The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

1.4.0 - 2023-02-25

Added

• Add support for byte-ranged HLS and DASH segments, i.e., HLS EXT-X-BYTERANGE and DASH SegmentBase. Byte-ranged segments will be downloaded using python-requests as aria2(c) does not support byte ranges.
• Added support for data URI scheme in ClearKey DRM, including support for the base64 extension.

Changed

• Increase the urllib3 connection pool max size from the default 10 to 16 * 2. This is to accommodate up to 16 byte-ranged segment downloads while still giving enough room for a few other connections.
• The urllib3 connection pool now blocks and waits if it's full. This removes the Connection Pool Limit warnings when downloading more than one byte-ranged segmented track at a time.
• Moved --log from the dl command to the entry command to allow logging of more than just the download command. With this change, the logs now include the initial root logs, including the version number.
• Disable the urllib3 InsecureRequestWarnings as these seem to occur when using HTTP+S proxies when connecting to an HTTPS URL. While not ideal, we can't solve this problem, and the warning logs are quite annoying.

Removed

• Remove the byte_range parameter from the aria2(c) downloader that was added in v1.3.0 as it turns out it doesn't actually work. Theoretically it should, but it seems aria2(c) doesn't honor the Range header correctly and fails.

Fixed

• Fix the JOC check on HLS playlists to check if audio channels are defined first.
• Fix decryption of AES-encrypted segments that are not pre-padded to AES-CBC boundary size (16 bytes).
• Fix the order of segment merging on Linux machines. On Windows, the pathlib.iterdir() function is always in order. However, on Linux, or at least some machines, this was not the case.
• Fix printing of the traceback when a download worker raises an unexpected exception.
• Fix initial creation of the config file if none was created yet.

1.3.1 - 2023-02-23

Fixed

• Fixed a regression where the track.path was only updated for Descriptor.URL downloads if it had DRM. This caused downloads of subtitles or DRM-free tracks using the URL descriptor to be broken (#33).
• Fixed a regression where title and track were not passed to the Service's functions for getting Widevine Service Certificates and Widevine Licenses.
• Corrected the Cookie Path that was logged when adding cookies with devine auth add.
• The Config data is now defaulted to an empty dictionary when completely empty or non-existent. This fixes a crash if you try to use devine auth add without a config file.

1.3.0 - 2023-02-22

Deprecated

• Support for Python 3.8 has been dropped. Support for Windows 7 ended in January 2020.
• Although Python 3.8 is the last version with support for Windows 7, the decision was made to drop support because the number of affected users would be low.
• You may be interested in https://github.com/adang1345/PythonWin7, which has newer installers with patched support.

Added

• Segmented HLS and DASH downloads now provide useful progress information using TQDM. Previously, aria2c would print progress information, but it was not very useful for segmented downloads due to how the information was presented.
• Segmented HLS and DASH downloads are now manually multi-threaded in a similar way to aria2c's --j=16.
• A class-function was added to the Widevine DRM class to obtain PSSH and KID information from init data by looking for PSSH and TENC boxes. This is an alternative to the from_track class-function when you only have the init data and not a track object.
• Aria2c now has the ability to silence progress output and provide extra arguments.

Changed

• The downloading system for HLS and DASH has been completely reworked. It no longer downloads segments, merges them, and then decrypts. Instead, it now downloads and decrypts each individual segment. It dynamically switches DRM and Init Data per-segment where needed, fully supporting multiple EXT-X-KEY, EXT-X-MAP, and EXT-X-DISCONTINUITY tags in HLS. You can now download DRM-encrypted and DRM-free segments from within the same manifest, as well as manifests with unique DRM per-segment. None of this was possible with the old method of downloading.
• If a HLS manifest or segment uses an EXT-X-KEY with the method of NONE, it is assumed that the manifest or segment is DRM-free. This behavior applies even if the manifest or segment has other EXT-X-KEY methods specified, as that would be a mistake in the manifest.
• HLS now uses the proxy when loading AES-128 DRM as ClearKey objects, which is required for some services. It will only be used if Track.needs_proxy is True.
• The Widevine and ClearKey DRM classes decrypt functions no longer ask for a track. Instead, they ask for an input file path to which it will decrypt. It will automatically delete the input file and put the decrypted data in its place.

Removed

• The AtomicSQL utility was removed because it did not actually assist in making the SQL connections thread-safe. It helped, but in an almost backwards and over-thought approach.

Fixed

• The Cacher expiration check now uses your local datetime timestamp over the UTC timestamp, which seems to have fixed early or late expiration if you are not at exactly UTC+00:00.
• The cookies file path is now checked to exist if supplied with the --cookies argument (#30).
• An error is now logged, and execution will end if none of the DRM for a HLS manifest or segment is supported.
• HLS now only loads AES-128 EXT-X-KEY methods as ClearKey DRM because it currently only supports AES-128.
• AtomicSQL was replaced with connection factory systems using thread-safe storage for SQL connections. All Vault SQL calls are now fully thread-safe.

1.2.0 - 2023-02-13

Deprecation Warning

• This release marks the end of support for Python 3.8.x.
• Although version 1.0.0 was intended to support Python 3.8.x, PyCharm failed to warn about a specific type annotation incompatibility. As a result, I was not aware that the support was not properly implemented.
• This release adds full support for Python 3.8.x, but it will be the only release with such support.

Added

• The dl command CLI now includes Bitrate Selection options: -vb/--vbitrate and -ab/--abitrate.
• The dl command CLI now includes an Audio Channels Selection option: -c/--channels.
• If a download worker fails abruptly, a full traceback will now be printed.
• The aria2c downloader has a new parameter for downloading a specific byte range.

Changed

• The usage of Path.with_stem with Path.with_suffix has been simplified to Path.with_name.
• When printing audio track information, the assumption that the audio is 2.0ch has been removed.
• If audio channels were previously set as an integer value, they are no longer transformed as e.g., 6ch and now follow the normal behavior of being defined as a float value, e.g., 6.0.
• Audio channels are now explicitly parsed as float values, therefore parsing of values such as 16/JOC (HLS) is no longer supported. The HLS manifest parser now assumes the track to be 5.1ch if the channels value is set to .../JOC.

Fixed

• Support for Python >=3.8.6,<3.9.0 has been fixed.
• The final fallback FPS value is now only obtained from the SegmentBase's timescale value if it exists.
• The FutureWarning that occurred when getting Segment URLs from SegmentTemplate DASH manifests has been removed.
• The HLS manifest parser now correctly sets the audio track's joc parameter.
• Some Segmented WEBVTT streams may have included the WEBVTT header data when converting to SubRip SRT. This issue has been fixed by separating the header from any previous caption before conversion.
• The DASH manifest parser now uses the final redirected URL as the manifest URI (#25).
• File move operations from or to different drives (e.g., importing a cookie from another drive in auth add) (#27).

1.1.0 - 2023-02-07

Added

• Added utility to change the video range flag between full(pc) and limited(tv).
• Added utility to test decoding of video and audio streams using FFmpeg.
• Added CHANGELOG.md

Changed

• The services and profiles listed by auth list are now sorted alphabetically.
• An explicit error is now logged when adding a Cookie to a Service under a duplicate name.

Fixed

• Corrected the organization name across the project from devine to devine-dl as devine was taken.
• Fixed startup crash if the config was not yet created or was blank.
• Fixed crash when using the cfg command to set a config option on new empty config files.
• Fixed crash when loading key vaults during the dl command.
• Fixed crash when using the auth list command when you do not have a Cookies data directory.
• Fixed crash when adding a Cookie using auth add to a Service that has no directory yet.
• Fixed crash when adding a Credential using auth add when it's the first ever credential, or first for the Service.
