I now have exactly the same problem!
evercry, have you figured it out? I'll appreciate it if you share your solution.
I googled, but found no answer.

wobbals · 2011-11-15T18:18:05Z

Edwin- have you tried disabling asm support when configuring ffmpeg? This was sufficient to solve the issue for me, and the ffmpeg libraries still work fine without it.

shengbinmeng · 2011-11-16T02:41:57Z

Thank you, wobbles, disabling asm does work fine. But I should mention that I want to use NEON optimization of ffmpeg, so if disable-asm, the neon support is not possible.

ghost · 2011-11-17T15:44:36Z

Hi Edwin, any luck with this issue ?

I have also the same problem with Lion and iOS 5.0.

Looking for fix ....

shengbinmeng · 2011-11-18T01:22:35Z

Well, just for a quick work, I did this:

find the error source, that is "av_clipl_int32_arm" in libavutil/arm/intmath.h;
avoid it. (I simply comment out "#define av_clipl_int32 av_clipl_int32_arm", so don't use NEON for just that one function)

Hope to know a more professional fix :-)

ghost · 2011-11-18T01:33:56Z

Hi Edwin,

Thanks for the fix. That error gone away but unfortunately, I got another error,

libavformat/asfcrypt.o
error: invalid operand in inline asm: 'ldr ${0:Q}, $1
ldr ${0:R}, $2

What is the ffmpeg version you are using ?

Thanks

shengbinmeng · 2011-11-18T01:49:28Z

I am using kind of old version - 0.6.1, and have disabled a lot of encoders/decoders (in my application).

Anyway, what I did is only "扬汤止沸", we may all need a better fix.

ghost · 2011-11-18T02:03:59Z

Yes, we may need a proper fix.

If you don't mind, can I have the ffmpeg configure command options that you are using at terminal ?

I also don't want a lot of encoders and decoders.

Thanks,

shengbinmeng · 2011-11-18T02:17:07Z

Thanks A lot :)

ghost · 2011-11-19T06:11:49Z

Hi Edwin,

Have you built librtmp with ffmpeg and arm ?

I am having trouble with building ffmpeg with librtmp :(

I am always getting "librtmp" not found. I set the PKG_PATH to point librtmp.c but no luck.

any Idea ?

Thanks

shengbinmeng · 2011-11-19T11:48:51Z

No, I know little about using librtmp.
I googled and it seems some one has the similar problem with you. you can go do more searching.

Good luck!

lu-zero · 2011-12-15T04:00:57Z

a workaround landed libav already http://git.libav.org/?p=libav.git;a=commit;h=f7de52354fe15ba7cae141b44ffdd01e560f0e47

ciphor · 2011-12-22T09:05:40Z

I met this problem too.

davidcairns · 2012-02-17T00:59:30Z

So… any update on a fix for this?

ciphor · 2012-02-17T02:01:07Z

This error is due to that current version of gnu assembler does not support
64bit instructions.
My suggestion is to replace those 64bit assembly functions to 32bit.

zebeurton · 2012-03-05T11:35:03Z

I had also this issue. How can we replace 64 bit assembly functions to 32bit ones?

IronSight87 · 2012-04-24T13:37:59Z

Is there meanwhile a solution for that problem?

wobbals · 2012-04-24T17:46:33Z

Yes; turn the optimizations off for your target architecture. ffmpeg runs just fine without them.

IronSight87 · 2012-04-25T07:50:45Z

But this will slow down the performance. Other solutions?

zebeurton · 2012-04-25T13:31:19Z

I confirm it slown down performances. Impossible to decode correctly a 1080p video encoded in H264 on a iPad 2... It runs at two or three frame by seconds.

Any solution?

wobbals · 2012-04-25T18:36:58Z

If you feel you must have optimizations turned on, simply disable the defines for all 64-bit inline assembly declarations, as per the instructions I linked early in the thread. Here's a diff to get you started:

IronSight87 · 2012-06-03T08:39:17Z

Does anybody found a better fix?
Disable the defines, will also disable neon optimizations!
I tried configure with llvm-gcc, but ended with the same result.

mansr · 2012-08-08T00:26:01Z

This has been fixed in Libav.

Works like a charm.

It seems that another issue happens after applying libav fix :S I'm using this configuration

I can only make it using --disable-asm flag, do you have any guess what could happen with this error?

Use the following gas-preprocessor and it will work:

Woooo! It works!
