Hi, Ben gcc version is: 4.7.0 clang version is: 3.2 The command options are: 1) clang generated object files: clang -O3 -c *.c -o x.o link: clang *.o -lm -o mpeg2enc 2) gcc generated object files: gcc -O3 -c *.c -o x.o link: gcc *.o -lm -o mpeg2enc Yes, maybe it is the config introduced problems, I build it with enable debug options.

Hello, all When I compile mpeg2enc of Mediabench, it seems clang and llvm take longer time than gcc. I meausre the time as follow: gcc -O3 8.190s clang -O3 20.253s will this means clang and llvm are slower than gcc in compiling c code.

The timings are useless without information about the ve...

Hey all, I've been using the example reference encoder that comes with Theora reference implementation from SVN, but there are very few options to tweak encoding parameters in contrast to other codecs utilities such as x264, mpeg2enc, etc. Is there a way to access more advanced encoding parameters for Theora without having to dig into the source itself and make my own custom encoder app? Not that that would be a bad thing in the long run, but I am not sure I'm that ready for it...

My first guess about the problem would be that the programs want to process the stuff in a different order, e.g. mplayer wants to output some sound before anymore video and encoder_example wants to receive some video before anymore sound. This could easily depend on the order of stuff in the file mplayer is reading. I guess something similar could happen for opening the pipes as well. The

I did a little poking about with the pcm-from-fifo problem I was having... What I'm attempting to do is an on-the-fly export from one file using mplayer to generate yuv4mpeg video frames and pcm audio, piped through fifo's. This DOES work with mpeg2enc/mp2enc, so I'm assuming it's not a problem with, e.g., my filesystem... the example encoder appears to successfully open and begin reading the audio stream, but 'hangs' there. I just ran a test using strace on the example encoder, and it appears to be hanging after determining the...
