I get distortions in the mpeg streams sometimes even no audio. This happens round about every 5 - 30 seconds. It is the same mysql-database and the same configuration as before. I don't think it could be performance related, as CPU's are below 20%. No IOWait in top. Slowdelete activated. I have got DVBS2, driver is vdpau. I also tried different deinterlacers and even deactivating it, no change. I haven't found any mpeg related error in the log, only strange entry is about unknown AFD ID's, but I am not sure, if that's related. Another interesting entry is: ""[dsmcc] Dropping block size 4096 with tag 21, carouselID 11, dataBroadcastID 0x123"" see: ---------------------- 2014-06-26 22:57:49.973112 I MythSocket(35d2140:86): read <- 86 4 3640 2014-06-26 22:57:49.991958 I MythSocket(35d2140:86): write -> 86 39 QUERY_RECORDER 5[]:[]GET_FRAMES_WRITTEN 2014-06-26 22:57:49.992608 I [dsmcc] Dropping block size 4096 with tag 21, carouselID 11, dataBroadcastID 0x123 2014-06-26 22:57:49.992659 E AFD: VBI: Unknown descriptor: 44 2014-06-26 22:57:49.992870 I MythSocket(35d2140:86): read <- 86 4 3640 2014-06-26 22:57:49.992938 E AFD: VBI: Unknown descriptor: 44 2014-06-26 22:57:49.993164 I [dsmcc] Dropping block size 4096 with tag 20, carouselID 10, dataBroadcastID 0x123 2014-06-26 22:57:49.993177 E AFD: VBI: Unknown descriptor: 44 2014-06-26 22:57:49.993177 I [dsmcc] Dropping block size 4096 with tag 21, carouselID 11, dataBroadcastID 0x123 2014-06-26 22:57:49.998054 I RingBuf(/MEDIA/video/live-tv/11301_20140626205637.mpg): safe_read(...@3030428, 458752) -> 190068, took 0 ms (1000Mbps) avg 183 ms ---------------------- If you can give me some advice, how I could narrow analysis down, that would be great?
