ffmpeg Error: Pattern type 'glob' was selected but globbing is not support ed by this libavformat build

Question

I'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.mp4

Based 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 implemented

Which 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?

Solution

-pattern_type glob requires glob.h.

glob is defined in the POSIX standard and it's not available on Windows by default.

Create/rename your files using sequential file naming image###.jpg then use sequence wildcards like -i image%03d.jpg as input.

Why is this down voted? there are many ffmpeg questions on Stackoveflow, ffmpeg is a legitimate video encoding library & API. I have also clearly stated my problem , attempt, and question?

By the way I got this kind of working by using ffmpeg input pattern -i img%1d.jpg entire command ffmpeg -y -framerate 1/2 -start_number 1 -i img%1d.jpg -vf scale=720:756 -c:v libx264 -r 30 -pix_fmt yuv420p video.mp4 however this only converts the 1st five frames/JPEG images why is there a limit, How can I convert any amount of JPEGs to a MPEG video?

Please refer to my July 3rd comment above, I solved the original problem , however ffmpeg only encodes 1st 5 files into video , not more, that's the current issue/problem. I need to encode "N" number of frames into a larger sequence.

Your question refers to glob, please consider updating it or posting a new one. I also commented on your original question. If you need a larger sequence just use %0n where n is the number of digits. How are your files named?

[cyber101]

As you see I already got that issue working on July 03, however it doesnt do more than 5 frames.

Then update the question and add the naming convention of your files. If you use a sequential index, is it always incremented by 1 without skipping?

Thanks it seems I was naming my files literary img01, img02, img03, etc... Instead of img1, img2, img3 , thanks for the help. Also are you familiar with actual Java API for ffmpeg , ho would I achieve the same result using API rather command line?

I actually used both Xuggler & JCodec initially which created the same output as ffmpeg , all three outputs play correctly on my PC, Mac, and , Android, however this is meant to play on a embedded device , and the only video that plays correctly on that device is the ffmpeg generated video, dont know why ,thats the reason I need to now compile ffmpeg src into ".ddl" or use "javah" option & access ffmpeg via JNI, I will post this question later today. Thanks a million buddy, but I have a ways to go now, fun , fun fun ...
