This file lists the major changes between versions. For a more detailed list of every change, see the Git log.

Latest

  • Minor: Updated waf.

16.2.0

  • Minor: Added install step to CMake.

16.1.0

  • Minor: Upgrade to boost 4

16.0.1

  • Patch: Changed some size parameters and return values to uint64_t instead of uint32_t.
  • Patch: Added add_subdirectory guard in cmake.

16.0.0

  • Minor: Added cmake.
  • Major: Remove boost as external (i.e., non-internal dependency).
  • Major: Removed the extractor::file helper class. Use boost::memory_mapped_file directly instead.

15.0.1

  • Patch: Added missing virtual destructor in extractor interface.

15.0.0

  • Minor: Added templated version of box::get_children.
  • Minor: Added data_box::data().
  • Minor: Added extractor abstract class.
  • Major: Changed extractor open from open(error) to open(data, size, track_id, error).
  • Major: Changed extractor to now also need the track id of the track they should extract. Use the newly added track_extractor to get appropriate id.
  • Minor: Added looping API to extractor.
  • Minor: Added write_nalu_header and nalu_header_size to write_nalu_header.
  • Major: Removed annex_b_writer, nalu_extractor and avc_sample_access_layer avc_to_annex_b and addition to the avc_sample_extractor should be used instead.
  • Major: Replaced memory_mapped_file_layer with extractor::file and data_layer.
  • Major: Loop layer no disabled by default.

14.0.1

  • Patch: Fix bug where opening an extractor with a none existing file would cause an exception to be thrown.

14.0.0

  • Major: Upgrade to endian 10.

13.0.0

  • Major: Upgrade to endian 9.

12.0.0

  • Major: Correct spelling of descriptor/tag enums: elemetary_stream to elementary_stream, and ip_dentification_data_set to ip_identification_data_set.
  • Patch: Add virtual destructors to base classes.

11.0.0

  • Major: Upgrade to endian 8.

10.0.0

  • Major: Upgrade to endian 6.

9.1.0

  • Minor: Added samples function to extractors to get the number of samples.

9.0.0

  • Major: Changed API of sequence_parameter_set and picture_parameter_set. The constructor has been made private, and the object can now only be created using the static parse function.

8.0.1

  • Patch: Set the install_path of the petro shared lib to None to avoid automatic installation to system directories during the waf install step.

8.0.0

  • Major: Added error codes.
  • Major: bit_reader renamed to bit_stream.
  • Major: byte_stream was replaced by a wrapper of an endian::reader.
  • Major: The extractors open function now takes an error code and doesn't rely on the returned boolean to announce the occurrence of an error.
  • Major: sequence_parameter_set and picture_parameter_set now needs to be parsed.
  • Major: Changed constructor parameters of box.
  • Major: Renamed data_box::read to data_box::parse.
  • Major: Split box into two classes; box::box and box::data_box.

7.2.0

  • Minor: Moved avc_sample_access to it's own layer called avc_sample_access_layer.

7.1.0

  • Minor: Added missing functions to aac_sample_extractor.

7.0.0

  • Major: Upgrade to waf-tools 4
  • Major: Upgrade to boost 3
  • Minor: Upgrade to gtest 4
  • Minor: Upgrade to stub 6
  • Minor: Changed aac_sample_extractor to use the pimpl pattern.

6.0.0

  • Major: Removed the ambiguous timestamp function from extractors.
  • Minor: Added the media_duration function in timestamp_extractor_layer.
  • Minor: Use the total media duration as a loop offset for decoding and presentation timestamps in looper_layer.
  • Minor: Changed avc_sample_extractor to use the pimpl pattern.
  • Minor: Enabled building petro as a shared library

5.0.0

  • Major: Changed from using std::ifstream to using boost::iostreams::mapped_file_source for reading files.
  • Major: Changed the order of the parameters given to petro::parser::read now the parent paramter is the last one.
  • Major: Changed petro::parser::read to return a reference to the parent, and have a default value for the root paramter.
  • Major: The extractors now have an open function which are allowed to fail, instead of doing stuff that can fail in the constructor.
  • Major: Extractors are now split into seperate layers making it easier to test and reuse.
  • Major: bit_reader now takes size in bytes instead of bits.
  • Minor: Added data_offset function to byte_reader. Allowing a pointer to the current position of the byte_reader to be returned.
  • Major: picture_parameter_set and sequence_parameter_set now uses shallow storage.
  • Major: the read_time32 and read_time64 now returns a UTC time.
  • Patch: the read_time32 and read_time64 now handles timestamps before 1970-01-01 00:00:00.
  • Major: Renamed aac_extractor -> aac_sample_extractor.
  • Major: Renamed h264_extractor -> avc_sample_extractor.
  • Minor: Added annex_b_writer for writing annex_b samples.
  • Major: Added external dependency on boost.

4.0.0

  • Minor: Added the decoding_time helper function.
  • Minor: Added the aac_extractor and h264_extractor classes to extract AAC and H.264 samples and the corresponding timestamps from mp4 files. The extractors provide simple iteration over the available samples.
  • Major: The byte_stream constructor takes an istream reference instead of the filename as a string.

3.2.1

  • Patch: Made presentation_time inline to prevent multiple definitions linker error.

3.2.0
