I'm trying to make the zoom video using image but facing


TypeError: must be real number, not NoneType.


It used was to run but I don't remember if I might have updated numpy, ffmpeg, or any thing else that is now causing the error. I have tried the code on python 3.10 and 3.11 and get the same error in both. I was previously running it on python 3.10.

What is the meaning of characters like [0 ;33m here ?


I thought it might have something to do with bit depth and color format. Setting
-pix_fmt grayhad no effect, and indeed the format of the jp2 images is already detected as 8-bit gray.

The output .avi exists and seems fine.


The line was previously used on jpeg files and works fine on jpeg. With jpeg, the output has the line

Python asyncio subprocess code returns "pipe closed by peer or os.write(pipe, data) raised exception."
4 novembre 2022, par Duke DougalI am trying to convert a synchronous Python process to asyncio. Any ideas what I am doing wrong ?


This is the synchronous code which successfully starts ffmpeg and converts a directory of webp files into a video.


import subprocess
import shlex
from os import listdir
from os.path import isfile, join

output_filename = 'output.mp4'
process = subprocess.Popen(shlex.split(f'ffmpeg -y -framerate 60 -i pipe: -vcodec libx265 -pix_fmt yuv420p -crf 24 output.mp4'), stdin=subprocess.PIPE)

thepath = '/home/ubuntu/webpfiles/'
thefiles = [f for f in listdir(thepath) if isfile(join(thepath, f))]
for filename in thefiles:
 absolute_path = f'{thepath}{filename}'
 with open(absolute_path, 'rb') as f:
 process.stdin.write(f.read())

process.stdin.close()
process.wait()
process.terminate()


This async code fails :


from os import listdir
from os.path import isfile, join
import shlex
import asyncio

outputfilename = 'output.mp4'

async def write_stdin(proc):
 thepath = '/home/ubuntu/webpfiles/'
 thefiles = [f for f in listdir(thepath) if isfile(join(thepath, f))]
 thefiles.sort()
 for filename in thefiles:
 absolute_path = f'{thepath}{filename}'
 with open(absolute_path, 'rb') as f:
 await proc.communicate(input=f.read())

async def create_ffmpeg_subprocess():
 bin = f'/home/ubuntu/bin/ffmpeg'
 params = f'-y -framerate 60 -i pipe: -vcodec libx265 -pix_fmt yuv420p -crf 24 {outputfilename}'
 proc = await asyncio.create_subprocess_exec(
 bin,
 *shlex.split(params),
 stdin=asyncio.subprocess.PIPE,
 stdout=asyncio.subprocess.PIPE,
 stderr=asyncio.subprocess.PIPE,
 )
 return proc

async def start():
 loop = asyncio.get_event_loop()
 proc = await create_ffmpeg_subprocess()
 task_stdout = loop.create_task(write_stdin(proc))
 await asyncio.gather(task_stdout)

if __name__ == '__main__':
 asyncio.run(start())


The output for the async code is :


pipe closed by peer or os.write(pipe, data) raised exception.
pipe closed by peer or os.write(pipe, data) raised exception.
pipe closed by peer or os.write(pipe, data) raised exception.

etc - one line for each webp file
