upgraded libs broke code again..

[reza]

Seems like the latest version of ffmpeg (ffmpeg-devel-0.4.9-9_cvs20050517.rhfc3.at) breaks the code.

The struct AVCodecContext changed. The entries frame_rate and frame_rate_base are no longer there, but replaced with something called pts which really isn't defined. Here's the line from /usr/include/ffmpeg/avcodec.h

Code: Select all

    /**\
     * presentation timestamp in time_base units (time when frame should be shown to user)\
     * if AV_NOPTS_VALUE then frame_rate = 1/time_base will be assumed\
     * - encoding: MUST be set by user\
     * - decoding: set by lavc\
     */\
    int64_t pts;\

I commented out

Code: Select all

                //c->frame_rate = frame_rate;
                //c->frame_rate_base = 1;

from zm_mpeg.cpp to get zm to recompile. Any thoughts?

Thanks for highlighting this. I'll take a look.

Hi,

i just commented out the two line mentioned above.
But now i get another error:

Any Ideas?

Looks liek the AVCodecContext might have been misdefined somplace. I stopped upgrading ZM as it seems to break every time I do.

Hi Zoneminder,
Did you ever figure this compile problem out? I get the same exact errors on FC4, trying to compile zm 1.21.3 with ffmpeg from cvs as of last Sunday.

How do I get around the problem?

thanks
rj

[zoneminder]

The ffmpeg interface changed a while back. I have a version of ZM that works now with the cvs version of ffmpeg. It's not released yet but will be very shortly.

Am I right in assuming that building is broken again? zm 1.21.4's release notes suggest that this problem has been fixed, but I'm still seeing

zm_mpeg.cpp:102: error: 'struct AVCodecContext' has no member named 'frame_rate'
zm_mpeg.cpp:103: error: 'struct AVCodecContext' has no member named 'frame_rate_base'

Is there a fix for this (quick or otherwise)? I was going to browse through CVS but I've had no luck finding the repository for zoneminder.

[zoneminder]

1.21.4 seems to be broken with respect to ffmpeg 0.4.9-pre1. However 0.4.8 and the cvs release (of ffmpeg) are fine. I would recommend the latter.

1.22.0 works with all (so far) ffmpeg versions.

I might try upgrading. if things break, i'll be unhappy and sad.

mmmmmmmmmm, 1.22.0..

woohoo!!!

[daveparker01]

I'd like very much to try this 1.22.0 - I've hit the wall on my FC4 box trying to get an ffmpeg to build that's ostensibly compatible with zoneminder.

The problem is that, given the gcc version I have, ffmpeg 4.8 simply will not compile. And none of the repositories I've got in apt have anything older than 4.9. It's really a nightmare - I've spent many hours just trying to get ffmpeg 4.8 to build. From what I've been able to gather, it's b/c of some known issue with gcc4.

I'd be very overjoyed to have the opportunity to try zm 1.22.0

I'm hoping that zm will support my v4l2 device (which motion pretty much does not afaict).

[zoneminder]

Are you saying that the ffmpeg cvs version doesn't compile either, or that it won't link with ZM or neither?

If all you want to do is see if your card works then you can install ZM without ffmpeg as it's not critical for the basic functions.

Hi.

Have you tried to check-out the latest CVS version of FFMPEG, and compile it? It should be compiled fine on GCC 3 and 4.

[kbuytaert]

I have the same issue on Fedora Core 4.

I can't find any prebuild rpm's either ..
Anyone ?

greetings
