We stream audio via http from ffserver / ffmpeg to Angstrom Linux. The ffmpeg audio codec is PCM signed with the 16-bit small trailing pcm_s16le. The ffmpeg stream format is "wav". Both of them are allegedly supported on Android here: http://developer.android.com/guide/appendix/media-formats.html#core
VLC finds and plays the stream without any problems. The VLC "Codec Details" section says: Type: Audio, Codec: PCM S16 LE (araw) Channels: Stereo Sampling frequency: 48000 Hz Bits per sample: 16
We created a simple test application below to pick up and play a stream in Android and get this error: java.io.IOException: Failed to prepare: status = 0x1
We checked the HTTP header using HTTP Debugger Pro. Response header elements (during normal playback via VLC): [Response]: HTTP / 1.0 200 OK Pragma: no-cache Content-Type: audio / x-wav
We searched the Internet for help on this issue for more than two days and came up empty-handed. Any help would be greatly appreciated.
