Arch Linux

Compiling the source package produces a binary that works with audio. You have to change 'shmstr.h' in capture.c to 'shmproto.h' for the compile to work.

The patch to replace the extension header is already applied, that's done by the xextproto-7.1.1.patch. So the difference lies within the installed packages, I have to build packages for the repository in a clean chroot, but even if I build it at my system, I don't get the audio stuff enabled.

Please give me a list of the packages installed on your system to narrow the range of packages - that probably provide the needed files and have to be tested - down.

Also please tell me the version of your installed ffmpeg package and if you have modified it, as the configure scripts says "checking for avcodec_decode_audio in -lavcodec... no" when I build the package. (libavcodec is part of the ffmpeg installation.)

hi,
I downloaded xvidcap from sourceforge and compiled it. My installed ffmpeg version is "ffmpeg 20100108-2". But I think when I compiled xvidcap from source, it built its own ffmpeg ( with static linking perhaps -- i am not an expert -- but the size of the binary is much larger than that of the pacman installed version) as shown in the output of configure:

Please let me know whether you need any other info. You have probably seen this already : http://bugs.gentoo.org/show_bug.cgi?id=258042

Also https://bugs.launchpad.net/ubuntu/+source/xvidcap/+bug/375711. As I said, I am not very much familiar with all this and basically just follow instructions.

So you are building against the ffmpeg delivered with the xvidcap source code that was the problem for ticket  FS#17915 . Also when building against this ffmpeg the compiler already states that the functions 'av_fifo_init', 'av_fifo_write' and 'av_fifo_read' are deprecated.

These methods have by now been dropped:
http://git.ffmpeg.org/?p=ffmpeg;a=commit;h=86e5d7ad2036d6e06ceec7ea41279669a16172db
http://git.ffmpeg.org/?p=ffmpeg;a=commit;h=dbe69b900b8d9b3d057b2783d204451a6eaef6ae
http://git.ffmpeg.org/?p=ffmpeg;a=commitdiff;h=9f8370a9dea5f778c14ba94ca154faf1cf7749e5

So basically xvidcap uses old ffmpeg code. I'll set the severity of this bug to "low", try to patch the code within the next 36 hours and will then write an upstream bug, either with the patch or just as an update request. If you want to reproduce this, take the files from ABS and include the 01configure.diff from ticket  FS#17809  as patch.
