Instead of relying on system #ifdefs which may or may not be correct, detect the POSIX ioctl signature at configure time. (cherry picked from commit 00b64fca55a3a009c9d0e391c85f4fd3291e5d12) Signed-off-by:Brad Smith <brad@comstyle.com>

Without resetting it, if there was a previous set of varstreams with subtitles, it would subtract from all the streams, leading to chaos and segfaults when trying to access for example stream -1.

binutils 2.43 has stricter validation for labels[1] and results in errors when building ffmpeg for armv5: src/libavcodec/arm/mlpdsp_armv5te.S:232: Error: junk at end of line, first unrecognized character is `0' Remove the leading zero in the "01" label to resolve this error.

The snow encoder uses block based motion estimation which can read out of array if insufficient alignment is used It may be better to only apply this for the encoder, as it would safe a few bytes of memory for the decoder. Until then, this fixes the issue in a simple way.

We currently write invalid sBIT entries for indexed PNGs, which by PNG specification[1] must be 3-bytes long. The values also are capped at 8 for indexed-color PNGs, not the palette depth. This patch fixes both of these issues previously fixed in the decoder, but not the encoder. [1]: https://www.w3.org/TR/png-3/#11sBIT Regression since: c1258608 . Signed-off-by:

The PNG specification[1] says that sBIT entries must be at most the bit depth specified in IHDR, unless the PNG is indexed-color, in which case sBIT must be between 1 and 8. We should not reject valid sBITs on PNGs with indexed color. [1]: https://www.w3.org/TR/png-3/#11sBIT Regression since 84b45493 . Signed-off-by:

Commit 4ef5e7d4 add qmin/qmax support to videotoolbox encoder. The default value of (qmin, qmax) is (2, 31), which makes bitrate control doesn't work as users' expectations. Signed-off-by:
