vcsr
v0.6.0
用生锈写的视频联系表发电机。
此应用程序是VCSI的直接端口。全部荣誉归功于作者的算法和设计。
我正在学习Rust，在从事另一个项目时，我需要一个联系表生成器。现有发电机在安装过程中还需要其他一些工具，我想要一些可以插入并使用的东西。这个过程使我可以专注于语言的人体工程学，而不是算法。
我希望安装过程尽可能简单。从您的平台发行版中下载档案（也许将来某个时候Windows）。提取二进制文件，然后将其放在您的$PATH上。
需要安装ffmpeg和ffprobe 。
最简单的用法是除了输入文件以外，没有其他参数运行它。有关默认值，请参见下面的参数列表。
$ vcsr bbb_sunflower_2160p_60fps_normal.mp4
$ vcsr -h
vcsr 0.1.0
USAGE:
vcsr [FLAGS] [OPTIONS] <filenames>...
FLAGS:
-a, --accurate Make accurate captures. This capture mode is way slower than the default one but it
helps when capturing frames from HEVC videos.
-S, --actual-size Make thumbnails of actual size. In other words, thumbnails will have the actual 1:1
size of the video resolution.
--fast Fast mode. Just make a contact sheet as fast as possible, regardless of output image
quality. May mess up the terminal.
-h, --help Prints help information
--ignore-errors Ignore any error encountered while processing files recursively and continue to the
next file.
--no-overwrite Do not overwrite output file if it already exists, simply ignore this file and
continue processing other unprocessed files.
--no-shadow show dropshadow on frames
-r, --recursive Process every file in the specified directory recursively
-t, --show-timestamp display timestamp for each frame
--timestamp-border-mode Draw timestamp text with a border instead of the default rectangle.
-V, --version Prints version information
-v, --verbose display verbose messages
OPTIONS:
-A, --accurate-delay-seconds <accurate-delay-seconds>
Fast skip to N seconds before capture time, then do accurate capture (decodes N seconds of video before each
capture). This is used with accurate capture mode only.
--background-colour <background-colour>
Color of the timestamp background rectangle in hexadecimal, for example AABBCC [default: ffffff00]
--capture-alpha <capture-alpha>
Alpha channel value for the captures (transparency in range [0, 255]). Defaults to 255 (opaque) [default:
255]
--delay-percent <delay-percent>
do not capture frames in the first and last n percent of total time
--end-delay-percent <end-delay-percent>
do not capture frames in the last n percent of total time [default: 7]
--exclude-extensions <exclude-extensions>...
Do not process files that end with the given extensions.
--frame-type <frame-type>
Frame type passed to ffmpeg 'select=eq(pict_type,FRAME_TYPE)' filter. Should be one of ('I', 'B', 'P') or
the special type 'key' which will use the 'select=key' filter instead.
-g, --grid <grid>
display frames on a mxn grid (for example 4x5). The special value zero (as in 2x0 or 0x5 or 0x0) is only
allowed when combined with --interval or with --manual. Zero means that the component should be
automatically deduced based on other arguments passed. [default: 4x4]
--grid-horizontal-spacing <grid-horizontal-spacing>
number of pixels spacing captures horizontally [default: 15]
--grid-spacing <grid-spacing>
number of pixels spacing captures both vertically and horizontally
--grid-vertical-spacing <grid-vertical-spacing>
number of pixels spacing captures vertically [default: 15]
-f, --format <image-format>
Output image format. Can be any format supported by image-rs. For example 'png' or 'jpg'. [default:
jpg]
--interval <interval>
Capture frames at specified interval. Interval format is any string supported by `humantime`. For example
'5m', '3 minutes 5 seconds', '1 hour 15 min and 20 sec' etc.
-m, --manual <manual-timestamps>...
Space-separated list of frame timestamps to use, for example 1:11:11.111 2:22:22.222
--metadata-background-colour <metadata-background-colour>
Color of the metadata background in hexadecimal, for example AABBCC [default: b0cd7b0a]
--metadata-font <metadata-font> Path to TTF font used for metadata
--metadata-font-colour <metadata-font-colour>
Color of the metadata font in hexadecimal, for example AABBCC [default: ffffff00]
--metadata-font-size <metadata-font-size>
size of the font used for metadata [default: 32]
--metadata-horizontal-margin <metadata-horizontal-margin>
Horizontal margin (in pixels) in the metadata header. [default: 15]
--metadata-margin <metadata-margin>
Margin (in pixels) in the metadata header. [default: 15]
--metadata-position <metadata-position>
Position of the metadata header. [default: top] [possible values: Top, Bottom,
Hidden]
--metadata-vertical-margin <metadata-vertical-margin>
Vertical margin (in pixels) in the metadata header. [default: 10]
-s, --num-samples <num-samples> number of samples
-o, --output <output-path> save to output file
--start-delay-percent <start-delay-percent>
do not capture frames in the first n percent of total time [default: 7]
-O, --thumbnail-output-path <thumbnail-output-path>
Save thumbnail files to the specified output directory. If set, the thumbnail files will not be deleted
after successful creation of the contact sheet.
--timestamp-background-colour <timestamp-background-colour>
Color of the timestamp background rectangle in hexadecimal, for example AABBCC [default: 000000aa]
--timestamp-border-colour <timestamp-border-colour>
Color of the timestamp border in hexadecimal, for example AABBCC [default: 000000]
--timestamp-border-radius <timestamp-border-radius>
Draw timestamp text with a border instead of the default rectangle. [default: 1.0]
--timestamp-border-size <timestamp-border-size>
Size of the timestamp border in pixels (used only with --timestamp-border-mode). [default: 1]
--timestamp-font <timestamp-font> Path to TTF font used for timestamps
--timestamp-font-colour <timestamp-font-colour>
Color of the timestamp font in hexadecimal, for example AABBCC [default: ffffff]
--timestamp-font-size <timestamp-font-size>
size of the font used for timestamps [default: 12]
--timestamp-horizontal-margin <timestamp-horizontal-margin> [default: 5]
--timestamp-horizontal-padding <timestamp-horizontal-padding>
Horizontal padding (in pixels) for timestamps. [default: 3]
-T, --timestamp-position <timestamp-position>
Timestamp position. [default: se] [possible values: North, South, East,
West, NE, NW, SE, SW, Center]
--timestamp-vertical-margin <timestamp-vertical-margin>

--timestamp-vertical-padding <timestamp-vertical-padding>
V ertical padding (in pixels) for timestamps. [default: 1]
-w, --width <vcs-width>
