  • How can I make windows "like" the mp4 files I create in Linux and sync with Rsync

    17 juillet 2019, par Geoff Fox

    I am a meteorologist on TV remotely from a studio I built. My control room uses a TriCaster, an amazing studio-in-a-box which runs on a Windows 7 variant. I make my weather maps myself on a Centos 7 machine — around 40,000/day.

    I don’t entirely understand the problem, but here’s a quote from someone helping me at NewTek (the TriCaster company)

    Rsync is built on a *nix based environment where all the file permissions and attributes are based on the Linux environment. There is no meaning for this in NTFS and Windows. The result is you get files that will most likely have the read-only flag set or no flag at all. Other attributes will be delivered as null. I’m sure from your own programming experience, programs don’t like null values and they generally have to be accounted for very specifically.

    And so the finely tuned TriCaster stumbles, meaning lost frames or other problems caused by my short weather animations.

    Here are some samples of the Rsync code I use

    rsync -r -t -s -v --no-p --chmod=ugo=rwX /var/www/html/output/loops/mp4/conus*.mp4 /mnt/tricaster/Clips/Import
    rsync -r -t -s -v --no-p --chmod=ugo=rwX /var/www/html/output/loops/mp4/nebraska*.mp4 /mnt/tricaster/Clips/Import
    rsync -r -t -s -v --no-p --chmod=ugo=rwX /var/www/html/output/loops/mp4/northernplains*.mp4 /mnt/tricaster/Clips/Import

    These are mp4 files. They are only used locally. I really don’t care what flags are checked and permissions filled as long as Windows 7 doesn’t care.

    At this point I always like to tell folks, though I do write some code my last computer class was in high school,’67-68 semester. Thanks in advance for your help.

  • How do I make sure FFmpeg generates the correct duration ?

    14 juillet 2019, par Wang

    For example, the following command creates a three-second video.

    ffmpeg -f lavfi -i color=c=red:r=30:d=3:size=800x600 red.nut

    But ffprobe shows the duration is N/A :
