Jeremy Morton	2700063655	Don't use tcp_fd if we're not using TCP-based connections (e.g. when reading direct SDP files to set up UDP-based RTP-streams). Fixes issue 1713.

Måns Rullgård	7f8c3d1f4d	configure: fix --cpu=nocona Use x86_64_suggest instead of _select as otherwise fast_cmov being disabled (as it should be for nocona) also disables x86_64 breaking the build. Originally committed as revision 21446 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Martin Storsjö	3debf366c8	Check for getaddrinfo in the winsock headers. This makes us link directly to getaddrinfo if it is available, making binaries incompatible with anything prior to windows XP.

Originally committed as revision 21442 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Martin Storsjö	d9cd11ad44	Only define _WIN32_WINNT=0x0501 if $target_os = "mingw32".

Carl Eugen Hoyos	b52fcba9cd	Fix decoding ATI VCR2 codec, sample in samples/V-codecs/ATI-VCR12/ATI/VCR2test.avi Software decoding was broken since r8865, when two new context variables were added, but not initialized in vcr2_init_sequence(). Another such context variable was added in r18381. Originally committed as revision 21438 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	b0634fd11e	Doxument url_open(). Originally committed as revision 21437 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Carl Eugen Hoyos	895a9be60c	Force codec_tag I420 for Quicktime Planar Y'CbCr 8-bit 4:2:0 raw codec, because YV12 triggers an UV swap in rawdec.c, fixes issue 1687. Originally committed as revision 21436 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	aa2ead8215	Fix mis-computation of the needsDither variable erroneously introduced in r30419, which was causing a swscale-example regression. Also increase my liter count by 20.0 units. Originally committed as revision 30431 to svn://svn.mplayerhq.hu/mplayer/trunk/libswscale	15 years ago
Michael Niedermayer	996b099a0f	Branchless setting of MB_TYPE_8x8DCT. Not benchmarked as i failed to find a sample that uses this one. But it should be faster. Originally committed as revision 21435 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	81afcf1fae	Remove cruft. Originally committed as revision 21434 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	d9ef0d2e14	Mark index as unsigend so gcc knows it doesnt need a sign extension on x86_64. Any tips on how i can convince gcc that it doesnt need a mov %eax, %eax in every get_bits() ? Originally committed as revision 21433 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	449d1442a6	a[b-1] -> (a-1)[b]. Helps gcc not to add seperate -1 instructions. Originally committed as revision 21432 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Reimar Döffinger	0b882b4009	Fix crash in MLP decoder due to integer overflow. Probably only DoS, init_get_bits sets buffer to NULL, thus causing a NULL-dereference directly after. Originally committed as revision 21426 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	8ba436171f	1 cpu cycle faster suffix_length calculation. Originally committed as revision 21425 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Laurent Aimar	f0f86627fe	VC-1/WMV3 DXVA2 implementation It allows VLD VC-1/WMV3 decoding using DXVA2 (GPU assisted decoding API under VISTA and Windows 7). It is implemented by using AVHWAccel API. Originally committed as revision 21424 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
