Help with simple transcoding (Samsung B Series)

Hi all,

Due to the problem (already discussed on another thread) about .mkv not being able to fast forward, i decided it would be simple enough just to transcode matroska to m2ts and that's that.

Original file .mkv:

Video: AVC
Audio: AC3

Samsung B Series: Plays Video and Audio perfect, but won't fast forward.

New transcoding profile setting:

<Video targetContainer="m2ts">
<Matches container="matroska" />
</Video>

End result:

Samsung B Series plays Video OK and has fast forward. But no audio...

So a opened up MediaInfo on the transcoded file and verified that it has Audio with AC3 (plays on the PC).

MediaInfo for the original file vs transcoded file:

Thanks for the help.

try to set targetACodec = "aac"

try to set targetACodec = "aac"

Hi zip,

I've set AAC and it works as 2 channels only (the TV probably only supports AC3 passthrough). In PC i get 5.1 AAC.
What happened with the AC3 transcoding? I know this was working in the past, as i used it frequently to do DTS to AC3.

Is this related to the ffmpeg version? Must i downgrade serviio to get this working again?

* UPDATE *

Note: I realized i posted the MediaInfo for a 2channel file, but i did all the testing with 5.1 channel files.

I decided to test one of my old DTS movie that i knew the dca transcoding profile worked on the past. With the 1.4.1 it also failed to recognize the AC3 Stream.
I tried to see if the problem was the ffmpeg by replacing with older versions, and no luck.

So i decided to install serviio 1.0.1 and play the DTS file and it worked on the TV.

I can see differences on the HTTP Headers (content-types, DLNA.ORG_PN and such) and on the ffmpeg arguments. Something got broken (for the Samsung B Series at least) from serviio 1.0 to 1.4. Any ideas?

thanks again.
