How to copy ffprobe dumped metadata to a converted video
23 mai 2020, par QuerI hope you're all doing safe ! I'm using windows 10 and have lots of home videos, some of them are on
.AVI
format. I just discovered google photos don't backup.AVI
videos, I tried converting it with GUI converters (FormatFactory, Wondershare, HandBrake) but when I tried to back it up, it wasn't preserving the metadata of my newly converted videos.


I tried further research on this matter and I stumble upon ffmpeg (w/c the GUIs were using). I successfully converted
.MOV
while preserving metadata using :


ffmpeg -i in.MOV -b:v 73000k -c:v libx264 -c:a aac -strict -2 -map_metadata 0 out.mp4




but when I tried converting
.AVI
videos, with the command above, it doesn't retain the original metadata for theout.mp4
.


I tried another approach and I found out a method of dumping the metadata on a
.txt
then restoring it on theout.mp4
.


ffprobe -v error -show_format -show_streams DSCF0421.AVI > output.txt 2>&1




The command above does save it on the
output.txt

It doesn't successfully restore the metadata of the source
.AVI



BTW, I don't intend to shrink the size of the video I just need to retain its created date and some miscellaneous.



Thank you in advance for those who will answer !

ffmpeg takes a while to start
17 octobre 2020, par SuspendedI have this command in python script, in a loop :


ffmpeg -i somefile.mp4 -ss 00:03:12 -t 00:00:35 piece.mp4 -loglevel error -stats



It cuts out pieces of input file (-i). Input filename, as well as start time (-ss) and length of the piece I cut out (-t) varies, so it reads number of mp4 files and cuts out number of pieces from each one. During execution of the script it might be called around 100 times. My problem is that each time before it starts, there is a delay of few seconds and it adds up to significant time. How can I get it to start immediately ?


The script (process_videos.py) :


import subprocess

 """TimeFormatter class (TF).
This class' reason for being is to convert time in short

process_videos.py is called from bash terminal like this :


$ python process_videos.py video_data 



video_data file has the following format :


BEGIN
!first_video.mp4!3-23,55-1:34,2:01-3:15,3:34-3:44!
!second_video.mp4!2-7,12-44,1:03-1:33!
