Multichannel view, an alternative approach

Playground
#25

I've pushed an update, bnhf/olivetin:latest (aka bnhf/olivetin:2025.07.03), primarily aimed at improving the initial Custom Channel setup for this project in CDVR-Sources -- when spun-up through Project One-Click.

For example, this set of values:

screenshot-htpc6-2025_07_03-10_37_12
screenshot-htpc6-2025_07_03-10_37_121014×706 73.1 KB

adds a Multichannel View stack to Portainer, and creates and initial Custom Channel Source M3U:

screenshot-htpc6-2025_07_03-09_21_49
screenshot-htpc6-2025_07_03-09_21_49801×520 44 KB

with EPG data that looks like this:

screenshot-htpc6-2025_07_03-09_23_101685×836 93.8 KB

Also, for @chDVRuser, this is the first test of having comments duplicated with the env vars in Portainer. If you're willing, give it a try, and let me know what you think back in the Project One-Click thread:

This is what I was able to capture when running Transcoder Probe from Advanced settings and choosing hardware transcoder and hardware deinterlacer on J4125

ffmpeg \

  -f lavfi -t 1 -i "testsrc=size=1280x720:rate=60,format=nv12,colorspace=all=bt2020:iall=bt2020:fast=0" \
  -vf format=nv12,hwupload \

  -color_primaries bt2020 -color_trc smpte2084 -colorspace bt2020nc \
  -f null -y /dev/null
#27

Would something like this work in ffmpeg? Or does it just not show up in Channels?

-metadata:s:a:0 title="Channel 6608"

#28

I tried -metadata:s:a:0 title="Audio CH 101" but even VLC wouldn't show it.

I believe audio labels are based on 3-letter language codes

#29

Just futzing around, I tried having the app rename the audio tracks to match the channel they came from, but it seems that required transcoding, so I backed out from trying further.

#30

Feeling quite inspired, and empowered by ChatGPT, I'm still futzing around. But this time, I feel a bit more successful! I liked the addition of the label overlays with channel numbers, but wanted them to display channel names instead. So I added an editable legend that allows for automatic translation. I also didn't want the labels to display persistently, so I added a customizable "fade in and fade out" duration. And since 36 works better for my eyes, I made the font SIZE configurable too. I also tinkered with some startup delays to decrease any errors or timeouts.

I'm completely new to this sort of thing but am learning quickly. I can't assure these additions will work for everybody nor am I a programmer to fix any of it, but I'm sharing in case anyone else might appreciate these ideas:

I'm playing with other label text effects and animations (slide in/out, slide down/up, grow/shrink, bounce, pulse etc.) and will share any notable successes as I achieve them. I'm also thinking that it might be nice to change up the placement, perhaps rotate or randomize from corner to corner? All in good time. I find all of this to be wildly exciting.

#33

Got this working great. Thank you for all of your help! Can I set up multiple of these on different channel numbers? If so, how do I do that? I'm trying to have at least college football, MLB and college basketball.

#34

You can. Edit Multichannel View under CDVR-Sources, and follow the structure shown there for the M3U.

Copy and paste the first entry to create a second, then change the tvg-id (add a 2, 3, etc after the MCH), modify the tvc-guide-title and tvc-guide-description to reflect the new mosaic of channels, change the name from College Sports to whatever, and modify the values in the URL with the new values you want for the 4 channels to combine.

Here's and example of what the first entry looks like on my system.

#EXTM3U

#EXTINF:-1 tvg-id="MCH" tvc-guide-placeholders="7200" tvc-guide-title="Mosaic of : 6142 ESPNUHD : 6144 SECH : 6147 ACC : 6199 BIG10HD " tvc-guide-description="Mosaic of : 6142 ESPNUHD : 6144 SECH : 6147 ACC : 6199 BIG10HD " tvc-guide-art="https://i.postimg.cc/pdCcpxMM/Multichannel-View.png" tvg-logo="https://i.postimg.cc/pdCcpxMM/Multichannel-View.png" group-title="HD",College Sports
http://htpc6:5001/combine?ch=6142&ch=6144&ch=6147&ch=6199

After you've added your new entry, save and then use the dropdown in the list of sources to reload the M3U.

#35

Works perfectly! Thank you.

I have installed Multichannel view through One-click. It is nearly working. The container is running on a Synology DS920+ which has a Intel Celeron J4125 quad-core processor which is capable of Intel Quicksync.
I have enabled the hardware acceleration lines in the stack/container, and am using h26_qsv for the codec.
I am getting some buffering where the pictures pause and the timeline pops up across the bottom of the screen, showing the spinning icon. It eventually catches up. But, buffers every few seconds.
The four channels are live webcams on YouTube, imported to Channels DVR using "Streaming Library Manager for Channels".

I would suggest installing intel-gpu-tools, and then running intel_gpu_top from the command line. Do this while using Multichannel View, and you'll be able to confirm if your GPU is being utilized.

#38

Is this something I install on the Synology NAS which hosts my DVR server?

#39

Since I know your Docker/Portainer installation is there too (which in this case is what would be utilizing the GPU), the answer is yes...

#40

Hmmm... This doesn't seem to be a simple thing to install on Synology at all. Is there a "for dummies" method? Or, perhaps, I should abandon the idea of using hardware acceleration.

I can say this... the Mosaic seems to be playing much better since I enabled hardware acceleration. Using libx264 software codec, it would scarcely load or play the channel. With h264_qsv codec, it will play for a few minutes at a time without problem. Then, it begins "buffering" and falls behind on the timeline. It will pause several times, over and over. Then, will play fine for a while. Though, never quite catching up on the timeline.

Right now, it has been playing for an hour or so, and is about 2-3 minutes behind...

#41

It sounds like it's working, but being able to confirm would be nice. Maybe @chDVRuser knows something about install regular Linux packages from the command line on Synology?

Something tells me these webcam streams might be a tricky test. Have you tried choosing 4x TVE streams? It'd be interesting to know how those appear to work. Also, you can try the h264_vaapi codec to see if that makes any difference.

#42

This won't play at all... Connection Lost. The h264_qsv codec seems to work the best.

I'm happy to try 4x TVE streams. I'll try to set up a new mosaic using your instructions from back a few posts earlier today.

#43

The 4x TVE streams play somewhat better than the 4x YouTube camera feeds do. Less pausing and buffering. But, not completely smooth. They start a bit better, and may play for longer without glitches.

On second glance, the TVE channels are having the same problems as well...

#44

The hardware is probably just too low-end. You could install this directly on a Windows PC or a Mac -- or it's running nicely for me on a Proxmox box (10th gen i7) in an LXC container (with Docker/Portainer running within). Lots of options. It requires a bit more oomph than basic single stream transcoding though.

#45

Nope.
It doesn't have the horsepower to do 4 hardware transcodes (My Synology DS1019+).
I found 3 was the limit (h264_vaapi), and I normally only do one at a time.
