Puppy Linux Discussion Forum

EDITThis utility is now replaced by a similar - but better - version which handles mp4, avi, mov and flv etc too. The new version also handles spaces in filenames.
Please see: viewtopic.php?t=12215

This is a small utility I use for cropping a portion out of an MP4 video (such as the videos produced by my dashcam).

(The "cropped" portion is the part of the video that I want to keep - and is saved with a name based on the original name combined with a timestamp in order to prevent overwriting of files. The other parts of the video are ignored and the original file is unchanged)

Just place the utility wherever you want it (I use /root), remove the false .gz suffix, then make executable and click to run it.

(It uses ffmpeg to do the cropping so should work in a variety of pups. I use it mostly in Fossapup)
NOTE: modern pups that use gtk3 will need to use the "bookwormpup" version added further down below.

Tested. Did not create a result in BKWP64 v1006. No matter the duration.

Thanks for the testing Clarity. I dont know what causes this but my guess is gtk version maybe.
I will set up a Bookworm pup and do some testing.
Cheers!

I have now added a version for Bookwormpup in the first post. I assume it is also possibly suitable for other pups that are using gtk3.
@Clarity i would be keen for you to retest if you have time please. (Thanks for the complete and accurate bug report - very helpful)
Cheers!

greengeek,

This worked good enough for me. Which video player (MPV here) were you sampling with?

+1

Loaded in my-applications/bin. This utility can launch from ROX (via click) or from a terminal.

Question
In your future, could it be opened in a terminal by adding the video filepath? For example
mp4cropper /mnt/home/media/1.mp4

It works very well and very fast as it is.

Hi Semme - good to hear from you. Which pup were you using for the test please? My usual daily driver is a version of Ozsouth's Fossa 9.5 Mid which uses mplayer, but I have now also tested it with BookwormPup (mpv) and rockedge's latest Fossa 9.6 CE which also uses mpv.
(I think there may be a problem with the mpv in bookworm but I have only just started testing it so too early to confirm...)

Very good question and I am afraid I do not know the answer.
I will do some research about how to achieve that.

EDIT : I just tried this and it seems to work:
Placed the mp4cropper_bookwormpup utility into /usr/local/bin and opened a terminal and ran the following:
mp4cropper_bookwormpup /root/test.mp4

....and it opens up the gui as normal.

Does this work for you? Or did I misunderstand your question?

EDIT2:
No i guess what you meant was - is it possible to pass all the parameters to the utility ex cli.
eg: mp4cropper /mnt/home/media/1.mp4 x y - where x is start_seconds and y is duration_seconds.
Unfortunately I don't know how that is done (gut feeling that it may be something to do with ncurses) - but will do more researching)

EDIT3:
I have worked out how to "collect" the variables passed by the user from the CLI to the script - but havent worked out yet how to default them into the gtkdialog gui display. Workin' on it. I may be some time...

Thank you gg, Mate. As for my driver I'm still running philb's, rock-solid Fossapup!

Hi @Clarity - I have decided not to integrate passsing of cli variables into the gtk gui just yet (as I need to find more info first).

However - if you have time please try this similar script I have written ("mp4crop")
(It is not a gtkdialog gui - just a cli only version of the same conversion).

Usage:
- Place "mp4crop" in PATH (i used /usr/local/bin but your my-applications-bin method will work i assume??)
- in terminal type the following:
mp4crop /root/test.mp4 x y

(where x= startseconds and y=durationseconds)
(and obviously change the filename to match yours)

Delete false .gz suffix, make executable, and place in PATH

Works

I like and continue to use the MP4Cropper. Again THANKS!

I offer this ONLY for information (entertainment for some): AND it is NO WAY is a suggestion.

Enjoy ===> 2024 Editing in Linux

I like this!

Using the command line version.

For a 3min video the crop was nearly instantaneous.

This utility has been replaced by a better one (vidxtractor) which can be found here:
viewtopic.php?t=12215

Two main reasons for replacement:
1) mp4cropper could not handle spaces in filenames (new utility can)
2) The term "cropping" a video was a bit of a misnomer. "Cropping" really should refer to the changing of resolution or aspect ratio of each video frame - rather than extacting a portion of the video at original resolution. (ffmpeg CAN handle frame cropping but my utility was not intended for that so the name was deceptive)

If there are any questions re mp4cropper I will still attempt to answer - but I recommend vidxtractor instead, so I have marked this thread superceeded.
