[FFmpeg-devel] [PATCH] for bug in libavformat/avio.c

[Thorsten Jordan]

Hello,

i encountered a SIGSEGV in libavformat/avio.c when one registers an own
protocol and lets the url_open fail.

The reason is that url_fopen() calls url_open() and after that
url_fdopen() which calls init_put_byte() to set ByteIOContext::opaque.
If url_open() fails, opaque is 0, but in url_close this is not checked
-> segfault.

Attached patch fixes this.

I hope it is ok to post this here, or should it go to roundup?
