TYPO3 Core

I have the same fatal error when using HTML5 Video and add any parameter. In my case, the width and height fields are empty.

The same here when i delete the empty "audio description for videos" field in "HTML5 Additions".
Using width and height settings is not the problem here.

TYPO3 6.2.2

I located the following behavior:

• make new content element media and don't touch the "audio description for videos" or "Additional Parameters". Everything is fine.
• edit this content element add a new empty "audio description for videos" or "Additional Parameters" and save. Problem with video in chrome but FF and opera all is working fine.
• edit this content element again and delete the empty "audio description for videos" or "Additional Parameters". Fatal Error like above is showing in frontend.

When content element has one time a "audio description for videos" or "Additional Parameters" added the at least one empty param is needed.
Width and height is every time set.

I realized when i first choose "HTML5/accessible rendering" and set a video in the HTML5 tab and after that when i delete the video in the HTML5 tab and disable "HTML5/accessible rendering" there is still an empty flexform in the database.

with HTML5:
<sheet index="sVideoAccessible">
<language index="lDEF">
<field index="mmCaption">
<value index="vDEF"></value>
</field>
<field index="mmSources">
<el index="el">
<section index="1">
<itemType index="mmSourcesContainer">
<el>
<field index="mmSource">
<value index="vDEF">file:45</value>
</field>
</el>
</itemType>
<itemType index="_TOGGLE">0</itemType>
</section>
</el>
</field>
</language>
</sheet>

after HTML5 deaktivating:
<sheet index="sVideoAccessible">
<language index="lDEF">
<field index="mmCaption">
<value index="vDEF"></value>
</field>
<field index="mmSources">
<el index="el">
</el>
</field>
</language>
</sheet>

Maybee thats the problem.

If i remove the empty and unused flexform entries for the HTML5 configuration "<sheet index="sVideoAccessible">" the error disapear.

I'm still not able to reproduce the problem.

Can somebody please post a complete stack trace?
(enable the Development Preset in the Install Tool, to get the full stack trace)

It's quite easy to reproduce it, just add some dynamic properties / save / edit / remove them .. After that rendering of media is broken.
Here is a stack trace : http://pastebin.com/raw.php?i=gMNBevtM
