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

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 !
