Regression: Decoding of AVCHD H.264 Material fails

[rmk]

Any ffmpeg command line that requires decoding the video stream or invocation of ffplay fails with the assertion seen below:

Abort trap

I reproduced this with raw footage from the following cameras:
Panasonic GH1
Panasonic GH2
Canon HF-100
Sony CX-6

I attached a short sample from the GH2

I cannot reproduce this problem on ia32, intel64 (both Linux) and ppc (OS X 10.5):

[rmk]

weird. I just did a clean recompile to make sure (make distclean;configure;make clean;make) and it does happen as described and it does not happen with a clean build of ffmbc-0.7rc2. Maybe someone else running OS X could verify?

[Carl Eugen Hoyos]

Could you add some system information?
And please try --cc=clang (and/or another gcc version if available).

[Carl Eugen Hoyos]

And since this is a regression for you, please find the version introducing it.

[rmk]

After a colleague couldn't reproduce it on OS X, I did a clean git clone and it didn't happen here either. I thought git pull without errors + clean/distclean was sufficient but was obviously wrong. I apologize for time wasted and promise to always doublecheck with a clean git clone before I submit a bug report. Please close as invalid.

[Carl Eugen Hoyos]

Thank you for the clarification.
