Add maxVBitrate to Online transcoding directives for Samsung C/D and Samsung E/F profiles

[Otto Dandenell]

There is a problem with "Video format not supported" with some Online streams when watching through a Samsung BD player.

The solution is documented here: http://forum.serviio.org/viewtopic.php?f=7&t=15544&p=95586#p95586

There are no errors logged, but the playback is stopped with a message about incompatible video type. Until I add the maxVBitrate="16384" attribute to the OnlineTranscoding --> Video nodes.

A followup to the referenced forum post says: "Samsung D-series needs maxVBitrate on mpeg2video transcoding and you can set the value to 30000."

So, this (30000) would probably be a more suitable value

See ticket 435. This is caused by out of date firmware on the TV. Fix is to update the firmware.

[Otto Dandenell]

OK, jhb50, thanks for the suggestion.

[Otto Dandenell]

I have nor read through ticket #435.

Peter, please don't close this ticket until I have verified that there is indeed a firmware update to my Blueray player available and that it fixes the issue.

The online transcoding has worked great for the tv service which I usually use (svtplay.se), but now I am developing a plugin for another service (tv3play.se) which seems to be encoding their streams in a slightly different format. So I am thinking that it may be the same old bug, only with a higher bitrate limit than before.

I'll look into it this evening and report back.

No further info received, so closing.
