* AMV: disable DR1 and don't override EMU_EDGEMichael Niedermayer2011-04-291-2/+1
| | | | | | | | | | | | This works around a possibly exploitable crash. Appearently, vlc can be exploited with a malicous file. This should get reverted as soon as a proper fix is found.

* lavf: inspect more frames for fps when container time base is coarseAnssi Hannula2011-04-292-208/+216
| | | | | | | | | | | | | | | | | | As per issue2629, most 23.976fps matroska H.264 files are incorrectly detected as 24fps, as the matroska timestamps usually have only millisecond precision. Fix that by doubling the amount of timestamps inspected for frame rate for streams that have coarse time base. This also fixes 29.970 detection in matroska.

* vorbis: Replace sized int_fast integer types with plain int/unsigned.Diego Biurrun2011-04-293-125/+113
| | | | | | int/unsigned is the natural memory access type for CPUs, using sized types for temporary variables, counters and similar just increases code size and can possibly cause a slowdown.

* avio: Fix the deprecated fallback URL-prefixed open flagsMartin Storsjö2011-04-281-3/+3
| | | | | | | | | | | | | | | | While deprecated, they're totally useless as long as their values are different from the AVIO_FLAG values that are used internally. Currently, this leads to old libav applications still compiling correctly (since we haven't removed the fallback wrappers), but failing since the functions internally compare to the new AVIO_FLAG values. These should be removed at some point, but they aren't removed yet. The intent is to be able to recompile an old application against the new ABI without modifying the code, and this doesn't work currently. Signed-off-by: Martin Storsjö <martin@martin.st>

* network: Check POLLERR and POLLHUP in ff_network_wait_fdGil Pedersen2011-04-281-1/+1
| | | | | | | | Previously, the function would lead to an infinite wait (by returning AVERROR(EAGAIN)) on sockets indicating an error via either of these poll flags. Signed-off-by: Martin Storsjö <martin@martin.st>

* aacdec: remove sf_scale and sf_offset.Alex Converse2011-04-272-20/+8
| | | | | | | Instead, scalefactors are adjusted by the offset amount, removing the need for sf_scale, and the MDCT scales are adjusted to compensate for the higher scalefactors. Floating-point output will be handled by modifying the MDCT scales.

* qpeg: use reget_buffer() in decode_frame()Stefano Sabatini2011-04-271-6/+3
| | | | | | | | | | | Decoder relies on previous frame data, so use reget_buffer(). This also set frame->reference to 3, as the frame will be requested unmodified later so it shouldn't be modified by the application. Fix playback of file Clock.avi. Signed-off-by: Ronald S.

* smacker: remove unnecessary call to avctx->release_buffer in decode_frame()Stefano Sabatini2011-04-271-2/+0
| | | | | | | | | The release_buffer was cleaning the provided frame, thus causing the successive call to avctx->reget_buffer() to allocate a new frame. In case the returned frame was not the same one previously returned but a new one with different data, it resulted in artifacts. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
