#407: Crash in ff_put_pixels16_neon (EXC_BAD_ACCESS)
-------------------------------------+--------------------------
Reporter: redeemarr | Type: defect
Status: new | Priority: normal
Component: avcodec | Version: unspecified

-------------------------------------+--------------------------
Platform: Iphone OS, Cortex-A8 CPU.
Library compiled with NEON asm and optimizations.
Sometimes (quite rarely) I'm getting crash in ff_put_pixels16_neon while
decoding h.264 frames. There's a lot of decoding errors due to device
load, network losses, etc. As I could understand, crash happens when
decoder tries to fix/consume decoding errors.
Feel free to contact me if you need something (if this information is not
detailed enough).
Callstack looks like:
{{{
ff_put_pixels16_neon
mc_dir_part
hl_motion
hl_decode_mb_simple
decode_mb
guess_mv
ff_er_frame_end
field_end
decode_frame
avcodec_decode_video2
}}}
