Image writer plugin.
bg_plugin_common_t bg_image_writer_plugin_s::common |
Infos and functions common to all plugin types.
const char* bg_image_writer_plugin_s::extensions |
File extensions (space separated)
void(* bg_image_writer_plugin_s::set_callbacks)(void *priv, bg_iw_callbacks_t *cb) |
Set callbacks.
priv | The handle returned by the create() method |
cb | Callback structure |
int(* bg_image_writer_plugin_s::write_header)(void *priv, const char *filename, gavl_video_format_t *format, const gavl_metadata_t *m) |
Write the file header.
priv | The handle returned by the create() method |
format | Video format |
The format will be changed to the nearest format, which is supported by the plugin. To convert the source format to the output format, use a gavl_video_converter_t
int(* bg_image_writer_plugin_s::write_image)(void *priv, gavl_video_frame_t *frame) |
Write the image.
priv | The handle returned by the create() method |
frame | The frame containing the image |
After writing the image the plugin is cleaned up, so write_header() can be called again after that. If frame is NULL, no image is read, and the plugin is reset.
