• libvpx doesn't create .pc files

  17 novembre 2013, par olgash

  I'm trying to compile ffmpeg with libvpx. Libvpx compiles nicely, with no errors other than it couldn't create debug for win32 because I don't have visual studio 8 (which I think is fine ?), but it doesn't create any .pc file in MinGW's lib folder (which all of the other libraries I've installed do).

  When I run ./configure —disable-encoder=vorbis —enable-libvorbis —enable-libvpx —prefix=/MinGW on ffmpeg, it always says my version of libvpx is too old even though I'm using 1.2.0. I'm not sure what to do here, help ?

• streaming a webcam feed over rtsp using ffmpeg & ffserver to an android client

  26 juillet 2015, par Coyote

  I am trying to stream my webcam over rtsp and open the stream using android.
  I managed to get the first part working (rtsp stream) using ffserver and ffmpgeg. Here is my ffserver.conf file :

  HTTPPort 8000
  
  RTSPPort 8001
  
  HTTPBindAddress 192.168.1.74
  
  RTSPBindAddress 192.168.1.74
  
  MaxClients 100
  
  MaxBandwidth 10000
  
  NoDefaults
  
  
  
  <feed>
  
     File /tmp/witty.ffm
  
     FileMaxSize 20M
  
  </feed>
  
  
  
  <stream>
  
     Feed witty.ffm
  
     Format rtp
  
     VideoSize 640x480
  
     VideoQMin 1
  
     VideoQMax 20
  
     VideoFrameRate 30
  
     VideoBitRate 500
  
     AVOptionVideo flags +global_header
  
     VideoCodec libx264
  
     AVPresetVideo baseline
  
     NoAudio
  
  </stream>

  ffserver :

  ffserver -f -d ffserver.conf // luch the server

  and then I use FFmpeg to open the webcam (Mac OS)

  ffmpeg -f avfoundation -i "default" http://192.168.1.74:8000/witty.ffm

  I can open the stream from VLC but on android using a videoView i am getting an error (1,-38) and an alert view saying "can’t play this video".

• RTSP streaming on Android client using FFMpeg

  7 février 2021, par rurtle

  I am working on a hobby project the goal for which is to develop an Android application capable of streaming live feeds captured through web cams in a LAN setting using FFMpeg as the underlying engine. So far, I did the following -

  



  A. Compiling and generating FFMpeg related libraries for the following releases -

  



  FFMpeg version : 2.0
  
NDK version : r8e & r9
  
Android Platform version : android-16 & android-18thisthisthisthis
  
Toolchain version : 4.6 & 4.8
  
Platform built on : Fedora 18 (x86_64)
  

  



  B. Creating the files Android.mk & Application.mk in appropriate path.

  



  However, when it came to writing the native code for accessing appropriate functionality of FFMpeg from the application layer using Java, I'm stuck with following questions -

  



  a) Which all of FFMpeg's features I need to make available from native to app layer for streaming real-time feeds ?
  
b) In order to compile FFMpeg for Android, I followed this link. Whether the compilation options are sufficient for handling *.sdp streams or do I need to modify it ?
  
c) Do I need to make use of live555 ?
  

  



  I am totally new to FFMpeg and Android application development and this is going to be my first serious project for Android platform. I have been searching for relevant tutorials dealing with RTSP streaming using FFMpeg for a while now without much success. Moreover, I tried the latest development build of VLC player and found it to be great for streaming real-time feeds. However, it's a complex beast and the goal for my project is of quite limited nature, mostly learning - in a short time span.

  



  Could you suggest some pointers (e.g. links, documents or sample code) on how can I write the native code for utilizing FFMpeg library and subsequently use those functionality from the app layer for streaming real-time feeds ? Moreover, will really appreciate if you could let me know the kind of background knowledge necessary for this project from a functional standpoint (in a language agnostic sense).
