* mpeg12: Ignore slice threading if hwaccel is activeRémi Denis-Courmont2013-07-25
| | | | | | | Slice threading does not work with hardware acceleration, as decoding is per-picture. This fixes Bugzilla #542. Signed-off-by: Diego Biurrun <diego@biurrun.de>
* vdpau: Fix VC-1 interlaced modeRainer Hochecker2013-07-25
| | | | | | | | VDPAU expects the bitstream value (0, 2 or 3). libavcodec uses an enum (0, 1 or 2). Signed-off-by: Rémi Denis-Courmont <remi@remlab.net> Signed-off-by: Diego Biurrun <diego@biurrun.de>

* arm: Comment out unused labels in simple_idct_armMartin Storsjö2013-07-24
| | | | | | | | | | | | | | | | | When building for iOS in thumb mode, gas-preprocessor.pl doesn't mark unused labels as thumb functions (as it does for other local labels, where it can figure out that they are functions due to being referenced in branch instructions). This leads to linker warnings for some of those local labels, such as: ld: warning: ARM function not 4-byte aligned: __a_evaluation from libavcodec/libavcodec.a(simple_idct_arm.o) Therefore, comment them out since they don't have any function. They do still have a value in documenting key points in the assembly source though. Signed-off-by: Martin Storsjö <martin@martin.st>

* fmtconvert: Add a new method, int32_to_float_fmul_array8Ben Avison2013-07-22
| | | | | | | | | | This is similar to int32_to_float_fmul_scalar, but loads a new scalar multiplier every 8 input samples. This enables the use of much larger input arrays, which is important for pipelining on some CPUs (such as ARMv6). Signed-off-by: Martin Storsjö <martin@martin.st>

* libx264: Define X264_API_IMPORTS on MSVC/ICLDerek Buitenhuis2013-07-21
| | | | | | | | | | | | | | libx264 has a few data exports which require X264_API_IMPORTS to be defined if we link to libx264 dynamically on Windows. In a similar fashion to how we handle our compat snprintf implementation, if we define it all the time, the compiler will first try and link to __imp_x264_symbol_name, and failing that, as in the case of a static libx264, will attempt to link to the non-prefixed symbol, which has already been pulled in by other x264 functions' object files.

* rtsp: Support multicast source filters (RFC 4570)Ed Torbett2013-07-19
| | | | | | | | | | This supports inclusion of one single IP address for now, at the media level. Specifying the filter at the session level (instead of at the media level), multiple source addresses, exclusion, or using FQDNs instead of plain IP addresses is not supported (yet at least). Signed-off-by: Martin Storsjö <martin@martin.st>
* rtpproto: Check the source IP if one single source has been specifiedMartin Storsjö2013-07-19
| | | | | | | | | | | | | | If another peer is sending unicast packets to the same port that we are listening on, those packets can end up being received despite using source specific multicast. For those cases, manually check the source address of received packets against the intended source address. This only handles the case when the source list is one single IP address for now, which probably is the most common case. Based on a patch by Ed Torbett. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtpproto: Support IGMPv3 source specific multicast inclusionEd Torbett2013-07-19
| | | | | | | | | Blocking/exclusion is not supported yet. The rtp protocol parameter takes the same form as the existing sources parameter for the udp protocol. Signed-off-by: Martin Storsjö <martin@martin.st>

* avserver: Remove unused loadable module supportMartin Storsjö2013-07-18
| | | | | | | | | | There is no record of this ever being used at all, anywhere, since the feature was added in 2effd274466. This gets rid of extra linker tricks just to support a feature that isn't used, simplifying portability to other platforms. Signed-off-by: Martin Storsjö <martin@martin.st>

* mov: Do not allow updating the time scale after it has been setMartin Storsjö2013-07-15
| | | | | | | | | | | | The time scale is set in mdhd, and later validated in the enclosing trak atom once all of its children have been parsed. A loose mdhd atom outside of a trak atom could update the time scale of the last stream without any validation.

* ac3dec: Don't consume more data than the actual input packet sizeMartin Storsjö2013-07-15
| | | | | | | | | | | | | | | This was handled properly in the normal return case at the end of the function, but not in this special case. Returning a value larger than the input packet size can cause problems for certain library users. Returning the actual input buffer size unconditionally, since it is not guaranteed that frame_size is set to a sensible value at this point.
