Research direction

Start with the reported FFmpeg command and verify whether the built FFmpeg installation registers the transform_v1 filter. Compare the build procedure with the installed FFmpeg configuration; done means transform_v1 is recognized and the command processes input.mp4 without the filter-initialization error.
