Description

Google IMA ads are not playing with Dash stream on Chrome browser if we simulate for iPhone

Steps to reproduce

Explain in detail the exact steps necessary to reproduce the issue.

  1. Enable iPhone simulation in Chrome browser
  2. Use a dash stream as source (e.g. https://dash.akamaized.net/dash264/TestCases/1a/sony/SNE_DASH_SD_CASE1A_REVISED.mpd)
  3. Use a sample Google IMA tag (eg. http://pubads.g.doubleclick.net/gampad/ads?sz=640x480&iu=/124319096/external/ad_rule_samples&ciu_szs=300x250&ad_rule=1&impl=s&gdfp_req=1&env=vp&output=xml_vmap1&unviewed_position_start=1&cust_params=sample_ar%3Dpremidpostpod%26deployment%3Dgmf-js&cmsid=496&vid=short_onecue&correlator=)
    Play the content

Results

Expected

Preroll should play followed by ads

Actual

Preroll stops playing midway and dashjs throws buffer errors in console
