  • How to extract video clip from larger video based on specific time and duration

    26 juillet 2022, par user19019404

    I have video clips that get created. Each video is recorded for 5 minutes and starts at a time e.g. 10:01:20 to 10:06:19 then the next video from 10:06:20 etc. These videos are recorded at a specific frame rate, be it 5 frames or 30 frames (its dependent on the platform making the recording). The net result is NOT a 5 minute video clip but might be a 2 minute video clip (where everyone moves very quickly in the view as a result of the frame rates). I cannot restrict a 1 to 1 recording as these are generated by external systems.

    


    I need to extract specific portions out of the video. For example I need to extract from 10:03:10 to 10:03:35 (25 seconds). This would equate to 10 seconds into the video up to 14 seconds into the video, in those 4 seconds of video, 25 real world seconds are displayed.

    


    My question is do you have any guidance as to how I can calculate that each second of recording actually means 10 or 12 seconds in real life, therefore go to this frame and record to this frame for example.

    


    I have been looking at cv2.CAP_PROP_FPS to get the video frame rates, CAP_PROP_POS_MSEC and CAP_PROP_FRAME_COUNT and believe the answer might lie there, but not sure.

    


    The thinking being if I work out the frame rate of the video, the total frames then I can divide the one by the other to get to how many frames make up real world seconds (this is where I fail). This way I can run from frame to frame as a result.

    


    Thank you

    


  • RTMP video streaming client without showing the video just need extensive log

    6 août 2016, par Amir

    I set up an RTMP video streaming server in a cloud environment for research purposes. On another VM in the cloud, I want to use a client to do some experiments. I have tried some different video player like VLC and FFplay but they are keep playing the video in the shell. As it is in the command line environment and to make sure my experiments are not biased with human errors, I need an RTMP video streaming client that just receives the stream as if it wanted to play it and log everything, for instance, if the playback stops due to buffering, average buffer size, etc.

    Thanks

  • Does FFmpeg download the video on server to generate screen shot from S3 video url ?

    13 décembre 2019, par Tashi

    I am running the following command to generate screenshot from an S3 video url in my server. I want to know if FFmpeg downloads the video to server disk or memory before generating the screenshot. Let me know if anyone knows about this, thanks.

    ffmpeg -i "http://bucket.s3.amazonaws.com/video.mp4" -ss 00:00:10 -vframes 1 -f image2 "screeenshot.jpg"
