wm4	816577716b	avcodec/dvdsubdec: fix accessing dangling pointers dvdsub_decode() can call append_to_cached_buf() 2 times, the second time with ctx->buf as argument. If the second append_to_cached_buf() reallocs ctx->buf, the argument will be a pointer to the previous, freed block. This can cause invalid reads at least with some fuzzed files - and possibly with valid files. Since packets can apparently not be larger than 64K (even if packets are combined), just use a fixed size buffer. It will be allocated as part of the DVDSubContext, and although some memory is "wasted", it's relatively minimal by modern standards and should be acceptable.

Martin Storsjö	2dbd35b00c	libfdk-aacdec: Make sure decoding doesn't add any extra delay in the latest version of fdk-aac The latest version added support for a new option for enabling a signal level limiter, which adds some extra delay. In fdk-aac, this is enabled by default, but disable it by default here since we'd rather have zero-delay decoding. Signed-off-by: Martin Storsjö <martin@martin.st>	10 years ago

Martin Storsjö	8a3d9ca603	libavcodec: Add an OpenH264 encoder wrapper Compared to existing, common opensource H264 encoders, this can be useful since it has got a different license (BSD instead of GPL). Performance- and qualitywise it is comparable to x264 in ultrafast mode. Hooking it up as an encoder in libavcodec also simplifies comparing it against other common encoders. This requires OpenH264 1.3 or newer. Since the OpenH264 API and ABI changes frequently, only releases are supported. To take advantage of the OpenH264 patent offer, the OpenH264 library must not be redistributed, but downloaded at runtime at the end-user's system.

Reimar Döffinger	035180901d	r210enc.c: Simplify and never store more than 10 bits. The r10k and avrp decoders would previously store 12 bit precision for the blue channel, which is inconsistent and probably not a desirable behaviour. Now the 2 unused extra bits are set to 0. This is possibly not ideal either as RGBA1010102 format has the same layout but stores alpha in these bits, thus explicitly setting them to 1 might be preferable.
