* hls: add missing checks for accessing avoption fieldsMichael Niedermayer2013-01-23
| | | | | | Fixes null pointer exception and probably other things Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

* lavf/segment: exit immediately in case of invalid stream specifierStefano Sabatini2013-01-23
| | | | | Avoid duplicated confusing error message, and propagate error code from the failing avformat_match_stream_specifier() call.
* lavf/segment: avoid failure in case -flags +live and -segment_times/frames ↵Stefano Sabatini2013-01-23
| | | | | | | are specified The conflict does not apply any longer, since the M3U8 segment target duration is re-computed every time a new segment is added to the list.
* lavf/segment: drop now pointless segment_list_close() functionStefano Sabatini2013-01-23
|
* lavf/segment: mark #EXT-X-ENDLIST in M3U8 only at the end of streamStefano Sabatini2013-01-23
| | | | | | Should fix immediate playback termination. In particular, should fix trac ticket #2172.
* rtmp: fix buffer overflows in ff_amf_tag_contents()Xi Wang2013-01-23
| | | | | | | | | | | | A negative `size' will bypass FFMIN(). In the subsequent memcpy() call, `size' will be considered as a large positive value, leading to a buffer overflow. Change the type of `size' to unsigned int to avoid buffer overflow, and simplify overflow checks accordingly.

* rtmp: fix multiple broken overflow checksXi Wang2013-01-23
| | | | | | | | | | | | Sanity checks like `data + size >= data_end || data + size < data' are broken, because `data + size < data' assumes pointer overflow, which is undefined behavior in C. Many compilers such as gcc/clang optimize such checks away. Use `size < 0 || size >= data_end - data' instead.

* rtpenc: fix overflow checking in avc_mp4_find_startcode()Xi Wang2013-01-23
| | | | | | | | | | | | The check `start + res < start' is broken since pointer overflow is undefined behavior in C. Many compilers such as gcc/clang optimize away this check. Use `res > end - start' instead. Also change `res' to unsigned int to avoid signed left-shift overflow.

| | | | | | | | | | | | | | | | | | | | The theoretical minimum for a (not totally well formed) RTCP packet is 8 bytes, so we shouldn't require 12 bytes as minimum input.
