Config:\r\nvdr 2.2.0 -> vdr-plugin-dvbapi (git master) -> oscam 1.20-10887 -> smargo reader -> smartcard (official M7/TV Vlaanderen).\r\nAll on the same host.\r\n\r\nLately one DVB card broke down and I decided to replace it with an Inverto/Grundig/Telestar idl4k SAT>IP device (Telestar Digibit R1).\r\n\r\nThe satip device (firmware 1.17) + vdr-plugin-satip works totally fine for FTA broadcasts. Recording 3 HD channels using three tuners + streaming 2 HD channels live from the same transponder: not a sweat.\r\n\r\nHowever, when I do something less stressing with encrypted channels, it does not take long for artefacts to appear. E.g. recording 2 HD channels and watching 1 live works for a couple of minutes, but usually one of them starts experiencing severe video and sound artefacts.\r\n\r\nI've tried different satip firmwares (1.16, 1.17, and https://github.com/perexg/satip-axe/) as well as different vdr hardware (dual and quad core Intel systems with 2 and 4GB RAM and a fast disk).\r\n\r\nI'm suspecting there is some buffering going on and some data is occasionally being dropped for an unknown reason.\r\n\r\nI've monitored the oscam logs and I don't see anything unusal (found always within 250-350ms).\r\n\r\nCan you make a suggestion how to proceed troubleshooting or what buffers may be in play here and how I can tune them?\r\n\r\nThanks, and thanks for the fine plugin."},"comment":{"url":"https://api.github.com/repos/manio/vdr-plugin-dvbapi/issues/comments/114441981","html_url":"https://github.com/manio/vdr-plugin-dvbapi/issues/95#issuecomment-114441981","issue_url":"https://api.github.com/repos/manio/vdr-plugin-dvbapi/issues/95","id":114441981,"user":{"login":"pvdputte","id":6298967,"avatar_url":"https://avatars.githubusercontent.com/u/6298967?v=3","gravatar_id":"","url":"https://api.github.com/users/pvdputte","html_url":"https://github.com/pvdputte","followers_url":"https://api.github.com/users/pvdputte/followers","following_url":"https://api.github.com/users/pvdputte/following{/other_user}","gists_url":"https://api.github.com/users/pvdputte/gists{/gist_id}","starred_url":"https://api.github.com/users/pvdputte/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/pvdputte/subscriptions","organizations_url":"https://api.github.com/users/pvdputte/orgs","repos_url":"https://api.github.com/users/pvdputte/repos","events_url":"https://api.github.com/users/pvdputte/events{/privacy}","received_events_url":"https://api.github.com/users/pvdputte/received_events","type":"User","site_admin":false},"created_at":"2015-06-23T10:48:00Z","updated_at":"2015-06-23T10:48:00Z","body":"Actually, I come from mythtv + vdr-sasc-ng and I was very very pleased with VDR after making the jump. No broken channel scanner anymore but just a channels.conf file etc. :-)\r\n\r\nThe hardware is actually quite nice for the price, and alternative firmware like https://github.com/perexg/satip-axe/tree/master/dist opens many possibilities.\r\n\r\nI'll look into https://github.com/catalinii/minisatip/issues/21 as I see mention of a vdr 'decode buffer' and 'buffer stats' log messages, maybe I can learn something from that if I increase logging. (I already tried the network buffer thing but no luck)\r\n\r\nIf I can't find anything I'll have to buy another PCI card I'm afraid.\r\n\r\nThank you for your time!"}}
