• Streaming Installation paid request [on hold]

  9 février 2016, par Lewis Tyler

  Basically I need a streaming platform which allows my users to broadcast their webcam to a rtmp ip each users would have there own link rtmp://192.168.0.1/username/token I just need the server ip. No installation required. Does anyone know of any good sites to purchase a streaming server like this? Or can anyone set one up for me over team viewer on my own remote server, happily to pay someone for their time.

• mp4 video on Android

  9 février 2016, par matthewbaskey

  I wanted to convert some old Flash videos to 1 video format so the content will show on a mobile phone. I got some mp4 and it doesn't work on Android, specifically Chrome 32 running on Android 4.3.

  Click this link to a fiddle

  It is loading the mp4 file on Chrome 32 on Android 4.3, but I thought there is no support for H.256

  Then I went to a this site http://techslides.com/sample-webm-ogg-and-mp4-video-files-for-html5/

  and the mp4 video there works on Android/Chrome.

  I used VLC to check the codecs and they look the same

  H264 - MPEG-4 AVC (part 10) (avc1)
  Resolution: is different (working one is 560x320
  Resolution: mp4 not working is 640x480
  Framerate: working is 30, not working is 12
  Decoded format: Planar4:2:0 YUV
  

  I then searched the codec then with ffmpeg and I see that there is a property called compatible_brands: mp42icomavc1

  which is different than the non-working mp4 which has this property set to compatible: mp42mp41

  The file sizes are quite different as well. Could this be an issue.

  When I load http://html5test.com the Chrome on Android browser says MPEG-4 is not supported by H.264 is. it doesn't say anything about the container.

  ok here is some source code, I thought chrome on android doesn't support mp4 files, but when I load the following on Chrome 32 running on Sony Xperia Tablet running Android 4.3. I had an mp4 file that I converted to webm, but chrome still could not run it. It is 8 MB so perhaps the size is an issue....this mp4 has a different size and frameframe. Other than that I only see compatible version different as mentioned above.

• cakephp FFMPEG Library to convert mov file into mp4 for iphone to android video issue

  9 février 2016, par Tarunn

  I am on cakephp 2.3 and with my API, the video recorded from iPhone is not playing well in some android devices. So after wasting 2 week and with the help of community the solution was to convert this mov into mp4 on server, ffmpeg lib was suggested.

  I had installed ffmpeg lib, I am looking for any cakephp 2.3.* version package which works/converts with ffmpeg?

  The other way I have is to use php exec and convert the video without php library.

  Any suggestion/feedback welcomed.

• FFmpeg creating a slideshow from images in different folders

  9 février 2016, par Zahlii

  I am storing images of my webcam in a tree-like structure, e.g. img/2016/02/09/%h_%m_%s.jpg.

  Now I want to create a slideshow out of them using FFmpeg - one way (that I am doing right now) is downloading the images, batch-renaming them and running FFmpeg locally, just to upload the video again. Big drawback: I have to do it manually and upload/download loads of images.

  I am using the given code:

  @echo off
  setlocal EnableDelayedExpansion
  set i=0
  for %%a in (*_*_*.jpg) do (
      set /a i+=1
      ren "%%a" "img-!i!.new"
  )
  ren *.new *.jpg
  ffmpeg -framerate 60 -i "img-%%d.jpg" out.mp4
  pause
  

  Now I was wondering if I could run this on the server where the images are stored. It is no problem to generate a list of the required images, but I don't see any option to use FFmpeg to run across images located in different folders.

  I am looking for an option similar to ffmpeg - i "2015/09/01/01_01_00.jpg,2015/09/01/01_02_00.jpg,..."
