ffmpeg-overlay.py - ffmpeg wrapper for gamecontroller overlays. =============================================================== ## Dependencies - Needs Python 3, tested with Python 3.5.1 - Needs the `cairocffi` python module. - Expects `unpremultiply` to be in the `$PATH`. - For recording the events, use the `jstest` program. ### Install cairocffi Check your repository for cairocffi or install it using pip: pip install --user cairocffi # omit --user for system-wide installation ### Building unpremultiply cc -Wall -O2 -o unpremultiply unpremultiply.c ffmpeg-overlay.py expects unpremultiply to be in the current PATH. # assuming unpremultiply is in the current # directory, like after the build step export PATH=$PWD:$PATH ## Usage While recording the video, record the events using the jstest program: stdbuf -oL jstest --event "/dev/input/js1" >events.jse Change to your js device accordingly. Use ctrl-c to stop recording. `stdbuf` is used here to prevent the last few events from being dropped when the program is killed. After recording, use the `ffmpeg-overlay.py` script to re-encode the video with overlay: ffmpeg-overlay.py -e events.jse -t xboxdrv --pos 1,.8 -- ffmpeg -i recorded-video.mkv '{overlay}' -c:v libx2*** -crf 23 -y output-video.mkv The basic usage here is ffmpeg-overlay.py -e [options] -- The special argument `{overlay}` is replaced with the options for ffmpeg to receive the generated overlay, including a video filter. This value must follow the first input file, because the filter expects the first input to be the main video and the second input to be the overlay. ### Controller type, layout and theme Specify your controller type with the `-t` option. If there is no match for your controller, see [Advanced configuration](https://github.com/ferreum/ffmpeg-overlay/blob/master/#advanced-configuration). Use `-l` and `-T` respectively to specify layout and theme. ### Syncing The events and the video will probably be offset by a certain time. For this there exists the `-d` option to delay the events. # delay all events by 0.3 seconds ffmpeg-overlay.py -e events.jse -d 0.3 ... # make all events appear 0.2 seconds earlier ffmpeg-overlay.py -e events.jse -d -0.2 ... Notice that the absolute times recorded by jstest do not matter, as all times are used relative to the time of the first event. ### Cut the video at the start To start the video (and the overlay) at a different point, use the `-s` option. There exists another special value for the ffmpeg commandline to aid with this: `{ss}` is replaced with the same value given to `-s` such that ffmpeg's `-ss` option understands it. ffmpeg-overlay.py -e events.jse -d 0.3 -s 15.3 -- ffmpeg -ss '{ss}' -i recorded-video.mkv '{overlay}' -c:v libx2*** -crf 23 -y output-video.mkv This starts the video at 15.3 seconds with events delayed by 0.3 seconds. Notice that the `-ss` option needs to be specified before the main video file. ## Advanced configuration ffmpeg-overlay.py sources the file `$XDG_CONFIG_HOME/ffmpeg-overlay/config.py` if it exists. Custom controller types, layouts and themes can be specified here. See `defaults.py` for examples.
