I tried with the latest prebuilt-libs.tar.gz and it doesn't throw exception anymore. But the parameters do not seem to pass into FFmpeg. My app uses a RTSP source stream that use two AVOptions as follows :

 headers.put("allowed_media_types", "2");//or "audio"
 headers.put("rtsp_transport", "http");

Vitamio pass the two parameters correctly and works fine.

Do you have any idea what else need to be done to enable FMP to support these parameters?

The method signature you asked me to implement is for HTTP headers, not FFmpeg parameters.

The platform MediaPlayer use the parameter to support "Cookie" http header afaik.

The doc describes [headers](http://developer.android.com/reference/android/media/MediaPlayer.html#setDataSource%28android.content.Context, android.net.Uri, java.util.Map<java.lang.String, java.lang.String>%29) parameter as:

the headers to be sent together with the request for the data

Media Player doesn't necessary play media that use HTTP protocol obviously. Vitamio use it creatively to solve a valid problem.
