    18 mars 2019, par user3787734

    As I m using an external .mpd file path, as playlist get a refresh every 10 seconds but FFmpeg can’t able to manage it out.

  • I-Frames replacement in MPEG DASH

    7 mars 2019, par Hangil Kang

    We are conducting a research which requires to change only I-Frames in the middle of MPEG DASH service.

    Based on my knowledge, each segment of a full video contains one I frame and related B and P frames. For our research, we want to do something with only I frames and re-encode the frames into the corresponding segment and during the decoding process, we want to do something with the I frames again.

    Any ideas how to do this ?

    I appreciate all comments.

  • minimum delay for mpeg-dash stream using ffmpeg

    9 février 2017, par evan

    I am trying to stream my video files using MP4Box and ffmpeg and using mpeg-dash, I transcoded my video using this command for video :

    ffmpeg -i main720.MTS -movflags faststart -vcodec libx264 -r 24 -tune zerolatency -tune fastdecode -bf 0 -slices 0 -x264opts intra_refresh=1 -g 96 -b:v 700k -maxrate 700k -bufsize 400k -an -s 640*360 -ss 00:00:00 -t 00:02:00 main720_700_video.mp4

    and this for audio :

    ffmpeg -i main720.MTS -movflags faststart -acodec libmp3lame -b:a 128k -vn -ss 00:00:00 -t 00:02:00 main720_700_audio.mp4

    and this to make the mpeg-dash file :

    MP4Box -dash 4000 -frag 4000 -profile onDamand -rap -segment-name %s_ -out manifest.mpd main720_300_video.mp4 main720_700_video.mp4 main720_300_audio.mp4

    but I am NOT getting a fast stream and it has got some delay, any suggestions on how to make this delay lower ??
