I want grab audio from my sdr-device and convert it to h264.
I use rtl_fm, check any options, but I can't listen any good sound :(
For example: rtl_fm -f 10000000 -s 44100 - | mplayer - -quiet -rawaudio rate=8000:bitrate=44100 -demuxer rawaudio
My apologies for breaking threading on this message - just signed up to the ML today.
I can't help you without a lot more information. Is this a narrow band or a wide band FM signal? Do you want to save the audio to a file or a network stream? What operating system are you using? Why are you trying to compress an audio stream with a video codec?

Hi, Kyle!
Thank you for reply. I tested and developed on my Mac (Darwin), but I want put this solution on my dedicated server Debian Linux. I need broadcast UHF 430–440 MHz (ham – 70 cm band) to internet. Only audio stream.
Something like this: DVB-T tuner -> Linux -> sdr grabber -> mencoder | ffmpeg | vlc | etc.. -> icecast (mp3, acc, ogg, etc.)
May be you know any another way to resolve my goal?
And another my idea create something like using websdr.org software, but main developer does not give the source code to anyone.
