Roku requires mp4v?

[mobamobamoba 5]

I noticed Emby was transcoding an mp4 to a Roku. I knew the bitrate of the file was under 1mbps and the Roku is set for 4mbps so on digging to figure out why Emby was transcoding, I saw the following in the log and was trying to figure out what it meant:

Info App: User policy for USERNAME. EnablePlaybackRemuxing: True EnableVideoPlaybackTranscoding: True EnableAudioPlaybackTranscoding: True 2018-09-17 00:13:01.498 Info App: Profile: Roku SG, Path: <PATH TO FILE>.mp4, isEligibleForDirectPlay: True, isEligibleForDirectStream: True 2018-09-17 00:13:01.514 Info App: Profile: VideoCodecProfile, DirectPlay=false. Reason=Roku SG.VideoCodecTag Condition: NotEquals. ConditionValue: mp4v. IsRequired: True. Path: <PATH TO FILE>.mp4

 

So Emby is transcoding because Roku requires an mp4v (whatever that is)? Thanks.

Hi.  What are the actual contents of that mp4?

 

If you can just post the transcode log from that session, we can see.

 

Thanks.

More Info:

(from wikipedia) The only official filename extension for MPEG-4 Part 14 files is .mp4.

 

Oh really. So, no wonder mp4v codec doesn't work in MKV. So the restriction for MP4V needs to check the container the media is in @ebr and if it is MKV only apply the restriction to transcode. If it is an MP4 container the mpeg4 part14 actually does play. So making note of this, not sure if you want to add into the code, since adding so much makes troubleshoot things later harder. This is just left on the table for the next meal. Will come back to this again and finish. Putting the little fly net covers over the food. We will be back to eat. 

 

So the limitation to limit the mp4v isnt required _IF_ the file is mp4 only if it is mkv. Since we are here lets finish it up.

snipped code - no give aways to p _ _ x.

I'm not entirely sure I do understand. The file itself - the container - is an MP4 not an MKV. So according to the above, it should direct play right?

The restriction ATM doesn't care what your extension is. Point blank, mp4v as a codec cannot direct play. This was known back then (a few days ago). This was left on the table. The official roku app doesn't track extension. This made this part require a later addition, as to not overwhelm ebr with information overload. Right now there is alot on his plate.

 

You can see above where the mp4v restriction is in the code, I pasted it. In this you can see the extension now will check if it is mkv before applying it. This will fix your issue.

 

@@ebr sorry to put so much in front of you at once. Better to get all this out of the way now. Less interruption for users, less remediation required for posts such as this. Win win all around. Go team emby!
