[Mjpeg-users] Errors with compile
Hello all, Brand new user here, had no idea these tools even existed til a few days ago when I bought my DVD player and decided I wanted to see if I could encode some of my DivX movies to SVCD. Good news is, I can. However, I am using Mandrake with mjpegtools-1.6.1-9mdk, and the script I use, mencvcd, takes about 24 hours to encode a 700MB DivX to VCD on my aging P3 866 with 392MB RAM. When I originally tried to compile mjpegtools from source, I was warned that without nasm, performance would be very poor. So I installed the Mandrake nasm package, and proceeded to build. ./configure goes ok, but when I try to 'make' I get this error: /home/joehill/tmp/ccdc9rev.s: Assembler messages: /home/joehill/tmp/ccdc9rev.s:625: Error: symbol `NOT_SUPPORTED' is already defined make: *** [jdapimin.o] Error 1 I read the install instructions carefully, and I believe I have all the required software installed, I am not sure what this error means (actually, this error comes up both when I try to build mjpegtools *and* when I try to build jpeg-mmx). I would like to see if I can improve the speed with which SVCD's are encoded, if I am barking up the wrong tree, please feel free to slap me with trout.

No, there was a bug in configure.in that caused autoheader to never be run. I have checked in the fix. You can, temporarily (until Sourceforge catches up in a couple hours) work around the bug by running 'autoheader' manually. Then config.h.in will be generated and ./autogen.sh will work. That worked.

Of course ;) libtool-1.5 is, apparently, now a requirement. The --tag capability is from libtool 1.5 and was needed for building the shared libraries (the core of the encoder is now a shared lib that can be used by other programs). libtool-1.5 is much better than 1.4.x (especially when C++ shared lib building is involved - and on OS/X 10.3 libtool-1.5 comes pre-isntalled and integrated which helped me a lot on that system). The newer version of libtool has not introduced any compatibility problems at all for me (on any of 3 or 4 different operating systems) so my suggestion would be to install libtool-1.5 Good Luck!

It's the management of this depends on that, so build that, which As the toolbox is becomes more complete the management gets simpler. depends on the other so build the other and so on and so forth (like my current fight with mpeg4ip -- all kinds of gripes from automake/autoconf, etc.). It's just so much easier when the distro strange - given recent vintage automake/autoconf/libtool tools it should have been a simple matter of ./cvs_bootstrap and make. The bundled version of the SDL is the only thing that gave me a struggle on one of my systems (heck, even got mpeg4ip to build on OS/X except for the mp4player program which the developers tell me wouldn't work on OS/X anyhow. but mp4creator and other programs run ok and I find them easier to use than Apple's gui programs for manipulating Quicktime files). Not even to mention the mess of a system you wind up with when you can't track the origin of a given file (like you can for example when you do an rpm -qf `which mpeg2enc`). I've got 600+ files in /usr/local/lib and know where everything came from ;) Welcome! Uh, mpeg4ip is a big project - useful to have though. So I am discovering. I am going to attempt to build just mp4creator and see if it's useful before I try to build the whole beast. Down that path lies a bit more madness than you've already encountered. As I recall from talking to the creators of the project you'll need a couple of the shared libs such as libmp4v2 and libmp4av at least - so you can try building those first, then into the server/util directory, there are some very useful utilities in that (and of course the mp4creator program). Once the ./configure problem(s) are taken care of it's as easy to build the whole thing with 'make' than it is to pickchoose. Right. I agree. But I want to clarify if you are asserting that mpeg2 only belongs in a (trying very hard to not use the term STB) dedicated hardware device (and not on a software device) or if that is just the Not at all. At the moment MPEG-2 is most useful on standalone hardware players simply because there are no units (not quite true - I think there are 2) that handle anything else. You can't put MPEG-4 onto a DVD, take the disc and go into Circuit City (or wherever) and expect it to play on anything except a computer. But are you asserting that mpeg2 should not be used in a computer running software to be the equivalent of an STB (i.e. No. Feel free to use whatever suits your fancy on your computer. For DVD sized data I use MPEG-2, for the smaller resolutions I might use MPEG-4. MPEG-4 does better at the lower bitrates (smaller files) than MPEG-2 though so if smaller files (to get under the 2GB limit) is the goal then MPEG-4 is a better choice. Once you get up around 4Mb/s there's nothing really to be gained with MPEG-4 - the files are just as big their MPEG-2 counterparts. One drawback of MPEG-4 at the present time is that at the higher resolutions the current software decoders begin using a lot of cpu. MPEG-2 decoders are more mature and there are hardware assists - some video cards have MPEG-2 decoders built in and the nVidia one I'm using comes with libraries that ffmpeg/mplayer use to talk to the hardware decoder (only works for MPEG-2 though). By the time you get up to the HDTV (1920x1080) size even a 3GHz cpu was down in the low single digit frames/sec range (at least in the one test that one of the video magazines ran) when playing back MPEG-4. At one time there was mention of MPEG-4 being used for the HD-DVD format but that seems to have faded in favor of MPEG-2 and different lasers. Patent issues and/or greed I think are what effectively relegated MPEG-4 to niche areas (and geeks). Agree. It's analog cable however, and not very clean at that. Ah, ok. Digital cable can be quite a bit cleaner but it's not as widely available. options to ffmpeg/mencoder that will allow the use of a considerably Yeah, I know. But unfortunately I don't understand enough about video encoding to understand (some of) them. They are also not very well documented. '-vf hqdn3d,trell' are two that come to mind. Mencoder can do the cropping without a speed penalty Right. ISTR that I lower the bitrate when I crop. I know I do when I The other thing that can be done is to downscale. Mplayer (perhaps ffplay as well) know how to deal with the coded frame size being different than the
