Playback of video/stream (HLS): MediaEvent: PIPELINE_ERROR with audio only



  • Hello,

    I have an issue with video-stream playback in Qt`s WebEngine.

    The stream I am trying to use is placed onto a webpage. It plays fine in a WebEngine while it does not contain any audio.
    If I enable audio for the stream, the video area stays blank and the video is never played (looks like a crash).

    In other normal browsers (Firefox, Chrome, etc.) on the same system the same webpage where the stream is placed in plays fine in all cases so I can only reproduce this in WebEngine.

    I have tried it with Qts Quickbrowser example too, same problems there.

    What I got from debugs output is this:

    [0207/144405:ERROR:render_media_log.cc(20)] MediaEvent: PIPELINE_ERROR pipeline:decode error
    

    The stream comes from a local Nginx Rtmp testing Server (URL - only available locally at the moment, sorry):
    http://192.168.1.108:8080/hls/test.m3u8

    For playback of the HLS stream within my webpage I am using the following library:
    https://github.com/dailymotion/hls.js

    If I open the stream in VLC it also works fine.

    I have also tried different Qt versions, still no luck.

    How can I furhter debug what causes that problem (I guess this may be a "real" decoding problem?) ?

    If you need furhter details please ask me !
