libvpx.so.6 missing

(1/2) > >>

pppqq:
I installed  ffmpeg for tinyCore vs 14.1

I get the following when try to use ffmpeg :


--- Quote ---ffmpeg: error while loading shared libraries: libvpx.so.6: cannot open shared object file: No such file or directory

--- End quote ---

The strange thing is that it was working yesterday so maybe another package loaded it.

Hi pppqq
Based on your last thread, you are running armv7:
https://forum.tinycorelinux.net/index.php/topic,27508.msg177261.html#msg177261

libvpx.tcz for armv7 contains:

--- Code: ---/usr/local/bin/vpxdec
/usr/local/bin/vpxenc
/usr/local/lib/libvpx.so
/usr/local/lib/libvpx.so.8
/usr/local/lib/libvpx.so.8.0
/usr/local/lib/libvpx.so.8.0.0
--- End code ---
Found here:
http://tinycorelinux.net/14.x/armv7/tcz/libvpx.tcz.list

libvpx.tcz for armv6 contains:

--- Code: ---/usr/local/bin/vpxdec
/usr/local/bin/vpxenc
/usr/local/lib/libvpx.so
/usr/local/lib/libvpx.so.6
/usr/local/lib/libvpx.so.6.2
/usr/local/lib/libvpx.so.6.2.0
--- End code ---
Found here:
http://tinycorelinux.net/14.x/armv6/tcz/libvpx.tcz.list

The  .info  files show the armv7 version was updated more recently:
http://tinycorelinux.net/14.x/armv6/tcz/libvpx.tcz.info
http://tinycorelinux.net/14.x/armv7/tcz/libvpx.tcz.info

ffmpeg in both repos is the same.

Hi pppqq
I just checked ffmpeg for dependencies:

--- Code: ---tc@E310:~/ffm$ readelf -d mnt/usr/local/bin/ffmpeg | grep '(NEEDED)'
 0x00000001 (NEEDED)                     Shared library: [libavdevice.so.58]
 0x00000001 (NEEDED)                     Shared library: [libavfilter.so.7]
 0x00000001 (NEEDED)                     Shared library: [libavformat.so.58]
 0x00000001 (NEEDED)                     Shared library: [libavcodec.so.58]
 0x00000001 (NEEDED)                     Shared library: [libpostproc.so.55]
 0x00000001 (NEEDED)                     Shared library: [libswresample.so.3]
 0x00000001 (NEEDED)                     Shared library: [libswscale.so.5]
 0x00000001 (NEEDED)                     Shared library: [libavutil.so.56]
 0x00000001 (NEEDED)                     Shared library: [libm.so.6]
 0x00000001 (NEEDED)                     Shared library: [libpthread.so.0]
 0x00000001 (NEEDED)                     Shared library: [libc.so.6]
--- End code ---

It doesn't depend on libvpx, but its dependency libavcodec does:

--- Code: ---tc@E310:~/ffm$ readelf -d mnt/usr/local/lib/libavcodec.so | grep '(NEEDED)' | grep vpx
 0x00000001 (NEEDED)                     Shared library: [libvpx.so.6]
--- End code ---

I suspect the libvpx might need to be rolled back.
The following dep files include libvpx:
gst-plugins-good.tcz.dep
libavcodec.tcz.dep
libvpx-dev.tcz.dep

Let's see what Juanito says.

GNUser:
In the meantime pppqq could try the statically-built ffmpeg available here:
https://www.johnvansickle.com/ffmpeg/

I believe for armv7 he would download the armhf build.

I removed extension for libvpx and installed gst-plugins-good. This showed a download of libvpx.

looking in /usr/local/lib/ there is libvpx.so.8 but no libvpx.so.6
