#13543: Corruption of recordings seems to be linked to system events
--------------------------------------+--------------------------
Reporter: jpilk | Owner: (none)
Type: Bug Report - General | Status: new
Priority: minor | Milestone: needs_triage
Component: MythTV - General | Version: Master Head
Severity: medium | Keywords:
Ticket locked: 0 |
--------------------------------------+--------------------------
New recordings from DVB-T with EIT have packets out of order at times that
seem to be related to scheduling or perhaps other system events. When
processed by Project-X this causes drops of individual GOPs from files
that otherwise play well.
