  • How to batch auto-generate videos according to audio length

    16 septembre 2020, par yociba

    I have hundreds of folders of Spanish short stories, with each folder having dozens of individual .MP3 files for each dialogue spoken. Along with the .MP3 files, lies in the folder, a JSON file of the format ["folder1-dialogue-1", "folder1-dialogue-2",...].

    


    I want to generate images, each containing the text values of the JSON file, like folder1-dialogue-1 and generate videos combining that image with its corresponding audio (folder1-dialogue-1.mp3), and then merge all the videos in the folder into one - folder1.mp4

    


    How do I go about doing this ?

    


    P.S I'm not straight up asking for code, but just advice as to how I go about doing this.

    


  • How to detect silence in a pyAV AudioFrame ?

    29 janvier 2024, par Sachin Dole

    I want to process streaming audio (coming in from a person speaking on the peer of a webRTC peer connection) to detect when the person is done talking. I have got the audio track and access to individual frames. I see that each frame can be converted to an nd_array using Frame.to_ndarray. I can also see values in the ndarray changing depending on what the person is speaking, what pitch, what volume etc. Now, I want to detect silence on the stream. My question is what is in the ndarray and how can I make sense of the data ?

    


            while True:
            try:
                frame:AudioFrame = await track.recv()
                frame_nd_array = frame.to_ndarray() 


    


    Where can I learn what is in the frame_nd_array ?

    


  • Is it possible to pipe an ffmpeg output with multiple files (HLS or DASH)

    29 août 2020, par New Dev

    I'm using FFmpeg to generate fragmented MP4s in a dash and HLS format.

    


    ffmpeg -i input.mov -f dash -seg_duration 6 -hls_playlist true output.mbd


    


    The above (simplified) command outputs multiple files, in addition to output.mdb (e.g. actual segments, master.m3u8, etc...)

    


    Is there a way to get each produced file into their individual and separate output streams ?

    


    


    Broader context :

    


    I'm trying to build a transcoder in Node.js running in Google Cloud, with the idea being that it writes directly to a Google Storage through a writable stream. I can only create a stream per file, but since the number of files is dynamic, I'm not sure how to obtain a stream from each file.
