  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

  • How to control insert position when insert video frames to pure audio file with ffmpeg

    6 mai 2014, par teddy

    Inserting video frames into pure audio flv file(may call it audio.flv) can make it seekable.I do this with ffmpeg using the following command :

    /usr/bin/ffmpeg -y -loop 1 -i /root/testimage.jpg -i /file/audio.flv -s 2x2 -t 90 -r 1 -g 0 -acodec copy /tmp/out.flv 2>&1

    The number 90 in command is specify the file duration.this can work well except one thing : The output files for several executions of the previous command is not same. After i analysed the file’s with flvparser i found that the position of the first video tag of these files were not same.

    1. For the first situation, the first video tag is the third tag, which is following script tag
    2. For the second situation, the first video tag is the fifth tag, there are three audio tags between it and script tag.
    3. For the third situation, the first video tag is the sixth tag.

    I just got these three situations for my test. But other video tags are in the same position of tag-index in output file. I have no idea why is just the first video tag has different position. I want all video tag will be at same tag-indexes. Could anyone give me some advise ? Thanks !
