 |
|
VLC has had WebM support for a while (ffmpeg-0.5_p22846, vlc-1.1.0). This capability is now in GStreamer.
Two steps:
* Version bump from gst-plugins-good-0.10.22 to gst-plugins-good-0.10.23 (bug #329387)
* Version bump from gst-plugins-bad-0.10.18 to gst-plugins-bad-0.10.19 (bug #325171)
To find WebM content on YouTube, add "&webm=1" to the URL for search results (example). I can play such videos in Midori.
Parole-0.2.0.2 (the XFCE media player) doesn't want to play the WebM sample video on my hard disk. However, the following works from the command line:
| Code: | | gst-launch-0.10 -v filesrc location=sample.webm ! matroskademux name=demuxer demuxer. ! queue ! vp8dec ! xvimagesink fullscreen=1 demuxer. ! queue ! vorbisdec ! audioconvert ! audioresample ! alsasink |
Happy patent-unencumbered viewing!

Do you have gst-plugins-bad-0.10.19 installed? This provides the vp8dec element, in the file
| Code: | | /usr/lib/gstreamer-0.10/libgstvp8.so |

I thought I had. However I put files in /usr/local/portage/media-libs/media-libs/ instead of /usr/local/portage/media-libs.

I have the required versions of the libs installed but when I open a webm video with Movie Player, I get
| Quote: | | The playback of this movie requires a video/x-vp8 decoder plugin which is not installed. |
| Code: | emerge -pvD gst-plugins-good gst-plugins-bad
[...]
[ebuild R ] media-libs/gst-plugins-good-0.10.23 USE="-debug" 2,815 kB
[ebuild R ] media-libs/gst-plugins-bad-0.10.19 USE="-debug" 2,939 kB

I have ogg in my USE flags... Is there some other flag I am missing? |

D'oh!
Yup, that would be the way.
But I don't understand why I have to manually do that, I thought that the USE flags would cause that to get pulled in...
Thanks for your help, Hypnos! |

In principle, the USE flags applied to this or that media player (e.g., totem) should pull in the necessary gstreamer plugins, but not every possible USE flag is in the ebuild. For example, I have to install gst-plugins-soup manually to be able to listen to HTTP streams with totem or parole.
