  • Script d’installation automatique de MediaSPIP

    25 avril 2011, par

    Afin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
    Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

  • How to add custom glsl transition file in ffmpeg command ? Getting error like when adding glsl file is "No such filter : 'gltransition"

    22 avril 2022, par Dinesh Reddy

    I was tried with using command

    


    


    ffmpeg -i hiking.mp4 -i video2.mp4 -filter_complex "gltransition=duration=4:offset=1.5:source=crosswarp.glsl" -y outputFile.mp4

    


    


    After running this command getting error like
ERROR MESSAGE

    


    


    No such filter : 'gltransition'

    


    


    I found the way to add transitions using ffmpeg-concat library but in this way can add inbuilt transition names but in my case need to add custom transition glsl file in ffmpeg command

    


    How to overcome from this error in windows system ?

    


  • What does "Error in the pull function" mean while executing ffmpeg command ?

    8 avril 2022, par Alex Rypun

    I'm trying to generate a video from multiple video sources (https urls).

    


    If I use say 8 video sources it works as expected. But if I need say 30 sources, it starts to work as expected, but at some moment a lot of errors appear.

    


    enter image description here

    


    I believe the main one is Error in the pull function..

    


    Such a video-source appears in the output file but not a full requested part (e.g., I set trim=0:5, but ffmpeg generates only 3 seconds).

    


    I tried different videos, different cropped parts, loaded sources to aws s3, but can't identify a "bad case", it's reproduced with different options.

    


    My command looks like this :

    


    ffmpeg -y
-i "https://player.vimeo.com/external/399541658.hd.mp4?s=5432956383527af00bb74b41c120bbb84ff3ac5e&profile_id=175&oauth2_token_id=57447761"
...
-i "https://player.vimeo.com/external/464966383.hd.mp4?s=648aa8277259c499f1d05d6330f9922932c080a6&profile_id=175&oauth2_token_id=57447761"
-i "https://test.com/development/videos/dc3c32cf9a194db1bb52/sources/5q5e3j2h57.mp3"
-filter_complex "[0:v]trim=0:5.64,setpts=PTS-STARTPTS,scale=1920x1080,setdar=16/9[v0];[1:v]trim=0:8,setpts=PTS-STARTPTS,scale=1920x1080,setdar=16/9,loop=0:32767[v1]; ... [10:v]trim=0:13,setpts=PTS-STARTPTS,scale=1920x1080,setdar=16/9[v10];[v0] ... [v10] concat=n=11:v=1 [video];[11:a] atrim=0:99.29 [audio]"
-vsync 2 -map [video] -map [audio] output.mp4


    


    When I downloaded all sources to my local machine and tried to use them in the ffmpeg command it worked fine without errors.

    


    Also, I figured out that it depends on the CPU. When I restricted my CPU the errors appeared earlier. And some commands might produce errors with a restricted CPU but finished successfully with no CPU restriction.

    


    As I understand, for some reason, ffmpeg fails to receive a particular part of a file data, but I believe it should retry to receive lost packages (it's https).

    


    And I don't understand, how it could be related to CPU or sources quantity.

    


    By not understanding the core of evil, I can think about 2 ways (both ugly) :

    


      

    1. to download all sources and generate the final video from local files ;

      2. 


    2. to chunk sources, generate intermediate outputs for each chunk (and save locally), and concatenate them into the final one.

      3. 


    


    Any better suggestions or at least where to seek ?

    


  • 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
