  • Having issues with kdenlive screen capture mode

    5 décembre 2018, par brianH

    Am running new repository install of kdenlive on ubuntu 18.04 after having similar problem on 16.04 but the problem persists "failed to start the capture application" when i start in screen capture mode. This problem was also present when I used kdenlive appImages.
    The current kdenlive version is 17.12.3 and i’ve tried changing kdenlive config settings, switching to default settings etc. also cleaned the /.cache/kdenlive file ..

    Ironically, when I use gdb kdenlive then run, the capture device works. Although then there is a separate issue of playing the video with the project monitor.

    On the previous 16.04 build had an addition log message that libvorbis was not recognized when the capture application failed.

    I had purged, autoremove packages and Resinstalled, also reinstalled ffmpeg and the installed libvorbis packages.
    Running ffmpeg gives :

  • FFMPEG : Youtube streaming quality and speed issues

    25 février 2020, par Alex Paramonov

    I am trying to make a reliable stream from my Icecast/Shoutcast servers to Youtube live. The command that I use is :

    ffmpeg -v verbose -framerate 30 -loop 1 -i /var/image.jpg -re -i http://127.0.0.1:4700/radio -c:v libx264 -preset ultrafast -b:v 2250k -maxrate 6000k -bufsize 6000k -c:a copy -ab 128k -s 1920x1080 -framerate 30 -g 60 -keyint_min 60 -f flv  rtmp://a.rtmp.youtube.com/live2/xxx

    As you can see I am using recommended bitrate for Youtube, insert keyframes every 2 seconds and streaming at 30 frames per second.
    The stream is working but after running for some time two thing are happening :

    1. FFMPEG speed falls from 1x to something like 0.998x
    2. Youtube starts complaining that video stream speed is slow, markes the quality as bad and sometimes video starts buffering.

    Why is this happening ? CPU load is normal, connectivity is ok (the stream is running on a 1Gg/s dedicated server).

    Since in my example above I am streaming a single image as a logo of the stream I also tried to generate a short 30 seconds video with that image and broadcast that video instead of an image, but that did not help as well.

    The command I used for conversion :

    ffmpeg -framerate 30 -loop 1 -i /var/image.jpg -c:v libx264 -preset ultrafast -tune stillimage  -b:v 2250k -minrate 2250k -maxrate 6000k -bufsize 6000k -framerate 30 -g 60 -keyint_min 60 -t 30 out4.mp4

    And broadcast with

    ffmpeg -stream_loop -1 -i out4.mp4  -re -i http://127.0.0.1:4700/radio -c:v copy -c:a copy  -framerate 30 -g 60 -keyint_min 60 -f flv  rtmp://a.rtmp.youtube.com/live2/xxx

    ffmpeg version is 4.1.1

  • How to concatenate multiple mp4 files which are having their own audio without getting audio sync issues ?

    27 septembre 2016, par SharanTheja

    I am having multiple mp4 files with audio in it. I want to merge all the files to get a single mp4 file. Even though I have seen many questions like this . Nothing worked out for me without audio syncing issue.
