Video Doesn't Play - Possible Encoding Issue

We're working with a client (located in Russia) that has a library of VoD clips aren't playing on their newly created Roku channel. When I attempt to play their videos, the VideoScreen's buffer screen is displayed for a second or two before the channel kicks back out to the SpringBoard screen. Below, I've included the encoding information of one of their clips (using ffprobe). I'm assuming it's an encoding issue; however, I've reviewed Roku's encoding guide at http://sdkdocs.roku.com/display/RokuSDK ... ding+Guide and nothing stood out as a red flag. Does anyone have any insight as to why this video clip won't play?

On my debug screen I see this:

------------
showHomeScreen | msg = MP4: unsupported object ID 0x5 in esds atom at 1046541 | index = 0
Video status: 0 0
showHomeScreen | msg = | index = -5
Video request failure: -5 1
showHomeScreen | msg = | index = 0

Re: Video Doesn't Play - Possible Encoding Issue

Yes there is an encoding problem with this stream. The esds atom in an MP4 file has a ObjectType byte that is supposed to identify the type of content. An MP4 H.264 video file normally has a value of 0x20. This stream has a value of 0x05 which according to this table means it contains an AFX stream.
