(Core :: Audio/Video, defect)

Description

[Shian-Yow Wu [:swu]]

When playing YouTube video with Browser App by TV simulator[1], I encountered the following assertion error very easily.

MOZ_ASSERT(position >= mLastGoodPosition, "cubeb position shouldn't go backward");

STR:
1. Run TV simulator
2. Launch Browser App
3. Go to YouTube and watch a video
4. Click |mute| icon and refresh

This can be reproduced with Browser App on B2G desktop of phone build as well.

Revised STR:
1. Run TV simulator
2. Launch Browser App
3. Go to YouTube and watch a video
4. Click |mute| icon and make sure the video is playing
5. Click Refresh button
6. Repeat step 5 several times until assertion happens
