Video output
| Module: image | |
|---|---|
| Type | Video output |
| First VLC version | 0.8.2 |
| Last VLC version | 0.9.10 |
| Operating system(s) | all |
| Description | Outputs the video images to files |
| Shortcut(s) | - |
In VLC 1.0.0 the image video output was rewritten into a video-filter named scene, and the old image video output was removed.
Trivia: the help text was never changed after this commitdiff changed the default values of unsigned integers --image-out-width and --image-out-height from -1 to 0—there was little point in fixing the help text for a deprecated module in software not yet publicly released! The coding error is absent from the current module, scene.
Option aliases --image-width for --image-out-width and --image-height for --image-out-height were deprecated in 0.9.0.
Options
- image-out-format <string> {png,jpeg} : Format of the output images default value: png
- image-out-width <integer> : You can enforce the image width. By default VLC will adapt to the video characteristics default value: 0
- image-out-height <integer> : You can enforce the image height. By default VLC will adapt to the video characteristics default value: 0
- image-out-ratio <integer> : Ratio of images to record. 3 means that one image out of three is recorded default value: 3
- image-out-prefix <string> : Prefix of the output images filenames. Output filenames will have the "prefixNUMBER.format" form. Starting with VLC 0.9.0 you can also use format time and meta variables default value: img
- image-out-replace <boolean> : Always write to the same file instead of creating one file per image. In this case, the number is not appended to the filename default value: disabled
Demux
| Module: image | |
|---|---|
| Type | Access demux |
| First VLC version | - |
| Last VLC version | - |
| Operating system(s) | all |
| Description | Image demuxer |
| Shortcut(s) | - |
Options
- image-id <integer> : Set the ID of the elementary stream default value: -1
- image-group <integer> : Set the group of the elementary stream default value: 0
- image-decode <boolean> : Decode at the demuxer stage default value: enabled
- image-chroma <string> : If non empty and image-decode is true, the image will be converted to the specified chroma default value: ""
- image-duration <float> : Duration in seconds before simulating an end of file. A negative value means an unlimited play time default value: 10
- image-fps <string> : Frame rate of the elementary stream produced default value: 10/1
- image-realtime <boolean> : Use real-time mode suitable for being used as a master input and real-time input slaves default value: disabled
