  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • Les tâches Cron régulières de la ferme

    1er décembre 2010, par

    La gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
    Le super Cron (gestion_mutu_super_cron)
    Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...)

  • FFmpeg HLS Live Stream Stuck with iOS 11

    1er novembre 2017, par Lamorun

    I’ve exp with FFmpeg but i recent problem with iOS 11 (Recent release for Apple)

    I used FFmpeg for stream HLS Live Stream for only iPhone and iPad in closed app for online courses. My problem is the next :

    I used this code for HLS Live Stream :

    ffmpeg -i "Input" -preset fast -c:v libx264 -c:a aac -ac 1 -strict -2 -crf 18 -profile:v baseline -maxrate 1000k -bufsize 1835k -pix_fmt yuv420p -b:a 64k -flags -global_header -hls_time 20 -hls_list_size 6 -hls_wrap 10 -start_number 1 /m3u8/test.m3u8

    This work perfect in iOS 8, 9 and 10 devices. But with new version iOS 11, video is stuck after about 30 to 40 seconds, as seen in the image :

    ios11stuck

    I have searched for hours and hours. I have done many tests, but I can not get it out, since it works perfectly with iOS 8,9 and 10 (test in somes devices, even working perfectly on a device with iOS 10, update to iOS 11, and stop working immediately, downgrade to iOS 10 and work again)

    I hope someone can help me out, thank you and greetings to all

  • Usage FFmpeg command to capture video from Apple device camera and to get 3 outputs with different resolutions (UHD, FHD, HD)

    12 décembre 2019, par Levon Gharibyan

    I use mobile-FFmpeg to execute FFmpeg commands (https://github.com/tanersener/mobile-ffmpeg).

    I am using AVFoundation, and trying to get 3 output files (3840x2160, 1920x1080 and 1280x720) from device camera.
    Here is the command :

    -f videotoolbox -f avfoundation -video_size 3840x2160 -r 30 -pixel_format nv12 -i "0:0"  -c:v h264_videotoolbox -b:v 8M -maxrate 8M -s 3840x2160 output1/path -c:v h264_videotoolbox -b:v 8M -maxrate 8M -s 1920x1080 output2/path -c:v h264_videotoolbox -b:v 8M -maxrate 8M -s 1280x720 output3/path

    But the encoding process is very slow (0.3x-0.4x speed) with that command and as a result, I can’t record realtime 30fps outputs. What am I doing wrong ? All my tests were done on the iPhone 7.

  • FFMpeg - Segment audio to chunks

    8 mars 2015, par fr3sh

    I have tried this example in order to segment a given video file using ffmpeg into an m3u8 file and smaller chunks (.ts files). This actually worked great. Is it possible to do practically the same thing with audio input ?
    This was my most promising approach so far (capturing live audio on Windows OS) :

    ffmpeg -f dshow -i audio="<name of="of" input="input" device="device">" -acodec libmp3lame -ab 64000 | segmenter - 10 stream stream.m3u8 http:///stream/stream/ 5 1
    
</name>

    But this returns this error :

    At least one output file must be specified.
    
Could not open input file, make sure it is an mpegts file: -1

    I really would not know how to convert the live audio stream to an mpegts file.
    Could anyone please give me a hint ?

    Thanks a lot
