Set the timeout in milliseconds to cancel a loading ad.
Groups adaptation sets and switches between them based on their group attribute instead of the recommended
SupplementalProperty urn:mpeg:dash:adaptation-set-switching:2016. Default is false.
Determines if the automatic quality switching is enabled on startup (true, default).
When converting mpeg2ts to mp4 segments we insert silence if we detect a drift between audio and video data to avoid getting out of sync. This tweak disables this functionality.
All HLS variants with a bitrate lower than the given bitrate in bits per second (bps) are considered audio-only variants and removed if there is at least one with a higher bitrate.
Enable or disable (false, default) hardware-supported video decoding for the Flash fallback. Enabling this might lead to decoding
artefacts, but can improve performance.
Sets the impression server to the given URL if it is included in PlayerAPI.getAvailableImpressionServers. Default is the first entry of the available impression servers.
Sets the license server to the given URL if it is included in PlayerAPI.getAvailableLicenseServers. Default is the first entry of the available license servers.
Sets the LOG_LEVEL of the player by calling PlayerAPI.setLogLevel.
Changes the maximum buffer level in seconds. Default is 40 seconds.
For live streams the lowest value of playlist duration for HLS, timeShiftBufferDepth for DASH and
the max_buffer_level is used as a maximum value for the buffer.
If enabled the native player used for HLS in Safari would fetch and parse the HLS playlist and trigger
an onError event if the download of a segment fails and the playback stalls. Default is false.
If enabled the native player used for HLS in Safari would fetch and parse the HLS playlist and trigger
{@link Events.ON_SEGMENT_PLAYBACK} events carrying segment-specific metadata like #EXT-X-PROGRAM-DATE-TIME
if present in the manifest. Default is false.
A list of audio codecs defining the preferred order. If a stream has multiple audio codec definitions in the
manifest for the same lang, the one which matches the lowest index in this list and is supported by the current
browser will be taken as default. The other ones will still be available for selection.
If none of the available codecs match anything in this list, the first one in the manifest which is supported
by the current browser will be taken.
Default value: ['ec-3', 'mp4a.a6', 'ac-3', 'mp4a.a5', 'mp4a.40']
A list of video codecs defining the preferred order. If there are multiple video adaptation sets defined in
the manifest (inside one Period), the codecs from the Representations will be compared against this list. The
lowest matching index which is supported by the current browser determines the chosen Adaptation Set.
If no codec in this list matches the available codecs, the first codec in the manifest which is supported by the
current browser will be taken.
Default value: ['av1', 'hevc', 'hvc', 'vp9', 'avc']
Query parameters are added as GET parameters to all request URLs (e.g. manifest, media segments, subtitle files, …). Query_parameters should be an object with key value pairs, where the keys are used as parameter name and the values as parameter values.
Example:
query_parameters : {
key1: 'value1',
key2: 'value2',
mycustomname: 'another-value'
}
The example above would be translated into MY_REQUEST_URL?key1=value1&key2=value2&mycustomname=another-value.
Amount of seconds the player buffers before playback starts again after a stall. Default is 0.9 seconds.
This value is restricted to the maximum value of the buffer minus 0.5 seconds.
If set to true, the mediaPresentationDuration (the total duration of the video) in the MPD is ignored
and the video is played until no more segments are available. This enables playback of MPDs with a wrong
mediaPresentationDuration. Default is false.
Amount of seconds the player buffers before playback starts. Default is 0.9 seconds.
This value is restricted to the maximum value of the buffer minus 0.5 seconds.
Enabling this flag prevents the player from downloading any further resource (playlist, segments, ...), when the
player is paused. Already issued requests will be finished. Default is false.

The tweaks configuration is used as an incubator for experimental features and also contains features implemented for specific customers that might not make it into the officially supported feature set.
Tweaks are not officially supported and are not guaranteed to be stable, i.e. their naming, functionality and API can change at any time within the tweaks or when being promoted to an official feature and moved into its final configuration namespace. Tweaks are often proof-of-concepts that are quickly implemented for urgent needs of customers. They often do not go through an architectural review and are therefore not signed and approved by the architecture team.
Example:
tweaks : { autoqualityswitching : true, max_buffer_level : 20, search_real_end : false, query_parameters : { key1: 'value1', key2: 'value2', mycustomname: 'another-value' } }
