[FFmpeg-devel] [PATCH v2] avcodec: Add A2DP LATM audio support.

From: zhanquan cen This commit introduces three key components for Bluetooth A2DP LATM streams: 1.A2DP-specific LATM decoder (aac_latm_a2dp) New codec ID AV_CODEC_ID_AAC_LATM_A2DP Inherits LATMContext with A2DP extensions Attaches "a2dp_rechunk" bitstream filter. 2.Parser enhancement Ex

[FFmpeg-devel] [PATCH 1/1] libavfilter/volume: do fade when adjusting the volume.

From: zhanquan cen 1. add simple fade when volume. 2. do fade when adjust volume to maximal. when to adjust volume we hope that the audio sample is smooth we need to calculate the gradient step between each sample based on the total change of the gradient (i.e. dst_volume - src_volume) and the n

[FFmpeg-devel] [PATCH v2 0/3] lavfi: Add volume scaling, dynamic routing, and abufsrc filter

This series introduces three interdependent modules for real-time audio processing: 1. `volume` (PATCH 1/3): Provides sample-accurate gain control utilities with support for: - Linear and logarithmic volume scaling - Multi-format handling (s16/s32/flt/dbl, planar/non-planar) [7](@ref) -

[FFmpeg-devel] [PATCH 1/1] avfilter/abufsrc: add audio buffer source filter with dynamic routing.

From: zhanquan cen This commit introduces a new audio buffer source filter `abufsrc` designed for scenarios requiring dynamic audio routing and real-time processing control. Key features include: 1. **Multi-Output Routing**: Supports configurable mapping of input to multiple outputs via `map`
