  • VLC Ubuntu : Problems converting rstp streaming into http streaming

    16 janvier 2019, par Gorka Sanz Monllor

    I am trying to convert in a Linux Ubuntu Machine a rstp stream into a http stream, so I execute the following comand :

    vlc -vvv -Idummy rtsp://**************************************transportmode=unicast --sout #transcode{vcodec=MJPG,venc=ffmpeg{strict=1}}:standard{access=http{mime=multipart/x-mixed-replace;boundary=--7b3cc56e5f51db803f790dad720ed50a},mux=mpjpeg,dst=:8080/} --run-time= 300

    vlc ://quit

    and it doesn’t work. The output is the following :

    root@f139da580fd9:/# vlc -vvv -Idummy rtsp://*********Streaming/Channels/101?transportmode=unicast --sout #transcode{vcodec=MJPG,venc=ffmpeg{strict=1}}:standard{access=ht                  tp{mime=multipart/x-mixed-replace;boundary=--7b3cc56e5f51db803f790dad720ed50a},mux=mpjpeg,dst=:8080/} --run-time= 300 vlc://quit

  • Streaming Webcam using VLC +FFmpeg over lan - Error : cannot pre fill buffer

    23 juin 2016, par user1804015

    I’ve been trying to stream my webcam over lan using VLC and FFmpeg

    but I end up with the error "Main stream error : cannot pre fill buffer"

    Here is the code I’ve tried

    ffmpeg -f x11grab -s 1680x1050 -r 30 -i :0.0+0,0 -vf "movie=/dev/video0:f=video4linux2, scale=180:-1, setpts=PTS-STARTPTS [movie]; [in] setpts=PTS-STARTPTS, [movie] overlay=main_w-overlay_w-10:main_h-overlay_h-10 [out]" -f alsa -ac 2 -i pulse -vcodec libx264 -preset ultrafast -s 1280x768 -acodec libfaac -threads 0 -f mpegts - | vlc -I dummy - --sout '#std{access=http,mux=ts,dst=thalha:3030}'

    And this is the output
