  • Use audio stream overs ssh with ffmpeg on web page

    12 février 2020, par Mauricio

    I need to broadcast the audio stream (WiFi camera at my home) on the website hosted on a VPS.

    Here is the command executed from my home :

    ffmpeg -i "rtsp://172.16.0.201:554/user=admin&password=root&channel=1&stream=1.sdp" -bufsize 24k -vn -acodec copy -f mpegts - | ssh -p 22222 root@mydomain.org 'ffmpeg -i - -vn -acodec libvorbis -ac 1 -ar 8000 -ab 64k -f mpegts "rtsp://127.0.0.1:53350/live.sdp"'

    It seems to work because I get

  • FFMPEG profile-level-id size is invalid

    18 février 2020, par Mulham Aryan

    I’m trying to record a RTSP streaming from JVC KY-PZ 100.
    So for that i’m using ffmpeg with some parameters like segmentation, hls, ts, m3u8 etc ...
    i’m always getting an error The profile-level-id field size is invalid (41) and Error parsing AU headers

    This is the output of FFPROBE to debug the RTSP
