DunnoX Posted March 12, 2013 Share Posted March 12, 2013 Hi i have DVBViewer 5.0 and lavfilters installed, when i try to watch the 4k resolution test channel on hispasat it skips a little (like jumping frames), it playbacks fine on DVBViewer if recorded.So why does live 4k skip frames and if recorded playbacks flawlessly.

If yes, your pc lacks power. The live stream won't wait for the decoder -> frames are skipped. Playback can be performed at a reduce speed Quote Link to comment
DunnoX Posted March 12, 2013 Author Share Posted March 12, 2013 Lav is with hardware accelaration on and vlc the live stream runs flawless.And if record the channel and playback DVBViewer doesn't skip frames, while watching processor is at 20% . My specs are: Processor I3-530 Graphics Nvidia GT 610 Ram 4G Tuner Technisat Skystar USB HD OS Windows 8 x64 Quote Link to comment

Derrick Posted March 12, 2013 Share Posted March 12, 2013 I think I know the reason but I don't know how to fix it. The problem seems to be the audio track. Since I 1st tried the 4k demo they've changed the video and audio parameters. The layerIII audio doesn't connect. Try a different audio codec. Maybe you won't hear anything but the buffer overflows will disappear Quote Link to comment
DunnoX Posted March 12, 2013 Author Share Posted March 12, 2013 Just ran vlc with verbosity on warnings and you seem to be right: vlc dump: main warning: buffer way too early (-268758), clearing queue main warning: audio output out of sync, adjusting dates (-49603 us) main warning: not synchronized (-49603 us), resampling main warning: buffer too early (-49603), down-sampling main warning: picture is too late to be displayed (missing 78 ms) Quote Link to comment
