• Video upload size

  16 mai 2014, par Jonas m

  I’m having a hard time figuring this one out, so hopefully, some of you who has tried this before, will take the time to reply and share your knowledge.

  I’m working on a site, which after release, will be feeded in the television and other commercial places. The site asks the user to upload a video with a story, and we expect alot of people to do so.

  My problem is the whole storage/space talk. A normal, unencoded iPhone recording easily fills around 100-120 MB for a minute or two.

  I’ve tried setting up and using FFMPEG to re-encode the movies, but the problem is, that one encoding sucks up 100% of the CPU, leaving the site inaccisible for anybody else.

  Is there anything you could suggest, which would be sufficient for such a site ? The client is on a budget, so price is a consideration aswell. Best of all would be a free alternative to etc. FFMPEG, but with less CPU usage.

  My specs are as follows
  CentOs 6 on a
  1GB ram DigitalOcean cloud service with nginx + php-fpm and mysql.

  Im hoping for some cleaver folks to answer this !
  Thanks in advance.

• select output colospace in ffmpeg's stagefright codec

  7 juin 2013, par Javier

  I'm new here so first of all, i'd like to say that this is an awesome comunity :-). Well, let's start with my question.

  Currently, I'm working with an embbeded systems (freescale imx6 and exynos 4412 based processors). The main idea is to develop a voip app with HD video (1080p) for Android. The video is captured via H264 hardware webcam (logitech c920). Until now, I'm able to use the ffmpeg's libstagefright codec, it works really fine and faster but I have the problem that lots of people have. "The colorspace conversion".

  As I can see in the code,

  outFormat = (*s->decoder)->getFormat();
  
  outFormat->findInt32(kKeyColorFormat, &colorFormat);

  We can get the output colorspace format, but my question is :

  Could I define other output colorspace format ? How ?

  If I were able to perform this task via stagefright (because the vendors provides the hardware accel by this way) I could overcome the colorspace conversion time penalty when I perform this task via OpenGL.

  Thank you !

• Usage with FFMPEG on a vServer ?

  28 février 2020, par MaxChri

  Heyo !

  I’m just setting up a video platform for a small project. So far a user is able to upload a video in any common format. The video will be converted using FFMPEG.

  ffmpeg -i input.mp4 -vcodec h264 -acodec aac -strict -2 output.mp4

  At the moment I’m testing all the stuff on my 3€ testserver which is actually pretty slow. But imagine, a 10 seconds 60fps full hd video takes like 6 minutes of converting. I think I’m not able to run this configurations on a live version. :D

  My current test setup :
  vCPU 1x (Events per second : 175)

  So my question is, which cpu should I use ? I searched for a server on hetzner. The setup with dedicated vCPU is especially declared for video converting. But the cpu benchmark is not much better with 600 events per second while the price is around 20€.

  What do I need to convert a 10 min video (full hd 60fps) in just 1-2 minutes ? My budget should be around 30€/m.
