Concatenating video files are always throws an error
Closed this issue · 6 comments
I just downloaded scripts bundle v4 and trying to concatenate 2 videos from https://pixabay.com/videos/wheat-wheat-field-nature-17285 and I always got "Error initializing complex filters. Result too large" message.
Scripts I've tried to execute are
- box*.sh
- collapse*.sh
- clock.sh
- fade*.sh
- rotate*.sh
- push*.sh
- wipe*.sh
Environment
- Windows 10 64bit
- 16 GB RAM
- FFmpeg 4.3.1
Full logs from fade-in script

Result too large
I'm not sure whether or not the problem occurs while calculating frame count. But I can confirm that CALCULATED_FRAME_COUNT variable is always empty/null.
These scripts are bash scripts. Some of the functions used inside them are not available in other terminals. How do you run them under Windows, do you have a bash terminal?
This is the error. end_frame shouldn't be -30.
'trim' with args 'start_frame=0:end_frame=-30'
I'm using git bash window.
Do you have another bash emulator in your machine?
It looks like the bash implementation in git for windows does not support some of the expressions used in the video scrips. The problem is, on Windows, there does not exist a standard bash terminal. There are different implementations and it is hard to test & support all of them. And, I don't want to modify the scripts to support a specific Windows bash implementation.
So, I'll suggest using another bash terminal if you can. If you don't want to try or it does not help, I'll refund the amount to your account.
No problem, I solved the issue by utilizing ffprobe to calculate number of frames. I don't know if this is the correct approach. Grabbing number of frames from .mf.counter file just doesn't works for me.
# TODO
# calculated frames count/(original FPS/desired fps)
CALCULATED_FRAME_COUNT=`ffprobe -v error -count_frames -select_streams v:0 -show_entries stream=nb_read_frames -of default=nokey=1:noprint_wrappers=1 ${FILE}`Well, not exactly. Each input video has a frame rate (A), and the scripts have a target frame rate (B). CALCULATED_FRAME_COUNT is used to calculate B.
Unfortunately your workaround calculates A using ffprobe and assigns it to B. If A and B is the same for your files then you won't have any issues. But if they're not then your slideshow may not run smoothly. You may see dropped frames during transitions.
I'll suggest using the original approach by updating that section about /tmp/.mf.counter and replacing it with a Windows compatible path, something like c:\temp\mf.counter.
