libsmf: do not add a non-zero EndOfTrack event at end of all-zero tracks

27 January 20:49 - Ardour - Paul Davis

This can lead to confusion when trying to decide if the file contains an explicit duration, since we end up with a track who last event has a non-zero delta time from the previous one.

avcodec/nvenc: add b_adapt option for HEVC encoder

27 January 12:58 - FFmpeg - Diego de Souza

The b_adapt option allows users to control adaptive B-frame decision when lookahead is enabled in HEVC encoding.

[base, smooth] Implement direct LCD filtering

26 January 17:43 - FreeType - Alexei Podtelezhnikov

Applying an LCD filter to spans rather than the entire image improves the performance of ClearType-like rendering by about 40% at 32 ppem and much more at larger sizes.

dlfcn: Add dlinfo request type RTLD_DI_ORIGIN_PATH (bug #24298)

26 January 12:49 - glibc - Arjun Shankar

The existing dlinfo request type RTLD_DI_ORIGIN used for querying the value of the '$ORIGIN' dynamic string token is prone to buffer overflows. This commit adds a new request type named RTLD_DI_ORIGIN_PATH that returns a pointer to the dynamic string token (i.e.

lavc/hevc: add aarch64 neon for 8-bit dequant

25 January 06:55 - FFmpeg - Jun Zhao

Implement NEON optimization for HEVC dequant at 8-bit depth. The NEON implementation uses srshr (Signed Rounding Shift Right) which does both the add with offset and right shift in a single instruction. Optimization details:- 4x4 (16 coeffs): Single load-process-store sequence- 8x8 (64 coeffs): Fully unrolled, no loop overhead- 16x16 (256 coeffs): Pipelined load/compute/store to hide memory latency- 32x32 (1024 coeffs): Pipelined with all available NEON registers Performance benchmark on Apple M4: ./tests/checkasm/checkasm --test=hevc_dequant --bench hevc_dequant_4x4_8_c: 11.3 ( 1.00x) hevc_dequant_4x4_8_neon: 6.3 ( 1.78x) hevc_dequant_8x8_8_c: 33.9 ( 1.00x) hevc_dequant_8x8_8_neon: 6.6 ( 5.11x) hevc_dequant_16x16_8_c: 153.8 ( 1.00x) hevc_dequant_16x16_8_neon: 9.0 (17.02x) hevc_dequant_32x32_8_c: 78.1 ( 1.00x) hevc_dequant_32x32_8_neon: 31.9 ( 2.45x) Note on Performance Anomaly: The observation that hevc_dequant_32x32_8_c is faster than 16x16 (78.1 vs 153.8) is due to Clang auto-vectorizing only for sizes >= 32x32.

lavc/hevc: optimize dequant for shift=0 case (identity transform)

25 January 06:55 - FFmpeg - Jun Zhao

The HEVC dequantization uses: shift = 15 - bit_depth - log2_size When shift equals 0, the operation becomes an identity transform:- For shift > 0: output = (input + offset) >> shift- For shift < 0: output = input << (-shift)- For shift = 0: output = input << 0 = input (no change) This occurs in the following cases:- 10-bit, 32x32 block: shift = 15 - 10 - 5 = 0- 12-bit, 8x8 block: shift = 15 - 12 - 3 = 0 Previously, the code would still iterate through all coefficients and perform redundant read-modify-write operations even when shift=0. This patch adds an early return for shift=0, avoiding unnecessary memory operations.

lavc/hevc: add aarch64 neon for 10-bit dequant

25 January 06:55 - FFmpeg - Jun Zhao

Implement NEON optimization for HEVC dequant at 10-bit depth.

lavc/hevc: add aarch64 neon for 12-bit dequant

25 January 06:55 - FFmpeg - Jun Zhao

Implement NEON optimization for HEVC dequant at 12-bit depth. For 12-bit: shift = 15 - 12 - log2_size = 3 - log2_size.
