how can I take audio file(mp3) and video file(mp4) as input in Java spring ?
29 juillet 2022, par Jawad Un Islam AbirI am using this code to read the audio file. but don't know how to take user input.


InputStream inputStream = new FileInputStream("example.ogg");
FFmpegInput input = new FFmpegInput(inputStream);
FFmpegSourceStream stream = input.open(inputFormat);

stream.registerStreams();

Error in making animation through ffmpeg (python3.9)
20 avril 2024, par Taehyung GhimWhen I try to make 2D animation map for cow tracking(matching 2 camera views) through ffmpeg, following error occurs.



raise subprocess.CalledProcessError(subprocess.CalledProcessError: Command '['ffmpeg', '-f', 'rawvideo', '-vcodec', 'rawvideo', '-s', '4000x4000', '-pix_fmt', 'rgba', '-r', '5', '-loglevel', 'error', '-i', 'pipe:', '-vcodec', 'h264', '-pix_fmt', 'yuv420p', '-metadata', 'artist=Me', '-y', '../out_detect/run7/TRACKS_ANIMATION_fused.mp4']' returned non-zero exit status 1.

I am confident it has nothing to do with the animation data, the error occurs even when I create a simple test animation :


import numpy as np
from matplotlib import pyplot as plt
from matplotlib import animation
# plt.rcParams['animation.ffmpeg_path'] = '/usr/bin/ffmpeg'

fig = plt.figure()
ax = plt.axes(xlim=(0, 2), ylim=(-2, 2))
line, = ax.plot([], [], lw=2)


def init():
 line.set_data([], [])
 return line,


def animate(i):
 x = np.linspace(0, 2, 1000)
 y = np.sin(2 * np.pi * (x - 0.01 * i))
 line.set_data(x, y)
 return line,


anim = animation.FuncAnimation(fig, animate, init_func=init,
 frames=200, interval=20, blit=True)

FFwriter = animation.FFMpegWriter()
anim.save('basic_animation.mp4', writer=FFwriter)


I am currently using PyCharm in LinuxMint and I have a fairly new version of FFMpeg (4.2.4) installed. Given that FFMpeg complains about 'rawvideo' which as far as I understand it is just a bunch of images in series, it seems unlikely this has anything to do with codecs. If I run ffmpeg -formats, sure enough rawvideo is in the list.


I have tried manually setting plt.rcParams, like in the commented line in the code above, with no success. I have also tried setting up both anaconda and venv environments, but I get the same error.
Annoyingly, I did not have this problem a few months ago when I was using Ubuntu. I have also verified that it works on my friends Ubuntu desktop, using the same simple venv as I set up for myself.


Any ideas ?


EDIT : I use the fish shell, if that is relevant...


Well this is peculiar. If I start a terminal from within PyCharm and check supported formats, I get the following :

As is evident, there is no support for 'rawvideo' in the list above ! Very strange indeed, I do not know which ffmpeg this list belongs to, perhaps it is a version integrated into matplotlib's animation class ?


Anyway, if I uncomment the line setting the ffmpeg_path I am back at the old error. I did get it to work however, by changing the path from '/usr/bin/ffmpeg' to '/home/j/.conda/envs/venvtest/bin/ffmpeg'. Then I get the file to run, create the animation and save it. This works for my real files as well, which do not even run that particular conda-environment. They do not recognize or find the ffmpeg I have in /usr/bin though. I have no clue why but at least I have a workaround now.


Final edit :
