Transcoding - Recordings or Live

Thanks, that is simple and much easier than doing a restore from db backup! The oldest version I have is 2019.08.05.1456. I can confirm that hardware transcode works perfectly on this version.

To sum up:

Problem started for multiple (both low end and high end NAS) users sometime after 8/5 version!

@tmm1 is there anything else we can provide?

I have it working now using 2019.08.05.1456, so it was after that.

Wish there was a thread that just metioned each pre-release version number.

I understand it's too onerous to have to list all the changes in each pre-release, but sometimes you keep updating to each pre-release hoping it fixed an issue for you only to find out later that 20 versions back there was a bug introduced and ChannelsDVR doesn't save enough versions to let you get back the way I mentioned, so you have to reinstall and update to the latest released version.

If this can be done it would be great to be able to select which pre-release version you want to download instead of always getting the latest, (close eyes, hold breath and cross fingers) when shift-clicking on get update.

I don't think either of us knows what changed between 2019.08.03.0221 and 2019.08.05.1456.
I do know the last public release was 2019.08.03.0055

Thread should also have urls to download the versions, that way you can really pinpoint the issue, instead of relying on the few options previously downloaded through the update link.

Since there seem to be new beta versions every day now, sometimes a couple each day, I think it would be useful for anyone regularly updating/testing to have a longer version history.
I wrote the following bash script, which I have scheduled to run a couple times each week in Synology Task Scheduler.

#!/bin/bash
find /volume1/@appstore/ChannelsDVR/channels-dvr/ -name "20*" -type d -exec cp -avrf '{}' /volume1/channelsVersions/ ';'

It just copies the versions to a shared folder. "/volume1/channelsVersions/" is a share that I previously created in Synology File Station.

Sounds like a good idea, as long as you download every pre-release.
One could hope (due to the silence) the ChannelsDVR devs attended the Reno Hot August Nights event
https://hotaugustnights.net/

to hookup with the devs of VRD

Will this be addressed on Monday? Just checking for latest status :innocent:

The quality issue is fixed in the latest build.

Thank you, thank you.

Let me know if we need to check Experimental Transcoding, otherwise I will start testing again in 10 min.

AWESOME!

Latest 5 min test (only on TVE so far):

On iMac (i-5-7600):

Live - Transcoder intermittently drops to below 1.00, pause as buffer fills, resumes at +1.XX
Recorded - Excellent

On Qnap 251A:

Live - Transcoder intermittent drops...expected behavior as noted re: CPU in: Pixellation & Stuttering - TVE

Recorded - as expected as in above thread.

However, overall Live and Recorded is improved.

FYI: if you want to see log:
Attaching log for iMac only (Qnap testing will be continued for P & E -TVE thread)

A post was merged into an existing topic: Channels not using all tuners? (Bug)

No need for my reply back to @djcastaldo now

yes, glad the quality issue is fixed.
@DebbieFL The transcoder only runs for me on OTA channels, which are extremely high quality now. At 1080p 8mbps, which is what I usually have web-streaming set for on my gigabit network, TVE channels don't run transcode, only remux. If I drop down the bitrate of the web-streaming, transcoder will run, but I haven't experienced any intermittent pauses. This is on a Synology DS916+. Guess maybe I am suggesting that if you increase the bitrate, the issue will go away for TVE.

We are re-testing the transcoder change which caused some problems last week. It is available in v2019.08.13.0310

We have tested on DS916+ and DS918+ and are fairly confident it works as expected across CPUs now. More testing would be appreciated.

This bug has also been fixed in the latest build.

Is there a program you recommend for measuring CPU usage for transcoding in Windows 10?

I’ve been monitoring my NAS (Linux), I think in Win10 you have similar monitoring methods...but I’m a Win10 neophyte...hopefully other Win 10 users can assist here!
