Throw new NotImplementedException("ConvertMediaExtractorSampleFlagsToMediaCodecBufferFlags") Īs far as I can tell is, it takes every frame of the video at the point of the first cut and put every following frame into a buffer until the point of the end cut.

I translated it to C# and so far it works flawlessly: public string Trim(int startMs, int endMs, string inputPath) Now when using the endpoint /audio/redact, your redacted audio will be uploaded to s3 and changes will be persisted on the client.I did indeed find an android java example on stackoverflow. This click event will now make a call to our custom server where the redaction of the video will take place with ffmpeg. In this example, we used update element to overload the click event of the Redact buttons. FFMpeg.PosterWithAudio (inputPath, inputAudioPath, outputPath) // or var image Image.FromFile (inputImagePath) image.AddAudio (inputAudioPath, outputPath) Other available arguments could be found in FFMpegCore.Arguments namespace. Below is an example of how to integrate the server with WebViewer Audio. Combine an image with audio file, for youtube or similar platforms.
