Here is what I do, nothing special: ffmpeg -i -f gif -y frame_%09d.gifįfmpeg version N-54643-g15cee5e Copyright (c) 2000-2013 the FFmpeg developersĬonfiguration: -enable-gpl -enable-version3 -disable-w32threads -enable-avisynth -enable-bzlib -enable-fontconfig -enable-frei0r -enable-gnu Of course, I could save PNGs and use ImageMagic's convert utility to transform them to GIFs, but I don't want any additional invocation overhead because I'm dealing with live streams and going to crunch large amounts of data. But when I set output file to something like frame%09d.gif ffmpeg tends to create an animation (and stores it exactly as frame%09d.gif).
Right now, the GIF is well generated (with the palette) in memory using FFMPEG C API, the only problem is that the GIF is way too fast and not at the right framerate.The question is simple: I don't want ffmpeg to create an animated GIF from given video stream, I want separate frames, each in GIF format. So I get a bit confused with all the place where we have to set the framerate. I would like to have a FPS=12, so should I define them as follow ? AVRational time_base = AVRational Width, height, in_fmt, time_base.num, time_n, Into the init_filters(.) method, I don't understand the time_base and pixel_aspect variables of the argument structure: snprintf(args, sizeof(args), This work pretty well, but I have issue with the GIF framerate. I started from this topic and I just replaced the video decoder part with a conversion of my image in memory to an AVFrame. I have an image processing pipeline, and I have images in memory that I convert into AVFrame and I try to create a GIF with those.
