Yes, I'll do some tests (which version of x264 are you using?). Most likely the problem is on how the x264 encoder is feeded. > - Using lavc module, it seems to run OK, except that 2-passes > rendering does not work, as the first pass does not seem to record > anything in the log file.

This is a known "issue" in the sense that ffmpeg(/lavc) module should _not_ expose all possible setting, but just a subset that is shared wit all native ffmpeg codecs. It's the job of specific x264 module to provide full access to underlying library. > - the lafc muxer did not accept to mux an AAC stream created by the > faac module in a m4a file, for some reason.

That module is still HIGHLY experimental, it's already a success if hasn't caused a segfault! :^) > Please let me know if you want me to run some tests to fix these > problems or, if they're caused by my ignorance, please explain where > I've made a mistake.
