  • Emballe médias : à quoi cela sert ?

    4 février 2011, par

    Ce plugin vise à gérer des sites de mise en ligne de documents de tous types.
    Il crée des "médias", à savoir : un "média" est un article au sens SPIP créé automatiquement lors du téléversement d’un document qu’il soit audio, vidéo, image ou textuel ; un seul document ne peut être lié à un article dit "média" ;

    Jolie sélection multiple
    Le plugin Chosen permet d’améliorer l’ergonomie des champs de sélection multiple. Voir les deux images suivantes pour comparer.
    Il suffit pour cela d’activer le plugin Chosen (Configuration générale du site > Gestion des plugins), puis de configurer le plugin (Les squelettes > Chosen) en activant l’utilisation de Chosen dans le site public et en spécifiant les éléments de formulaires à améliorer, par exemple select[multiple] pour les listes à sélection multiple (...)

  • Set protocol-level metadata in AVFormatContext any time a packet is read.

    1er août 2014, par Andrew Stone
    Set protocol-level metadata in AVFormatContext any time a packet is read.

    If any option named "metadata" is set inside the context, it is pulled up to
    
the context and then the option is cleared.

  • Why can't I set "aspect ratio" by ffmpeg -aspect ? [on hold]

    7 août 2014, par yasi

    I want to generate an h264 (avc) file by a jpg file. I generated it by command :

    • ffmpeg -f image2 -i img%d.jpg -vcodec libx264 sample.h264
    • mv avatar.h264 sample-320.avc

    the img%d.jpg is 0.jpg, 1.jpg, 2.jpg ... 24.jpg, all of which is the same, resolution is 320x180

    When sample.avc is generated, I checked information of it by ESEyE, it’s like below.
    enter image description here

    As you can see, the resolution is correct, but aspect ratio is weird since original jpg sequence is 320x180, whose aspect ratio is 16:9. So, I tried to keep 16:9 by the command below

    • ffmpeg -r 25 -f image2 -i img%d.jpg -vcodec libx264 -profile:v baseline -level:v 1.1 -aspect "16:9" sample.h264

    However, it doesn’t work, the generated avc aspect ratio is still 5x3.

    How can I keep aspect ratio of 16:9 ?

    P.S.
    I guess h264 miminal block is 16x16, and avc width could be padded as 192 (16 * 12), so aspect ratio is 320:192 = 5:3.

  • ffmpeg HLS creation and segmentation results in "cannot decode" on iPad

    5 mai 2014, par jt_dylan

    I have the following code that plays on Mac Safari :

        
    
       
    
       
    
       
    

    
    <video controls="controls" width="480" height="270">
    
    
    
    <source src="http://d1ckv7o9k6o3x9.cloudfront.net/d54cfa01-eff2-4e86-946e-dc8b2ee4a7e8/media/  hls/MVI_5927.m3u8">
    
    </source></video>

    The url can be cut/pasted into the browser and works also but neither this code nor the url works in Windows Safari or iPad. Specifically on iPad I receive a cannot decode error. On Mac I have Quicktime installed so I tried that on Windows with no luck. The link that can be play on Mac is below.

    http://d1ckv7o9k6o3x9.cloudfront.net/d54cfa01-eff2-4e86-946e-dc8b2ee4a7e8/media/hls/MVI_5927.m3u8

    Browser Versions of software :
    Mac Safari : Version 7.0.3 (9537.75.14) (works)
    Windows Safari : Version 5.1.7 (7534.7.2) (doesn’t work - blank screen)
    iPad Safari : ios Version 7.1.1 (doesn’t work - cannot decode)

    Here is how I’m creating my mp4 (lgpl)
    I’m creating an mp4 with this command :
    ffmpeg -i input.mov c:v mpeg4 q:v 1 test.mp4

    I’m creating the hls using ffmpeg lpgl with this command :

    ffmpegcmd -re -y -i test.mp4 -map 0 -f segment -segment_list test.m3u8 -segment_list_flags +live -segment_time 1 -segment_list_type m3u8 test%05d.ts 2>&amp;1

    Now this works in Mac Safari with Quicktime installed but results in "cannot decode" if I try the url from ipad Safari.

    I then tried with libx264 to create the mp4 as h.264 with aac and then copy to mpeg2 container as follows :

    ffmpeg -i test.mov  -c:v libx264 -c:a libfdk_aac -preset slower -b:a 240k test.slower.mp4
    
ffmpeg -i test.slower.mp4 -vcodec copy -f mpegts -bsf h264_mp4toannexb test.slower.ts
    
ffmpeg -re -y -i test.slower.ts -map 0 -f segment -segment_list test.slower.m3u8 -segment_list_flags +live -segment_time 1 -segment_list_type m3u8 test.slower.%05d.ts

    This still produces the same results. Any idea what is wrong here ?

    Any help is much appreciated.

    Regards,
    jt_dylan

    Output from libx264 commands below :

    ffmpeg -i test.mov  -c:v libx264 -c:a libfdk_aac -preset slower -b:a 240k test.slower.mp4
