• FFMPEG RTMP stream that is recorded by Nginx loses quality

  The stream that that is pushed the stream into nginx looks great ! But the nginx recording looks very granny and pixelated. What could be causing the loss in quality as nginx records the stream ?

  


• FFMpeg on Android : Streaming HTTP audio stream

  21 février 2012, par ebarch

  I'm having an issue being able to open streams with FFMpeg on Android. I downloaded the FFMpeg code from http://bambuser.com/opensource and compiled it without any issues. I tried adding —enable-protocol=http to the build options and then wrote some test JNI to setup the stream.

  When calling av_open_input_file with the URL to a valid HTTP MP3 stream, I'm always receiving -2 (No such file or directory) back as the error code. I've seen other projects that use this method to open streams, so I'm thinking it has to do with my FFMpeg build.

  Any help would be greatly appreciated !

  Some (Solaris) systems apparently have an incompatible msghdr struct
