I try to play a file, but mplayer gives me this: ======= WAVE Format ======= Format Tag: 309 (0x135) Channels: 2 Samplerate: 8000 avg byte/sec: 2181 Block align: 11 bits/sample: 0 cbSize: 0 =========================== demux_audio: audio data 0x3A - 0x8A0D2 Audio file detected. ========================================================================== Cannot find codec for audio format 0x135. Read DOCS/HTML/en/codecs.html! Google tells me that 0x135 is Sipro Lab Telecom ACELP.KELVIN. Anyone have any idea where I can find a codec to decode audio in this format? Or, if there is a more appropriate place to ask? thanks, -wes
