    Le lecteur ne fonctionne pas sur Internet Explorer
    Sur Internet Explorer (8 et 7 au moins), le plugin utilise le lecteur Flash flowplayer pour lire vidéos et son. Si le lecteur ne semble pas fonctionner, cela peut venir de la configuration du mod_deflate d’Apache.

  • Is it safe to ignore the error "Invalid UTF-8 in decoded subtitles text ; maybe missing -sub_charenc option Error while decoding stream" ?

    30 avril 2022, par Clogged-artery

    I was encoding a video with subtitles and I got the error, "Invalid UTF-8 in decoded subtitles text ; maybe missing -sub_charenc option. Error while decoding stream" but the video encoded anyway. What are the consequences of ignoring this error ? A google search showed a result of one guy saying it skips that sub so the resulting video will have missing subs. Can someone confirm this ?

    


    I know how to fix it but I have already converted 50+ videos with subtitles and I'm fairly certain that a few of them had this error. I just want someone to tell me that it's okay to ignore so I don't have to watch 200 hours of videos.

    


    Solution for fixing subtitle errors :

    


    Create a batch file and edit with the following :

    


    for %%a in ("*.srt") do ffmpeg -v 9 -loglevel 99 -sub_charenc CP1252 -i "%%a" "newfiles\%%~na.srt"
pause


    


  • Gstreamer, x264enc "Redistribute latency..." error

    20 août 2021, par Jason

    I'm trying to setup a video pipeline with very limited bandwidth. I was able to do it with two raspberry pis using the below lines. The first is for the camera pi and the second is to watch stream :

    


    gst-launch-1.0 rpicamsrc preview=false !  'video/x-h264, width=800, height=600, framerate=30/1' ! h264parse ! rtph264pay config-interval=1 pt=96 ! gdppay ! udpsink host=YOUR_PC_IP port=5000
gst-launch-1.0 udpsrc port=5000 ! gdpdepay ! rtph264depay ! h264parse ! avdec_h264 ! autovideosink sync=false


    


    It works but I go over my bandwidth limit if there is movement. I'm not sure if there is a way to limit bandwidth by setting a parameter here :

    


    'video/x-h264, width=800, height=600, framerate=30/1'


    


    From what I can find online, I have to use something like x264enc. I've followed tutorials but I can't get x264enc to work. it always outputs "Redistribute latency..." on both machines when run and it stays there.

    


    I've tried using x264enc like follows :

    


    gst-launch-1.0 rpicamsrc preview=false !  'video/x-raw, width=800, height=600, framerate=30/1' ! x264enc ! h264parse ! rtph264pay config-interval=1 pt=96 ! gdppay ! udpsink host=YOUR_PC_IP port=5000
gst-launch-1.0 rpicamsrc preview=false !  'video/x-raw, width=800, height=600, framerate=30/1' ! x264enc tune=zerolatency ! h264parse ! rtph264pay config-interval=1 pt=96 ! gdppay ! udpsink host=YOUR_PC_IP port=5000
gst-launch-1.0 rpicamsrc preview=false ! x264enc ! h264parse ! rtph264pay config-interval=1 pt=96 ! gdppay ! udpsink host=YOUR_PC_IP port=5000
gst-launch-1.0 rpicamsrc preview=false ! x264enc tune=zerolatency ! h264parse ! rtph264pay config-interval=1 pt=96 ! gdppay ! udpsink host=YOUR_PC_IP port=5000


    


    Based on tutorials, I would think some of those should work. Other threads say that tune=zerolatency fixes my problem. At least the ones with same output of "Redistribute latency..." I don't know what I'm doing wrong.

    


    Any help would be appreciated. Thanks !

    


  • HTML mp4 Streaming / How can I automatically move the "atom moov" to the beginning of the file ?

    29 octobre 2020, par Einkornwolf

    so I am currently building a Website for School and implemented an Upload-System. Now I want People to be able to watch uploaded Videos. Currently if you try to watch a Video, lets say test.mp4 it takes over a minute to load. I know that using : ffmpeg -i inputvideo.mp4 -movflags faststart -acodec copy -vcodec copy outputvideo.mp4 moves the atom moov to the beginning of the file. And when I manually convert the mp4 using the previous command the file starts playing instantly. But now my problem is, that I don't want to convert each file manually. Is there another way of playing user-uploaded Videos instantly ? Thanks for your help in advance.

    


    I am using this Code, but it has nothing to do with the streaming itself I guess :

    


      <source src="Clap.mp4" type="video/mp4">&#xA;Your browser does not support the video tag. &#xA;&#xA;</source>

    &#xA;

    I also tried to use a js library :

    &#xA;

      &#xA;&#xA;  &#xA;  <code class="echappe-js">&lt;script src=&quot;https://vjs.zencdn.net/ie8/1.1.2/videojs-ie8.min.js&quot;&gt;&lt;/script&gt;&#xA;&#xA;&#xA;&#xA;  &#xA;    &#xA;    &#xA;    

    &#xA; To view this video please enable JavaScript, and consider upgrading to a&#xA; web browser that&#xA; supports HTML5 video&#xA;

    &#xA; &#xA;&#xA; &lt;script src=&quot;https://vjs.zencdn.net/7.8.4/video.js&quot;&gt;&lt;/script&gt;&#xA;&#xA;

    &#xA;

    In both cases I want to play Clap.mp4
