expecting transcode to mp3 but playing native

Hi,

I have a DS413j, and it doesn't look powerful enough to transcode audio from AC3 to AAC, so zip told me to try mp3.

My videofiles are AVC HD video with AC3 audio, my DLNA renderer can play the video but it does not do AC3. I want the video to stay untouched, but transcode the audio to mp3. The profile that I'm using:

  Code:

<Transcoding>
                        <Video targetContainer="mpegts" targetACodec="mp3" >
                                <Matches container="*" aCodec="ac3" />
                                <Matches container="*" aCodec="wmav2" />
                                <Matches container="*" aCodec="wmapro" />
                                <Matches container="*" aCodec="flac" />
                                <Matches container="*" aCodec="vorbis" />
                                <Matches container="*" aCodec="truehd" />
                                <Matches container="*" aCodec="amrnb" />
                                <Matches container="*" aCodec="real" />
                                <Matches container="*" aCodec="dca" />
                        </Video>
                        <Audio targetContainer="mp3" aBitrate="320" >
                                <Matches container="flac" />
                                <Matches container="ogg" />
                                <Matches container="adts" />
                                <Matches container="mp2" />
                                <Matches container="wavpack" />
                                <Matches container="mpc" />
                                <Matches container="ape" />
                        </Audio>
                </Transcoding>


I'm assuming that it would transcode the audio, but when I put logging to DEBUG and try to play a file, this is what I see:

It says "delivering file in native format. Any ideas on what I'm doing wrong? Should I not see some audio transcode logging?

Thanks,

Btw, this was the trigger to try mp3, was hoping that this would use libshine, but have no idea how to check.

patters commented on Serviio 1.4 package for Synology NAS.

in response to marnik:

HI Patters, First of all: great work! I have a DS413j with the armv5 processor.I read that it’s too slow to do audio transcoding on the fly, do you know what the bottleneck is? I have sony camcorder files that have AVCHD and AC3 audio. My TV plays the video just fine over DLNA without [...]

Hi, change your profile to have it transcode audio to MP3. The libshine encoder I used since the last few versions should be able to handle realtime on ARMv5. libmp3lame which Serviio normally uses is very slow on CPUs without an FPU.

What is your device renderer, and what is the profile selected on serviio console ?

Device renderer is a STB. STB has no problem with the video, plays very smooth (great quality). STB also does AC3, as I have some live TV channels with AC3, but I don't have a surround set to play that out via optical. If I put "dolby digital" to "on" in my STB, I have no sound, qs the STB cannot downmix the surround.

I tried more or less the same setup with serviio on my laptop here, transcoding to AAC, which the STB plays fine. However, the NAS is not powrefull enough to do that, so I want to try in mp3, but it looks like it's not even trying to transcode.

This is the profile I'm using:

And as you can see in the logging, I have used Serviio Console to tell serviio to use that specific profile for my STB's IP (for some reason the device recognition is gailing). So it must be something with the profile.

Any ideas? Not sure if libshine is available in my ffmpeg build:

Although that is not the root of the problem, it's not even trying to transcode, which is what I don't understand.
