[FFmpeg-devel] Segmentation fault in libquvi.c

[Gilles Chanteperdrix]

Hi, 

I just triend libquvi, and get a segmentation fault in the
libquvi_read_header function, because ff_copy_whitelists is called
before qc->fmtctx is allocated by avformat_open_input. I added a
call to avformat_alloc_context() before ff_copy_whitelists and the
libquvi demuxer works. 

However, I wonder how to fix this properly: the error handling
labels look backward, so that I am not sure where to free the
allocated context in case of error.

Regards.
