  • Some videos fail to chromecast with error MEDIA_UNKNOWN

    1er juin 2020, par JonasVautherin

    Using mkchromecast to cast local mp4 files, some videos work, and some don't (as in : the screen hangs on the blue chromecast logo, suggesting that the initial connection worked). I can reproduce exactly the issue described here.

    



    So I decided to go one level lower, with pychromecast, and try to see what actually happens when it hangs on the blue logo. I converted two videos to HLS format, and exposed them through an http server. The video that works with mkchromecast also works with my setup, but the one that fails, well... fails on both. With pychromecast, I don't get much more information than :

    



    


    ERROR, code 100 : MEDIA_UNKNOWN.

    


    



    From the Cast documentation, this error means :

    



    


    The media element encountered an unknown error fired from platform. The media element encountered an error that did not indicate it's one of MediaError.MEDIA_ERR_*. This should be rare.

    


    



    It is not rare for me at all, though. I thought that maybe the failing video was in an unsupported format, as described in the documentation. So I tried to compare both videos with the following command :

    



    ffprobe -v quiet -print_format json -show_streams 


    



    Video that works :

    For what I can see, the codecs are the same, and the only difference I can make is in the aspect ratio.

    



    What could be the reason for this "MEDIA_UNKNOWN" error on the chromecast side ? Is there something more I could compare between those two videos ? Could it be that the chromecast fails because of the aspect ratio ?

    


  • How can I overlay a video ontop of background image ?

    19 août 2019, par user11588722

    I have a command which creates waves ontop of a background image :

    ffmpeg -y -i "Assets/Screens/new.png" -i "Temp/video.mp4" -i "Temp/audio.mp3" -filter_complex "[2:a]showwaves=mode=cline:s=255x81:scale=sqrt:colors=0x222222,colorkey=0x000000:0.01:0.1,format=yuva420p[w];[v][w]overlay=240:594,scale=1920:1080[outv]" -map "[outv]" -map 2:a -movflags +faststart -c:v libx264 -c:a aac -preset veryfast -shortest "output.mp4"

    How can I also overlay a 1024x576px video at position 756:252 ?

    I have already included the video file as the second (1:v) input, but I can’t seem to get the filters to play nicely.

    Thanks for any help.

  • FFMPEG, Creating an MPEG-DASH stream with existing inputs

    10 septembre 2019, par kitensei

    I am trying to generating a DASH .mpd file from multiple inputs (2 videos, 1 audio) without any success..

    What I’d like to do it’s simple getting the streams and create an mpd file without any re encoding since I’ve already my sources ready.

    The output seems to work in rxplayer, but I do get a lot of errors (see log below).

    Here are my 3 sources (taken from http://dash-mse-test.appspot.com/media.html) :
