libva problem?
I am playing videos from my lubuntu computer to my tv through the hdmi
interface on my video card.

It has the mp4a codec also.
The one that used to work shows this in Tools/Messages:
vdpau_avcodec error: decoder profile not supported: 7
The new one that doesn't work shows this in Tools/Messages:
vdpau_avcod...

Should Join Discussion - Fwd: [whatwg] Give guidance about RFC 4281 codecs parameter
...sions etc. signalled, then a
parameter might be appropriate, and if the container formats are
general, a codecs parameter might be appropriate.
* H.264 Baseline profile video and Low-Complexity AAC audio in MP4
container. (video/mp4; .mp4)

H.264 was recently covered by 3GPP. See 26.244 V7.1.0 section A.2.2,
available from www.3gpp.org.
When the first element of a value is 'avc1', indicating H.264 (AVC)
video [29], the second element is the hexadecimal representation of
the following three bytes in the sequence para...

Video syntax
I'm planning to update Mango <http://mango.io/wtf?> to facilitate adding
video to Markdown documents. At the moment, of course, it's possible to
include video by including the appropriate HTML. There are three reasons,
though, that having syntax (official or unofficial) for video is a good
idea:
- *Simplicity.* Writing something like [youtube:gPbh6Ru7VVM] is easy.
