Python code to concat images and ts files using ffmpeg - python-3.x

Question

I have a folder with multiple ts files in it and I want to join the files by inserting an image for n number of duration between videos. Below is the list with the duration for which an image needs to be inserted for.
['00:00:06:17', '00:00:00:16', '00:00:01:05', '00:00:00:31', '00:00:01:01']
For example, if the folder has 5 ts files (this number might change so the folder needs to be iterable) then,
video1 + image for 00:00:06:17 + video2 + image for 00:00:00:16 + video 3, etc...
Any pointers will be much appreciated.
UPDATE:
for i in new_ts3:
for m in filename[:-1]:
p1 = subprocess.Popen (['ffmpeg', '-loop', '1', '-i', sys.argv[2], '-c:v', 'libx264', '-profile:v', 'high', '-t', i, '-pix_fmt', 'yuvj420p', '-vf', 'scale=1280:720', '-f', 'mpegts', '{}{}_.ts'.format((os.path.splitext(sys.argv[1]) [0]), m)], stdout=subprocess.PIPE)
out1 = p1.communicate()
break
where new_ts3 is ['00:00:06:17', '00:00:00:16', '00:00:01:05', '00:00:00:31', '00:00:01:01'] and
filename is ['file1', 'file2', 'file3', 'file4', 'file5', 'file6']
With the above, I am getting 5 files with different filenames but each file is of duration 00:00:06:17

import os
i = 0
image_list = ['img1.jpeg', 'img2.jpeg']
duration = ['1200', '1300']
## First we make loops of images to videos with given duration
for i in range(len(image_list)):
# change name according to whatever order you want to save the files format
outname = image_list[i] + str(i) + '.mp4'
dur = duration[i]
os.system(f'ffmpeg -loop 1 -i {images_list[i]} -c:v libx264 -t {dur} -pix_fmt yuv420p -vf scale=320:240 {outname}')
# Then we onvert .mp4 files to .mpeg if not in .mpeg format as .mp4 files have headers
for file_name in os.listdir(path):
if (filename.endswith(".mp4")):
out_name = filename.split(".")[0] + str(.ts)
os.system(f'ffmpeg -i filename -c copy -bsf:v h264_mp4toannexb -f mpegts {out_name}')
## create a list of the order in which you want to combine files here
order_list = [] # create with your own logic
new_out = 'out.ts'
file_list = os.listdir(path)
for i in range(len(file_list)-1):
new_out = 'out' + str(i) + '.ts'
os.system(f'ffmpeg -i "concat:{file_list[i]}|{file_list[i+1]}" -c copy {new_out}')
if (i+1 < len(file_list))
file_list[i+1] = new_out
else:
continue
## finally convert it to mp4 at the last step
the flags used in commands are mostly self explanatory such as scale of output.
In case of the last loop , we're simply updating the output file name every time by adding that to our file list and combining it with the next item in the list and pushing the output
You can convert the final .ts file to any format of your choice. Look for FFMPEG documentation and to execute it in python use the os.system
