  • How to use ffmpeg to encode isolated motion vectors (using codecview)

    22 juillet 2021, par Temmeh

    I have been successfully using this command to superimpose MPEG motion vectors onto a video :

    


    ffmpeg -v error -flags2 +export_mvs -i input.mp4 -vf codecview=mv=pf+bf+bb -y output.mp4

    


    Now I would like to be able to export an h264 mp4 of just the motion vector arrows, like in this example, without the original video layered underneath. I checked the codecview documentation and and did not find a flag or option to do this.

    


    Any help is appreciated !

    


  • Downloading earlier segments from a live m3u8 playlist

    25 juillet 2016, par Zafer Cesur

    I have an .m3u8 URI from an online live-stream. As far as I know, live playlists use a sliding window instead of containing all the segments. My questions are,


    1) Is it possible to find out what the length of the window is (time or frame-wise) ? My intention is to use the playlist I have to download a live-stream starting from an earlier time.

    2) If yes, how do I get the earlier segments, i.e., how do I specify where I want to start downloading from ? I tried something like ffmpeg -ss -00:00:10 -i "in.m3u8" out.mp4, but it did not work.

    I do not have much experience in video-encoding or live-streaming, and I would appreciate any direction ! The file that I am dealing with is printed below.

  • Stopped ffmpeg ip camera recording

    25 août 2016, par Amit Yadav

    I am using foscam ip camera. I want to record its stream in ts chunks and put no video screen when there is no stream available. I want to record 24 hrs video but I am not able to record it up to 24 hr. FFMPEG command stops inbetween. I am using below ffmpeg command

    ffmpeg -rtsp_transport tcp -i rtsp ://username:password@192.168.0.68:554/videoMain -t 86400 -c:v copy -c:a copy -map 0 -f segment -segment_time 10 -strftime 1 -segment_list_type m3u8 -segment_list /home/user/Desktop/rec/del20160725111733.m3u8 -segment_format ts -y /home/user/Desktop/rec/%Y%m%d%H%M%S.ts

    want no video screen like this http://www.electro-tech-online.com/customimages/2011/03/preview409-1.jpg

    Or any other way to record stream using java code so that I have more control over stream to check if it is recording or not.
