To take a list of images that are padded with zeros ( pic0001.png, pic0002.png…. I have noticed that different versions of ffmpeg will produce different output file sizes, so your mileage may vary. When using ffmpeg to compress a video, I recommend using the libx264 codec, from experience it has given me excellent quality for small video sizes.

Streams in exchange for flexibility of passing files. 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 IConversionResult result = await Conversion.Concatenate(output, firstFile, secondFile) 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. However Concat protocol was easy to use but supports only MPEG based files. 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.
