getSuitableEndCardCompanion

@Nullable
public static POBCompanion getSuitableEndCardCompanion(@NonNull
                                                                 java.util.List<POBCompanion> companions,
                                                                 int playerWidthInPx,
                                                                 int playerHeightInPx,
                                                                 float aspectRatioDeviationFactor,
                                                                 float playerWidthDeviationFactor)

To find out best matching companion from list of companion using below steps Step 1: Select companion ads which have renderingMode="end-card" Step 2: if there is not companion with renderingMode="end-card" then consider existing companion list Step 3: Calculate aspect ratio for size of each companion with current vast player size (in case of video interstitial it will screen size) Step 4: Pick companion having percent value nearest to 1 or with having correction not more than +/- 0.3 factor if any companion with above criteria is present in the provided list then return that companion else return null

Parameters:

companions - list of companion on which best matching algorithm is going to perform

playerWidthInPx - Pixel width of the player

playerHeightInPx - Pixel height of the player

aspectRatioDeviationFactor - Deviation factor for aspect ratio for companion ad w.r.t. player

playerWidthDeviationFactor - Deviation factor for companion width w.r.t. player width

Returns:

best matching the companion if present else return null

filterMediaFiles

@Nullable
public static POBMediaFile filterMediaFiles(@Nullable
                                                      java.util.List<POBMediaFile> mediaFileList,
                                                      @NonNull
                                                      POBVideoPlayerView.SupportedMediaType[] supportedMediaType,
                                                      int bitRate,
                                                      int width,
                                                      int height)

Filters and returns the POBMediaFile for matching inputs. returns nil if no match is found Note(Specific use case): If media file contains one of the supported media type other than webm then it does not add webm in the returning list, refer: https://inside.pubmatic.com:9443/jira/browse/SD-2283

Parameters:

mediaFileList - list of POBMediaFile objects

supportedMediaType - Support mime type

bitRate - expected bit rate value

width - width of media file

height - height of media file

Returns:

Returns the POBMediaFile for matching inputs

getScaleFactor

public static int getScaleFactor(android.content.Context context)

The scale factor of the display

Parameters:

context - application context

Returns:

if density greater than equals to 2.0f returns 2 else returns 1

getBitRate

public static int getBitRate(boolean isResolutionLow,
                             boolean isWifi)

Returns the bitrate for device screen scale/resolution and network. Possible values are: Low resolution devices with WiFi : 1000 For WiFi type carrier with high resolution : 2000 else for low resolution and non-WiFi carrier : 600

Parameters:

isResolutionLow - true for low resolution devices else false

isWifi - flag which indicates whether nework type is wifi or not

Returns:

Bit rate based on resolution and carrier type of device.

getSkipOffset

public static double getSkipOffset(double respSkipOffset,
                                   @NonNull
                                   POBVastPlayerConfig vastConfig,
                                   long mediaDuration)

To get best possible skip offset duration for vast player to show skip on it. 1. if Skip is 0 and no skipOffSet and mediaDuration is greater that maxDuration then show skip after maxDuration 2. if Skip is 0 and skipOffSet = X sec and x is less than mediaDuration then show skip after X sec else show skip after media duration 3. if Skip is 1, skipAfter= req.skipAfter and skipOffSet = X sec then show skip after skipAfter 4. if Skip is 1, skipAfter= req.x, skipMin= req.d and respSkipOffset is greater than skipMin then show skip skipAfter Assuming mediaDuration = 30sec & x, y > 0 Possible Cases -> expected values #non-skippable ads (skip = 0) respSkip = x, maxDuration = y -> Min(x,30) respSkip = 0, maxDuration = y -> Min(y,30) #skippable ads (skip = 1) skipAfter = 0, skipMin = 0 -> mediaDuration i.e. 30 skipAfter = 0, skipMin = 10 -> mediaDuration i.e. 30 skipAfter = x, skipMin = 0 -> Min(x,30) skipAfter = x, skipMin = 10 -> Min(x,30) skipAfter = x, skipMin = 35 -> mediaDuration i.e. 30

Parameters:

respSkipOffset - skip offset in the vast response

vastConfig - the vast configuration generated from vast response

mediaDuration - the media duration in seconds

Returns:

skip offset in seconds
