Question: recording and live at the same time

[stranger2904]

Hello

Is it possible to setup a recording on a receiver instance ?
or record and transmit at the same time from the source ?
I've tried to use a combination of hd-rum-transcoder and ffmpeg but with no luck...

You are trying to record the output stream or the input signal?

[stranger2904]

Output stream. My goal is to record locally high bitrate/high quality stream while send to receive side low-bitrate/low-res signal. hd-rum-transcoder allows me to split/downconvert signal but now I need to figure out how to make a recording.

So what you are really trying to do is this:

         /-------low res stream -----------> to internet
INPUT -- 
         \------- high quality record file

[stranger2904]

yes, you are correct, this is what I'm trying to achieve

Hi, both should be possible

Is it possible to setup a recording on a receiver instance ?

uv ... -d dump[:dir]

(here there may not be another display, however)

or record and transmit at the same time from the source ?

uv ... --export[=dir] <recv>

In both cases you'll get individual frames in the output directory. But it may not be a problem to post-process them, eg. for H.264 frames, simple concatenation gives playable/convertible stream, see also here.
