    My opencv code is perfectly open any video file and decently play it . But when I open the rtsp h.264 video stream then there have **following errors messages :

    Last message repeated 1 times

  • fluent-ffmpeg processing is very slow in Cloud Run

    18 août 2021, par Nazarii Kahaniak

    I am trying to merge multiple short videos in the container in Cloud Run using the node.js fluent-ffmpeg package. It takes 20 seconds max to merge videos locally. When I am making a request to clour run to merge the videos it processes them very slowly and after 30 minutes just stops (I assume that's because 1800 seconds timeout is set).
I tried to allocate to 2 CPUs with 8GB each but that didn't help. Within 30 minutes the video is processed by about 30 % as I can see in the cloud run logs.
Any feedback is appreciated !

    


  • 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 !
