  • Vinyl record animation with ffmpeg

    14 avril 2023, par pabsdenn

    Is it possible to archive this with ffmpeg ?

    


    Basically I want to have a black or vinyl background, one circle for the cover and one circle for the hole. I then need to replace the cover with an image of 500x500px and let it rotate as loop with a certain speed.

    


    Or is it better to automate it with e.g. After Effects ?

    


  • Generate individual HLS-compatible .ts segments on-demand by downloading as little bytes as possible from a remote input file

    28 juillet 2017, par Romain Cointepas

    I’m trying to generate individual HLS-compatible .ts segments on-demand by downloading/reading as little bytes as possible from a remote input file (hosted on a server supporting byte-ranges requests).

    One of the application for this would be to be able to transcode and play on Apple TV (via Airplay) a remote file that is not Airplay compatible, without having to download the entire file first.

    I am generating the playlist myself, and I have access to the ffprobe results for the remote file (that gives video duration, etc.).

    I have something working that plays via Airplay but with small video and audio glitches between each segments when I use the following command to generate each segment :

    ffmpeg -ss 60 -t 6 -i http://s3.amazonaws.com/misc-12345/avicii.vob -f mpegts -map 0:v:0 -map 0:a:0 -c:v libx264 -bsf:v h264_mp4toannexb -force_key_frames "expr:gte(t,n_forced*6)" -forced-idr 1 -pix_fmt yuv420p -colorspace bt709 -c:a aac -async 1 -preset ultrafast pipe:1

    Note : above command is for segment 11.ts, and in the m3u8 playlist I advertise each segment duration as 6 seconds.

    Here is a Youtube video showing the audio/video glitches between segments :

    The segment or hls modules of ffmpeg can’t be used because they both generate all the segments at once.

    I’ve been struggling on this for some days now and I would really appreciate some help !
