New to transcoding

I'm new to transcoding, so I may have missed something really simple.

I have some mp4 files

Trying to play back on a roku device. Typically i get no audio (which i think is to do the the AAC being 5.1, The other symptom is something the files plays at fast forward speed all the time someimes.

I have been trying to which part of the transcoding section is used, but cant see to see where this is selected
see below

I have tried to manually convert the files to aac stereo but still get no sound

To start with i'm just trying to find out where in the logs is the output which shows which transcoding section is selected. I cant seem to find it. Also changing the obvious section for 5.1 passthough makes no difference.

Any ideas how I found out which part of the profile be being selected and if possible the issue on my profile

Thanks

Re: New to transcoding

Got a little further, my original ffmpeg command to convert an mkv was
/usr/local/bin/ffmpeg -loglevel quiet -i "${filename}" -map 0:v -map 0:a -map 0:a -y -vcodec libx264 -c:a:0 libfdk_aac -b:a:0 384k -c:a:1 copy -disposition:a:1 0 -disposition:a:0 default "$DestFile" < /dev/null >/dev/null

and produced an mp4 with the following output

Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'output.mp4':
Metadata:
major_brand : isom
minor_version : 512
compatible_brands: isomiso2avc1mp41

Metadata:

Stream #0:2(eng): Audio: ac3 (ac-3 / 0x332D6361), 48000 Hz, 5.1(side), fltp, 384 kb/s




If I changed my conversion command to

/usr/local/bin/ffmpeg -loglevel quiet -i "${filename}" -map 0:v -map 0:a -map 0:a -y -vcodec libx264 -c:a:0 libfdk_aac -c:a:1 ac3 -b:a:0 384k -b:a:1 384k -ac:a:0 2 -ac:a:1 2 -disposition:a:1 0 -disposition:a:0 default "${file
name}" < /dev/null >/dev/null


I get the below which works

Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'output.mp4':

I tried playing with the Serviio profile especially the parts which specifically talk about Roku devices not supporting 5.1, but nothing works, always no sound, and sometimes the video speeds up for some reason.
Any ideas what i can change in the Roku profile to fix it, and remove the need to remove 5.1 sound from all videos ?

Re: New to transcoding

As you noted, the Roku will only play AAC audio in stereo. You would have the best success if you used ac3 as your audio, which the Roku supports in 5.1. You could of course also transcode using the normal Roku profile, which by default limits the bitrate and changes the audio to 2 channel.

What Roku player are you using? Do you have an AVR between the Roku and the TV to handle the audio? If so, how is it connected? HDMI or audio cables only?

Re: New to transcoding

I used to have just ac3 on some videos , and none of these videos played with audio, but the aac ones did. I found some documents on the net which i read as ac3 only works in pass though mode.
As i did not want to modify the original video or audio I thought the best way was just to add a track and change the default selection. Most videos started to work at that point, then i found a few with aac 5.1 which still did no work, and neither did transcoding using Serviio with the Roku profile selected.

My Roku is Roku 3 4200x with v 7.5 build 4096-04 and is connected via HDMI.

I have also tried to change the roku profile both following the comments in the profile and some of my own but whatever i changed did not work. I always copy the original profile back after any failed changes.

Any ideas would be much appreciated

Re: New to transcoding

I'm in the process of creating a bunch of Roku profiles. The existing profile is transcoding far more than necessary for the newer boxes, and doesn't account for 4K support for several Roku players. The profiles I am developing are designed to be used with an AVR, as I am not restricting the audio to AAC or stereo. I'll probably add a modified line so the user can switch to AAC stereo when only using TV audio. I'm just finalizing the Roku TV (non-4K) profile, although the only change a 4K Roku TV will need is to not transcode h265 video.

I'll be posting them here as I get them tested, but of course I don't have every model Roku so will need user feedback to tell if certain boxes need special configuration. Also, all Roku players identify themselves the same way, so the user will need to manually select the proper profile. But that only has to be done once, then Serviio will remember the setting, even after installed a new version of Serviio.
