1.31.42 Camera Pass through

[gsaindon]

Hi,
Camera pass through seems to work with trendnet cameras but not with dahua. Here is what I get in the log file:

Thanks,

Ok, found the problem. Audio codec must be set to AAC. Now only problem left is that after a zoneminder restart, the first event is viewable but not the subsequent ones.

Thanks,

I'd really like some more detailed logs, with debugging turned on.
Please set debug level to 4.
the code SHOULD re-encode whatever the camera sends to AAC. Works for my cameras that send pcm audio.

[gsaindon]

Pretty weird but it seems to be working now. I'll do more testing and try to figure out what solved it.

How did you set the audio codec to AAC? (camera or within zoneminder settings someplace)?

[gsaindon]

Hi, the setting was on the camera

[amritgary]

thank you.. for some reason i am unable to get audio to work with unless it encode it into AAC using cmdline options.
