Can't save matplotlib animation (ffmpeg)
25 mai 2014, par rengerI am trying to get a simple animation saved using ffmpeg. I followed a tutorial to install ffmpeg, and I can now access it from the command prompt.
Now I run this piece of code :
import numpy as np
from matplotlib import pyplot as plt
from matplotlib import animation
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)
mywriter = animation.FFMpegWriter()
anim.save('mymovie.mp4',writer=mywriter)
plt.show()I get this error :
Traceback (most recent call last):

WindowsError: [Error 2] Het systeem kan het opgegeven bestand niet vinden

What do these errors mean, and how can I solve them ?

Song name under video
2 septembre 2020, par ottpeterI'm trying to write the song name under the video with ffmpeg. My mp3 files are running in a loop like this :

-stream_loop -1 -i music.txt
My workaround would be to write an SRT file with timecodes, a script would determine when next song is comming, and I would repeat this, let's say, a 1000 times (time codes adjusted), then I would get song names for a month for example. (this would be done before ffmpeg is started)
Obviously this is not optimal, especially because I can't loop the SRT file as well, because of the timecode. It would be better to do this with a filter complex.

Is there a way to know the name of the mp3 that is currently playing, in ffmpeg ?

Is there a case where I can not create a file if I run a lot of threads ? ( feat. Ffmpeg, thread)
26 juin 2018, par JunburgI am now creating an app that will duet with the singer. We use a thread (mAudioPlayer) that outputs background music, a vAudioPlayer that prints the voice of the singer, a mRecordThread that records the voice of the user, and a thread that weaves and attaches each file (mp3ConcatThread).
It works by stopping the singer’s voice while recording background music and recording by the user. Of course, when the user does not record, the singer’s voice is output. In this way, each section must be made into an mp3 file and merged into a single file. However, it often happens that files that do not record and merge properly are created.
Audio processing is done using Ffmpeg. I guess the following error might be the reason.
06-26 21:37:11.084 13017-13017/com.softcode.kihnoplay I/Choreographer: Skipped 72 frames! The application may be doing too much work on its main thread.Could not generate a file because of this kind of error ?
If you know the answer to this question, please answer. Thank you.
