Google IMA ads not playing with DASH stream in iPhone simulation mode in Chrome browser #535

Open krackjack234 opened 3 years ago

krackjack234 commented 3 years ago

Description

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

Steps to Reproduce

Include step-by-step instructions on how 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=)
  4. Play the content

Expected Results

Preroll should play first followed by content

Actual Results

Preroll starts and gets stuck

Versions

videojs-contrib-ads version: 6.9.0

Video-js version: 2.11.0

videojs-ima: 1.11.0

Platforms

Browsers: eg. Chrome v94

OS/Devices: eg. Windows 10/Mac

Logs

Below error logs are printed when preroll gets stuck

dash.all.min.js:2 [1894][SourceBufferSink][video] SourceBufferSink error 
dash.all.min.js:2 [1894][SourceBufferSink][video] getAllBufferRanges exception: Failed to read the 'buffered' property from 'SourceBuffer': This SourceBuffer has been removed from the parent media source.

If we remove ads, dash content plays successfully in chrome browser in iPhone simulation mode

Note

Same issue is seen on Tizen TV. In order to debug this issue, we used iPhone simulator on Chrome as the behavior and logs are matching

The Chrome emulator is not a perfect fidelity simulation of an actual iOS environment, so some playback anomalies are not wholly unexpected there. However, DASH playback is not supported on iPhones, so the fact that it does not work there is consistent with actual iOS. The fact that you have seen a DASH stream play successfully in the Chrome iOS emulator without ads indicates a problem with the emulator, not the player or this plugin.
