  • Record low quality video using avcodec dll(Getting frame per second value 0 in video)

    10 août 2017, par IPS

    I am working on record video from live camera using avcodec dll(version 52). For record video I am using command : "rtsp ://192.xxx.x.xx/axis-media/media.amp ?resolution=320x240&compression=60", by using this command video getting record but it is record video with single image(not moving video) and frame per second value is 0 and if I am using the same command but with higher resolution value "rtsp ://192.xxx.x.xx/axis-media/media.amp ?resolution=640x480&compression=60", then video getting record with proper format and proper frame per second value.

    Please help here if anyone having idea.

  • ffmpeg Copy From Input Video To Output Video

    31 janvier 2023, par user121392

    I have encountered the issue of faded/washed out colours after reencoding my library of phone videos from H264 to HEVC using ffmpeg. The command I used was

    


    ffmpeg -i input.mp4 -vcodec libx265 -o output.mp4

    


    Some searching have found that colour metadata from the input video are missing in the output video. An answer I found only addresses it specifically for a given input video. Is there a way to "copy" or "transfer" the metadata from the input video without having to go through the parameters on ffprobe ?

    


  • How can I split a series of clips from a video and then stitch them together without audio or video gaps ?

    16 avril 2020, par Dr. Cyber Sec

    I'm developing an application where I take a video and (1) split it up into a bunch of 1 second chunks. Then, I need to (2) stitch a subset of those chunks back together, resulting in a slice of the original video.

    



    For example, let's say I have an original, 10s clip. I split it up into 1s chunks for each second (a clip from 0s to 1s, a clip from 1s to 2s, etc.). I now need to stitch, say, seconds 2-4 together into one video.

    



    I'm currently attempting both steps using ffmpeg.

    



    For clip-cutting :

    



    ffmpeg -ss 33 -i video.ts -t 1 33to34.ts


    



    This should seek to second 33 and output a 1s clip duration, yielding a video clip containing seconds 33-34 of the original video. I noticed that ffmpeg doesn't always seek accurately, so after following the instructions in this post, which says to manually add keyframes to the parts of the video you want to cut, I tried this :

    



    First, setting the keyframes :

    



    ffmpeg -i video.ts -force_key_frames 00:00:01.000,00:00:02.000,00:00:03.000,00:00:04.000 out.ts


    



    And then cutting the clips as I did before with the new output clip.

    



    While this did get the videos to be exactly 1s long each, (which I wanted) there is a small gap (just a slight jitter) in audio when I combine the clips back together. I cannot have this, and am looking for a solution.

    



    Can anyone help me understand why this is happening and help me find a solution ? Thank you so much in advance.
