Summary [Qt] video tag doesn't work in QtWebKit from Qt 4.7-git
Bernhard Rosenkraenzer
Reported 2010-08-19 07:08:25 PDT
With the version of QtWebKit included in the Qt 4.7 git repository, the video tag doesn't work. When going to what appears to e.g. http://chaos.troll.no/~tavestbo/webkit/mediaelement/ the poster is shown, but the video won't play. There's minor differences depending on which phonon backend is being used: phonon-gstreamer: The video simply doesn't play, no indication of what's going on and no indication of what's going on on the console. phonon-xine: The video doesn't play with no indication of what's going on Spewage on the console: params.c:OpenConfFile() - Unable to open configuration file "/home/arklinux/.smb/smb.conf": No such file or directory params.c:OpenConfFile() - Unable to open configuration file "/home/arklinux/.smb/smb.conf.append": No such file or directory Cannot connect to server socket err = Connection refused Cannot connect to server socket no message buffer overruns phonon-mplayer: browser crashes with an assert error inside phonon Spewage on console: setAspectRatio Aspect ratio: 0 objectDescriptionIndexes objectDescriptionProperties objectDescriptionIndexes objectDescriptionProperties subtitleAdded subtitleChanged New current subtitle: "None" startConnectionChange startConnectionChange Node: Phonon::MPlayer::MediaObject startConnectionChange Node: Phonon::MPlayer::VideoWidget connectNodes Phonon::MPlayer::MediaObject Phonon::MPlayer::VideoWidget endConnectionChange endConnectionChange Node: Phonon::MPlayer::MediaObject endConnectionChange Node: Phonon::MPlayer::VideoWidget startConnectionChange startConnectionChange Node: Phonon::MPlayer::MediaObject startConnectionChange Node: Phonon::MPlayer::AudioOutput connectNodes Phonon::MPlayer::MediaObject Phonon::MPlayer::AudioOutput endConnectionChange endConnectionChange Node: Phonon::MPlayer::MediaObject endConnectionChange Node: Phonon::MPlayer::AudioOutput setSource Source: "http://chaos.troll.no/~tavestbo/webkit/mediaelement/micmacs.sd.m4v" loadMedia "http://chaos.troll.no/~tavestbo/webkit/mediaelement/micmacs.sd.m4v" sendMPlayerCommand Error: MPlayer process not running resizeEvent Resize: QSize(0, 0) resizeEvent Resize: QSize(640, 426) MPlayerConfig Config file: "/home/arklinux/.config/phonon-mplayer/phonon-mplayer.conf" MPLAYER start Process started: "mplayer" "-identify -frames 0 -vo null -ao null http://chaos.troll.no/~tavestbo/webkit/mediaelement/micmacs.sd.m4v" MPLAYER MPlayer UNKNOWN-4.5.1 (C) 2000-2010 MPlayer Team MPlayer is from "2010" MPLAYER 159 audio & 341 video codecs MPLAYER Playing http://chaos.troll.no/~tavestbo/webkit/mediaelement/micmacs.sd.m4v.

On a side note: the styling given in the page ("background-color:magenta") is shown initially, but as soon as the poster image is loaded, the colors on the controls revert to their usual transparent gray.

We are working on new backends based on QtMultimedia. Hopefully this will solve the issues with the media elements on Linux. I close the task as we are not actively maintaining the Phonon backend anymore. If you want to make patches just comment and we'll reopen it.
