ffmpeg bringing me down

[worker201]

I've been trying to build ffmpeg from source on my FC3 box. It fails, with the following error message. The users of the ffmpeg mailing list are ignoring me. So I installed the ffmpeg and ffmpeg-devel packages with synaptic. Then, I attempted to build avifile from source. It requires the ffmpeg libraries, and it ran into the same troublesome junk as building ffmpeg did. If anybody can tell me anything about how to get this darn thing to work properly, I would be very pleased. ffmpeg has to work in order to get transcode to work. And transcode has to work before dvds will be authored.

Please, help me!!!!!!! This is ruining my month.

You couldn't rebuild using the SRPM as I suggested in your previous thread? Can you give me an example of where transcode fails so I can duplicate the problem and build you an RPM that works (assuming it's just compile option differences)?

Regarding your specific error I would assume you don't have a52dec-devel installed (apt-get install a52dec-devel).

Here is the output I have been able to get from the version of transcode available from synaptic. The mpa codec referenced here, as far as all internet research can explain, is part of the mp2 codec. The command 'ffmpeg -formats' claims that this codec is enabled, however, transcode cannot tell. I wanted to give the beta version of transcode exact links to the correct libraries during configure. So I guess what I need is to have the exact libraries built correctly somewhere. And apparently those are libavformat.so and libavcodec.so.

What command line did you use to produce that output?

[worker201]

Sorry, got clipped in my copy/paste:

transcode -i rogue2.avi -y ffmpeg -w4500 --export_prof dvd-ntsc --export_asr 3
-o rogue2 -D0 -s2 -m rogue2.ac3 -J modfps --export_fps 29.97

Ok, I have some AVI files and I can duplicate the problem. I will do some research and see what I can come up with.

[Void Main]

I haven't got an answer yet for transcode but I am about to start looking into it. Are you sure you can't accomplish what you need using tools other than transcode? For instance, I use lxdvdrip and I recall not being able to use transcode but it gives you a couple of other options like "streamdvd" and "mplayer". I have mine set to use "streamdvd". Maybe if I get transcode fixed I might be able to use it to. I guess my point is, there might be other ways to get what you want using other tools.

[worker201]

I would use some other tools, but I am not familiar with any of them. If I had the original moviefile available, I would just attempt to re-rip it with the encoding I wanted. Guess there's plenty more research for me to do.

[worker201]

I downloaded a program called avidemux which seems to work okay. It accesses ffmpeg too, but it doesn't seem to have a problem finding the right codecs. Hopefully, this will work. It's not really a command line program, and it's not really a gui program either. When you invoke it from the xterm command line, it opens a gtk window, which has the usual features. But it also produces output to stderr, the terminal window that spawned it. Pretty cool, it's kinda like setting a gui-based program to verbose mode or something.

[Void Main]

Cool, I spent quite a bit of time last night trying to figure it out and I just haven't had time since. I will be busy all weekend doing other things as well so I hope you can get that working.

[worker201]

I finally managed to get transcode 1.0.0beta3 working, using the freshrpms ffmpeg package. Here's the configure line that worked:

Code: Select all

./configure --enable-mmx --enable-sse --enable-sse2 --enable-freetype2 --enable-lame --enable-ogg --enable-vorbis --enable-theora --enable-libquicktime --enable-a52 --enable-libmpeg3 --enable-libxml2 --enable-mjpegtools --enable-imagemagick --with-libavcodec-includes=/usr/include/ffmpeg

And of course, the following CFLAGS:

Code: Select all

export CFLAGS="-O2 -fomit-frame-pointer -mmmx -msse -mfpmath=sse"

Of course this assumes you have a Pentium 4 and all the enabled programs installed correctly. The key is the --with-libavcodec-includes portion, since transcode assumes the includes are in /usr/bin/ffmpeg, and that's not where FC3 rpms drop them.

Still not sure why ffmpeg won't build, but that's now a spare-time problem.
