ustreamer-dump - Dump uStreamer's memory sink to file

ustreamer-dump [OPTIONS]

µStreamer-dump (ustreamer-dump) writes a local stream from ustreamer to a file or redirect it to other utilities (such as ffmpeg).

ustreamer requires at least the --sink option to operate.

To output ustreamers sink "test" to ffmpeg, and into a file called test.mp4:

ustreamer-dump \

--sink=test \ # Use ustreamer sink "test" 
--output - \ # Output to stdout
| ffmpeg -use_wallclock_as_timestamps 1 -i pipe: -c:v libx264 test.mp4

Memory sink ID. No default.
Timeout for the upcoming frame. Default: 1.
Filename to dump output to. Use '-' for stdout. Default: just consume the sink.
Format output as JSON. Required option --output. Default: disabled.

Verbosity level of messages from 0 (info) to 3 (debug). Enabling debugging messages can slow down the program. Available levels: 0 (info), 1 (performance), 2 (verbose), 3 (debug). Default: 0.
Enable performance messages (same as --log-level=1). Default: disabled.
Enable verbose messages and lower (same as --log-level=2). Default: disabled.
Enable debug messages and lower (same as --log-level=3). Default: disabled.
Force color logging. Default: colored if stderr is a TTY.
Disable color logging. Default: ditto.

Print this text and exit.
Print version and exit.
