Hello, any reason why the an encode to our custom format would sometimes cut the time? A video being 41minutes long, sometimes gets cut down to 39m, or 35m… any thoughts?

Can someone look into this? Seems like there’s really no support here :(

Please give me the video id (or source url) and the format id, so I can check it out.

Title: 6114, format ID is 2743 – and the video is http://upload2.vureel.com/video/6114.avi

I’ve just encoded this video and the video is 34min long instead of 41min. FFmpeg didn’t report any error:

I don’t know what’s going on, no warning, no error… If I find something I’ll tell you. Sorry for the inconvenience.

Our ffmpeg finds it at 41minutes :(

Yes but if you do ffmpeg -i encoded video, the duration is wrong.
