  • Removed Compressed Mode audio delivery (WITH_COMPRESS_DATA_API build option). All integrations using compressed mode should migrate to Media Delivery (“playapi_media_tls” build profile). feature
  • Added OsConnectivityStatus() to arch example code. feature
  • Introduced a new API to allow starting playback with SpPlayOptions. This change simplifies “play uri” functionality by receiving the optional parameters in a single struct (rather than as individual params). api-change
  • Added support for shuffle_context parameter in SpPlayOptions. api-change
  • Added support for referrer in SpSourceInfo. api-change

Version 3.162.101

  • Changed the behaviour of SpPlayUri to stop the music immediately when called. Where it previously continued playback of current track till Backend response was received. fix
  • Fixed a bug where switching bitrate mid-track would not start the playback from the position where the bitrate change happened. This affected Media Delivery builds. fix
  • Disabled automatic bitrate switching. feature

Version 3.161.46

  • Fixed audio glitches with vorbis decoder example code. This was a regression in the example code shipped with eSDK versions >=3.157. fix
  • Fixed reporting of position in Media Delivery example code. The last_samples_buffered was not reset correctly during flush which caused the track position to have too big value after skip or seek. fix
  • Fixed a typo in SpLogSetLevel() documentation. fix
  • Added kSpErrorPlaybackInitiationTimeout to SpError enum. This is used to notify integration that SpPlayUri() timed out. api-change

  • Fixed a small typo in the documentation for is_group field in SpZeroConfDeviceAlias structure. fix

Version 3.159.86

  • Removed event kSpPlaybackNotifyTrackDelivered from the public API in Media Delivery builds. In the Media Delivery API, callback SpCallbackStreamEnd on_end is used instead to let the integration know that delivery of track data has finished. api-change

Version 3.158.86

  • Added an interface to check for audio decoder errors in the Media Delivery API example. fix
  • Set default log level to INFO in builds with verbose logging. Integration should use SpLogSetLevel() to set TRACE and DEBUG log levels. feature
  • Changed the example code audio_decoder.h seek() function definition to simplify the seeking logic in media_delivery.c feature

Version 3.157.78

  • Fixed minor errors in the device alias documentation (incorrect description of fields ‘isGroup’ and ‘alias_count’). fix
  • Updated examples for the proprietary metadata page. Relevant for Media Delivery API builds. fix
  • simplified ogg vorbis decoder in the example code. Relevant for Media Delivery API builds. feature
  • Added more precise seeking to ogg decoder example code. When seeking, samples from ogg pages before the actual location will be skipped and not played. Relevant for Media Delivery API builds. feature
  • Changed example code audio_decoder.h decode_and_output_to_audio_driver() to not return anything. Use finished() to check if the decoder has finished decoding. Relevant for Media Delivery API builds. feature
  • Removed written_frames() from audio_decoder.h API in the example code. Relevant for Media Delivery API builds. feature

Version 3.156.25

  • Fixed an issue where eSDK starts playback on skip and seek actions when the device is not in controllable state. With this fix the integration receives an error code kSpErrorDeviceUncontrollable. fix
  • Added SpContentType field to SpMetadata to indicate the type of the content (e.g. music track, podcast show episode, advertisement) in TPAPI configurations. fix
  • Added a new error code kSpErrorDeviceUncontrollable. eSDK returns this error code when integration calls playback APIs when the device is not controllable. fix

Version 3.155.22

  • Fixed track statistics reporting when seek was done while a track was playing but had been fully delivered using the Media Delivery API. fix

Version 3.152.41

  • Observed position is now reset when receiving observe commands without seek to value. Without this fix the incorrect position will be set after track change. fix

Version 3.151.52

  • Introduced a new API to operate on device’s controllable and active states. SpPlaybackSetAvailableToPlay() is marked as deprecated and the integration should use SpPlaybackSetDeviceControllable(), SpPlaybackIsDeviceControllable() and SpPlaybackSetDeviceInactive() instead. api-change
  • Fixed an issue where the current playback continues to play when eSDK fails to send a play command to the backend when an integration calls SpPlayUri() API. With this fix, eSDK pauses the current playback if eSDK fails to send a play command to the backend. fix

Version 3.150.82

  • Fixed use case diagram pictures for edge cases in Media Delivery API doxygen doc. fix
  • Fixed issue where media format restrictions wouldn’t survive re-login. fix
  • verified that the format of a fallback file is supported before playing it. fix

  • restored missing mbedTLS object files in the static library. fix
  • Fixed case where integration restricted capabilities immediately after SpInit(). The original capabilities set in SpInit() were ignored when restoring all capabilities. fix
  • Fixed an issue where restricted capabilities would be registered with Track Playback if restriction happened between initializing the eSDK and registering. fix
  • Fixed an issue where the currently playing file was unnecessarily reloaded and resumed. This happened when it was the preferred file (for the currently playing track) both before and after format capabilities changed. fix
  • renamed the field supported_media_formats_bitmask on struct SpFormat to media. api-change
  • renamed SP_MAX_SUPPORTED_DRM_FORMATS to SP_MAX_SUPPORTED_FORMATS. api-change

Version 3.148.40

  • Fixed an issue in Zeroconf urldecode where the ‘+’ character is not decoded as a space. fix
  • Added SpRestrictMediaFormat() and SpRestoreMediaFormat() API functions to update the list of supported DRM and media formats during runtime. feature

Version 3.147.79

  • Fixed c89 compatibility in mp3 decoder example code. fix
  • Changed the behaviour how eSDK becomes Active when SpPlayUri() is called. Previously eSDK would become Active immediately which could cause the old metadata being displayed for a short period of time. Now the Active status is not updated until the reply from the backend arrives and the metadata is updated. fix
  • Fixed an issue with multicast DNS server could fail after a network connectivity interruption. fix
  • Fixed an rarely occurring issue where the OGG decoder could fail during seek if a false sync sequence was hit in the input stream. A false sync sequence is some part of the compressed audio stream that happens to contain the start-of-page marker “OggS”. The symptoms would include an eSDK log message with the message “OUT OF RAM!”. fix
  • Fixed ogg decoder code example which would hang if seeking to or beyond the end of a track. fix
  • Fixed an issue where calls to SpPlayUri() might get lost between the pumps. fix

Migration to eSDK 3.147.79

  • Added API function SpLogGetLevels to get current logging levels from eSDK feature
  • Fixed an issue where socket communications fail in builds with custom socket HAL. The issue was caused by the “tls” field in struct SpSocketHandle not being initialized properly (introduced in eSDK release 3.117). fix
  • Fixed an issue where the process stack was mapped as executable (PROT_EXEC) on Linux platforms. fix
  • Fixed a bug where eSDK in bad network conditions would run out of network resources and become unresponsive until restart. fix

Version 3.121.19

Version 3.114.42

  • Introduced new device aliases. Backwards incompatible changes in API. feature
  • Fixed an issue where seeking back at the end of the track would play the next track instead fix

Migration of 3.114.42

  • In the new device alias implementation the selection of the alias is moved from the device login to the playback initiation. Because of this change parameters related to device alias selection are moved from login related functions to the functions responsible for starting playback of a context.

  • Functions that lost alias index (alias id or index should be removed from the call):
    • SpCallbackConnectionNewCredentials
    • SpConnectionLoginBlob
    • SpConnectionLoginUnscrambledBlob
    • SpZeroConfGetVars
    • SpConnectionLoginZeroConf
  • Functions that got alias index:
    • SpPlaybackPlay
    • SpPlayUriAtByteOffset
    • SpPlayUri
    • SpPlaybackBecomeActiveDevice
    • SpPlayPreset
    • SpPlayPresetEx
  • From now on the integration has to either use old style display name or device aliases. These two approaches can not be combined. If the integration does not use aliases then use:
    • display_name in in SpConfig structure
    • SpSetDisplayName()
    • SpSetDeviceIsGroup()
    • SP_NO_ALIAS_SELECTED as an alias index

With the device aliases use: * device_aliases in SpConfig structure * SpGetSelectedDeviceAlias() * SpSetDeviceAliases()
