var ( // DefaultConfig is the default configuration if not specified. DefaultConfig = &Config{ Binary: "ffmpeg", Args: []string{ "-y", "-safe", "0", "-f", "concat", "-i", "", "-c:a", "copy", "-c:d", "copy", "-c:v", "libx264", "-vf", "scale=1920:1080", "-copy_unknown", "-map_metadata", "0", "-movflags", "use_metadata_tags", "-map", "0:v", "-map", "0:a", "-map", "0:m:handler_name:\tGoPro TCD", "-map", "0:m:handler_name:\tGoPro MET", "-map", "0:m:handler_name:\tGoPro SOS", }, SourceDir: ".", OutputTemplate: "{{.Name}}-JOINED{{.Ext}}", LogLevel: "warn", } )
Functions ¶
func DefaultHandler ¶
DefaultHandler is the default Handler function which runs ffmpeg wiring up Stdout and Stderr.
Types ¶
type Config ¶
type Config struct {
LogLevel string
SourceDir string
Binary string
Args []string
SkipNames []string
OutputTemplate string
OutputDir string
Overwrite bool
// contains filtered or unexported fields
}
Config represents a GoPro video processing configuration.
type File ¶
type File struct {
// Name is the raw filename.
Name string
// Chapter is the chapter of the video typically a two character number.
// Depending on generation the first chapter may be 00 or 01.
Chapter string
// Index is video index of the video typically a 4 character number.
Index string
}
File represents a GoPro video file.
type FileSlice ¶
type FileSlice []File
FileSlice attaches the methods of sort.Interface to []File, sorting in increasing chapter order.
type Log ¶
type Log interface {
Println(v ...interface{})
}
Log is implemented by types which can act as Processor logger.
type Matcher ¶
type Matcher struct {
// contains filtered or unexported fields
}
Matcher provides the ability to identify GoPro video files.
func NewMatcher ¶
NewMatcher returns a fully initialised Matcher.
func NewMatcherMust ¶
NewMatcherMust returns a fully initialised Matcher and panics if any error occurs.
type Option ¶
Option represents an configuration option for Processor.
func CfgFile ¶
CfgFile loads the config from file for the Processor. Either CfgFile or Cfg must be specified.
type OutputFile ¶
type OutputFile struct {
// Name excluding extension.
Name string
// Extension including the dot.
Ext string
}
OutputFile represents the template used for output file processing.
type Processor ¶
type Processor struct {
// contains filtered or unexported fields
}
Processor provides the ability to process GoPro video files. If it finds chaptered files they are joined during processing.
func NewProcessor ¶
NewProcessor creates and returns a configured Processor.
