arrbee99 1816 Posted July 28, 2019 Posted July 28, 2019 (edited) Was just watching on the dashboard Emby transcoding our rip of the Up DVD while its being watched remotely on Emby Theater. Am wondering if it should be transcoding and if so what I should do to get that, and other DVD rips, to direct play. Hopefully I haven't asked this before... Do you reckon its a Subs thing again ? Do I just need to tell them to turn Subs off ? Edited July 28, 2019 by arrbee99
Guest asrequested Posted July 28, 2019 Posted July 28, 2019 mpv should be able to play that. It's probably your upload bandwidth.
arrbee99 1816 Posted July 28, 2019 Author Posted July 28, 2019 Hokay. I guess I could run this kind of stuff through mkvtoolnix and get rid of pointless subs...
arrbee99 1816 Posted July 28, 2019 Author Posted July 28, 2019 mpv should be able to play that. It's probably your upload bandwidth. Unlikely, I've got 1000down/500up, they should have at least 100down. Is that megabits per sec or megabytes ? well, you get the idea.
Guest asrequested Posted July 28, 2019 Posted July 28, 2019 (edited) I'm curious about this..... Edited July 28, 2019 by Doofus
arrbee99 1816 Posted July 28, 2019 Author Posted July 28, 2019 Its an mkv file, so I presume that means yes. Think it plays OK, just hoping to get it to direct play, which my blurays do, though they've all been through Handbrake and had unnecessary stuff (audio/subs) removed. Like I say, I should try removing surplus stuff from this as well but thought I'd enquire for any hints here first.
Guest asrequested Posted July 28, 2019 Posted July 28, 2019 I'm ripping a DVD. I want to see what happens.....
Luke 42080 Posted July 28, 2019 Posted July 28, 2019 Did you explore the server dashboard or the video player stats to learn why it is transcoding?
arrbee99 1816 Posted July 28, 2019 Author Posted July 28, 2019 Did you explore the server dashboard or the video player stats to learn why it is transcoding? I just posted relevant stuff in the top post. Did forget to click on the 'i' on the server dashboard though and its too late now, they're watching The Incredibles, which is a bluray and direct plays. Now that I remember, I do have some versions of these DVDs which I've compressed (and cut down on languages and subs) which I can try here, assuming they behave the same played locally in Theater vs remotely in Theater. That'll have to be later though...
Guest asrequested Posted July 28, 2019 Posted July 28, 2019 Mine play directly. Post your transcode log.
arrbee99 1816 Posted July 28, 2019 Author Posted July 28, 2019 Mine play directly. Post your transcode log. Should be this... ffmpeg-transcode-c4c468e6-8433-462f-bad8-d2a7888fa064_1.txt
Guest asrequested Posted July 28, 2019 Posted July 28, 2019 (edited) Something wrong here. It's burning the subs in when it doesn't need to. Stream mapping: Stream #0:0 (mpeg2video) -> overlay:main Stream #0:5 (dvdsub) -> scale overlay -> Stream #0:0 (h264_qsv) Stream #0:1 -> #0:1 (copy) Unless there's something wrong with the Emby mpv build? I don't use it. I'll have to test one of my portables.... Edited July 28, 2019 by Doofus
Luke 42080 Posted July 28, 2019 Posted July 28, 2019 Nothing is wrong. His server dashboard and stats feature of the video player will indicate why it is transcoding.
Guest asrequested Posted July 28, 2019 Posted July 28, 2019 Well, I've tried multiple ways to make it do anything but play directly, and it won't The reason given is: TranscodeReasons=ContainerBitrateExceedsLimit Sooooo, internet bandwidth....
arrbee99 1816 Posted July 28, 2019 Author Posted July 28, 2019 I guess it could be. Media info for Up (DVD) gives about 8400kbps and The Incredibles (compressed BR) is about 8000kbps, so that bit extra could be significant. As I said we both should have pretty good internet and I just get the impression it transcodes for DVDs and direct plays for blurays when remote playing. But it'll probably take a while to spot a pattern as son No. 1 (the remote player) is pretty far away and only an occasional user. Will have to check it out the next time I spot him playing a DVD rip.

Then I changed it to 10 Mb/s, and it direct played. The Android app is using mpv. Edited July 28, 2019 by Doofus
vdatanet 1617 Posted July 28, 2019 Posted July 28, 2019 (edited) Auto usually fails to me. I don't know how the application calculates the available bandwidth. I have 600 Mbps Up / Down on the server side and 500/500 Mbps on the client side. Auto usually limit the bandwidth to 2.5 - 4 Mb/s and transcoding is firing. However, if I indicate the maximum bitrate manually, I have no problem and it direct plays. Edited July 28, 2019 by vdatanet
Guest asrequested Posted July 28, 2019 Posted July 28, 2019 It might be latency. Maybe when the server runs its test, it hits higher latency and chooses a safe bandwidth? It does seem extreme in your case, though.
vdatanet 1617 Posted July 28, 2019 Posted July 28, 2019 I have 10 ms of internet latency on both sides. On a remote connection the automatic bitrate detection is very very very conservative.
