749	Apple HTTP Live Streaming segfault	takis		"Regarding applehttp.c:
If av_probe_input_buffer() fails in applehttp_read_header(), the code jumps to fail, which invokes free_variant_list() which in turn invokes avformat_close_input(), which can cause a segmentation fault if its AVInputFormat has not yet been intialized.

av_probe_input_buffer() can fail when the playlist contains URLs which the underlying TCP code can't connect to. av_probe_input_buffer uses avio_read which invokes read_data->open_input->ffurl_open->ffurl_connect->url_open2-> ... ->tcp_open->connect.


So, if you have a playlist such the one below:
EXTM3U
#EXT-X-TARGETDURATION:60
#EXT-X-MEDIA-SEQUENCE:0
#EXTINF:60,
http://172.19.40.153/20111214/stream0q2v1/fileSequence0.ts

If 172.19.40.153 is not available, ffplay f.e. segfaults."	defect	closed	important	avformat	git-master	fixed					0	0
