#2894: Wrong duration of the .vob files containing two titles. -------------------------------------+------------------------------------- Reporter: kasper93 | Type: defect Status: new | Priority: normal Component: | Version: git- undetermined | master Keywords: vob | Blocked By: duration | Reproduced by developer: 0 Blocking: | Analyzed by developer: 0 | -------------------------------------+------------------------------------- '''Summary of the bug:''' FFmpeg detect wrong duration of the vob files containing two titles. I'm not sure about that, but from my observations and comparing how this file is playback with MPC MPEG Splitter. I can say that real file duration is 21:34 and after 16:17 is video for other dvd title. Reproduced with multiple files. Sample: [https://dl.dropboxusercontent.com/s/asozlz6htli31ox/VTS_01_4.VOB?dl=1 VTS_01_4.VOB] Sorry for the size. Dropbox has bandwidth limit 20 GB per day. I hope that will be enough.
