  • 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.

  • video after ffmpeg command conversion is not playing on windows

    10 décembre 2015, par Hemant Kumar

    I am stuck at a very weird and complex problem, hoping if anyone know the solution :

    I am converting user uploaded video using ffmpeg command on server and it was working fine as well. Today I found that if a video is recorded by a webcam from windows, is playing well in linux as well as on windows where as if user is creating a video by webcam from linux, is playing only on linux (any browser). On window it’s screen either show loading icon or black screen while audio is working fine.

    I am using following codec :

    ['-strict', '-2', '-preset slow', '-maxrate 500k', '-bufsize 1000k', vfOption, '-threads 0', '-ab 64k', '-movflags faststart','-vf scale=-1:480', '-metadata:s:v:0 rotate=0', '-vcodec libx264']

    I work on linux and using html5 player on my website. I am converting video in mp4 format.

    Input :

    ffmpeg -i /<server path="path">/stream_FE2AF05B-E630-1F7B-390B-37325B31B362.flv -strict -2 -vcodec libx264 -preset slow -vb 500k -maxrate 500k -bufsize 1000k -vf 'scale=-1:480 ' -threads 0 -ab 64k -s 640x480 -movflags faststart -metadata:s:v:0 rotate=0 /<server path="path">/testing.mp4
    
</server></server>

  • Issue when combining 2 video files [after matching the specs]

    6 décembre 2015, par Rune

    Basically I got a .mp4 and a .flv file which I want to concatenate (the .mp4 should be the intro).

    So after having asked a previous question regarding this I went ahead and converted the intro video to an .flv with matching specifications of the second video.

    First I got the specifications of the second (.flv) video using ffprobe. This was the output :

    It starts off playing the intro just fine.
    However, when the intro is finished the video freezes while the sound of the actual video continues for the entire duration of the video.

    Thus in conclusion what is lacking is the video of the second vid (the audio is fine).

    I’m new at using ffmpeg but I’ve tried my best to solve this, which is why I’m asking for your help.

    I’d certainly appreciate if someone could help me out.

  • FFMPEG Converted Video Not Working In HTML5

    Converted Avi to Mp4 using FFMPEG, Converted video not working in html
    5

    I have a section in my web page where user can upload any types of videos of any format , currently only restricted to .mp4 and .avi. After successfull upload i have displayed the same video to the user. I have bind the path in HTML5 video so that the user can view the content he/she has uploded. Video with extension .mp4 no doubt are working properly as HTML5 support them. Tricky part is it don’t support Avi files. Now here what the problem has arised. In order to display avi videos i have used FFMPEG to convert videos with extension .avi to .mp4. With lots of googling and reading forum, i have succesfully converted avi videos to mp4 . Here’s what i have used :-

    1. ffmpeg -i input.avi -acodec libfaac -b:a 128k -vcodec mpeg4 -b:v 1200k -flags +aic+mv4 output.mp4

    2. ffmpeg -i input.avi -c:v libx264 -b:a 128k -vcodec mpeg4 -b:v 1200k -flags +aic+mv4 output.mp4

    Above two are working perfectly, they have succesfully converted the video. But when i run them on browser in HTML5 and in new tab (Flash Player Plugin Installed), HTML5 doesn’t play it and flash player return an error message "Video can’t be played because the file is corrupt". But when i played them on KMplayer and in Window media player they are running perfectly.

    I have been to various threads in stackoverflow related to convert avi to mp4 and here i found following in one of the forum. where one of user has accepted this a correct answer but it ain’t worked out for me.

    1. ffmpeg -y -i sample.avi -b:v 1500k -vcodec libx264 -vpre slow -vpre baseline -g 30 sample.mp4

    Above argument returned me following error "File for preset ’slow’ not found".

    Following my futher searches i came across this thread ffmpeg convert mov file to mp4 for HTML5 video tag IE9. Here following argument worked perfectly and it able to convert video in such way that it is playble on browser.

    1. ffmpeg -y -i input.avi -vcodec libx264 -vprofile high -preset slow -b:v 500k -maxrate 500k -bufsize 1000k -vf scale=-1:480 -threads 0 -acodec libvo_aacenc -b:a 128k -pix_fmt yuv420p output.mp4.

    Problem i faced here was video is converted to 420p reso which quality is noty upto mark. Smaller resolution videos are been enlarged and seems pixelated

    Thus, i had to finally put up a question. I will be very obliged if someone can give a solution for above problem. I need to convert an avi video to mp4 supported by HTML5 video tag. It should able to play it on browser and during conversion of video it should maintain original audio and video quality plus resolution.

    Thanks
