[FFmpeg-devel] [PATCH 4/6] avcodec/vorbisenc: Move encoder structures and macros to separate file

Encoder structures are moved to a separate header file to improve readability. Signed-off-by: Tyler Jones --- libavcodec/vorbisenc.c | 118 +--- libavcodec/vorbisenc.h | 145 + 2 files

[FFmpeg-devel] [PATCH 2/6] avcodec/vorbisenc: Apply dynamic frame lengths

Additional codebooks are added for shorter 128-sample frames. Changes in codeword generation are made to handle valid values of 0 that prepend some codebooks, otherwise books are classified incorrectly and cause unreadable streams. A second residue, floor, and mapping is created for short window

[FFmpeg-devel] [PATCH 1/6] avcodec/vorbisenc: Add pre-echo detection

The encoder will attempt to determine the existence of transient signals by applying a 4th order highpass filter to remove dominant low frequency waveforms. Frames are then split up into blocks where the variance is calculated and compared with blocks from the previous frame. A preecho is only

The settings used for initializing the floor and residue codebooks are separated so that they aren't coupled for later changes for arbitrary channel configurations. Signed-off-by: Tyler Jones --- libavcodec/vorbis_enc_data.h | 112 ++---

[FFmpeg-devel] [PATCH 3/6] avcodec/vorbisenc: Add clipping avoidance

Clipping is avoided by taking the maximum value of each frame before window application, and scaling down the entire frame by a scalar factor. Signed-off-by: Tyler Jones --- libavcodec/vorbisenc.c | 8 libavcodec/vorbispsy.c | 17 +

[FFmpeg-devel] [PATCH 0/6] avcodec: Vorbis encoder improvements

Please see the following patches. The first two patches are identical to my latest pending changes sent to the mailing list on July 28. Changelogs are included regardless. The clipping avoidance patch should remove most clicking that had been noticed by atomnuker in previous versions. Thanks in

[FFmpeg-devel] [PATCH] all: avoid data imports across DLL boundaries

From: Pedro Pombeiro DLL data imports cause problems on Windows. They normally require each variable to be correctly marked with dllimport/dllexport declspecs. For MSVC, we define av_export to dllimport declspec. This is not entirely correct - depending on which sub-lib

Hi! Attached patch tries to slightly simplify and clean up the usage of put_bits* in libavcodec: put_bits_le() functions exist for the little-endian G.726 encoder, so the define makes less sense now. Fate passes here, please review, Carl Eugen From 6bad007ad31c8466bcddd093c1d46cb69f75681f Mon
