We are wondering about the consequences of animating the xlink:href attribute of a running media. Ex. : <video xlink:href="vid1.3gp" begin="0s" dur="media"> <set attributeName="xlink:href" to="vid2.3gp" begin="1s" dur="2s"/> </video> - at 0s, <video> renders "vid1.3gp" - at 1s, <video> renders "vid2.3gp". Is "vid2.3gp" started at 1s into the media, or at its beginning ? Should "vid1.3gp" be kept active in background ? - at 3s, <video> renders "vid1.3gp" again. Does it restart at the beginning or at 3s ? Should "vid2.3gp" be kept active in background ? What is the effect on the timing of <video> if the implicit durations of "vid1.3gp" and "vid2.3gp" are different ? Should the 'active end' be reevaluated at each change of the xlink:href attribute ? What is the consequence of the connexion and buffering phase which appears at the change between "vid1.3gp" and "vid2.3gp" ? We do not think the list of questions ends here. We believe this is a Pandora's box. One possible solution is to adopt text to the effect that changes to xlink:href are only taken into account when the media element is not active.
