  • HTML5 audio and video support

    13 avril 2011, par

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
    For older browsers the Flowplayer flash fallback is used.

  • Get duration of encrypted video file

    22 mars 2019, par Grant Jamieson

    When using the commands :

    ffmpeg -i filename 2>&1 | grep Duration 
    
ffprobe filename -show_format -hide_banner

    The duration and bit rate appears as N/A but the rest of the format is correct, I believe this is because the file is encrypted using Lynk. I am wondering if there is away around this issue to get the duration even with the file being encrypted ?

    And this is program related as I use this command in a php script.

    Thanks

  • Concatenating slideshows and normal videos causes audio bleeding

    28 janvier 2019, par Zurechtweiser

    I noticed audio bleeding with concatenated videos containing alternating slideshows and normal videos.

    My commands

    ffmpeg -y -ss 00:00:04.391 -to 00:02:17.171 -i "test.MP4" -r 60 -c:v libx264 -af afade=t=in:ss=0:d=1,afade=t=out:st='00\:02\:11.780':d=1 25.mp4
    
ffmpeg -y -i 25.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts 25f.ts
    

    
ffmpeg -y -loop 1 -i "test.JPG" -t 2 -f lavfi -i anullsrc=channel_layout=stereo:sample_rate=44100 -shortest -r 60 -c:v libx264 -c:a aac -pix_fmt yuv420p -vf scale=-2:1080,pad=width=1920:height=1080:x=240:y=0:color=black 26.mp4
    
ffmpeg -y -i 26.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts 26f.ts
    

    
ffmpeg -y -i "concat:25f.ts|26f.ts" -bsf:a aac_adtstoasc -movflags faststart -c copy "final.mp4"

    The rest of audio of test.MP4 bleeds into the beginning of the test.JPG-single frame slideshow.

    I presumed a different framerate to cause it, but adding -r 60 didn’t solve the issue.

    Also it seems that the video player interpretes the final video as a set of single videos, as whenever a "new" video shows up, it stutters slightly and loses framerate.

    How do I concat them without bleeding and create a final video without stuttering ?
