[Feature Request] AC3 transcoding passthrough (for SPDIF) - MX Player

Hi,
can you add option to passthrough with DolbyDigital transcoding? (same as Kodi, used with AndroidTV especially for this function)
To play all 5.1 audio (aac, opus...) to SPDIF DolbyDigital (AC3 640k) with 5.1 channel.

HDMI pass through is already supported. We will forward your request to our product team for future developments on this. But, we can't provide any ETA at the moment.

This would be a great addition. There are so many AAC 5.1 video files right now and many Amps do not support AAC passthrough!

But you are supposed to go from box to TV over HDMI and from tv optical out to amp. Then it works.

Good ol' XBMC ? I'm interested to see how the x86 build (Kodi Beta 1) runs incl. support for bitstreaming HD audio over HDMI
and how far you can push H.264 1080p decoding (> 20 Mbps ??).
I'm still a bit sceptical about x86 Android with the push from Intel.

Also be sure to max out the quality settings in Plex. By default, and after every updated they change back to low setting that makes most stuff transcode rather than direct stream.
Also let us and Plex know if you get any pauses while playing content, or if it gets stuck on the last frame of direct streaming content like it does on the ADT-1... I been trying to get Plex dev's to acknowledge this for ages.

I'd love to know what codecs/containers both the integral atom can decode using MX player, etc as well as what XBMC/kodi can deal with on a mapped network drive with streamed native content (mkv, mp4, m4v, avi, x264, xvid, mpeg, ac3, aac, dts, mp3, etc). Thanks for offering to test!

Well for me and a few others who have ADT-1's and post on the Plex forums. We've been having an issue where on the last frame of a movie/tv show it will stop/pause on that frame, rather than gracefully return to the previous screen. But it only happens when content is direct streaming the video and transcoding the audio. Most likely all audio will be transcoded because if it has better than stereo sound, it will be transcoded to stereo, since that is all android built in media player (exoplayer) will output for non-google apps (they are supposedly working on adding AC3 passthrough).
As for the other comment about pauses, since the last plex release movies just seem to randomly pause requiring a fastforward/rewind/ or stop/play to get going again... not sure the conditions that this occurs for (transcoding, direct stream, ect).

Good lord, I didn't know that was an issue. It'd be an extremely poor livingroom media box if all networked streamed media was stereo only! The chromecast was recently updated with AC3 passthrough (finally) and has always supported AAC 5.1 via LPCM, but the chromecast still has no DTS passthrough just yet.
If Android has the same limitations as ChromeOS this will be a terrible media box indeed.

Yeah, it sucks. But at least I got a Google engineer to comment on G+. He said they are working on adding it. Alternatives are virtual surround sound on your receiver, or using a different media player (MX, XBMC, ect), since it's just software related.
I dunno why they don't just add options to passthrough all audio... do they need licenses to passthrough audio? If so they seems pretty stupid. How does XBMC get by with passthrough.... I'm sure they don't pay for licenses.

A license is indeed technically required to passthrough (which, as you state, is really stupid), however Roku somehow squeaked around that issue to support passthrough... they wouldn't detail how in their forums but did confirm that they did NOT get a license. Unfortunately the Roku isn't the best media box either as they don't internally transcode AAC 5.1 to LPCM, only downmix to stereo.
I would think a box as powerful as the Nexus Player would impliment internal transcoding of all 5.1 formats to LPCM 5.1 as the PS3 does, or give the option to passthrough. Heck, even my $79 blu-ray player from Sony transcodes AAC 5.1 to LPCM 5.1 and directly passes through AC3 and DTS. Google isn't a tiny op (like Roku)... this situation on Android, if it does exist on the Nexus Player, needs to be addressed ASAP.
I'm also very interested in which codecs are supported with plex. My Samsung tv does a tremendous job in playing more or less everything direct play. Chromecast on the other hand only do x264 (preferably in mp4 container). I have remuxed several of my dvds to mkv and kept the MPEG 2 video and ac3/DTS streams. Good for archiving. I wonder if Nexus player can handle at least MPEG 2. Ac3 seems to be under development for passthrough.
I also really hope they have not included cinavia protection!

The ADT-1 can decode 5.1, and output multichannel PCM, but only for select google apps; like Play Movies, ect.
When you think about it, HDMI cables should require a license to transfer AC3 and DTS from point A to B....lol I don't see how passthrough audio w/o decoding or touching it is any different.

Plex uses what ever media player is built in to said device. For Android, it's exoplayer. On your Samsung TV (and my own), it's Samsung's media player and their APIs that Plex use.
I know it uses internal player like exoplayer, but which codecs are supported with exoplayer on nexus player?

I couldn't agree more about the HDMI cable license as that would be common sense... the whole license deal is so screwed up for both audio and video and always has been. But Google could clearly afford to license properly for their media boxes!
As for Plex: its doubly important what the Nexus Player natively supports for those running Plex servers on non-Intel NAS devices such as most Synology NASes. Those don't have the power to transcode so Plex can only direct/bitstream for both video and audio. The Nexus Player needs to be robust in its native container and codec support to exist in a livingroom.
I wonder how kodi gets around the walled garden to bitstream properly over android's hdmi, or do they? I've never run XBMC/kodi on android.

They have it on Android. You need to enable expert settings then its listed. I just installed it the other day so I could watch something without it pausing all the time.
I'm sure as soon as the masses get their nexus players and complain to Plex they won't be able to ignore us on the bugs; like the pausing issue in their last android release.

Have you tested a bunch of containers and codes on the ADT-1's kodi? If it has native passthrough for both AC3 and DTS, does it also transcode AAC 5.1 to multichannel PCM or downmix to stereo PCM? I assume it natively supports all kinds of containers considering what the PC version can do, but it'd be great to try a variety to verify. How about xvid and/or mpeg-2? I'd also be interested how it supports .flac and other uncompressed audio codecs.

Just unload custom codec & try HW decoder. Soon MX Player will get audio pass through option. So that you pass the audio stream directly to the external device.

HDMI pass through is automatically used when the connected device can decode Audio HD codecs like ac3, TrueHD, DTS, etc.

Yes. HDMI Passthrough will be used when the codec is not supported by the MX Player & The same is supported by the device connected through HDMI.
We will improve it further in future to have more controls on the user side.

Hi dev. I tried with many 4k with AC3 or DTS streaming.. but i can't get audio work..
I use MX player 1.9.8 pro on my sony 9005 android tv, connected to the ampli by HDMI/ARC cable.
In codec menu, i check any kind of hardware supported codec.. and deselect SW render (only HW+ for video/audio).. but can't hear anything from my speaker..
With other app (for local file streamiing), amplifier automatically detect the audio format and give me on it display the correct format (DTS or DD).
With MX player pro and local/iptv streaming, i can't get it work.
Any idea?
Thank'you!!!

Hi
I must say that in 1.9.8 with HW+ there is no 5.1 sound passthrough to my Apmplituner No DD and no DTS.
In HW there is 5.1 passthrough to my Ampli but only DTS 5.1. Amplituner sees Dolby Digital but plays only in 2.0 - I don't know why but there is a problem with DD.
Best regards

Unfortunately, no. The only way is attempting to force pass through even if the hardware doesn't report the decoding capability. We will highlight this with our development and will get it prioritized for you.

Hdmi passthrough
Hi everybody,
I tried to play movies using default video player of the Android tv and it supports 5.1 Dolby digital passthrough via HDMI ARC. But passthrough using 3rd party video players like MX player, Kodi doesnt seems to decode the 5.1 audio where as PCM works just fine.
My TV: TCL 55 P8
AUDIO System: SONY HT IV300
Hi all,
I have also problem with audio passthrough over HDMI, I try to run Dolby Atmos on my Nvidia Shield, problem what I faced now is when I have video with Dolby Atmos it need HW+ to work but passthrough work only on HW decoder,
Also I cannot select subtitles from mkv video with HW decoder,
MX Player v1.25.8 (AndroidTV)
Device: Nvidia Shield
Audio: Yamaha RX-A2080
On going issue
This has been an on going issue with MX for years, I reported this over 3 years ago and still no solution. Stock reply is they're looking at it!
A simple forced pass through like VLC would do the job for most users with an amp but it's yet to come.
Even the pro version won't allow forced pass through.
Is this issue solved? What im looking for is play dolby digital movie in my android smart tv and get 5.1 sound from my sony e6100 home theater via HDMI ARC. It seems MX cant handle this.
Necro join. MX sends everything as dd2.0 regardless of any settings.
As mentioned above this has been a issue for years. When you mention it on other forums the common response is "Install the codecs" which doesnt work in this situation. A year or so ago I sent mxplayer support a email and got the arrogant response of "Mxplayer app is the ONLY app that properly detects if hdmi-passthrough should be enabled, otherwise very very bad things can happen." Well guess Im damn lucky my receiver hasnt burst into flames when pretty much any other player in existence uses it. Either the developer doesnt have the skill to correct this, or doesnt care. In my search I did find a similiar app that I hadnt heard of that works very well. Vimu Player.

AAC audio pass through is not supported at the moment.
But, ac3 should work. If you have custom codecs, kindly remove it & check again.

Pass through will be done only when there is no system or internal decoders.
Are you using any custom codecs? If you are using any custom codecs, audio won't be passed through as there is a FFmpeg side decoder. If you are not using any custom codecs, probably your system itself has support for ac3/dts.
Anyway, It will be improved in future.

Passtrought audio!

Hi everyone i have a problem with mx firestick 4k i can't adjust the audio pass. Amazon stick is inserted directly into the 2019 ts nr 696 model amplifier which supports all audio formats. Ms player on another android on egreat a 10 works great also goes hdmi cable through the amplifier and there application automatically when the sound is dolby digital or atmos or dts-x or truehd automatically switch to the amplifier sound.
But on firestick 4k I can't get this only dolby digital 2.0
Could this be fixed with an update would be greatly appreciated!
Many greetings from Zoran!:good:

Hi,
We would like to let you know that MX Player only enables audio passthrough mode only when the system reports the audio capability of the connected received. Based on the information you have provided, it seems that the FireTV stick doesn't report the HDMI audio capabilities properly. However, we will investigate this further and do our best to get a workaround if possible. Meanwhile, your patience is appreciated.
