what is this error PermissionError: [Errno 13] Permission denied: 'ffmpeg'

with below function , it is happening only on android platform not on ubuntu .

what all I want is to create thumbnail for the video path given to function .

def thumforvideo(self , path):

print(datetime.utcnow().strftime('%Y-%m-%d %H:%M:%S.%f')[:-3])

result = os.path.basename(path)[:-3] + "jpg"

print(result)

ff = FFmpeg( inputs = {str(path): None} ,

outputs = {str(result): ['-ss', '00:00:4', '-vframes', '1']} )

print(ff.cmd)

# Print result

# ffmpeg -i input.mp4 -ss 00:00:10 -vframes 1 output.png

ff.run()

print(datetime.utcnow().strftime('%Y-%m-%d %H:%M:%S.%f')[:-3])

print(os.listdir())

The error occurs because is no ffmpeg executable on Android, only the .so files (if ffmpeg is in requirements).

Generally the easiest way to get a thumbnail is with Pillow.

But I don't know if that applies to a video.

The build process included the wrong .so file.

If you change the arch from arm7 to arm8, appclean, and rebuild you will get a different error.

This will probably say it is trying to link an x86_64 object.

This was sucked in from pypl because of a requirements specification error in buildozer.spec

One of your requirements needs a recipe (or needs to be specified differently).

Perhaps you specified opencv as cv2 not opencv which is the recipe name?

among those choices which one should I chose ?

what should I change among requirements ?

I dont know about recipes , what are they , how to use them ?

The arch thing explains how to verify the diagnosis, it is not required.

Others have seen this issue, but I don't know anything about it. Sorry

This might be a place to start https://github.com/kivy/buildozer/issues/1144

So I read that thread, as far as I understand it OpenCV is not compatible with the current Google tools.

The OpenCV compile process depends on old tools that are not in the tools version Buildozer downloads from Google.

So OpenCV has bitrot.

The link contains some hacks to add the required tools.

what is this below error ? I am trying to run below function .

print(os.listdir())

print("started thumbnail making...."*(50))

# Read the video from specified path

cam = cv2.VideoCapture(path)

try:

# creating a folder named data

if not os.path.exists('data'):

os.makedirs('data')

# if not created then raise error

except OSError:

print ('Error: Creating directory of data')

# frame

currentframe = 0

done = False

while(True):

# reading from frame

ret,frame = cam.read()

if ret and not done :

if currentframe > 5 :

result = os.path.basename(path)[:-3] + "jpg"

# if video is still left continue creating images

name = result #'./data/frame' + str(currentframe) + '.jpg'

print('Creating...' + name)

cv2.imwrite(name, frame)

# increasing counter so that it will

# show how many frames are created

currentframe += 1

done = True

else:

break

# Release all space and windows once done

cam.release()

cv2.destroyAllWindows()

There are multiple OS crashes here, all originating in opencv.

The first appears to be

crash_dump32: cannot open libmiuindbg.so: No such file or directory

I don't know enough about Opencv to answer your question, but one thing I notice:

cv2.destroyAllWindows()

Android is not a windowing operating system, if you are trying to create windows it will crash.

Below is my initial question , and your reply .

you said something about .so file . I have no clue about .SO files , can you please explain in detail .

I found these https://github.com/kivy/python-for-android/issues/2345 , https://github.com/kivy/buildozer/issues/1247 in which you replied to similar question anout FFMPEG in android , but nothing is in detailed .

I need your help badly to finish a small android app .

I need to use FFMPEG to many case in my android app for video editing .

=======================my initial question ===================

what is this error PermissionError: [Errno 13] Permission denied: 'ffmpeg'

with below function , it is happening only on android platform not on ubuntu .

what all I want is to create thumbnail for the video path given to function .

def thumforvideo(self , path):

print(datetime.utcnow().strftime('%Y-%m-%d %H:%M:%S.%f')[:-3])

result = os.path.basename(path)[:-3] + "jpg"

print(result)

ff = FFmpeg( inputs = {str(path): None} ,

outputs = {str(result): ['-ss', '00:00:4', '-vframes', '1']} )

print(ff.cmd)

# Print result

# ffmpeg -i input.mp4 -ss 00:00:10 -vframes 1 output.png

ff.run()

print(datetime.utcnow().strftime('%Y-%m-%d %H:%M:%S.%f')[:-3])

print(os.listdir())

==================your reply ==================

The error occurs because is no ffmpeg executable on Android, only the .so files (if ffmpeg is in requirements).

The way you are trying to do this is not going to work because the executable does not exist on Android.

It is presumably possible to link the binary components of ffmpeg (.so files) but I don't have an example.

but FFMPEG is in list of recipes of p4a . then what is the issue here ? why permission denied error ?

Do you know any other pure python module or recipe for video editing , cutting , thumbnail creation ?

There is no executable, just the .so
