Frigate won't play .mp4 on review page, loading forever

[screwb0x]

Hi,
so i set up Frigate with just 2 cams and I'm quite happy with it. But, those cameras don't have a rtsp stream. I can grab the stream via http and all is working. Basicly all the log is saying:
"Copied /media/frigate/recordings/2024-09-03/09/Foscam/41.34.mp4 in 0.1179051399230957 seconds." etc.
I have live streams, i have previews, no other errors on log only "info". Even the .mp4 files which are prefectly recorded to a share are fine and i can view them if i mount the share and use VLC etc.
But if i click on a event the http://x.x.x.x:5000/review page opens and the first frame of the video shows a loading icon which never finishes.
Even then. No errors in Log. Only:
"GET /api/preview/all/start/1725267600/end/1725357600 HTTP/1.1" 200 7622 "http://192.168.1.6:5000/review" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/127.0.0.0 Safari/537.36" "-"
And nothing happening.
I already read a seemingly simmilar issue which was mainly about transcoding and using go2rtc but i can not get this to work and on the other hand the browser should be perfectly fine to load and show an .mp4 file or am i wrong?
Do i miss somehting?

Commented the go2rtc lines out because it was not working, but here is my atm working camera config:

# go2rtc:
#   streams:
#     Foscam: ffmpeg:http://192.168.1.77/videostream.cgi?user=admin&pwd=password

It seems the browser is failing to play the recordings, you can check browser logs as well as maybe try different browsers

Had to edit the IP, there was a 50 in it. But after changing that here is the outcome:



Thats okay?

[NickM-27]

ah yes, so here is the problem. Your cameras are mjpeg. I don't have any idea how the recordings are even working, but they need to be h264. See the docs https://docs.frigate.video/configuration/camera_specific#mjpeg-cameras

So since there is no rtsp stream but this http stream I can use in Frigate I thought this should be okay. But now that you pointed this out it seems quite clear. Is there a way to transcode this or do I have to buy new cameras? I just need a little hint where to search for. Thank you alot!

edit: okay, followed your link and read about go2rtc restream and so on will try this out! Thx!

[NickM-27]

the docs I linked show exactly how to do that

Did everything like it was shown in the Docs, now everything is working. GPU is now on 5% usage and not on just 1% but this is not having any effect on the CPU temps etc. so that is fine and at least it shows that the iGPU is used correctly. Thx for the help! Really appreciate this! It is not that common in todays world. All the best to you!
