DirectShow filter-pipe for encoding video and audio streams and writing them to files using ffmpeg.exe

Overview

Pipe for ffmpeg uses the ffmpeg.exe external module to encode video and audio streams and write them to files. The encoding and file types depend on the ffmpeg.exe used. You can download it from https://www.ffmpeg.org/download.html.

Features

The path to the external ffmpeg module to be used must be specified.

The following encoders and file types were tested:

• video: mpeg2video, mpeg4, libxvid, libx264, libx265
• audio: copy, aac, ac3, mp2, libmp3lame, libopus, flac
• files: mp4, mov, avi, mkv, mpg

Additional parameters (bitrate and other encoding characteristics) can also be specified.

Optional use of common properties ("-y", "-loglevel", "-report", etc.) is allowed.

The tests used "FFmpeg 64-bit static Windows build from www.gyan.dev" (Version: 2024-10-24-git-153a6dc8fa-full_build-www.gyan.dev).

Specifications and description of user interfaces can be found in the .idl file in the \Idl folder of the filter installation directory.

• Input video streams are RGB or YUV, 8 or more bits, 4:2:0, 4:2:2 or 4:4:4 color spaces.
