I was trying to decode .rm files with sipr and real (28.8) audio coding using
ffdec_sipr and ffdec_real_288 but the o/p (out.flv) is garbled audio. here
is the complete pipelines i used:


gst-launch filesrc location=28dewdz-ep2.rm ! rmdemux name=demux
demux.audio_00 ! queue ! ffdec_sipr ! audioconvert ! audiorate !
ffaudioresample ! audio/x-raw-int, channels=\(int\)1, width=\(int\)16,
depth=\(int\)16, endianness=\(int\)1234,
rate=\(int\)44100,signed=\(boolean\)true ! lame bitrate=64 ! identity !
ffmux_flv name=mux ! filesink location=/tmp/out.flv


gst-launch filesrc location=bastard.rm ! rmdemux name=demux demux.audio_00 !
queue ! ffdec_real_288 ! audioconvert ! audiorate ! ffaudioresample !
audio/x-raw-int, channels=\(int\)1, width=\(int\)16, depth=\(int\)16,
endianness=\(int\)1234, rate=\(int\)44100,signed=\(boolean\)true ! lame
bitrate=64 ! identity ! ffmux_flv name=mux ! filesink location=/tmp/out.flv

i tried with various other .rm files with audio formats of sipr and real
28.8 and all the the outputs of above pipelines were giving garbled audio.

Is there known issues with these two ffmpeg decoders.
