  • Grabbing rtsp/rtp stream with libavformat

    19 janvier 2012, par T0ha

    world.
    I'm trying to grab rtsp mjpeg stream from IP-camera (realtime) as described in http://www.inb.uni-luebeck.de/ boehme/using_libavcodec.html, but ported to newer version.
    It works well with mpeg file (loading it full as one AVPacket), but working with stream, avcodec_decode_video2 returns -1 (error). AVPacket in this case is a part of a frame.

    How can I fix this ?

  • Dumped video stream often not readable in VLC

    30 janvier 2017, par user7490232

    I have two IP Cameras, and I’m regularly collecting the dumped video stream in a file. Every 30 minutes I kill down the running processes, and restart dumping, using the "mplayer" command in background to generate a .mp4 file.

    Basically I’m running something like this :

    killall mplayer
    
mplayer -dumpstream rtsp://cam01:554/video.mp4 -dumpfile cam01.mp4 & bg
    
mplayer -dumpstream rtsp://cam02:554/video.mp4 -dumpfile cam02.mp4 & bg

    Then I store all the resulting .mp4 files for future checks.

    Now there is the problem : many files are perfectly readable (using VLC) and many files aren’t (I’m just able to open "unreadable" files using the "ffplay" utility).

    However, as I’m using a VLC app in a smart TV to open them, I’d like to be able to open all files in VLC. Could you please give me some advice ?

  • ffmpeg Unrecognized option '—enable-libopus'

    9 juillet 2021, par Irith

    I'm running ffmpeg from a windows 10 machine.

    


    My goal is to trim silence from the beginning to the end of a track (this works just fine) and compress using opus.

    


    I am new in the "audio elaboration" world so maybe I'm not understanding this properly...but the main issue here is that ffmpeg doesn't recognize —enable-libopus although it's clearly in the options (see attachment).

    


    Can anyone help please ?
