Description:

This module encodes the JPEG Pleno LF Dataset using the JPEG Pleno Model (JPLM). This implementation is for JPEG Pleno CE 16.

get_data_from_preffix(file_lines, preffix)[source]

Extracts the value from a log line that starts with the given prefix.

Parameters:

  • file_lines (List[str]) – List of lines from the log file

  • preffix (str) – Prefix string to search for at the start of lines

Returns:

The value after the prefix, or empty string if not found

Return type:

str

clone_and_build_repo(codec_configuration, global_configuration, fulldocker=None)[source]

Clones and builds the codec repository if configured.

If repository is present in codec_configuration, clones and builds it using GitRepositoryClonerAndBuilder and returns the created object. Otherwise returns None.

Parameters:

  • codec_configuration (Dict) – Codec-specific configuration

  • global_configuration (Dict) – Global configuration

  • fulldocker (bool | None)

Returns:

GitRepositoryClonerAndBuilder instance or None

Return type:

Optional[GitRepositoryClonerAndBuilder]

create_codec_wrapper_instance(codec, codec_configuration, repository_obj=None)[source]

Imports the wrapper module/class and creates an instance configured with codec_configuration.

Parameters:

  • codec (str) – Codec name

  • codec_configuration (Dict) – Codec configuration

  • repository_obj (Optional[object]) – Optional repository object from clone_and_build_repo

Returns:

Configured codec wrapper instance

Return type:

object

process_codec_using_wrapper(codec_wrapper_instance, configuration, codec_configuration)[source]

Encodes and decodes all lightfields using the codec wrapper.

Parameters:

  • codec_wrapper_instance (object) – Prepared codec wrapper instance

  • configuration (ConfigurationReader) – Configuration reader

  • codec_configuration (Dict) – Codec-specific configuration

Returns:

None

Return type:

None

main(configuration=None, fulldocker=None)[source]

Encode and decode light fields using configured codecs.

Orchestrates the complete encoding/decoding pipeline: 1. Clones and builds codec repositories if configured 2. Initializes codec wrappers 3. Encodes all light fields at target bitrates 4. Decodes encoded files and converts to configured formats

Usage: python run_codecs.py <configuration.json>

Parameters:

  • configuration (ConfigurationReader) – Configuration reader (read from argv if None)

  • fulldocker (bool) – Whether to use full Docker for building and running codecs

Returns:

None

Return type:

None
