Record SPICE session to MP4 video
Project description
spice-record
This is a simple utility for recording a SPICE sesion to MP4 video.
It uses libvirt to connect to the VMs, SpiceClientGLib
to access the graphics
device, and FFmpeg to encode MP4 videos.
Usage
usage: spice-record [-h] [--vcodec VCODEC]
[--loglevel {DEBUG,INFO,WARNING,ERROR,CRITICAL}]
[-r FRAMERATE] [-c LIBVIRT_URI] [-o FILENAME]
DOMAIN-NAME|ID|UUID
positional arguments:
DOMAIN-NAME|ID|UUID Machine to record
optional arguments:
-h, --help show this help message and exit
--vcodec VCODEC Set the output video codec (see "ffmpeg -encoders" for
choices)
--loglevel {DEBUG,INFO,WARNING,ERROR,CRITICAL}
Set the logging level (default=WARNING)
-r FRAMERATE, --framerate FRAMERATE
-c LIBVIRT_URI, --connect LIBVIRT_URI
Connect to hypervisor (e.g. qemu:///system)
-o FILENAME, --output FILENAME
Output filename (defaults to <domain-name>.mp4)
Requirements
- Python 3
libvirt-python
(notlibvirt-glib
)spice-glib
pygobject3
ffmpeg
If virt-manager
is installed on a modern distro (which has ported all of its
Python apps to Python 3), then everything should already be installed, aside
from ffmpeg
.
Notes
Currently, the spice server only supports a single client connection. When another connection is opened, the current one is disconnected. Thus, this utility is limited in its usability as it cannot record a user interacting with the VM, and only an automatic ongoing process. There is however, an experimental feature to enable multiple concurrent connections to a single spice server.
