In this example each image will have a duration of 5 seconds (the inverse of 1/5 frames per second). If the input -framerate is higher than the output -r then ffmpeg will drop frames to reach your desired output frame rate. If the input -framerate is lower than the output -r then ffmpeg will duplicate frames to reach your desired output frame rate. This is useful if your player cannot handle a non-standard frame rate. If you want the input and output frame rates to be the same, then just declare an input -framerate and the output will inherit the same value (meaning you can omit the -r).īy using a separate frame rate for the input and output you can control the duration at which each input is displayed and tell ffmpeg the frame rate you want for the output file. The output frame rate for the video stream by setting -r after -i or by using the fps filter. MediaCodec API provides factory methods that allow you to create an instance of MediaCodec. The default for reading inputs is -framerate 25 which will be set if no -framerate is specified. Set input frame rate with the -framerate input option (before -i). So I guess my problem is two-fold-the syntax to use and if there is some bug in ffmpeg Media Encoder for Android that will not allow me to input that command.You can specify two frame rates: input and output. I type up the command in a text editor and if it has a semicolon in it, it won't paste the whole command. I am using ffmpeg Media Encoder for Android and it will not let me use semicolons! I try to type one in and it doesn't show up. One major issue with the syntax is that the command uses semicolons. I have googled up tutorials such as this one, but I haven't been able to get it to work. ffmpeg just takes the size of the first image, 556×494, and then converts all others to that exact size, breaking their aspect ratio. I had no problem cropping the section out of the lower resolution file, but I can't figure out how to overlay it onto the higher resolution one. What I would like to do just to see if it looks better is to take the matching 120x80 square from the lower resolution video and resize it and overlay it over the logo on the higher resolution file. FFmpeg Batch AV Converter is a free universal audio and video encoder.

I know how to use a mask file and removelogo to blur the logo out on the higher resolution file, but it still looks messy with the blurring. Android SDK API iOS SDK API macOS SDK API C++ API for All Platforms Real-time. What I want to do: I have two copies of a video file-one is 1280x720 but has a logo approx. Okay, I am pretty new to using ffmpeg but not new to video editing itself-I have only recently reluctantly began stepping away from VirtualDub because it doesn't play well with the newest video formats.
