video grabber with time line in video

[Tomasz CEDRO]

For quick testing I use my favorite media player VLC - it opens all
sorts of devices and file formats (even broken ones), can stream
online, can transcode, works everywhere even from console or web :-)

For streaming or recording live events even with multiple sources with
real-time mixer control watermarks and scenes OBS is the best known
utility:

If you need anything smaller scripted probably you could use gstreamer
of ffmpeg?

ps/2: For anyone in need to grab some old analog stuff from VHS or
retro computers the tiny inexpensive VGB300 from April Inc is UVC
compatible and works out of the box on FreeBSD:
