Hi I wrote the below simple code to merge two video files, it's working. But I wanna track the merging task percentage (or something that shows the progress), so I could show it using a progress bar. How to track the progress? Thanks.

textBox_taskMsg.Text = "Task is being performed.. This may take some time.";

string[] files = { textBox_Source1.Text, textBox_Source2.Text }; // Vids to be merged
string output = textBox_Source1.Text + "_merged.mp4"; // Output vid name
var conversion = await FFmpeg.Conversions.FromSnippet.Concatenate(output, files); // Merge
await conversion.Start();

// SHOW MERGING PROGRESS

textBox_taskMsg.Text = "Merge Complete.";

Thanks. The two files I'm trying to merge are around 30MB each. I'm actually not that familiar with working videos in C#, just playing around and testing here. Anyways, a video merger like Wondershare would take less than 5 mins to do it, and the resulting video would be less than 100MB. I'm not sure how to properly do that.

Hi. I tried to merge two videos into one using Splicer library. When I ran the code (below), the code got non-responsive, so after awhile I stopped the code from executing. The resulting file (which was created by the code while it has became non-responsive) was over 11GB. I'm not sure how to fix that. Could anyone guide me please? Thanks.

--------
//Create a string array to store file paths
string[] filepaths = new string[10];
filepaths.SetValue(textBox_Source1.Text, 0);
filepaths.SetValue(textBox_Source2.Text, 1);
//Call the video merging function
MergeVideos(filepaths, filepaths[0] + "_merged");

using (ITimeline timeline = new DefaultTimeline())
{
IGroup group = timeline.AddVideoGroup(32, 720, 576); // Set bitrate, width, height

var firstClip = group.AddTrack().AddVideo(videoPaths\[0\]);
var secondClip = group.AddTrack().AddVideo(videoPaths\[1\], firstClip.Duration /\* offset \*/);

using (AviFileRenderer renderer = new AviFileRenderer(timeline, outputFilePath))
{
    renderer.Render();
}
