  • VLC command line : RTSP to mp4 file (video + audio)

    8 février 2016, par Dmitriy Gerashenko

    Win 7 x64.

    When I watch this link in VLC player all is fine :

    rtsp ://184.72.239.149/vod/mp4:BigBuckBunny_175k.mov

    When I try to capture link to file and to display :

    • There is video without sound on display.
    • Created file is not playable.

    Command :

    vlc.exe -vvv "rtsp://184.72.239.149/vod/mp4:BigBuckBunny_175k.mov" --sout="#transcode{venc=ffmpeg,vcodec=mp4v,vfilter=canvas{width=800,height=600},aenc=ffmpeg{strict=-2},acodec=mp4a}:duplicate{dst=display,dst=standard{access=file,mux=mp4,dst=video.mp4}"

    There are some errors in log, for example : MPEG4GenericRTPSource Warning: Unknown or unsupported "mode": AAC-hbr. Is it cause of my problems ? How to solve my issue ?

    Complete log (from VLCJ) :

    I am Using X server for the virtual screen on Google Colab and capturing that screen with ffmpeg to record it and live stream it to twitch. (for the reinforcement learning project)

    


    


    The above process was completely working till my last use of my Colab notebook (on mid-January 2021), but now (on 19th February 2021) I am using the same notebook and the streaming code has stopped working.

    


    


    I am adding config and log file data below. (I have never seen these files before because it was working, now it's not so I don't have any idea what wrong)

    


    The config file stored at /etc/X11/xorg.conf have the following data :

    I am using this github repo to setup the video-streamer

    


    If anyone wants the colab notebook for the example then I will add it over here.

    


    For this problem I am really not sure where to file an issue for this so that's why I am writing this here.

    


  • ffmpeg error while converting to mp4 Error while opening encoder for output stream #0.0

    20 mars 2016, par Josh

    I am trying to convert various file types to mp4 to be displayed using ffmpeg, but i keep getting the error :

    Error while opening encoder for output stream #0.0 - maybe incorrect parameters such as bit_rate, rate, width or height

    Another piece that looks important is :

    [libx264 @ 0x93caef0] broken ffmpeg default settings detected

    [libx264 @ 0x93caef0] use an encoding preset (e.g. -vpre medium)

    [libx264 @ 0x93caef0] preset usage : -vpre -vpre

    [libx264 @ 0x93caef0] speed presets are listed in x264 —help

    [libx264 @ 0x93caef0] profile is optional ; x264 defaults to high

    The latest code I am running is :

    ffmpeg -i source -s 320x240 -r 30000/1001 -b 200k -bt 240k -vcodec libx264 -coder 0 -bf 0 -refs 1 -flags2 -wpred-dct8x8 -level 30 -maxrate 10M -bufsize 10M -acodec libfaac -ac 2 -ar 48000 -ab 192k destination

    I have seen a few other people with this issue, but their fixes didn’t work for some reason.

    In case it matters : ultimately this will be used in php, though I am trying to get it working first via putty

    EDIT: : Here is the full thing as requested(using a wmv, have tested wmv and flv) :

         ~ >> ffmpeg -i path.wmv -s 320x240 -r 30000/1001 -b 200k -r 29.97 -bt 240k -vcodec libx264 -coder 0 -bf 0 -refs 1 -flags2 -wpred-dct8x8 -level 30 -maxrate 10M -bufsize 10M -acodec libfaac -ac 2 -ar 48000 -ab 192k path.mp4
