Posted: Fri Mar 09, 2007 11:36 am Post subject: [Asterisk-video] app_transcoder
Hi all..
I have just added a first (and early version) of a video transcoding application.
Currently only MPEG4 to H263 is working which will be needed if you plan to
test the app_rtsp application with a network camera, but i hope to have H263 to H263
for use with h324m gateway and been able to bridge a 3g videocall with a video
softphone.
I also still have to implement a better bitrate control and handle default parametes so
it doesn't segfault when one is missing... :)

uhm...
Asterisk can build the app but cannot start it:
CLI> load app_transcoder.so
[Mar 12 12:29:28] WARNING[16670]: loader.c:362 load_dynamic_module:
Error loading module
'app_transcoder.so': /usr/lib/asterisk/modules/app_transcoder.so:
undefined symbol: av_realloc
uhm...
ld path is ok, since app_mp4 and libh324 that're on same libavcodec
path works ok....
any hint?
Greetings,
Matteo
P.S. I've here an axis netcam that handles rtsp. With ffplay and mplayer
I can see it, so I think will be no probs...

My app_transcoder.so doesn't have the av_realloc symboll, could you check
your're using the correct avcodec.h file?

the problem was int not having the shared libs.
I enabled them in ffmpeg and now starts ok.

seems that the transcode app does not like something.

I tried with a video softphone.
The app exits with a segfault after calling app_rtsp
(and app rtsp does nothing)
Here's the gdb log:
