  • FFmpeg Live Stream - Loop Video ?

    15 décembre 2015, par Dread-Eye

    I am trying to stream a video loop to justin.tv using FFmpeg ? I have managed to loop an image sequence and combine it with line in audio :

    ffmpeg -loop 1 -i imageSequence%04d.jpg -f alsa -ac 2 -ar 22050 -ab 64k \
  -i pulse -acodec adpcm_swf -r 10 -vcodec flv \
  -f flv rtmp ://live.justin.tv/app/

    Is it possible to do this with a video file ?

  • Http Live Streaming EXT-X-STREAM-INF, Calculating BANDWITH

    26 juin 2012, par Agzam

    Initially I've tried to find possible ways to do HLS segmenting on other non-Mac platforms.

    Segmenting videos for HLS involves the following steps :

    1) Splitting the encoded video into segments

    2) Creating playlist (.m3u8) file that simply contains list of segments for the current rendition, including duration in seconds for each segment

    3) Creating a variant playlist that contains relative paths to all playlists of all renditions with the information about BANDWITH which according to HTTP Live streaming protocol is :

    The value is a decimal-integer of bits per second. It MUST be an upper bound of the overall bitrate of each media segment (calculated to include container overhead) that appears or will appear in the Playlist.

    Latest version of ffmpeg includes possibilities of splitting videos. However ffmpeg can’t create m3u8 files. Creating simple playlist not a problem. But creating variant playlist might be :

    So variantplaylistcreator on Mac creates those, calculates somehow bitrates and puts value based on that into BANDWITH tag.

    I’ve tried many different ways but yet I couldn’t get exactly the same numbers that variantplaylistcreator does, and at this point I can’t find any information how exactly it calculates those values and what algorithm it uses.
    My numbers are close, but still slightly different.

    In theory it should not be a problem, but the point is - I don’t know that for sure.
    Maybe the BANDWITH information should be precise for flawless video playing, maybe it doesn’t have to.

    Anyway I'm really curious how exactly variantplaylistcreator calculates them :
