Until the frame is reached, then it shows this: : frame= 1 fps=0.0 q=2.0 Lsize=N/A time=00:00:00.04 bitrate=N/A speed=0.00151x In my log it will show this repeatedly: : frame= 0 fps=0.0 q=0.0 size=N/A time=00:00:00.00 bitrate=N/A speed= 0x The command works perfectly BUT it takes forever to complete. #Image processing export to ffmpeg command android#It is a android application so that is way it is in a string array. ffmpeg -hwaccel auto -i in.jpg -vf scale200:200 -swsflags lanczos out.png. You can try the below command and see if there's a speed or GPU utilization difference. It will then increment that number by one and if the image exists, it will be added to the sequence. I don't think the PNG encoder can use the GPU, and neither does the JPEG decoder. This will search for the image with the lowest digit and sets that as the starting image. The createLoop package can be used as follows in your sketch, where you’ll have to add a new script tag in the html file, and a single line in the setup function of your sketch.In my application the user can seek to a specific position (media.currentPosition), then press the save button, the image will then be exported, here is my ffmpeg command I'm using to achieve this: "-i",Video.mp4,"-filter_complex","scale2ref=iw:ih colorchannelmixer=aa=0.7 overlay","-map","","-ss",GetPositionInVideo,"-vframes","1","-q:v","2", "-preset", "ultrafast",directoryToStore+"/"+"Image.jpg"} ffmpeg -framerate 1 -i happyd.jpg -c:v libx264 -r 30 output.mp4 The above command takes an input of images, -i happyd.jpg. Since a GIF is merely a concatenation of frames, you could then load that GIF into your editor of choice to make some changes, or manipulate it with a command line tool like FFMPEG. This one doesn’t give you the individual frames per se, but directly creates a GIF underneath the P5JS canvas, which you can then save to your device. These commands should be the same on Windows. tar file that holds all the frames that you require to make your GIF. ImageMagick allows various kinds of image-processing functionality (as shown below) from the command-line. After running your sketch and setting the parameters in the code, you’ll receive a. Jeff’s template is simply fantastic and everything you basically need. Saving frames with CCaptureĬCapture is a javascript library for capturing canvas based animations, such as the P5JS canvas for example. However it takes a tad bit longer that way. I’ve tried with chrome and microsoft edge and in both cases they tried to throttle these quick downloads, making it such that many frames were missing in the final output folder.Īfter some help from the birbs nest discord it seems that setting the FPS via the frameRate() command to something low like 1-5 frames per second, makes it much more consistent and reliable. #Image processing export to ffmpeg command full#In other words, running your sketch at full 50-60FPS, and trying to save each individual frame in quick succession might be taxing on your browser. Golan Levin’s template works well, however you might have to rate limit the frame rate of your sketches for this to work well. If you're lazy like me, you can use the createLoop package, which can be found here.For this one, Jeff++ has made a fantastic loop template and in depth explanation for this which can be found here and an in depth explanation here Golan Levin has a fantastic loop template for this purpose (among others) Making use of the saveCanvas function.In p5js it’s a little bit trickier, but we have a couple of options here, in no particular order: Notice that in java it will implicitely cast the counter integer to a string. We can do this with the help of a counter that gets incremented every draw loop: int counter = 0 Obviously, we’ll have to pass a different name for each frame, otherwise we would be overwriting the same file over and over again. Analyzes the video and then stabilizes it using the ffmpeg vidstab filter. We can simply call the save(“frame.png”) function in the draw loop, and an image will appear in the corresponding sketch folder. In processing, saving an indivdiual frame is very straight forward. We’ll tackle these two steps, one at a time! In Processing: Generally the first step is to extract individual frames from we’ll first have to extract and save individual frames from our animation and then convert them into a complete GIF. #Image processing export to ffmpeg command series#Exporting your Sketches as a Series of Individual Frames But there are a number of tools and tricks that can make our life easier in this regard, which we’ll go over in this blog post.Īctually, the really hard part is making your GIFs smaller than 15mb. Making GIFs out of your creative coding sketches can be tricky and tedious. Wait a second… how do you actually do that? You spent hours coding up a nice sketch in P5JS or Processing, ironed out those last few bugs, and made it run smoothly at a crispy 50FPS… but now what?
