Samsung TV C/D/E Series -Buffers when transcoding

With the standard configuration, buffering occurs when transcoding.

change from:

<Matches container="mp4" vCodec="mpeg4" aCodec="lpcm" />
</Video>
<!-- transcode H264 MP4 files with LPCM audio -->
<Video targetContainer="mpegts" targetACodec="ac3">
<Matches container="mpegts" aCodec="mp2" />
<Matches container="mp4" aCodec="lpcm" />
<Matches container="flv" vCodec="h264" />
<Matches container="matroska" vCodec="h264" aCodec="flac" />
<Matches container="matroska" vCodec="h264" aCodec="vorbis" />
<Matches container="matroska" vCodec="h264" aCodec="truehd" />
<Matches container="matroska" vCodec="vc1" />
<Matches container="ogg" vCodec="mpeg4" />
<Matches container="3gp" aCodec="amrnb" />
</Video>

Changing the configuration to the following, buffering does not occur. However play time and file size information does not appear.

Change to:

<Matches container="mp4" vCodec="mpeg4" aCodec="aac" />
</Video>
<!-- transcode H264 MP4 files with AAC audio -->
<Video targetContainer="mpegts" targetACodec="ac3">
<Matches container="mpegts" aCodec="mp2" />
<Matches container="mp4" aCodec="aac" />
<Matches container="flv" vCodec="h264" />
<Matches container="matroska" vCodec="h264" aCodec="flac" />
<Matches container="matroska" vCodec="h264" aCodec="vorbis" />
<Matches container="matroska" vCodec="h264" aCodec="truehd" />
<Matches container="matroska" vCodec="vc1" />
<Matches container="ogg" vCodec="mpeg4" />
<Matches container="3gp" aCodec="amrnb" />
</Video>

What needs to be changed or added for the play time and file size information to appear.

That makes no sense. You are transcoding all mp4 files with aac audio, which should play natively and were most likely not transcoded. You lost file size because the file is now transcoded.

Okay, the original configuration with lpcm buffering occurs. When I change the configuration to aac buffering does not occur play time and file size indicates not available.

Can you post ffmpeg -i of the file?

you have to provide the full file path (incl. the file name), not just the folder path after the -i parameter.

Are you on wifi or wired connection?

My network wired and I am using the "C:\Program Files\Serviio\lib>ffmpeg.exe -i C:\Sanctum\Sanctum" command. Can you tell the correct command line to use?

I finally figured out the error. Below is the what you requested.

It looks like the TV has problems with the AAC audio in MP4 container, at least in your case. Try to upgrade firmware. Otherwise your fix will transcode audio to ac3, causing the missing information (filesize - we don't know the file size of the future transcoded file, duration - it's a problem with Samsungs, they ignore the data Serviio sends).

That is what I figured and Samsung has no recent firmware upgrades. Thanks for the help.
