But as mentioned previously, when outputting a single image -to does nothing and is ignored. Your FFmpeg version on macOS is new enough that it can use -to as an input option. You are using FFmpeg 3.4.6 which is too old to use -to as an input option. It has been updated to also work as an input file (declared before -i).
For older PCs, check foobar2000 v1.5 series on old versions page. The -to option was previously only an output option. This software uses code of FFmpeg licensed under the LGPLv2.1 and its source can be. You can use the alias -q:v instead of -qscale:v if you want. Get a screenshot at 22 hours 15 minutes 5 seconds but output lower quality: ffmpeg -y -ss 22:15:05 -i acb.mp4 -q:v 5 -frames:v 1 abc.jpeg
Same as above but gets a screenshot at 30 seconds: ffmpeg -y -ss 30 -i acb.mp4 -qscale:v 2 -frames:v 1 abc.jpeg -ss (start time offset) with a value of 0 is doing nothing, so you can remove that too.Įxample: ffmpeg -y -i acb.mp4 -qscale:v 2 -frames:v 1 abc.jpeg.A single image has no duration so -to is ignored anyway. You're outputting a single frame so you don't need to declare a duration stop time with -to.We slightly favor our own code to keep the dependencies on other libs low and to maximize code sharing between parts of FFmpeg. To achieve this we combine the best free software options available. The FFmpeg project tries to provide the best technically possible solution for developers of applications and end users alike. under a wide variety of build environments, machine architectures, and configurations. Hello everyone, as the title says Im trying to find a way to use ffmpeg to take a screenshot from lots of mkv files inside folders that are inside a main folder. It is also highly portable: FFmpeg compiles, runs, and passes our testing infrastructure FATE across Linux, Mac OS X, Microsoft Windows, the BSDs, Solaris, etc. No matter if they were designed by some standards committee, the community or a corporation. It supports the most obscure ancient formats up to the cutting edge. FFmpeg is the leading multimedia framework, able to decode, encode, transcode, mux, demux, stream, filter and play pretty much anything that humans and machines have created. A complete, cross-platform solution to record, convert and stream audio and video.
