can not import audio files

[delectate]

archlinux with audacity 1.3.12 & ffmpeg SVN-r24953 (--enable-shared )

audacity can recognize ffmpeg libs,but still can not import ape files. ffplay ,ffmpeg ,mplayer works on my pc.





I have no idea what to do, anyone help?

[Gale Andrews]

Please note that Audacity doesn't officially support latest svn FFmpeg, only 0.5.x.

I only have one .APE File to hand but it imports fine using FFmpeg 0.5.x on Windows 7 and Ubuntu 10.04.

I suggest you convert the .APE at the command line in svn FFmpeg and see if there is a problem there:

$ FFmpeg -i song.ape song.wav

If FFmpeg refuses it at the command line, check the validity of the file and if it seems correct, report it to FFmpeg.

If the file converts to .WAV, you can then import it into Audacity. In that case please upload the .APE file to a free file transfer service such as:

http://www.yousendit.com
http://www.megaupload.com
http://www.sendspace.com

and give us the web address where we can download it. Also show us the contents of Help > Show Log - FFmpeg errors are stored there.

thank you very much.

[Gale Andrews]

Thanks for the sample file - it imports fine with Audacity 1.3.13 on Windows 7 using FFmpeg 0.5.

Is the Audacity 1.3.12 from the ArchLinux repository or have you compiled the Audacity 1.3.12 source tarball using these workarounds for SVN FFmpeg? I don't really understand "(built against 0x342000 - 52.32.0)" (i.e an earlier version of FFmpeg) in your log.

When you say you can import APE files before, in what version of Audacity/with what version of FFmepg did that work?

Does Audacity import other formats requiring FFmpeg, such as AC3 or WMA, or is the problem only with APE files?

1.3.12 does not support FFmpeg > 0.5 without hackage. Does "Soft installed from updated portage tree" mean you got the Audacity e-build from http://gentoo-portage.com/media-sound/audacity, in other words using the gentoo FFmpeg patch listed in the e-build? If so, have you reported the issue to Gentoo ?

Certainly compiling Audacity SVN HEAD on Ubuntu 10.10 with this patch, using the repository-supplied FFmpeg 52.72.2, 52.64.2, 50.15.1 (i.e > 0.5), I can import supported files into Audacity using FFmpeg.

Steve if you are reading, do you use latest git FFmpeg with SVN HEAD on Ubuntu 10.10?

Steve if you are reading, do you use latest git FFmpeg with SVN HEAD on Ubuntu 10.10?

So far I've only used FFmpeg with Audacity 1.3.12 (both from the Ubuntu 10.10 repository).
I've not investigated Audacity 1.3.13 with FFmpeg. Would you like me to?

I know that 1.3.13 alpha works with the 10.10 repository build of FFmpeg OK, when compiled with the patch noted above in post 6.

I don't know much about building FFmpeg, I'm afraid. I got FFmpeg 0.6.1 and it compiled fine with ./configure and make, and I installed it. I haven't recompiled Audacity yet. However the FFmpeg build doesn't produce a libavformat.so.* file. Perhaps it doesn't need to?

I'm just now testing with FFmpeg from the current nightly.
The default ./configure creates a static build of FFmpeg which does not have .SO files.
I've built with the --enable-shared option, then the .SO files are produced.

I modified Audacity using the instructions here: http://manual.audacityteam.org/index.ph ... tallffmpeg

...
Workaround: change src/FFmpeg.cpp line 207 from "static int ufile_write(URLContext *h, unsigned char *buf, int size)" to "static int ufile_write(URLContext *h, const unsigned char *buf, int size)"
...
Workaround: Re-compile Audacity and change all instances of "match_ext" in ../src/FFmpeg.h and ../src/FFmpeg.cpp to "av_match_ext".

I did not use the AAC workaround as --disable-encoder=aac does not appear to be a valid option.

AAC exports will be incorrect unless you disable the built-in AAC encoder (--disable-encoder=aac).

The current nightly version of FFmpeg has been recognised and other than AAC (which does not appear to work correctly) all seems well.

[steve]

Update:

I'm getting crashes with WMA import and export with 1.3.13, but not with 1.3.12 (both using the same nightly build of FFmpeg).
I'll have a go building Audacity with that patch and see if that works any better.
