Internet & Networking Despite the recent interest in adopting HTML5's video tag, there is still one major problem: there is no mandated standard video codec for the video tag. The two main contestants are the proprietary and patended h264, and the open and free Theora. In a comment on an LWN.net article about this problematic situation, LWN reader Trelane posted an email exchange he had with MPEG-LA, which should further cement Theora as the obvious choice.

The size information would be in the HTTP header.

I miswrote. Not size. Length. HTTP doesn't tell you whether a clip is 3 or 5 minutes long.

The ogg wrapper is indeed designed as a streaming format, so that an in-progress stream can be picked up and played at any point, even in mid-transmission.

If there is indeed no size information in Theora packets as a consequence of this design, then why can't this length information (that being length of the video clip) simply be encoded as additional optional information as part of the HTML5 video tag?
