following the threads on the "Users" mailing list with great interest and was interested in trying the CVS version to gain access to some of the newer features. I did a checkout of the mjpeg_play module, then used the autogen.sh, after which I invoked make.
No problems running the ./autogen.sh script? Some folks seem to have a very difficult time getting past that step.
No problems at all
There didn't seem to be any problems with the compile, but when I tried to use mpeg2enc, I keep getting the following error:
"Malloc failed"
Hmmm, you didn't accidentally set a memory limit with the shell's "limit" command did you? Something like "limit data 16m" would cause a problem.
Nothing like that. Older versions of mpeg2enc work just fine.
After looking at the code, it seems that it is failing at the following place in encoderparams.cc:
motion_data = (struct motion_data *)malloc(M*sizeof(struct motion_data)); if (!motion_data) mjpeg_error_exit1("malloc failed");
That structure is not huge so the memory allocation limit must have been reached earlier for an unknown reason.
I have not run a make install on the CVS version yet, as I wanted to make sure that there were not any problems before I put it into "production", so I am running the binary from ~/mjpeg_play/mpeg2enc. Could this be the source of the problem?
It could be part of the problem - the latest version of mpeg2enc
does have a shared library now.
Thing to try is doing the make install to get all the new .a and .so and .h files installed. Then do a make clean and make again - I still have the nagging feeling that during a build the previously installed files can be consulted/used (depending on the compiler and the order of the -I and -L flags used).
I did all of that, and am still getting the same error at the same place. Any more suggestions?
I am using gcc 3.0.4 with Linux Kernel 2.4.18-6mdksmp
Thanks, Gene
