  • Concat video output does not skip ahead or go backwards like normal video

    6 August 2020, by JOHN DADS

    i ran this basic concat code to combine an image and audio to output an mp4 video but the output video plays perfectly except for the fact that if I want to skip ahead in the video it goes back to the original position. This was run on python

    


    audio = ffmpeg.input("beat.mp3")

picture = ffmpeg.input("image.jpg")

ffmpeg.concat(picture, audio, v=1, a=1).output("video3.mp4").run()


    


  • tensorflow 2, tfds.features.Video Usage for video decoding

    5 March 2020, by Sandeep

    I am trying to decode a video in tensorflow 2 using tfds.features.Video , so that the output is a "tf.Tensor of type tf.uint8 and shape [num_frames, height, width, channels]" using following code :

    import numpy as np
    import pandas as pd
    import tensorflow as tf
    import tensorflow_datasets as tfds

    df_trains= pd.DataFrame()
    df_trains[’video_files’]= [’aa.mp4’]

    files_ds = tf.data.Dataset.from_tensor_slices(df_trains.video_files)
    video_class = tfds.features.Video(shape=(None, 1080, 1920,3), encoding_format=’png’, ffmpeg_extra_args=())
    a= video_class.decode_example(files_ds)

    However it generates following error:
    "AssertionError: Feature Video can only be decoded when defined as top-level feature, through info.features.decode_example()"

    I am unable to solve it, please help in this regard.

  • Video play VLC player only in Android(Video Recording using FFmpeg)

    28 July 2017, by Astro

    I am trying to record video from url, its fine I can record video from my url but the problem is the recorded video only play VLC player, can’t play no other video players. I think it is the problem of video encoding. my url is http://192.168.1.1:8080/?action=stream . So I have getting mpeg encoded frames from this url. I used different ffmpeg command but these are not worked properly. These are the command I used.

    "ffmpeg -i "+URL+" -codec:v libx264 -c:a aac -movflags +faststart "+toFile;
    

    
"ffmepg -i "+URL+" -acodec libfaac -ab 96k -vcodec libx264 -vpre slower -vpre main -level 21 -refs 2 -b 345k -bt 345k -threads 0 -s 640×360 "+toFile;

    So anyone knows how to fix these problem please help me...
