馃摉 Description of the problem
A regression got introduced in version
4.2.7where audio.codecs got rewrite (ref: #4858) with the corrected audio codecs.After this change, the player tries to play the audio stream with codec EC-3 instead of AC-3 (the original value provided by the manifest representation) due to the current implementation of supporting AC-3 on Tizen.
馃摎 Fix
Delegating the check from ac-3 to ec-3 in
stream_utilsto the actual media capabilities polyfill so that when a system is requesting the support ofAC-3audio codec on Tizen, we change the capabilities toEC-3and let it do its check.馃摀 Reference
This completes the work on 馃悰 #6160.
馃棐 Note
It was tested locally on a real Samsung TV (Tizen 5.0) in our internal project using Shaka as well as a dumbed down project with Shaka only providing the manifest listed in the bug.
