ffmpeg Error : Pattern type 'glob' was selected but globbing is not support ed by this libavformat build
14 septembre 2017, par Aryan NaimI’m trying to convert group of ".jpg" files acting as individual frames into 1 single mpeg video ".mp4"
Example parameters i used :
frame duration = 2 secs
frame rate = 30 fps
encoder = libx264 (mpeg)
input pattern = "*.jpg"
output pattern = video.mp4Based on ffmpeg wiki instructions at (https://trac.ffmpeg.org/wiki/Create%20a%20video%20slideshow%20from%20images), I issued this command :
ffmpeg -framerate 1/2 -pattern_type glob -i "*.jpg" -c:v libx264 -r 30 -pix_fmt yuv420p video.mp4
But I’m getting this error :
[image2 @ 049ab120] Pattern type 'glob' was selected but globbing is not
supported by this libavformat build *.jpg: Function not implementedWhich probably means the API pattern matching commands for my build/version have changed. By the way this my windows 32bit ffmpeg download build (
ffmpeg-20150702-git-03b2b40-win32-static
).How can I choose a group of files using pattern matching using ffmpeg ?

Combining Audio and Video file in python [duplicate]
8 juin 2020, par ysoI'm trying to understand how to us ffmpeg to combine video and audio files in python. I want to combine a .avi file and a .wav file to create a final .avi file. Is this the right approach ? I'm confused by the ffmpeg syntax.
Any help would be great.



I was looking through this for help :
https://wiki.libav.org/Snippets/avconv#Combine_audio_and_video_file



import ffmpeg
import subprocess

cmd = 'ffmpeg -i inputvideo.avi -i inputaudio.wav -c:v copy -c:a aac output_video_and audio.avi'
subprocess.call(cmd, shell=True) # "Muxing Done
print('Muxing Done')

Raspberry Pi : Playing multiple video files in mkfifo pipe
19 janvier 2017, par user3246167I have 2 files, test.mp4 and test2.mp4 that I want to play concurrently with no noticeable break in the middle. Currently I’m using
mkfifo test
cat test.mp4 > test &
cat test2.mp4 > test &
omxplayer testHowever, when I do this, omxplayer just returns data and doesn’t play the file. But if I just put a single file into the pipe, omxplayer shows it normally. I’ve also tried using the copy command in ffmpeg, and that also just returns data, doesn’t play the file.
I understand that I can just concatenate the 2 files together, but that will not work for my purposes, because I will need to be able to feed files to the pipe while omxplayer is running
