Mobile-ffmpeg: Filter command is failed to be executed because ffmpeg cannot open transform file "transforms.trf"

[SembaMax]

First thank you for this awesome library 👏
Description
I'm trying to execute filter command as following:
"ffmpeg -i -threads 2 -vf [in]deflicker,dejudder[p0];[p0]vidstabdetect=shakiness=10:accuracy=15:result=transforms.trf[out] -f null -"

Unfortunately this's not working.
Here's the command i use in kotlin.
val cmd = "-i ${inputVideo.path} -threads ${Runtime.getRuntime().availableProcessors()} -vf [in]deflicker,dejudder[p0];[p0]vidstabdetect=shakiness=10:accuracy=15:result=transforms.trf[out] -f null -"

Expected behavior
the command mentioned above should be executed successfully, Therefore should get "transforms.trf" file as result.

Current behavior
This command is failed to be executed.
It says in logs "cannot open transform file transforms.trf"

Thanks in advance.

Can you try creating transforms.trf in a directory where you have write permission?

Additionally, you can take a look at VidStabTabFragment in Android test application. It uses vidstabdetect and vidstabtransform filters. It can help you to resolve this issue.

[SembaMax]

Thank you very much Taner.
As the example you mentioned above is quite clear, thanks again for sharing.
