Repeated error message:

[jogo]

I am getting repeatedly error messages related to a certain camera like

I am not sure whether this is related to Zoneminder or the camera, which happens to be one of the more expensive Hanwha cameras. Other Hanwha cameras do not produce these messages (afaik).

There was a similar sounding thread recently. Think it was the ffmpeg version behind it in the end.

Good time of day.
I had exactly the same error with 4 cameras. The program version is 1.36.33.

In ffmpeg 4.8+ we started seeing out of order packets coming from decoding. Problem is when writing out to mp4, they need to be in order. So we now need to buffer them and sort them.

You can set a parameter in Encoder options, reorder_queue_size= to turn on this buffering. Testing seems to indicated that for most people setting it to keyframe interval or 2*keyframe interval should do.

In 1.37 we automatically detect the need and size, but in 1.36 you have to set it manually.

Hi Isaac,

thanks for your strong job.
Please, note that in the "proposed" repo 1.36.34 version is not available for jammy, focal, bionic, xenial.
Something went wrong in the build process.
thanks

Ok, I have a few more fixes in there now, will push another release
