F4vpp does not handle files over 2GB?

Tags: #f4vpp

Hi everyone,

 

We use f4vpp to process MP4 files after they are recorded by FMS. A couple of times now we have noticed that the output of f4vpp stops at exactly 2GB.

 

Have others here seem this same problem? Is this a limitation of f4vpp? Is it a bug or dependent on our system perhaps?

 

In case it matters: we use f4vpp on linux.

 

I hope someone can shed some light on this soon as this is really inconvenient. Thanks in advance for any help.

    Hi GRO_NIC - sorry for delay in reverting - i was off - just give me couple of days and i'll revert to for sure. Dont worry its on my radar and not slipped - its just that there were few other things my way.

    Yes i had been in discussion with Developers but i fell sick and could not get back to you. As per them there should not be any differnece between Windows and Linux executables. I would have liked to try it myself - does it happen with nay file greater than 2GB on linux or only this specific file - is it possible for you to host it somewhere from where i can download it.

    will f4vpp work on files that are DRM encoded?  I have not been able to get it to work on this one file I need to convert but I think it is the DRM that stops f4vpp from working?  thanks in advance

    use ffmpeg, it is a lossless conversion to .mp4 or .f4v.. Alternatively you can set diskmanagement and segmentduration to null in Application.xml to create 1 .mp4 or .f4f file eliminating the need to package all of segments into 1 file.   You can t hen also use ffmpeg on the 1 segment file to convert to .mp4 or .f4v losslessly as well to remove keyframe interval metadata.
