2013-08-31xbadpcm: fix crash on invalid input fileAnssi Hannula
If the sample rate or channel count is zero on a file opened with ADPCMDll, a division by zero is performed causing XBMC to crash. Fix that by adding the necessary check.

2013-08-07[ffmpeg] - backport - mpegts: Remove one 64-bit integer modulus operation ↵Ben Avison
per packet The common case of the pointer having increased by one packet (which results in no change to the modulus) can be detected with a 64-bit subtraction, which is far cheaper than a division on many platforms.

2013-08-07[ffmpeg] - backport - mpegts: Make discard_pid() faster for single-program ↵Ben Avison
streams When a stream contains a single program, there's no point in doing a PID -> program lookup. Normally the one and only program isn't disabled, so no packets should be discarded.

2013-08-07[ffmpeg] - backport - mpegts: Remove one memcpy per packetBen Avison
This was being performed to ensure that a complete packet was held in contiguous memory, prior to parsing the packet. However, the source buffer is typically large enough that the packet was already contiguous, so it is beneficial to return the packet by reference in most cases.

2013-08-07[ffmpeg] - backport - avio: Add an internal function for reading without copyingBen Avison
As long as there is enough contiguous data in the avio buffer, just return a pointer to it instead of copying it to the caller provided buffer. Signed-off-by: Martin Storsjö <martin@martin.st>
