Ah, damn, I've already pushed a signed tag and started the upload when
I've seen your quick response. Sorry, I'm already a bit tired and was
a bit concerned about the upcoming freeze. I've now aborted the upload
now, so expect related mails about that to the list.

Thanks a lot for spotting the problem and finding a fix that quickly.
I'd suggest to go ahead and upload as 0.8.3-3!

BTW, can you please mention the following bugs in debian/changelog:

#657885 #678186 (I'm confident that your patch fixes both)

and #678997 (which I forgot to include).

Thanks a lot!

Bug#657885: ffmpeg: Illegal instruction on dreamplug (arm cpu)

2012-06-25 Thread Loïc Minier

tag 657885 + pending confirmed
stop

It seems the various "make install" runs for each flavour overwrite each
other's binaries so that in the end the neon binaries like
/usr/bin/ffmpeg get installed instead of the flavour-independent
binaries.

Fix committed in git, trying to prepare an upload.

   Cheers,

I see. Your machine is not ARMv7 capable, yet, the baseline flavor of
libavcodec does seem to use ARMv7 instructions. cf.
http://blogs.arm.com/software-enablement/251-how-to-load-constants-in-assembly-for-arm-architecture/

Can you please retrieve a backtrace with libav-dbg installed? I need
to know where exactly in the code the offending instruction occurs in
order to determine if it's an upstream bug or a configuration issue.

Thanks
Reinhard

Fwd: Bug#657885: ffmpeg: Illegal instruction on dreamplug (arm cpu)

2012-06-25 Thread Reinhard Tartler

Hi Loïc,

Can you perhaps have a look at this bugreport? Either the dynamic
loader is doing something wrong here on armel, or the libavcodec
baseline shared library builds do enable armv7 instructions after all.

AFAIUI, this does not only affect the dreamplug but also the (supposly
popular) raspberry pi. Can/Shall we do something about it before the
freeze?

Cheers,
Reinhard
