386387 - ifilm videos do not play, only audio plays

Status: VERIFIED FIXED

(Core :: Layout, defect)

Description

Attachment: side by side comparison

When visiting ifilm, I noticed that only the audio track of video clips were playing.  No flash video control could even be seen.  This appears to be site specific as I can watch youtube, google, and metacafe videos with no problems.

It also appears to only affect 3.0-based builds, as I was testing it on Gran Paradiso 3.0a6 rc2 and confirmed it on the latest trunk nightly.  iFilm videos play fine in Firefox 2.0.0.4.

I have confirmed that this bug affects Windows XP, Vista, Linux, and Mac OSX.

Steps to reproduce:
1. Launch Gran Paradiso 3.0a6
2. Navigate to ifilm and click on a video clip

Actual Results:
Audio track of the video can be heard but no video can actually be seen.

Expected Results:
Video should play properly

Reproducible:
Always

On Linux, this regressed between 2007-03-25-04 and 2007-03-26-04: http://bonsai.mozilla.org/cvsquery.cgi?treeid=default&module=PhoenixTinderbox&branch=HEAD&branchtype=match&dir=&file=&filetype=notregexp&who=&whotype=match&sortby=Date&hours=2&date=explicit&mindate=2007-03-25+03&maxdate=2007-03-26+05&cvsroot=%2Fcvsroot

Eli, your patch for bug 375273 looks suspicious.

Checked in.  (Not easily automated for obvious reasons.)

Verified FIXED with Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a6pre) Gecko/20070702 Minefield/3.0a6pre using both the page on ifilm.com and the minimized testcase.

(In case anyone else didn't find the reasons Eli mentioned in comment 7 obvious, he meant because canvas's drawWindow() method can't draw plug-in content (bug 313462).)
