Hello,

There's a TV channel that I watch using IPTV in VLC, it works fine, I have both audio and video, however, if I decide to record it in VLC, when I open the video file still in VLC, I have no sound. This is what I use to record the stream:

Code: Select all

vlc "rtsp://mafreebox.freebox.fr/fbxtv_pub/stream?namespace=1&service=204&flavour=sd" :run-time=5 --sout test2.mpg vlc://quit

How could I solve this problem?
Thanks,

Maybe the specified file format (MPEG PS) does not support the received audio codec.

Thank you. How could I troubleshoot it ? Is there a way to find a proper codec?

Here's more info:

Codec: mp4a
AAC Extension: SBR

Do you know what container I should use?
Thanks again,

I found out that if I save using .mp4 container, I have sound but the video if cut in half with a thick black strip on top

Is there a way to change this command in order to have the original video from the MPEG container, the audio of the MP4 container and saving everything using the MPEG container?

Code: Select all

vlc "rtsp://mafreebox.freebox.fr/fbxtv_pub/stream?namespace=1&service=210&flavour=ld" :run-time=5 --sout test.mpg

Thanks again,

This seems to be the options to use but I don't see any change using some of them or not...

It seems that I'm not the only one with this issue...
