Transcoding using Intel 10700k

[Bobby121418 17]

Hi all,

Following on from the below thread I have now upgraded my Synology (xpenology) to SA6400 with a Intel 10700K.

I am trying to understand how transcoding works best with this new hardware given my broadband upload speed is limited to 17Mbps.

I have also had a look at the thread on Hardware Transcoding, but do not understand how this applies to Synology and more importantly, what to do.

I have set Hardware transcoding to Yes and it seems to work with CPU in low %s, however, the difficulty is with the buffering. So, if I set Quality to:

1. Auto, the result is 720p - 1Mbps, which is not the best. My question here is shouldn't Auto, set the best QoE and utilize as much of the bandwidth available?

2. 1080 20mbps - it buffers but when checked on Synology dashboard the uplink data rate is at 1.2MB/s, which is well below my upper limit of about 17mbps (2.1MB/s)

3. 1080 15mbps - it also buffers and data throughput rate is shown at 1.1MB/s

Can you please help guide on best settings or if something needs updating?

Attached are the recent test logs.

Thank you

Hi,

Following from above post, I have now installed 4.8.8.0-724080800, but still have at least question (1) from above:

When Quality is set to Auto, the result is 720p - 1Mbps, which is not the best. My question here is shouldn't Auto, set the best QoE and utilize as much of the bandwidth available?

Thanks

On the local network, yes that's what Auto does. Auto on the local network essentially means no limit. But on a remote connection, no, it is much more conservative.

Many users say that they should be able to handle a really high remote bandwidth, but then when they actually deep dive into it they find that they're being hit by ISP throttling on one side of the connection, or both.

It would be good if the option existed when on remote network, to set between a minimum (720, which is really low) and something else.

I wonder could transcripting not be done on a variable bit rate? Let say I want to let emby use as much bandwidth as available, but then let it reduce if other applications start using part of uplink bandwidth.

Thanks

Hi, it's possible for future updates. Thanks
