• Convert video to FLV using FFMPEG

  30 septembre 2014, par Festus Tamakloe

  I come across this code in one php script that i bought last time to convert video. The script is running on Ubuntu 12.04

  -i $file_source -b 9600k -aspect 16:9 -acodec aac -strict experimental -ab 128k -ar 22050 $file_dest" 

  That is the full meaning of elements/attributes and what could be the alternative ?

  Thanks for your help

• Live webcam stream to mjpeg file [on hold]

  20 mars 2018, par neph94

  I am looking for a way for ffmpeg or any other alternative to be able to continuously stream data to an mjpeg (or any other) file. There would be a size limitation to it. When exceeded oldest frames would just be removed to make space.

  Basically, what I am looking is ffserver with an option to stream locally to a file without serving it on an HTTP server.

• 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.
