archangelz 13 Posted May 7, 2015 Share Posted May 7, 2015 A couple of problems have popped up with the settings->playback->streaming setting. Say for example I set the "client bitrate limit" to 100Mbps, on the remote web client what I am finding is even if I have my playback setting at "720p 1Mpbs", the server will try to transcode this as a 100Mbps webm regardless of setting requested on web client. I had it set to 10Mbps because of my connection upload is that speed but then every external web client I had started trying to transcode at that. Tried this on several LiveTV streams. Also the client does not differentiate between a local network and a remote client? Which is what I thought this setting was for. If you have a 10Mbps upload speed cap on your internet connection, this does not necessarily apply to your LAN. Setting this limit applies to both your LAN and your external clients, which cuts the quality on your LAN clients. Can post logs if needed, but this is easily reproducible.

Luke 37110 Posted May 7, 2015 Share Posted May 7, 2015 the server doesn't transcode at 100mbps. the params it passes into ffmpeg are a max rate, not a desired rate. we do plan to add local/remote bitrate settings Link to comment Share on other sites More sharing options...
archangelz 13 Posted May 7, 2015 Author Share Posted May 7, 2015 (edited) the server doesn't transcode at 100mbps. the params it passes into ffmpeg are a max rate, not a desired rate. we do plan to add local/remote bitrate settings When I looked under the settings menu active devices it's says the bitrate being set to 100? This used to say 1Mbps based on what the client requested setting is. The speed at which my server can transcode is also messed up. My CPU gets pinned when that setting set when it previously wouldn't and client stream playback is unusually slow. I haven't looked at logs though but I can post if required. I know the content is at 4Mbps so even if it transcoded to that it shouldn't be that slow or it should show what the max is for the asset no?

archangelz 13 Posted May 7, 2015 Author Share Posted May 7, 2015 (edited) So it looks like the server is ignoring the client requested 1Mbps bitrate and using the maximum of the source material? Looking at the webm file in the transcode cache, the transcoded file is not 1Mbps but the source 15/16Mbps? If the client downstream bandwidth was limited or the server upstream bandwidth was, this would be a problem if the max rate being passed in instead of the client desired rate no? The setting isn't really a maximum stream playback limit for the client so much as a peak transcode limit then Also confirmed the it is likely a reporting problem for the 100Mbps thing.

Luke 37110 Posted May 8, 2015 Share Posted May 8, 2015 only way that could happen is if the server doesn't know the birate of the source material. we have to pass in a bitrate value to the encoder or it gets left to encoder defaults and looks bad. so we do a comparison between source and client setting. at the time you played it the media info displayed in the web client probably was missing it's bitrate or other info. i would try refreshing that item.

This particular item can't be refreshed though. It's not something in my library as it is hosted externally through the Hockeystreams plugin. Refresh wouldn't help in this case.

Luke 37110 Posted May 8, 2015 Share Posted May 8, 2015 Then there's nothing that can be done if the plugin doesn't provide any media information. Why not just lower the bitrate. Who really needs 100 Link to comment Share on other sites More sharing options...

Who really needs 100 Oh I don't need the 100, it just just an example higher than any asset I had to try to find what pinned the upstream connection and CPU the other night. What would happen though is if I have the limit set to my maximum upstream and one client starts streaming hockeystreams, it would chew up the maximum of my upstream bandwidth and starve all the other clients not using hockeystreams. Could the server not just use the client requested setting then if the media information is not provided or missing? All of hockeystreams streams are at 3Mbps, maybe I will request the curator for that one to add that into the media information. So what can I set the limit to right now as a workaround so the streaming plugin doesn't chew up all the upstream bandwidth? My understanding is the upstream bandwidth limit is a shared pipe across all clients connected to the server. Even if the limit is lowered, the other clients would still starve no?

Luke 37110 Posted May 8, 2015 Share Posted May 8, 2015 Could the server not just use the client requested setting then if the media information is not provided or missing? ?? That is exactly what we are doing here. There is nothing that says hey let's use 100 because we don't have any info. It is coming from the client request. You are better off letting the client worry about their own needs and have them specify 3Mbps. Then in the server dashboard take a look at Playback -> Streaming.

It is coming from the client request. You are better off letting the client worry about their own needs and have them specify 3Mbps. Then in the server dashboard take a look at Playback -> Streaming. Thanks for reply Luke, What I mean is the dashboard playback->Streaming setting. Is that the limit per client or is that the total limit shared by all clients? "An optional streaming bitrate limit for all remote clients. This is useful to prevent clients from requesting a higher bitrate than your connection can handle." I'm not clear on what "all" means. if I set the playback->streaming limit to 5Mbps, does that mean the 5Mbps is what is allowed by each remote client? or is it if three users are connected they each get 1.67Mbps maximum? If the former, then I'll be okay since I'll be able to set the limit to 1Mbps on each client or something that works for my upstream cap. If the latter, any time hockeystreams is in use it will transcode to 5Mbps because no media info was provided by the plugin (post #8 issue) and server leaves no bandwidth for the other two connected clients because of the applied playback->streaming setting. Which case is it? And if there it's the second case is there a workaround? The client in all my testing was requesting 720p 1Mbps but the server and transcoding logs showed it was higher (100Mbps in my extreme case). Am I misunderstanding the transcoding problem from my earlier post or the playback->streaming setting limit usage?

saitoh183 137 Posted May 8, 2015 Share Posted May 8, 2015 @@Luke Im having similar problems. Most of my external users use the webclient. Does the webclient always transcode content regarless of container/codecs? I have throttle enabled and set max bitrate to 1.5Mbps but often i will have 2 people connected via webclient (Chrome) both transcoding and the ffmpeg is just killing the CPU (99%) and people will get stutter because show progress bar catches transcode progress bar. Is there any way to achieve direct stream via the webclient? @@Angelblue05 played the same file and got direct stream (mp4 AAC H264) Link to comment Share on other sites More sharing options...
Angelblue05 4130 Posted May 8, 2015 Share Posted May 8, 2015 (edited) In kodi, that is. In the webclient it just transcodes no matter the bitrate setting - I would at least except the webclient to direct stream mp4 aac h264 content, but it doesn't seem to be the case :/ Sent from my iPhone using Tapatalk Edited May 8, 2015 by Angelblue05 Link to comment Share on other sites More sharing options...

Angelblue05 4130 Posted May 9, 2015 Share Posted May 9, 2015 (edited) Yes, the webclient force transcode everything on my local network. Did something change in the way the detection works? Let's take, for example - Catfish the TV show Media info - MP4 container - H264 video - AAC audio - Is supported by Chrome according to this https://developer.mozilla.org/en-US/docs/Web/HTML/Supported_media_formats: When I play in the webclient on Chrome, this is all I can select: In my Emby server - I have not set a limit for bitrate and the transcoding is set to auto. Yet I'm not presented with Direct play or Direct stream. @@Luke So the question is, how can Direct play and Direct stream be achieved in the webclient. When I think of all my users being force to transcode using the simplest interface that is the Webclient, my spine shivers....and no wonder people's cpu can't keep up when everything is forced to transcode on the webclient, when it's not even necessary in the first place (for mp4-h264-aac, that is). Oh, and I forgot to point out the fact that quality is very degraded in the webclient (probably due to transcoding).... And this was on local network.
