  • Multi-language broadcasting title metadata for Audio & subtitle is not working

    28 septembre 2022, par Fariduzzaman Xenar

    I have a (.mp4) video file that contains 1 video track, 2 audio tracks & 2 subtitles. I already used different titles for audio tracks on encoding, but it's not working on any web player like JWPlayer, or Flussonic, where Multi-language broadcasting is supported. It shows eng a1, hin a2 for audio | eng t1, ben t2 for subtitle

    


    I want to show it like this English, Hindi for audio | English, Bangla for Subtitle

  • ffmpeg rtsp stream to YouTube livestream not doing anything

    29 mai 2018, par felixosth

    I’m using C# to initiate ffmpeg. I’ve a onvif bridge server for a CCTV VMS and I’m building a application to enable the user to livestream any CCTV camera to YouTube.

    The rtsp stream to the camera looks like this :

    rtsp ://onvif:bridge@localhost:554/live/xxxxx-xxxguidtocameraxxx-xxxxx

    I’m new to ffmpeg and I’m using this arg :

    -f lavfi -i anullsrc -rtsp_transport udp -i camerastreamurl -tune zerolatency -vcodec libx264 -pix_fmt + -c:v copy -c:a aac -strict experimental -f flv rtmp ://x.rtmp.youtube.com/live2/streamkey -loglevel debug

    It seems like ffmpeg isn’t finding the camera stream, only the fake audio one. It just freezes.

    This is the result of the debug log :

  • wrong ffmpeg version for xuggler

    13 décembre 2011, par kerel

    I am trying to get Xuggle working on Ubuntu.
    This is however my first time using a Unix system.

    After installing Xuggle and correcting the PATH files I tried some very simple code from tutorials at the xuggle website. But once I attempt to debug my code, it stops and eclipse says

    Suspended (exeption IllegalArgumentException)

    and refers to line 488 of MediaReader.readPacket()

    After searching possible explanations I found that my FFMPEG version was not the version Xuggle needs. When I test my FFMPEG version from command line with
    $ ffmpeg /invalid/file/ it displays --extra-version='4:0.7.2-1ubuntu1' but according to the xuggle site the --extra-version= should include the word "xuggle". Following their installation procedures does not change anything.

    I downloaded the source code from SVN, which includes a ffmpeg folder. I assume this is the ffmpeg version I need. I have no clue however what to do with this folder.

    question is : how do I get my ffmpeg version to the xuggle compatible ffmpeg version ?
