How can I save this data into a video file which can be played ? I am starting to read from live stream at a certain point in time and reading it for few seconds - ex. 5 seconds. I need to have a video of that 5 seconds.


Note, when I use the url : http://192.168.1.33, I can see the video on the browser.

6 août 2020, par JOHN DADSi 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 mars 2020, par SandeepI 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 tfdsdf_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.
