• Can red5 be used instead of FFmpeg in Android ?

  3 septembre 2012, par Balwant Kumar Singh

  Can I use red5 as my native library instead of FFmpeg for Android ? I was told that FFmpeg resides inside red5. I'm not able to see the documentation of red5 because the red5 server is down.

• Truly live streaming to Android/iPhone

  4 juillet 2012, par Tsaukpaetra

  I have spent quite a while (past week) trying this to little avail. However, what I want seems completely unheard of. So far, I have reviewed recommendations available through google, which include encoding a static file into multiple static files in different formats, creating a playlist that hosts static files in an m3u8 file (files which get added to the playlist as streaming continues).
  I have also seen ideas involving rtmp, rtsp etc which are completely out of the question because of their incompatibility.
  Ideally, I would have one webpage that would link to the stream (http://server/video.mp4) and/or show it in a webpage (via the video tag). With that in mind, the most likely format would be h264+aac in mp4 container.

  Unfortunately, (and probably because the file has no duration metadata) it does not work. I can use a desktop player (such as VLC) to open the stream and play it, but my iPhone and Android both give their respective "Can't be played" messages.

  I don't think the problem is caused by the devices' ability to stream, for I have made a streaming shoutcast server work just fine (mp3 only).

  Currently, the closest I have become is using the following setup on my win32 machine :

  FFMPEG Command: : ffmpeg -f dshow -i video="Logitech Webcam 200":audio="Microphone (Webcam 200)" -b:v 180k -bt 240k -vcodec libx264 -tune zerolatency -profile:v baseline -preset ultrafast -r 10 -strict -2 -acodec aac -ac 2 -ar 48000 -ab 32k -f flv "udp ://127.0.0.1:1234"

  VLC: : Stream from udp ://127.0.0.1:1234 to http:// :8080/video.mp4 (No Transcoding), basically just to convert the UDP stream into an http-accessible stream.

  Any hints or suggestions would be warmly welcomed !

• How to enable HW decoder via Stagefright in FFmpeg Android port

  29 juin 2012, par vitakot

  I have created a media player based on FFmpeg, it works well, but I need to enable HW decoder. I am trying to compile FFmpeg with Stagefright support – using prepared build script in FFmpeg/tools directory. It compiles fine without any error. I have all libraries. The problem is that once I link resulting libraries with my player I am getting an exception when trying to load it :

  java.lang.UnsatisfiedLinkError: Cannot load library: reloc_library[1314]:  1269 cannot locate '__aeabi_lasr'...

  Without that support everything works perfectly.

  Somebody had a similar problem here. But the solution does not work for me.

  I also changed a build script a bit according to this one - added --extra-libs="-lgcc" and –nostdlib, but nothing changed.

  Has anyone made it working ? There is no readme, no clue, just a build script and that’s all...
