[FFmpeg-user] Streaming audio input in a lossless format

[Alex Becerra]

Hello,

I've tried the following commands

1.- "ffmpeg -f alsa -i hw:0 -acodec libmp3lame -ar 12000 -ac 1 -f rtp rtp://
234.5.5.5:1234"
--> ffplay and VLC reproduce this

2.- "ffmpeg -f alsa -i hw:0 -acodec pcm_s16le -f rtp rtp://234.5.5.5:1234"
--> ffplay and VLC answer this "[rtp @ 02930420] Unable to receive RTP
payload type 97 without an SDP file describing it"

How can I send raw data?
How can I do it using udp?
Is FLAC supported for streaming?

Thanks.

Regards,
Alex.
