Random error "Failed to update header with correct duration."
22 juin 2017, par RMSI have a bash script that triggers a ffmpeg command, the loop strangely doesn’t start again after the error below randomly occurs :
Failed to update header with correct duration.
Failed to update header with correct filesize.I looked up everywhere, no luck. I dont mind the error, just why won’t the bash loop work correctly and relaunch the command ?
I am running a nginx server where I push the stream to, here is the script :
#!/bin/bash
until ffmpeg -thread_queue_size 512 -re -I "external URL" -vcodec copy -vprofile baseline -acodec aac -strict -2 -f flv "nginx URL"; do
echo "restarting ffmpeg command"
sleep 1
doneThank you !

Getting error "DLL load failed while importing rect : %1 is not a valid Win32 application" while importing package
17 août 2020, par Sagar DonadkarI am using cython package to call Cpp API and in my cpp code i am using ffmpeg library and able to build my code successfully using bellow command


python setup.py build_ext --inplace --compiler=msvc


but when i try to import generated pyd file then i get error


PS D:\SiVUE\Backend\Cython\demo> python
Python 3.8.3 (tags/v3.8.3:6f8c832, May 13 2020, 22:20:19) [MSC v.1925 32 bit (Intel)] on win32

My entire code is provided bellow


header file

rect.pyx file i am calling cpp API


# distutils: language = c++

from Rectangle cimport Rectangle

cdef class PyRectangle:
 cdef Rectangle c_rect # Hold a C++ instance which we're wrapping

 def __cinit__(self, int x0, int y0, int x1, int y1):

setup.py
I provided pyx file and ffmpeg library path as well as include path

 description = 'Python Package with superfastcode C++ extension',
