Above commandgenerate ffmpeg command like this:įfmpeg.exe -n -threads 12 -i "C:\Users\tzmuda\Source\Xabe.FFmpeg\\bin\Debug\netcoreapp2.0\Resources\SampleVideo_360x240_1mb.mkv" -i The concat filter does not allow -vcodec copy and therefore the additional time required to re-encode and the additional server load this entails is not acceptable. Streams in exchange for flexibility of passing files. mencoder instead of ffmpeg to join or concatenate video files with different audio streams The problem for me is that Ihad two videos with different types. Implementation of this method is a bit complicated (it is available on our GitHub repository) and it doesn't allow topass any additional arguments or manipulate particular Make text file containing: file 1.mp4 file 2.mp4 Run ffmpeg: ffmpeg -f concat -i input.txt -c copy output. This method does not work for many formats, including MP4, due to the nature of these formats and the simplistic concatenation performed by this method. ffmpeg -i concat:input1input2 -codec copy output.mkv. ![]() IConversionResult result = await Conversion.Concatenate(output, firstFile, secondFile) concat protocol Use this method with formats that support file-level concatenation (MPEG-1, MPEG-2 PS, DV). Full implementation is available on GitHub.Īll of concatenation options can be used in Xabe.FFmpeg by Conversion.Start(string) which allows user to pass arguments directly into FFmpeg. Too,but we adapt some features to be more elastic. Concatenate mp4 Files of Different Codecs, resolutions 3. However Concat protocol was easy to use but supports only MPEG based files. Followed are three methods to help you concatenate videos fast in FFmpeg, together with the first part with detailed guide. ![]() Concat demuxer requires that all files must have the same streams (same codes, time base, etc.)Īnd we need somethingmore flexible. Once upon time we hadto deal with that feature.ĭue to limits of each concatenation method we implemented it by "filter". There are a lot of questions and articles how to concatenate multiple videos into one with FFmpeg. ![]()
