| | | | | | | | The h264_vdpau decoder crashed if output colorspace was not 8-bit 420. Add a check to error out instead (current hardware does not support other colorspaces, so successful decoding is not possible). Signed-off-by: Martin Storsjö <martin@martin.st>

* configure: clean up Altivec detectionMans Rullgard2012-08-16
| | | | | | | | | | | | | | | There used to be one test for Altivec intrinsics support and a separate test to determine which of two possible syntaxes to use for vector literals. Since 2008, we only support the more common of these so the split test no longer makes sense. This combines the tests into one and also changes the hard error on failure to a warning. The test can reasonably fail if no --cpu flag is provided (or is provided with an unknown CPU) and the compiler default target does not support Altivec. Aborting in this case is probably over-reacting. Signed-off-by: Mans Rullgard <mans@mansr.com>

* rtmp: Do not send _checkbw calls as notificationsSamuel Pitoiset2012-08-14
| | | | | | | | | | | | | | | | | | | | The _checkbw calls were changed to use transactionId 0 in commit 82613564 so that servers would not return _result/_error about it. While this is the strict interpretation of the spec, there are servers that return _error about it, even if transactionId was 0. The latest version of EvoStream Media Server (the commercial version of crtmpserver) behaves properly as described, i.e. returning an _error normally but not returning anything when using transactionId 0. The latest version of crtmpserver (right now at least) doesn't behave like this though, it returns an error even if transactionId was 0. There are also other servers that return errors even if transactionId is set to 0. Therefore set a proper transaction id so that the invoke can be tracked and the error properly ignored instead.

| | | | | | | | | This function is always called with a non-negative argument, so those special cases are not needed.

* x86: swscale: fix fragile memory accessesMans Rullgard2012-08-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | To access data at multiple fixed offsets from a base address, this code uses a single "m" operand and code of the form "32%0", relying on the memory operand instantiation having no displacement, giving a final result of the form "32(%rax)". If the compiler uses a register and displacement, e.g. "64(%rax)", the end result becomes "3264(%rax)", which obviously does not work. Replacing the "m" operands with "r" operands allows safe addition of a displacement. In theory, multiple memory operands could use a shared base register with different index registers, "(%rax,%rbx)", potentially making more efficient use of registers. In the cases at hand, no such sharing is possible since the addresses involved are entirely unrelated. After this change, the code somewhat rudely accesses memory without using a corresponding memory operand, which in some cases can lead to unwanted "optimisations" of surrounding code. However, the original code also accesses memory not covered by a memory operand, so this is not adding any defect not already present. It is also hightly unlikely that any such optimisations could be performed here since the memory locations in questions are not accessed elsewhere in the same functions. This fixes crashes with suncc. Signed-off-by: Mans Rullgard <mans@mansr.com>

* x86: yadif: fix asm with sunccMans Rullgard2012-08-13
| | | | | | | | | | | | | | | | Under some circumstances, suncc will use a single register for the address of all memory operands, inserting lea instructions loading the correct address prior to each memory operand being used in the code. In the yadif code, the branch in the asm block bypasses such an lea instruction, causing an incorrect address to be used in the following load. This patch replaces the tmpX arrays with a single array and uses a register operand to hold its address. Although this prevents using offsets from the stack pointer to access these locations, the code still builds as 32-bit PIC even with old compilers. Signed-off-by: Mans Rullgard <mans@mansr.com>
* x86: cabac: allow building with sunccMans Rullgard2012-08-13
| | | | | | | | | | | | | | | | | | | | This fixes two issues preventing suncc from building this code. The undocumented 'a' operand modifier, causing gcc to omit a $ in front of immediate operands (as required in addresses), is not supported by suncc. Luckily, the also undocumented 'c' modifer has the same effect and is supported. On some asm statements with a large number of operands, suncc for no obvious reason fails to correctly substitute some of the operands. Fortunately, some of the operands in these statements are plain numbers which can be inserted directly into the code block instead of passed as operands. With these changes, the code builds correctly with both gcc and suncc. Signed-off-by: Mans Rullgard <mans@mansr.com>
* x86: mlpdsp: avoid taking address of voidMans Rullgard2012-08-13
| | | | | | | | | | | | | | This code contains a C array of addresses of labels defined in inline asm. To do this, the names must be declared as external in C. The declared type does not matter since only the address is used, and for some reason, the author of the code used the 'void' type despite taking the address of a void expression being invalid. Changing the type to char, a reasonable choice since the alignment of the code labels cannot be known or guaranteed, eliminates gcc warnings and allows building with suncc.
