  • ffmpeg to YouTube with tee mux giving resolution warning (65535x65535), which is not optimal

    25 juillet 2022, par kuldeep chopra

    I am streaming to YouTube and Facebook using ffmpeg , also writing data into disk (recording).

    


    it's working fine on Facebook and recording but on YouTube it's giving warning that is

    


    Please check the video resolution. The current resolution is (65535x65535), which is not optimal.

    


    and output on YouTube is also 1:1 aspect ratio due to the above resolution.

    


    I am using tee mux in ffmpeg Command.

    


    ffmpeg -f dshow -framerate 30 -i video="Integrated Webcam":audio="Microphone Array (Intel® Smart Sound Technology (Intel® SST))" -s 1920x1080 -c:v libx264 -r 30 -preset ultrafast -tune zerolatency -crf 28 -pix_fmt yuv420p -c:a aac -strict -2 -ac 2 -b:a 128k -t 4 -map 0 -f tee "[f=ismv]pipe:1 | [f=flv]rtmps ://youtube | [f=flv]facebook"

    


  • 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 ?
