<<Back to software description

Changes for rev. 4507 (20130426) - rev. 4513 (20130525)

[r4513]
Fixed compilation warnings/errors when using Windows SDK 7.0 (e.g. VC10's WSDK)
[r4512]
Sync with IntelQuickSync Decoder 0.43 (rev90)
- D3D11 decode + VPP is not default will be used only when needed.
- D3D11 performance enhancement
- Codec name now specifies which HW acceleration is ued (D3D9/11)
[r4511]
Fix possible deadlock with downstream filter.
Based on patch of Mark Opaskar.
[r4510]
sync with QS decoder r88 - compilation issues when win8 SDK wasn't installed.
[r4509]
updated blacklist
[r4508]
Sync with IntelQuickSync Decoder 0.42 (rev87)
- D3D11 decode + VPP. Windows 8 only feature. May not work on switchable graphics solutions.
- Fixed some minor issues with VPP (time stamp interpolation).
- Fixed AVC1 frame constructor. No longer will it process AnnexB streams. This should fix TV streaming. It doesn't support fragmented streams (NALs that span more than 1 packet).
- Made legal license identical across my files.

Added option to select a preferred output colorspace
Added Intel QuickSync decoder. This provides hardware acceleration decoding of H.264, VC-1 and MPEG-2. Requires the integrated GPU of Intel Sandy Bridge processors.

Various additions to the application blacklist and whitelist
Added support for Blu-ray PGS subtitles
Removed support for USF subtitles
Various improvements for the handling of ASS/SSA subtitles. More tags are supported now, but not yet all of them.
Various improvements for the rendering of text-based subtitles
By default now only subtitle files are shown that match the video filename. This behavior can be adjusted through an option on the "Try, dialog & Paths" page in ffdshow settings.
Created new format option in ffdshow audio decoder for the QT PCM variants (such as TWOS). They were previously part if the Uncompressed audio option.
ffmpeg-mt has been merged into libavcodec
Multi-threaded decoding is now used by default for H.264, MPEG-1/2, FFV1, and DV video.
Added decoding support for Indeo 4 and Indeo 5 video
Floating point output for libavcodec AAC, AC3, E-AC3, DTS, Vorbis, and Nellymoser decoders.
Added option to disable jitter correction for audio decoder
Improved performance of Deband filter
Removed some encoders for which the interface that ffdshow provided was outdated and unmaintained, such as Xvid and H.264. You should use the official codecs instead.
Removed some encoders that were considered obsolete or unstable.
Updates
Updated Boost library to v1.49
Updated zlib library to v1.2.6
Updated minilzo library to v2.06

Changes for Beta 6 - rev. 3154 (20091209) Beta 7

Bugfixes
Various H.264 and MPEG-2 seeking issues fixed

If the center channel existed, left and right channels were ignored
Several MLP/TrueHD/LPCM decoding fixes
Playing a CSS-protected DVD using MPC or MPC-HC caused a crash in certain scenarios

General code cleanup
SSA/ASS subtitles: better compatibility (support for position & move tags), better calculation of line wrapping, new dialog to configure ASS specific options. Also support added for ASS tags within SRT subtitles (SubViewer)
