video-editing

Currently i'm using MKVToolNix for my needs which is fine but i would prefer some CLI also. As far as i know ffmpeg supports chapters management. The ffmetadata format allows you to add chapters to a file. Have a look at https://ffmpeg.org/ffmpeg-formats.html#Metadata-1 for an example. cippu_lux Sorry maybe I'm not clear, and editing the answer I have messed up worst. I'm not English. Like Alex Zubkov I want add chapters to video with ffmpeg via cmd. The instruction in the page linked by MRousse don help me at all, but help me to solve 1st problem: Problem file was not in UTF-8.

I have the following command working in ffmpeg, which adds 1 second of a black frame to the beginning of the video. However, I lose the audio from the original video in the output video. How can I adjust the command to make sure the original audio stays with the final output, or better yet, there is 1 second of "blank" audio at the beginning so it matches the new output video. ffmpeg -i originalvideo -f lavfi -i color=c=black:s=1920x1080:r=25:sar=1/1 -filter_complex "[0:v] setpts=PTS-STARTPTS [main]; [1:v] trim=end=1,setpts=PTS-STARTPTS [pre]; [pre][main] concat=n=2:v=1:a=0 [out]" -map "[out]"

Background Over the past few days, I've worked on making a customizable, more updated version of a library for video trimming, here (based on this library ) The problem While for the most part, I've succeeded making it customizable and even converted all files into Kotlin, it had a major issue with the trimming itself.

But this way, I am getting memory issues and it crashes on the device. - (NSArray*)getVideoFramesFromMovieController:(MPMoviePlayerViewController*)mpMoviePlayerVC { NSLog(@"Getting frames from a video asset.")

I'm looking for a method to watermarking on a video with C#. As writing text on it. Image or text label... How can I do it? Thanks. amit singh baghel You can use Nreco Video Converter The Code will look like NReco.VideoConverter.FFMpegConverter wrap = new FFMpegConverter(); wrap.Invoke("-i D:\\input.mp4 -i D:\\inputImage.png -filter_complex \"overlay=10:10\" D:\\Output.mp4"); What about the great framework from AForge? http://www.aforgenet.com/ Brian H The great people at Splicer for .Net have already developed some C# code that does what you are looking for, but unfortunately I have heard

In my application I have fix composition render size of 1280 x 720. So if will import any portrait video then I have to show blur background with fill and aspect frame of video in centre. Same like this: https://www.youtube.com/watch?v=yCOrqUA0ws4 I achieved to play both videos using AVMtableComposition , but I don't know how to blur a particular background track.
