This avoids returning duplicate timestamps for multiple packets when the demuxer does not provide all timestamps and packet duration is not known.

This modifies pts in situations other than what was intended, leading to invalid timestamps. Reverts commit 90bb394d

This prevents sample_rate/data_length from going negative, which caused various crashes and undefined behaviour further down. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org

It was to signal that allocations are 16-byte aligned, but AVX requires 32-byte alignment, thus the check is no longer useful (and causes crashes).

This properly synchronizes frame size changes between threads if subsequent threads abort decoding before frame size is initialized, i.e. it prevents the thread after that from ping-ponging back to the original value. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind

Starting with version 4.7, gcc properly supports unaligned memory accesses on ARM. Not using the inline asm with these compilers results in better code. Signed-off-by:

With a dereferenced type-cast pointer as memory operand, gcc 4.6 and later will sometimes copy the data to a temporary location, the address of which is used as the operand value, if it thinks the target address might be misaligned. Using a pointer to a packed struct type instead does the right thing. The 16-bit case is special since the ldrh instruction addressing modes are limited compared to ldr. The "Uq" constraint produces a memory reference suitable for an ldrsb instruction, which supports the same addressing modes as ldrh. However, the restrictions appear to apply only when the operand addresses a single byte. The memory reference must thus be split into two operands each targeting one byte. Finally, the "Uq" constraint is only available in ARM mode. The Thumb-2 ldrh instruction supports most addressing modes so the normal "m" constraint can be used there. Signed-off-by:

SDL only supports s16 sample format and a limited number of channel layouts. Some versions of SDL on some systems support 4-channel and 6-channel output, but it's safer overall to downmix any layout with more than 2 channels to stereo.

To load unaligned vector data in the usual way, explicit vec_ld() should be used rather than dereferencing a pointer to a vector type. When the VSX extension is enabled, gcc may compile vector pointer dereferences using the VSX lxvw4x instruction instead of the lvx instruction typically used with Altivec/VMX. As the behaviour of these instructions with unaligned addresses differs, it is important that only lvx is used here. Signed-off-by:
