This is on a Raspberry Pi 4, if it matters. [mmal: mmal_port_enable: failed to enable port vc.ril.hvs:out:0(OPQV)(0x941fbc20) (EINVAL) [mmal: mmal_vc_port_enable: failed to enable port vc.ril.hvs:out:0(OPQV): EINVAL My best guess, according to the VLC docs I've discovered, is something like this: vlc -video-filter=croppadd -croppadd-croptop=75 -croppadd-cropbottom=25 -f \?v\=eE6VVJ3hvvīut it results in recurring error messages: mmal_codec filter error: Failed to enable output port vc.ril.hvs:out:0(OPQV) (status=3 EINVAL) I'm able to crop via the GUI, and I can play the un-cropped video using the command line, but I'm unable to find the correct settings to play cropped from the command line. Some livestreams have titles or captions I don't care for, and thus I'd like to crop / scale the video. I'm trying to play YouTube livestreams from the command line (for use as video backgrounds during live sessions). Before that i was using FFmpeg to do cutting and cropping which is really a powerful tool for anything related to editing and converting videos but for simple tasks such as cropping and cutting you can just use VLC. Click Media on the top left and then Open file. Check the list above to make sure your file is compatible and open it in one of three ways: Drag and drop the file directly into the VLC media player window. I just wanted to share with you this trick i’ve discovered recently which is simple and requires less time. Open the file Next, you’ll need to open the video file you want to trim. Don’t worry if you are a Mac user because VLC also allows you to crop video in desired crop ratio on Mac. Thanks for reading and i hope this is was helpful for you. You can also use VLC under Windows to cut or crop your videos in the same way i’ve shown here. Next choose the Input/Codecs tab and then look for Record directory and filename and browse for your folderĪfter that you just hit save to confirm you change. You can change the default output directory by simply going to Tools > Preferences Under window settings (i'm guessing the name, since mine is in another language), there should be a video crop setting. Now go to your videos folder to find your video. On vlc's preferences, at the bottom, set show settings to all and on the list on the left scroll down to video. So you simply start playing the video and whenever you are at some point where you want to cut the video you just press the red record button and let the player continues playing the video until you arrive at the point where you want to stop cutting and press the red button again to stop. This will preserve your original video and record just the chunk you want which will be available on your videos folder. The first button is a recording button that you can use to record a piece of your video when playing it. Now you can see some new controls in your player just above the playing controls Select the View Menu then click on the advanced control option Go ahead and open up the video file that you want to cut using VLC player. The process is very simple and straightforward but you need a bit of configuration first. But it can be used for more than just playing videos for tasks like cutting and trimming videos into pieces so how you can use VLC to cut or trim a video ? VLC is a powerful media player that’s available on both Linux and Windows. You can usually do such tasks on Linux systems like Debian or Ubuntu using command line tools such as the powerful and famous FFmpeg but the task can be daunting and not everyone feels very comfortable using these advanced tools so what’s the alternative ?Ī simple, user friendly and cross platform alternative is VLC. Ever wanted to cut videos into pieces or chunks and found out that the process can be complex especially on Linux systems.
