Utility to encode quick webms using Unix sockets to queue the encoding parameters whenever it is executed
Project description
PureWebM
Originally written for PureMPV, with this utility it is possible to encode webms from a given input, according to a restricted file size or a default CRF (Constant Rate Factor). If the utility is called whilst encoding, additional webm parameters will be put in a queue using a Unix socket for IPC.
Usage
It is possible to request usage instructions through the --help
or -h
argument option flags when the program is installed:
$ purewebm --help
usage: purewebm [-h] [--version] [--output OUTPUT] [--encoder ENCODER] [--start_time START_TIME]
[--stop_time STOP_TIME] [--lavfi LAVFI] [--size_limit SIZE_LIMIT] [--crf CRF]
[--extra_params EXTRA_PARAMS]
input [input ...]
Utility to encode quick webms with ffmpeg
positional arguments:
input the input file(s) to encode (NOTE: these are only for a single output file; to encode different
files run this program multiple times, the files will be queued in the main process using a
Unix socket)
options:
-h, --help show this help message and exit
--version, -v show program's version number and exit
--output OUTPUT, -o OUTPUT
the output file, if not set, the filename will be generated using the filename of the input
file plus a short MD5 hash and saved in $HOME/Videos/PureWebM
--encoder ENCODER, -e ENCODER
the encoder to use (default is libvpx-vp9)
--start_time START_TIME, -ss START_TIME
the start time offset (same as ffmpeg's -ss)
--stop_time STOP_TIME, -to STOP_TIME
the stop time (same as ffmpeg's -to)
--lavfi LAVFI, -lavfi LAVFI
the set of filters to pass to ffmpeg
--size_limit SIZE_LIMIT, -sl SIZE_LIMIT
the size limit of the output file in megabytes, use 0 for no limit (default is 3)
--crf CRF, -crf CRF the crf to use (default is 24)
--extra_params EXTRA_PARAMS, -ep EXTRA_PARAMS
the extra parameters to pass to ffmpeg, these will be appended making it possible to override
some defaults
Installation
It can be installed using pip:
$ pip install purewebm
or
$ git clone https://github.com/4ndrs/PureWebM.git
$ cd PureWebM
$ pip install .
