Claudio Freire	7ec74ae4aa	AAC encoder: tweak rate-distortion logic This patch modifies the encode frame function to retry encoding the frame when the resulting bit count is too far off target, but only adjusting lambda in small, incremental step. It also makes the logic more conservative - otherwise it will contend with bit reservoir-related variations in bit allocation, and result in artifacts when frame have to be truncated (usually at high bit rates transitioning from low complexity to high complexity).	9 years ago

wm4	9aab222239	avcodec/dvdsubdec: reject some broken packets If cmd_pos is broken, this would just keep accumulating packets in the reassembly buffer, until it fails and flushes the buffer on overflow. Since packets are usually rather small, this will take a lot of subtitle packets. The perceived effect is that subtitles are not displayed anymore after the faulty packet was passed to the decoder. I'm not terribly sure about this, but on the other hand this code is active only when fragmented packets need to be reassembled. Fixes sample file in trac issue #4872.	9 years ago
wm4	f874e2728b	avcodec/dvdsub: fix partial packet assembly Assuming the first and second packets are partial, this would append the reassembly buffer (ctx->buf) to itself with the second append_to_cached_buf() call, because buf is set to ctx->buf. I do not know a valid sample file which triggers this, and do not know if packets can be split into more than 2 sub-packets, but it triggered with a (differently) broken sample file in trac issue #4872.	9 years ago

Claudio Freire	8df9bf8e39	AAC encoder: refactor to resynchronize MIPS port This patch refactors the AAC coders to reuse code between the MIPS port and the regular, portable C code. There were two main functions that had to use hand-optimized versions of quantization code: - search_for_quantizers_twoloop - codebook_trellis_rate Those two were split into their own template header files so they can be inlined inside both the MIPS port and the generic code. In each context, they'll link to their specialized implementations, and thus be optimized by the compiler. This approach I believe is better than maintaining several copies of each function. As past experience has proven, having to keep those in sync was error prone. In this way, they will remain in sync by default. Also, an implementation of the dequantized output argument for the optimized quantize_and_encode functions is included in the patch. While the current implementation of search_for_pred still isn't using it, future iterations of main prediction probably will. It should not imply any measurable performance hit while not being used.	9 years ago
