So apparantly the new software you used does still have the capability to encode audio in other formats. (mplayer output for eix1.wma audio session) ============ ASF Stream group == START === object size = 32 stream count=[0x1] stream id=[0x1] max bitrate=[0x4f8a] ============ ASF Stream group == END === Clip info: name: RIPE46 Audio Stream ========================================================================== Opening audio decoder: [ffmpeg] FFmpeg/libavcodec audio decoders AUDIO: 22050 Hz, 2 ch, 16 bit (0x10), ratio: 2501->88200 (20.0 kbit) Selected audio codec: [ffwmav2] afm:ffmpeg (DivX audio v2 (ffmpeg)) ========================================================================== (checking...) Same for the routing-1 audio only session of tuesday. mms://webcast.ripe.net/ripe46/routing-1.wma ... routing-2.wma is OK too. [apart from a terrible noise some 40 seconds from the start, like someone is using a high-pressure cleaner nearby]. dn-3.wma OK. So at least for audio-only sessions your original software could encode in a supported format. If you can find the right settings to make it do that for video+audio too it might save you the trouble of digging up the old software next time ;-) I didn't try them all, but it seems safe to say that all audio-only recordings work with mplayer, and only the combined audio/video sessions before thursday have the audio problem. >> I'd appreciate it if you could update the archive website to include >> information on which codec was used for which session. >> It would save futile downloading of earlier sessions made with the >> non-supported codec. > > This change has been made.
