontinuity2 - was:53832387675.043510, should be:53832398035.209015, error:10360.165502 15:16:12 T:139930428761856 WARNING: CDVDMessageQueue(audio)::Get - asked for new data packet, with nothing available 15:16:17 T:139930428761856 WARNING: Previous line repeats 7 times. 15:16:17 T:139930428761856 DEBUG: CDVDPlayerAudio:: Discontinuity2 - was:53838568755.002014, should be:53838579138.448776, error:10383.446764 15:16:17 T:139930428761856 WARNING: CDVDMessageQueue(audio)::Get - asked for new data packet, with nothing available 15:16:23 T:139930428761856 WARNING: Previous line repeats 16 times. 15:16:23 T:139930428761856 DEBUG: CDVDPlayerAudio:: Discontinuity2 - was:53844735030.241776, should be:53844745675.325325, error:10645.083549 15:16:23 T:139930428761856 WARNING: CDVDMessageQueue(audio)::Get - asked for new data packet, with nothing available Log with 24p: 12:00:37 T:140730861328128 DEBUG: CDVDPlayerAudio::Discontinuity2 - was:246782652.089114, should be:246769963.622166, error:-12688.466948 12:00:45 T:140730861328128 DEBUG: CDVDPlayerAudio::Discontinuity2 - was:254909959.765166, should be:254897679.533340, error:-12280.231826 12:00:53 T:140730861328128 DEBUG: CDVDPlayerAudio::Discontinuity2 - was:263037680.565340, should be:263025287.637961, I tried to play with register 0x05b4 and 0x05b8 but could not find a ratio so that the drops would stop. Not sure if this is related to the original problem though. Btw. you won't notice this problem, if you play local content and for example resample audio.
