Can you please link the webpage with the video you were trying to view? Flash video players don't work when accessed directly via the SWF link.

That's an HTML5 video page and the video plays fine in modern browsers. Where did you even find a Flash element there?

Additionally, the video was published very recently.

the SWF link in the original issue post, can be found in the HTML source that I commented. so isn't that enough? I am not sure what you are looking for. the SWF URL is valid and can be downloaded

[Lord-McSweeney]

Most of the time, SWF video players get passed flash vars, which are parameters telling the file what video to play. Just opening the SWF will not give it the flashvars it needs, which the page containing the SWF would normally provide.

[n0samu]

It would definitely be interesting to see if their Flash video player is still working in the modern day, but I would need a page that actually uses the Flash video player to test it. As Lord-McSweeney said, the page source doesn't contain all of the necessary information (flashvars) that would make the video player actually functional.

[Lord-McSweeney]

It seems that even after passing flashvars and config XML files, it errors with the same error. This could indicate a problem with Ruffle's XML parsing.

looking at this page:

https://srv.veoh.com/videos/v39987670hewbtZa9

I see this in the source:

<embed
src='http://can.cbs.com/thunder/player/chrome/canplayer.swf' bgcolor='666666'
name='can' allowscriptaccess='never' allowfullscreen='true'
flashvars='pid=pUjYuZrmnWgT&partner=veoh&autoPlayVid=true&config=http://can.cbs.com/thunder/player/chrome/config/overrides/skin_ad.xml'
type='application/x-shockwave-flash'
pluginspage='http://www.macromedia.com/go/getflashplayer' height='469'
width='540' wmode="transparent"></embed>

so does that answer the question?

[Lord-McSweeney]

By removing the debug code, the SWF can be progressed to Modifying an XMLList object is not supported. Modified SWF with config: cbs-player.zip Run with -PautoPlayVid=true -Plink=/video/show-redirect/?pid=CB8k_SUiQLuVlvCrvR770DZwL8Zs13Ne -Ppid=CB8k_SUiQLuVlvCrvR770DZwL8Zs13Ne -Ppartner=cbs -Puvpc=http://web.archive.org/web/20110210072248/http://www.cbs.com/thunder/chromeless/pause_and_panel_ads.xml.

I can confirm @Lord-McSweeney result. Running the modified SWF with the given command returns the same error he is reporting. Is this a permanent limitation, or is it something that might be fixable?

[Lord-McSweeney]

The error is fixable- it's caused by Ruffle not yet implementing being able to modify XMLLists.

[Lord-McSweeney]

This now has the following error:

Error dispatching event EventObject(EventObject { type: "XMLConfigLoaderEvent.ON_CONFIG_READY", class: com.cbs.can.lib.config.xml.events::XMLConfigLoaderEvent, ptr: 0x562d229c08f0 }) to handler FunctionObject(FunctionObject { ptr: 0x562d22c79560 }) : TypeError: Error #1009: Cannot access a property or method of a null object reference.

This is because Ruffle doesn't support ?P< regex syntax.

(run with

ruffle canplayer.swf -PautoPlayVid=true -Plink=/video/show-redirect/?pid=CB8k_SUiQLuVlvCrvR770DZwL8Zs13Ne -Ppid=CB8k_SUiQLuVlvCrvR770DZwL8Zs13Ne -Ppartner=cbs -Puvpc=http://web.archive.org/web/20110210072248/http://www.cbs.com/thunder/chromeless/pause_and_panel_ads.xml --spoof-url http://can.cbs.com/thunder/player/chrome/canplayer.swf?allowScriptAccess=always\&allowFullScreen=true\&pid=u4uKImT6OqQR\&partner=pp_us_lcp_android\&autoPlayVid=false\&owner=CBS%20Production%20News
