Error exporting animation ffmpeg - Matplotlib
4 décembre 2020, par jonboyI'm having issues with exporting an animation using python through anaconda on a Mac. I'm getting the following
RuntimeError
.

RuntimeError: Requested MovieWriter (ffmpeg) not available



Looking at other questions, the main options are to install
ffmpeg
via conda :

conda install -c conda-forge ffmpeg



Or designate the path :


plt.rcParams['animation.ffmpeg_path'] = '/usr/local/bin/ffmpeg'



The second option just returns the same
RuntimeError
. The first option returns a separate error :

BrokenPipeError: [Errno 32] Broken pipe


During handling of the above exception, another exception occurred:

Traceback (most recent call last):

Chasing up this error then refers me back to uninstalling the
ffmpeg
package. But this just leads to the initial error statingffmpeg
isn't available.

ffmpeg break up videos with frame persecond
25 mai 2018, par jameshwart lopezTheres a command to extract images of a video providing frame per seconds
ffmpeg -i "vide.mp4" -vf fps=1 frames/frame_%04d.png -hide_banner
Is there a command in ffmpeg to cut video providing fps and save it as video(.mp4 / avi) file like the command above ?
What i currently have is i created a method to cut the videos with start and endtime but i firstly created a method to get the length of a video so that i could cut the video base on how many frames that was generated by the above command.
def get_length(self):
"""
Gets the length of a video in seconds
Returns:
float : Length of the video
"""
print("Getting video length: " + self.video_string_path)
command = 'ffprobe -i "'+self.video_string_path+'" -show_entries format=duration -v quiet -of csv="p=0"'
self.command = command
length = str(cmd.execute(command)).strip()
print("lenght: "+length+" second(s)")
return float(length)
def cut(self, start_time, duration, output_file_name = 'output_file_name.mp4', save_to =''):
"""
Cut a video on a specific start time of the video and duration.

Parameters:
start_time : string
is the value of ffmpeg -ss with the format: 00:00:00.000
duration : string | int | float
is the end point where the video will be cut. Can be the same with start_time format but it could also handle integer as in seconds
output_file_name : string

save_to : string | optional
