  • Le plugin : Podcasts.

    14 juillet 2010, par

    Le problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
    Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;
    Types de fichiers supportés dans les flux
    Le format d’Apple n’autorise que les formats suivants dans ses flux : .mp3 audio/mpeg .m4a audio/x-m4a .mp4 (...)

  • How to handle queueing of video encoding during multiple video uploads ?

    6 mars 2016, par Yash Desai

    I am working on developing a video streaming site where users can upload videos to the site (multiple videos at once using the uploadify jquery plugin).

    Now, I am faced with the question of encoding the videos to FLV for streaming them online.

    When should the video encoding process take place ? Should it take place immediately after uploads have finished (i.e redirect the user to upload success page, and then start encoding in the background using exec command for ffmpeg ?) However, using this approach, how do i determine if the encoding has finished successfully ? What if users upload a corrupt video and ffmpeg fails to encode it ? How do i handle this in PHP ?

    How do i queue encoding of videos since multiple users can upload videos at the same ? Does FFMpeg has its own encoding queue ?

    I also read about gearman and message queueing options such as redis and AMQP in another related SO thread. Are these one of the potential solutions ?

    I would really appreciate if someone could give answers to my questions.

  • Find if video file has audio present in it [duplicate]

    30 juillet 2018, par Kartos

    This question already has an answer here :

    I’m trying to figure out if a video has audio present in it so as to extract the mp3 using ffmpeg. When the video contains no audio channels, ffmpeg creates an empty mp3 file which I’m using to figure out if audio was present in the video in the first place. I’m sure there is a better way to identify if audio is present in a video. Will avprobe help with this ? Can anyone point me to a resource or probably a solution ?

    Edit : Surprisingly, the same command on my server running the latest build of ffprobe doesn’t run. It throws an error saying

    Unrecognized option ’select_stream’

    Failed to set value ’a’ for option ’select_stream’

    Any ideas how to rectify this out ?

  • How to create a video thumbnail without ffmpeg or HTML5 video canvas ? [duplicate]

    14 mai 2014, par user3631926

    This question already has an answer here :

    I need to create a thumbnail from a video, I have tried the below options but they didn’t work for my case. I am using S3 and CloudFront.

    1. ffmpeg is not supported via my hosting because I am using a shared hosting and I need to upgrade to VPS or dedicated server if I want to use ffmpeg.

    2. I tried taking a screenshot from the video using HTML5 drawImage and toDataURL functions, but it is throwing SecurityError because my video file is located on Amazon CloudFront and my code is hosted somewhere else.

    Is there any other option or a workaround to the second option ? I don’t want to upgrade my server for just the thumbnail issue.
