    I want to join these codes in a one code. My aim mix mp3 audio and video audio without delete the video sound and then use the codes below. Mp3 sound duration is too short that's why I want to hear the sound till the video finishes. But I couldn't manage to join them. Need your help thanks...

    


  • FFMPEG Conversion from GIF to video with audio, take too long

    5 novembre 2020, par Mouaad Abdelghafour AITALI

    I'm trying to convert a GIF file into 720p video and merge it with audio, the code below works fine, but it takes a long time to finish the process (depends on the audio length) :

    


    //Converting from GIF to video is fast!

public static String makeVideo(String inputGifPath, String outputPath, int width, int height) {
        return "-y -i " + inputGifPath + " -movflags faststart -pix_fmt yuv420p -vf crop=" + width + ":" + height + ":0:40,scale=1280:720,setsar=1 " + outputPath;
    }



//Merging video with audio takes a lot of time!

public static String addAudio(String audioNoSpace, String inputVideoPath, String outputVideoPath) {
    return "-stream_loop -1 -i " + inputVideoPath + " -i " + audioNoSpace + " -shortest -map 0:v:0 -map 1:a:0 -y " + outputVideoPath;
}


    


    FFMPEG commands :

    


    -y -i file.gif  -movflags faststart -pix_fmt yuv420p -vf crop=540:250:0:40,scale=1280:720,setsar=1 video.mp4

-stream_loop -1 -i video.mp4 -i  audio.wav -shortest -map 0:v:0 -map 1:a:0 -y final_video.mp4

  • cv2.VideoCapture() taking extremely long time to connect and returning empty frames

    18 novembre 2022, par John Schmidt

    When executing the code

    


    cap = cv2.VideoCapture('udp://127.0.0.1:1080',cv2.CAP_FFMPEG)


    


    The script will yield for at least a minute, and then connect. Along with that, it seems that, almost at random, the script will completely break and cv2.VideoCapture() will return nothing. the stream is initiated with the command

    


    ffmpeg.exe -y -f dshow -thread_queue_size 4096 -hwaccel cuda -hwaccel_output_format cuda -i video="OBS Virtual Camera" -f rawvideo -c:v mjpeg -qscale:v 0 -r 20 udp://127.0.0.1:1080


    


    if that helps any.

    


    I tried many different methods of starting the stream, color formats, and more. Still, they all had this issue.

    


    (note this does work sometimes, but seemingly at random will completely stop working for many days to come, and then suddenly begin working)
