Class ConversionSource(builtins.tuple)

ConversionSource(src, srcfmt, start_s, end_s)

ConversionSource.end_s: Alias for field number 3

ConversionSource.src: Alias for field number 0

ConversionSource.srcfmt: Alias for field number 1

ConversionSource.start_s: Alias for field number 2

convert(*srcs, dstpath: str, doit=True, dstfmt=None, ffmpeg_exe=None, fstags: Optional[cs.fstags.FSTags] = <function <lambda> at 0x10a3b6950>, conversions=None, metadata: Optional[dict] = None, timespans=(), overwrite=False, acodec=None, vcodec=None, extra_opts=None) -> List[str]

Transcode video to dstpath in FFMPEG compatible dstfmt.

ffmpeg_docker(*ffmpeg_args: Iterable[str], docker_run_opts: Union[List[str], Mapping, NoneType] = None, doit: Optional[bool] = None, quiet: Optional[bool] = None, ffmpeg_exe: Optional[str] = None, docker_exe: Optional[str] = None, image: Optional[str] = None, output_hostdir: Optional[str] = None) -> Optional[subprocess.CompletedProcess]

Invoke ffmpeg using docker.

Class FFmpegSource

A representation of an ffmpeg input source.

FFmpegSource.add_as_input(self, ff): Add as an input to ff. Return None if self.source is a pathname, otherwise return the file descriptor of the data source.

Note: because we rely on ff.input('pipe:') for nonpathnames, you can only use a nonpathname FFmpegSource for one of the inputs. This is not checked.

FFmpegSource.promote(source): Promote source to an FFmpegSource.

ffprobe(input_file, *, doit=True, ffprobe_exe='ffprobe', quiet=False)

Run ffprobe -print_format json on input_file, return format, stream, program and chapter information as an AttrableMapping (a dict subclass).

main_ffmpeg_docker(argv=None)

The ffm[peg-docker command line implementation.

Class MetaData(cs.tagset.TagSet)

Object containing fields which may be supplied to ffmpeg's -metadata option.

MetaData.__init__(self, format, **kw): pylint: disable=redefined-builtin

MetaData.options(self): Compute the FFmpeg -metadata option strings and return as a list.

Release Log

Release 20241122: Honour the $FFMPEG_DOCKER_IMAGE environment variable.

Release 20240519: ffmpeg_docker: set DockerRun.output_hostdir from the output file dirname.

Release 20240316.1: DISTINFO fix.

Release 20240316: Fixed release upload artifacts.

Release 20240201:

• New $FFMPEG_EXE envvar.
• convert: use $FFMPEG_EXE, return the ffmpeg argv.
• convert: include the media type in DEFAULT_CONVERSIONS, refactor the choice of codec conversion.
• convert: supply dummy results if doit is false - could do with some finesse.
• ffmpeg_docker: use DockerRun.{add_input,add_output}.
• New main_ffmpeg_docker to support the ffmpeg-docker command, add ffmpeg-docker to DISTINFO scripts.

Release 20231202: Initial PyPI release.
