Based on libav and the great LTC library of Robin Gareus, I wrote a small tool to simplify the synchronization of video files with audio: https://github.com/gisogrimm/ltcvideosplit If you connect an LTC signal (e.g., as generated by Ardour) with the audio input of any low-budget video camera, the video material of the camera can be aligned to the audio material played/recorded along with the LTC time-line (e.g., in Ardour). Essentially, this tool reports video- and LTC-frame number whenever they drift apart or the LTC signal starts. My use cases: - research: record videos for motion analysis which are time-aligned to sound events (with multiple cameras) - music videos: record videos to existing audio material with multiple cameras or multiple takes Maybe this tiny tool is useful for someone. Thanks to Robin for LTC tools and LTC support in Ardour! -- Giso _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
