Error transcoding media - Failed to download XML for codec 'h264_decoder'

Plex Media Server
1

Server Version#: Version 1.24.0.4897
Player Version#: AppleTV (latest)

I’m playing Media after setting the Convert Automatically setting. The screen shows an error that says “Something went wrong with your media, please try again. Conversion Failed. A required Codec could not be found or failed to install.”

Here’s a log snippit:

This started to occur after I installed 1.24.0.4897. Any help would be appreciated.

Thanks Jamie

Please include the logs ZIP which contains a captured failure.

As you see above, it’s not possible to diagnose a snippet.

Ooops sorry.

Here’s the zip.

Hate to do this to you.

Please turn DEBUG logging back on? (click SAVE)

Now recreate it one more time.

You don’t save any space but with DEBUG on , I can see what it was trying to do.

At this point, all I have are vague error messages.

see? this is what they look like

Verbose logging enabled.

I think I see what the problem might be. Looks like a networking issue. Standby…

7

@ChuckPa - OK, downloads.plex.tv (and only that domain) was not resolving correctly. Fix the network issue and all is well. Thanks for your help.

Plex is awesome

8

Didn’t ask for VERBOSE… That is over kill and only captures 2 minutes plus makes it VERY diffcult to diagnose.

DEBUG only please :slight_smile:

Future reference. (that is the default for a reason :wink: )

9

I’ll remember for next time. I thought debug was enabled the first time, Oh, well.
