avoid using ffmpeg version 0.4.9pre

[johncooper]

I had problems generating video at anything less than 10X. I read another post where a user with the same issue downgraded to version 0.4.8 with success. I downgraded to 0.4.8 and now I can generate videos error free in real time. If you find MPEG1/2 doesnt support 5/1 fps in zmvideo.log try using version 0.4.8. I am using debian testing/unstable and apt-get grabs version 0.4.9pre so I apt-get removed ffmpeg first to stop any updates from overwriting and then downloaded version 0.4.8 from sourceforge and compiled from source. mpeg streaming of monitors is still not working which really is not a big issue as jpeg streams via cambozola work well enough.

Interesting. Have you tried the CVS version of ffmpeg as it's possible that may have fixed the issue.

No I didn't try the CVS version. Would have been nice if the version fetched by apt-get worked to reduce the need for manual updates but I suppose thats the price paid for running testing/unstable, I'm sure if I were running stable then apt-get would have fetched an earlier proven version. I switched to testing/unstable in order to apt-get the latest X server with drivers for my Radeon graphics card using 3D acceleration. One more reason to use Nvidia rather than ATI!!! I haven't run zoneminder since 0.9.15 and I just want to say GOOD JOB on 1.20.1, works great even running on the same box with Asterisk.

I got similar problem when I upgrade to ffmpeg 0.4.9 and solved by upgrading all dependencies package of ffmpeg.

I have been having the same problem as John. Video generation fails unless you increase the speed until zm tries to generate at or above 25fps.

You can use apt to install the previous version however using the following command:

Code: Select all

apt-get install ffmpeg=0.4.8

If you're running Fedora you can still use apt. There is a useful HOWTO here.
