No Audio on DirecTV HD DVR HR20

Hi,

I was able to get everything to work properly on my Sony BDP-S470.

But when trying it on my HR20, I am not getting any audio from my ripped DVDs. They are in 1 GB VOB files. The video looks great. I tried the AC3 to MP3 change in the config file and restarted the service. I also turned up the logging up to DEBUG, but that didn't show any issues in the log file. Here's what FFmpeg had to show for itself.

I'd say it is not the VOB file since it works on the Sony BDP. Any thoughts? Do you need any more info?

Thank you,

Okay, can anyone confirm that they are using VOB's with an HR20 and are getting sound?

I have an DTV HR23-700 and I have "no" audio on my copied DVDs also and I am running the .5 version of Serviio.

A number of people have found that change targetACodec to 'mp3' does not work, this was the case for me. However, 0.5 now supports target of 'mp2'. This works!
Gleaned this from: http://www.serviio.org/index.php?option ... icle&id=24

Sidenote: I also had to set downmix to stereo under video settings on the Transcoding Tab otherwise FFMPEG would croak claiming impossible bitrate (Before doing this, I would not even get video).

So can you post your final profile? I guess it could be included in the next release as the proper DirecTV profile...

I apologize for the slow reply, I haven't checked in in awhile. The full profile is...


<Profile id="6" name="DirecTV HD-DVR" extendsProfileId="1">
<Detection>
<HttpHeaders>
<User-Agent>.*DIRECTV.*</User-Agent>
</HttpHeaders>
</Detection>
<Transcoding>
<Video targetContainer="mpeg" targetVCodec="mpeg2video" targetACodec="mp2" maxVBitrate="8192">
<Matches container="matroska" />
<Matches container="mp4" />
<Matches container="asf" />
<Matches container="avi" />
</Video>
</Transcoding>
</Profile>

Also, in order to retain AC3 audio when streaming to my Samsung Bluray player, I unchecked downmix and applied the following as a hack...

moved my ffmpeg binary to ffmpeg.bin and created the following script in place of ffmpeg. Basically this looks for usage of mp2 codec (-acodec mp2) and if that is set, it replaces the 'ac N' argument with 'ac 2' since 2 channel audio is the only thing that's appropriate for mp2.

#!/usr/bin/perl
my $args = join(' ',@ARGV);
if ($args =~ /-acodec mp2/) {
$args =~ s/ac \d/ac 2/;
}
exec "$0.bin $args";

thanks, there is an option on transcoding config to forceStereo, so you won't need the script anymore

Awesome. Thank you!
