Issues on midroll ads

gledezma · December 7, 2022, 4:57pm

Hi all

We are having some issues in AdError event with some midroll ads tests

We have two VAST files loaded at the start of the content, both of them can return a VAST, or sometimes, return an empty VAST. But sometimes, also returns internal ExoPlayer Codec Error
VAST1
VAST2

The problem is that we are having some intermitence in the AdError event so the Player is paused at mid content and not returning the player to play state.

Here are the logs:
Codec Error:

And here is the video, in which you can see at the start it plays without problem after the first AdError returned an empty VAST, but at the mid content, the player just pause the content and no AdError is returned.

Video - Google Drive

Here is our Ad Config and AdError Event

fun getAdConfig(dataMediaResponse: MediaPlaylist, custom6: String): AdvertisingConfig {

        urlPre = getVastUrl(dataMediaResponse, custom6, "pre")
        urlMid = getVastUrl(dataMediaResponse, custom6, "mid")

        Log.e("URL vast pre", urlPre)
        Log.e("URL vast mid", urlMid)

        val adSourcePre = AdSource(
            AdSourceType.Ima,
            urlPre)

        val adSourceMid = AdSource(
            AdSourceType.Ima,
            urlMid)

        val itemPre = AdItem(arrayOf(adSourcePre), position = "pre", replaceContentDuration = 0.0, preloadOffset = 8.0)
        val itemMid = AdItem(arrayOf(adSourceMid), position = "50%", replaceContentDuration = 0.0, preloadOffset = 8.0)

       return AdvertisingConfig(itemPre, itemMid)
}

----

private fun onAdErrorCallback(p0: PlayerEvent.AdError) {
        bView.loader.visibility = View.GONE
        bView.loaderLottie.cancelAnimation()
        contAdsErrors++
        Log.e("ad error msg", "${p0.message}")
        Log.e("ad error code", "${p0.code}")

        mPresenter.sendSentryError(p0)
        //If not empty, fallback logo
        if(contAdsErrors <= 2 && p0.code != 1009){
            /*Log.e("ad fallback", "yes")*/
            p0.message?.let {
                mPresenter.sendAnalyticsPlayerError(AnalyticsPlayer.PLAYER_ERROR,
                    it
                )
            }
            bView.bitmovinPlayerView.player?.scheduleAd(playerDataManager.getAdFallback())

        }
        bView.bitmovinPlayerView.player?.play()

}

Thanks in advance.

We are implementing Bitmovin Android v3.24.1

Hi @gledezma , thanks for sharing the behaviour. Looking at the first set of logs with codec error, the issues seems to be related to incompatible video codec format.

  com.google.android.exoplayer2.ExoPlaybackException: MediaCodecVideoRenderer error, index=0, format=Format(1, null, null, video/avc, avc1.4D002A, -1, null, [1980, 1080, 30.0], [-1, -1]), format_supported=NO_EXCEEDS_CAPABILITIES

Bitmovin Android player SDK offers videoFilter configuration which can be used to configure strict check for video codec support. The default value is Loose, which keeps in any video tracks which may be potentially supported. This can be configured as Strict to filter out any tracks which are not supported. You can try this configuration and see if it helps with codec error related behaviour.

We detected that our develop environment has too short contents, and the preload offset of the ads cannot be processed before because it needed more time that the actual content time.

i.e: Contents in our dev env are 12 seconds long, so first ad error appears without problem because is “pre” roll, but “mid” roll need at least 8 seconds to be preloaded in offset (that time was set for test) but half content is 6 seconds, so mid roll ad was never processed and fail to throw an ad error event. After noticing this we changed the preload offset to 5 seconds and then the second ad error event appeared. Check that if you can.

Thanks for sharing your findings @gledezma . These are indeed interesting. And as you found the likely cause of midroll Ads not getting processed.

I believe adjusting the preload offset as per the content durations in your environment has solved the problem.
