Sean McGovern	8835c554ff	matroskadec: introduce resync function. This allows handling matroska files with errors. Fixes test4.mkv and test7.mkv from the official Matroska test suite, and by extension Bugzilla #62.

Martin Storsjö	3965d404cc	configure: Don't add -fPIC on windows targets This avoids warnings about this option not having any effect on this platform. We still want to enable the pic configure item for these platforms (if detected via the compiler builtin define __PIC__) to get proper inline assembly workarounds. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	3fd0d166aa	configure: Don't explicitly disable PIC for windows targets This reverts `e08c946c6` and `05165c2f7a`. The actual intention of `e08c946c6` was to fix shared library builds for arm/win32, which can also be accomplished in other ways. Disabling pic on those platforms broke inline assembly on cygwin/64 (since some inline assembly requires knowing whether we are building as PIC or not), and might also break inline assembly on other compilers on windows. As a side-effect, this unfortunately brings back all the warnings about PIC not having any effect on that platform. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	2aa3325454	configure: arm: Don't try to enable pic for shared libraries on win32 The object file format doesn't support PIC loads in ARM assembly, there are no relocation types in PE/COFF that correspond to BFD_RELOC_32_PCREL (R_ARM_REL32 in ELF).

Andrey Semashev	7c020e1ad3	movenc: Grow the frag_info array in chunks Previously it was grown one element at a time, which leads to excessive reallocations. Bug-Id: 525 Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Andrey Semashev	ab1189766a	movenc: Increase the cluster array allocation by doubling The previous allocation increment of 16384 meant that the cluster array was allocated for 0.6 MB initially, which is a bit excessive for cases with fragmentation where only a fraction of that ever actually is used. Therefore, start off at a much smaller value, and increase by doubling (to avoid reallocating too often when writing long non-fragmented mp4 files). Bug-Id: 525 Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Andrey Semashev	3b4feac1ec	movenc: Keep track of the allocated size for the cluster array When writing fragmented mp4, the cluster array is reset when a fragment is written. Instead of starting off reallocating the array only based on the number of current elements in it, keep track of how many elements there were allocated earlier. This avoids reallocating this array needlessly when writing fragmented mp4 files. Bug-Id: 525 Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	fc962d4e7a	mem: Add av_realloc_array and av_reallocp_array These help avoiding overflows and simplify error handling. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago

Kostya Shishkov	31980b6abd	vmd: decode videos with no LZ buffer size provided - they might not need it The buffer is used for an additional pass of frame compression, so videos can be coded without ever using it (and some are coded so indeed, e.g. in Woodruff and the Schnibble of Azimuth game).	12 years ago
