Unknown encoder when transcoding

[ctrlaltdefeat 8]

I get the following error when transcoding: Unknown encoder 'ac3'

 

How would I go around adding this encoder(and any others that may be missing, that I haven't found out about)?

Hi.  Are you using our Docker image?

 

If so, please look for an  update.

[ctrlaltdefeat 8]

That seems to have fixed the issue, thanks!

On the latest version I seem to still have issues with matroska @ 0x160a7c0] Subtitle codec 94213 is not supported.

Have you been able to transcode that file before? Can you try a different file? thanks.

[ctrlaltdefeat 8]

I can transcode the video myself just fine(outside of docker)

 

All my movies are released by the same group(and using the same kind of subtitles) and fail to be transcoded within docker

[Luke 40079]

Have you transcoded it before in Emby?

[ctrlaltdefeat 8]

No

 

I reinstalled Emby again last night, after not using it for.a long time.

 

This is pretty much the first video I'm trying to transcode since installing by again

[Luke 40079]

Can you provide a sample video for testing? Thanks.

[ctrlaltdefeat 8]

With my current upload speed it will take some time to make it available. I should have it ready in roughly 8 hours.

[Luke 40079]

Thanks. You can also slice a small portion of a file. If you do that, just make sure the smaller version exhibits the same problem. Thanks !

[ctrlaltdefeat 8]

Yeah, I considered slicing, but I don't have any software that can do it(nor am I familiar with it), and it would be totally me to accidentally make the file differently resulting in it not being of any use.

 

The video can be downloaded here here(4GB) : https://mega.nz/#!0cwG3ChY!ujHtc_8vPMYUpwYyPO7eueMD9h8F8FP56JulI-HUBNQ

[ctrlaltdefeat 8]

Any progress towards this?

 

Were you able to download the file? I'll take the link down if you got it

[Luke 40079]

Sorry, just started downloading, but please leave it up a little longer because i would like have to someone else download it as well for testing. thanks.

[ctrlaltdefeat 8]

Al right

tomorrow and the day after I'll be traveling, so I probably won't have time to touch anything for the next 3 days anyway

[Luke 40079]

Great, thanks.

[ctrlaltdefeat 8]

I'm at my destination, so I can test things now, if need be

[Luke 40079]

Thanks. We're still looking into it.

@ctraltdefeat I just pushed a new docker beta with an additional subtitle codec enabled, I believe this is the one you need. Could you please give it a try?

[ctrlaltdefeat 8]

I've updated to latest from the beta channel, but the issue persists: https://gist.github.com/CtrlAltDefeat94/da904b87b822cb8f414e11e8efa9db45
 

Rather than manually adding additional codecs when things fail, wouldn't it be more feasible to let Emby detect whether things are missing, and then add them if need be? 

[ctrlaltdefeat 8]

@alucryd, not sure if you get notifications from new replies topics you replied on, so tagging you to be sure

[Luke 40079]

We'll see what @@alucryd thinks. Thanks !

[ctrlaltdefeat 8]

(bump)

 

I'm traveling again and will be available for testing again on Monday

[Luke 40079]

We are still looking into it. You will get a response. Thanks.

[ctrlaltdefeat 8]

It's been some time. Has there been any progress on this, or is there any more information required?

The file is still available for downloading

 

 

additional info:

This command works:
ffmpeg -re -f matroska,webm -i file:"/mnt/media/Anime/Hataraku Saibou/[HorribleSubs] Hataraku Saibou - 10 [720p].mkv" -map 0:0 -map 0:1 -map 0:2 -codec:v:0 libx264 -force_key_frames "expr:gte(t,n_forced*5)" -vf "scale=trunc(min(max(iw\,ih*dar)\,720)/2)*2:trunc(ow/dar/2)*2" -pix_fmt yuv420p -preset superfast -crf 23 -maxrate 1308000 -bufsize 2616000 -x264opts:0 subme=0:me_range=4:rc_lookahead=10:me=dia:no_chroma_me:8x8dct=0:partitions=none -vsync -1 -map_metadata -1 -map_chapters -1 -threads 0 -codec:a:0 copy -codec:s:0 copy -disposition:s:0 default -y "/mnt/media/ProgramData/Emby/Sync/bee8ae9b059240dcb31b652d74303a04/81054295af87448e93ac93953912d081/42c490b6-eec3-4023-91f1-74084449ecfb.mkv"

 

Whereas this command does not

 

ffmpeg -re -f mov,mp4,m4a,3gp,3g2,mj2 -i file:"/mnt/media/Movies/Logan (2017)/Logan.2017.1080p.BluRay.x264.AC3-PxHD.mp4" -map 0:0 -map 0:1 -map 0:2 -codec:v:0 libx264 -force_key_frames "expr:gte(t,n_forced*5)" -vf "scale=trunc(min(max(iw\,ih*dar)\,720)/2)*2:trunc(ow/dar/2)*2" -pix_fmt yuv420p -preset superfast -crf 23 -maxrate 1116000 -bufsize 2232000 -x264opts:0 subme=0:me_range=4:rc_lookahead=10:me=dia:no_chroma_me:8x8dct=0:partitions=none -vsync -1 -map_metadata -1 -map_chapters -1 -threads 0 -codec:a:0 ac3 -ac 2 -ab 384000 -ar 44100 -af "volume=2" -codec:s:0 copy -disposition:s:0 default -y "/mnt/media/ProgramData/Emby/Sync/a863367ff3fd4d428fa355acf4d630a1/bd5dc7b9ddef4c838368feb2fa59bbf2/3435707a-5a0f-4cc5-807b-1f00e12bdbbf.mkv"

 

I'm not sure what parameter throws it off, or what any of them do for that matter
