#zoneminder

hm, its possible to use a socket or something else from an existing ffmpeg stream as input for a monitor?

so the usage of hwaccel is possible

ic0n: btw vaapi and ZM sucks

:)

you sucks

everybody sucks

yeah the vaapi support is not trivial. Some codecs you just tell it to use them, but not vaapi

I do intend to make it work someday.

the best is: use nvidia

thats incredible easy

like the mmal

No that's not good either. Their stuff is good for viewing a video, but getting the deoded image back out of gpu ram is hrad.

hopefully the ffmpeg libs will progress and make this easier. I will have to take a look at the state of things in newer ffmpeg

the best will be use ffmpeg directly instead of libvacodec

or?

no.

hey ffmpeg 4 is out...

cmon

using perl too

is that you moe?

but it works like a charm

hM?

i'm here, what's up ic0n

no that couldn't be me, i'm only node and php at heart

asker: In ZMN timeline, when viewing an event the prev and next event buttons only repeat the same event, also the red position marker/slider seems to do nothing.

asker: s/red/blue/

why is there any cpu usage at all for a monitor in just monitor mode without recording anything or doing any motion detection?

LiENUS: because the decode is done in the capture thread and doesn't know that it isn't being watched.

what does it need a decode for though?

isnt it just spitting out h264 frames for the browser to decode?

I don't believe browsers can play live H264 frames so it will need transcoding. Specifically, the video HTML5 tag doesn't support live streaming - it needs to be a fully constructed video file container like mp4. I believe in ZM they are rendered as mjpeg and are displayed by browsers. The common work around is to take live video feed, and start chunking them as mp4 files in 10 second segments - resulting in a delayed

"live" browser playback - but in either case, there is still server CPU usage. I know there is a dash plugin for browsers - not sure how that works

(thats just what I understand, and I often understand wrong)

i believe there are extensions to the video tag to support steaming nowadays, though perhaps zoneminder hasn't been modified to take advantage of that or perhaps there are other issues with the architecture that would conflict with

but i believe emby and plex pull off "live" playback of h264 without a plugin

that is what I am referring to "dash"

you don't need a plugin if the server is transcoding

my emby setup doesn't always transcode, sometimes its just streaming off disk

but then it also doesn't have the same things to cope with with a video file, it never has to save that file on its own

it never has to do motion analysis

streaming off disk means recorded video, not live

the transcoding is only needed for live

for a recorded movie/event, you just point the <video> tag of a browser to the mp4 and it plays natively

so for recorded content, the only time you need to re-transcode is when you need to change the quality, or format, like I sometimes need to do on plex

depending on what device I am playing it on

i believe it can repitch from other sources same as off a disk, it can stream from another emby server or from networked tuner without having to transcode (assuming those support a compatible format)

on plex live stream for example: https://support.plex.tv/articles/201161467-why-...

so bottom line - all live streaming solutions either need a browser plugin or a server transcode

I think most devices (at least ios and android) support m3u8 (HLS) playlists. I'd love to see an HLS transcoding server with ZM some day

then we can just do a <video src="url of m3u8"> and we get live. Of course, this also involves server transcoding - taking the camera feed and creating HLS segments

seems desktop chrome doesn't support it - needs a plugin called "native HLS player". still worth it imho

ic0n - should I be sticking to storageareas for updates now?

So apparently we don't have any documentation on Montage Review. I could have sworn we did. It didn't accidentally get deleted at any point in time did it? Anyone ever see any Montage Review documentation running streets looking for a home?

ic0n: with cuvid it seems its the same like mmal?

"easy"

youve got another opinion?
