[Solved]: No Audio or no Eventvideos

UPDATE: Solved Config attached, issue is solved

Describe the problem you are having

_I have my first H264 camera (called Sauna) and therefore I could not use the configuration from the previous H265 camera. Everything worked fine (except for some spam in the log) until I noticed that the event videos had no sound. The camera streams on the main stream H264 4k+AAC Audio. On the substream it is currently set to video only with no sound.

Unfortunately, adding the default Output_Args and replacing -an with -c:a aac does not work.

That’s when the struggle started.

With the current settings 30 seconds recordings are only 1 second long and consist of very few frames. One from the beginning of the event, one in the middle and one as the person leaves the scene again. There is now also audio in this 1 Second Videos , but not usable, due to the duration and compression.

What do I need to do to get this H264 stream with AAC audio to process and save the clips correctly?_

Regarding the Output I have tried to remove the copy argument from record for the NC-800-1 Cam, but then I get this Log:

[WorthyAttempt]

Try changing record output to read -c:v copy -c:a aac. This was updated in the FAQ section https://docs.frigate.video/faqs, however has not been updated in the config reference file https://docs.frigate.video/configuration/index#full-configuration-reference.

I am by no means an expert at this so could be incorrect, however you also define elements at camera level that a) are default values so could possibly be omitted? and b) can be defined at a global level to reduce repetition and simplify config file.

[Larosen]

I have now the following output arguments: record: -f segment -segment_time 10 -segment_format mp4 -reset_timestamps 1 -strftime 1 -c:v copy -c:a aac I am gonna report back if the audio is working as soon as possible. You are right with the defined values at camera level. Due to the C800 which is a H265 Stream and the NC800 which is H264 I am quite unsure what needs to be global and what is local with more H264 cameras on the way I am probably going to define the H264 as global arguments

Can you please update if this resolved your issue?

Issue is solved, thanks to you and the new config is now attached at the origial posting. Thank you very much for the help 😃
