Video is corrupting when compiled with mxmlc but not Flash IDE

Question

I have movie clips containing FLV video sequences.

When this FLV plays in a SWF compiled from mxmlc, the video is completely corrupted - all different coloured blocks. If I compile from the IDE the video plays fine.

It's a bit more involved than this:

• If I play multiple copies of the same FLV at the same time, they're fine, whereas if I play various FLVs at the same time, they corrupt.
• They don't always corrupt on every playthrough - it's not consistent.
• If I zoom into the corrupted video, or move the player window, the corrupted image remains intact, i.e. it's not like a screen redrawing error where the corrupted area will often change or clear.

Does anyone know of any Flex compiler options, or SWC authoring strategies to get around this?

Why are you compiling flvs into the SWF? Wouldn't you want then to be external assets? – Peel

This is a game where the FLVs are used for interface effects - it's not video content per se, like a video player. – Gio

That makes a little more sense, then. My best advice is to be sure to file a bug at bugs.adobe.com and/or provide the code / assets to create a reproducible case. here. – Peel

@approxiblue - what worked was exporting a SWF containing the FLV assets from the Flash IDE, with the assets set with Actionscript linkage IDs. Then loading this SWF at runtime into the game SWF compiled with mxmlc - the FLV assets could then be instantiated with AS. This question is 5+ years old, and hopefully mxmlc, or the new compiler - whatever that's called - have been fixed now – Gio

I'm only editing because of the recent bounty. @how does tarling's update work for you? – Meltage

Which version of Flex are you using? Have you tried getting the latest Apache Flex SDK (which contains the latest mxmlc compiler) by installing it from flex.apache.org/installer.html – Brandie

I'm using the last version downloaded from official site. It seems like an old bug - flexcoders.10928.n7.nabble.com/… . When I compile the same code from Flash it shows everything perfectly so it might be something wrong with Flex. – Giglio

I'm using the last version of mxmlc - the problem is still there. It's most obviously a bug of Flex, but may be somebody knows a workaround without using IDE. – Giglio

I've tried these versions - all the same bad result: Apache Flex 4.14.1; Flex 4.6.0, AIR 18.0; Flex 3.6A, AIR 1.5.3 – Giglio
