  • La file d’attente de SPIPmotion

    28 novembre 2010, par

    Une file d’attente stockée dans la base de donnée
    Lors de son installation, SPIPmotion crée une nouvelle table dans la base de donnée intitulée spip_spipmotion_attentes.
    Cette nouvelle table est constituée des champs suivants : id_spipmotion_attente, l’identifiant numérique unique de la tâche à traiter ; id_document, l’identifiant numérique du document original à encoder ; id_objet l’identifiant unique de l’objet auquel le document encodé devra être attaché automatiquement ; objet, le type d’objet auquel (...)

  • Récupération d’informations sur le site maître à l’installation d’une instance

    Utilité
    Sur le site principal, une instance de mutualisation est définie par plusieurs choses : Les données dans la table spip_mutus ; Son logo ; Son auteur principal (id_admin dans la table spip_mutus correspondant à un id_auteur de la table spip_auteurs)qui sera le seul à pouvoir créer définitivement l’instance de mutualisation ;
    Il peut donc être tout à fait judicieux de vouloir récupérer certaines de ces informations afin de compléter l’installation d’une instance pour, par exemple : récupérer le (...)

  • FFmpeg - Extracting video and audio from transport stream file (.ts)

    25 juillet 2015, par Passepartout

    I wish to extract the audio and video of a certain program in a transport stream file (.ts) by specifying its PID without losing quality and using the same codec in the resulting file (the output file is a MPEG).

    Is that even possible with FFmpeg ? If so, how can I do it ?

    So far, I’ve come to this command :

    ffmpeg -i tsfile.ts -vcodec copy -acodec copy -q:v 1 output.mpg

    Edit : Note that the file output.mpg is created. The file contains the video but the audio isn’t attached (no sound). Also, I am unable to specify the program PID to extract.

    Edit 2 : Here’s the output of ffmpeg -i tsfile.ts

  • ffmpeg transcode video with dts-ma to ac3

    12 juin 2015, par John Galt

    I’m trying to take a video that has an h264 video track and a dts-ma audio track and and get out an .m4v file with :

    h264 video track
    DTS-ma audio track
    AC-3 5.1 Audio track

    I’m attempting to just copy the video and the dts-ma audio track and then have it convert the AC-3 audio track

    I’m getting an error Unable to find a suitable output format for 'ac3' from this command :

    ffmpeg -i "input.mkv" -map 0:0 -map 0:1 -map 0:1 -map 0:1 -c:v copy -c:a:0 copy -c:a:1 -acodec ac3 -ac 6 -ab 448k -c:a:2 -acodec ac3 -ac 6 -ab 256 -ar 48000 "output.m4v"

    (this is generated by my C# app)

    this for a different file that has h264 and ac3 already in it works fine :

    ffmpeg -i "input.mkv" -map 0:0 -map 0:1 -c:v copy -c:a:0 copy "output.m4v"

    Obviously it’s not doing a conversion.

    Here’s the full results of the first command :

  • Warning : passthru() has been disabled for security reasons in _audioconverter_scheduler_ffmpeg_helper

    10 décembre 2012, par Meggy

    I am using the audioconverter module with the audiorecorderfield module in Drupal 7 with ffmpeg on my own vps running Aegir and Nginx. The audioconverter module has stopped converting wav files to mp3. Here's the error ;

    Warning: passthru() has been disabled for security reasons in _audioconverter_scheduler_ffmpeg_helper() (line 358 of /mysite/drupal-7.16/sites/all/modules/audioconverter/audioconverter.module).

    And in my logs ;

    MESSAGE: executing: /usr/bin/ffmpeg -i /mysite/drupal-7.16/sites/default/files/1354856044.wav /mysite/drupal-7.16/sites/default/files/1354856044.wav.mp3

    MESSAGE: Audio conversion failed. FFMPEG reported the following output:

    SEVERITY: error

    MESSAGE: converted file is an empty file.

    I can see the wav file is created by the audiorecorderfield module but the audioconverter module is failing on the conversion.

    Here is my ffmpeg info ;
