[Support]: Recordings reporting more length by hour than the real length #9335

Describe the problem you are having

Hello everyone, how is it going? LOVING FRIGATE MORE EACH DAY HERE

I'm having an issue with my recordings. In cases where the video should be at least 3600 seconds the frigate ui reports more than expected. i know the segment time is used in ffmpeg is 10s but that gives me a maximum error of 20s in extreme cases where the segmentation cannot be exact

see the image below and you will notice that the video length is 1:00:46

that is happening with all my cameras and here it is an example of the camera's configuration and model https://drive.google.com/file/d/1wqGLV733Mf8FUU35QYFq8tvHo2KSyGOq/view?usp=sharing https://drive.google.com/file/d/11npwxDt8drR1ew2T3NSEJHg5O-ZOOkMP/view?usp=sharing

The recordings segments have to end and begin on key frames. So if your iframe times are longer that can lead to segments that are longer than 10 seconds.

i forgot to add that osd camera says the recording started at 18:59:56 and finished at 19:59:59

hello nick, i m not fully understanding how that can lengthen the video 40 seconds extra

NickM-27 commented 7 months ago

if that's the case then it means the player is not getting a perfectly accurate calculation for the video length, is this causing any actual issues or just something that was noticed?

sgrossiP commented 7 months ago

not causing any issues only displaying the wrong duration but trying to fix it and see if i am useful to this project so maybe i can push some code someday if that is the case i am closing this one :) regards

sgrossiP commented 7 months ago

adding more info to study the case cameras with no audio reports the correct length in videojs and vlc
