punk_ecas · Post by **punk_ecas** » Fri Mar 13, 2009 12:27 pm

Please, post your feedback of trying to install zm with this ffmpeg version, because i'm not getting ffmpeg working, after install it i type ffmpeg on command and get:

Code: Select all

ffmpeg: error while loading shared libraries: libavdevice.so.52: cannot open shared object file: No such file or directory

And compiling zm i get

Code: Select all

zm_local_camera.cpp: In function â€˜PixelFormat getFfPixFormatFromV4lPalette(int, int)â€™:
zm_local_camera.cpp:161: error: â€˜PIX_FMT_VDPAU_H264â€™ was not declared in this scope

I'm not sure about the first part of your error but the second part is covered here. If you used a newer ffmpeg you wouldn't see the errors while building zoneminder but then you lose features.

Please see this post,

http://www.zoneminder.com/forums/viewto ... sc&start=0

About 10 posts down you will see your error and then I show a solution. After you edit the file and build zoneminder again you'll probably see another error which again is covered at that post. Just edit the next file if it failes to build according to what I wrote and then build it again. You'll get it working eventually, just not sure what that error at the command line is.

Thanks for the solution.

But commenting those lines which funcionalities i'm loosing??
And what about changing zm_rtsp.cpp to av_alloc_format_context() function?

That work, but i affraid to missing some important issues.

About ffmpeg, i don't really know what to do.

Honestly I don't think you'll lose any functions. It's just the numberous differences in Zoneminder builds and ffmpeg. You should be ok, it's the same setup I have on that online demo.

Ok. I have almost everything working, using a guide i have hacked together. I'm trying to put the finishing touches on it, and I have ONE issue left. Hopefully someone can help.

The last issue that I am coming across is that I cant generate videos from events. Everything configs and compiles fine without any issues (i did however change like 183 of zm_rtsp.cpp from avformat_alloc_context to av_alloc_format_context)

When I try to generate an video from an Event, this is in the ffmpeg.log file:

Code: Select all

/usr/local/bin/ffmpeg: symbol lookup error: /usr/local/bin/ffmpeg: undefined symbol: avformat_alloc_context

Whats weird is that if I run ffmpeg as both root and www-data users, this is the output:

Code: Select all

FFmpeg version SVN-r17945, Copyright (c) 2000-2009 Fabrice Bellard, et al.

Does anyone know where this might be coming from? I have a pull from ffmpeg svn this morning around 9:30a. I cant attach a file, but if you want a working copy of the guide i am using, let me know and I will post it somewhere.

Even more interesting...

zmvideo.pl runs from the command line just fine as root and www-data and generates a video.

Can you stream in mpeg instead of jpeg?

jsylvia007 · Post by **jsylvia007** » Fri Mar 13, 2009 4:13 pm

Damn. That would be a no.

punk_ecas · Post by **punk_ecas** » Fri Mar 13, 2009 4:15 pm

Did you try the version of ffmpeg that newvisionantenna posted above?

jsylvia007 · Post by **jsylvia007** » Fri Mar 13, 2009 4:19 pm

I'd rather stick to the SVN version, but I suppose I could try that version out.

I try that version but i get:

Code: Select all

ffmpeg: symbol lookup error: /usr/local/lib/libavcodec.so.52: undefined symbol: av_lfg_init

And i can't fix this yet.

Is there a developer around who can explain the difference between me executing zmvideo.pl from the command line and how zoneminder executes it?

ffmpeg works from the command line. Why cant I view mjpeg streams or create videos?

newvisionantenna · Post by **newvisionantenna** » Fri Mar 13, 2009 5:03 pm

The version I put up is from the SVN tree. It's alittle older but works. What browser are you trying to generate video's with? If it's IE7 or Google Chrome it won't work and will give you some error. Try Firefox and click the generate video button, have a feeling it will work just fine.

jsylvia007 · Post by **jsylvia007** » Fri Mar 13, 2009 5:09 pm

All i use is Firefox. I'm still getting the same issue.

I can use zmvideo.pl just fine, but mjpeg streaming and video generation of events fails.

This is the error in the ffmpeg output now:

Code: Select all

/usr/local/bin/ffmpeg: symbol lookup error: /usr/local/lib/libavcodec.so.52: undefined symbol: av_lfg_init

My hunch is something is getting screwed up in the pathing when zoneminder calls the functions, because ffmpeg works completely fine from the command line.
