Download ffdshow tryouts beta 6

If you want to play a video or sound file on a bare Windows machine, you will soon run into the problem that a format is not recognized and is therefore not playable or poorly playable. To solve this problem, the correct codecs will have to be installed for each format. You can also install ffdshow, a Directshow and vfw codec that uses libavcodec, Xvid, and other open source libraries. Unfortunately, the development of ffdshow has come to a standstill for a while. However, a group of users of the Doom9 forum has resumed development. This has created a branch, which they themselves call the ‘ffdshow tryouts’. A few days ago the group released beta 6 and the changelog of it looks like this:

Bug fixes

• Important security fix: Buffer overflow vulnerability was fixed
• Fixes to ffdshow’s remote API
• GDI resource leak fix
• subtitle fixes:
  • Fixed missing character at the end of line with non-UTF8 encoding in embedded subtitles
  • When activating SSA tags within SRT subs, default placement (with no tag) was not correct
  • Subtitle stability fix for random crashes
• Workaround for crashes in applications that use the Windows Media Player SDK
• Wrong color fix for Fraps v5
• The Grab filter was producing a black right border when saving PNG images having a width which was not a multiple of 16
• OSD / Info & CPU: Show correct value in “Movie FPS”
• Crash due to a language file size limit was fixed

New and improved features

• Added support for E-AC3 decoding (Dolby Digital Plus)
• Added support for DTS-HD decoding (core DTS only)
• Added support for Dolby TrueHD and MLP decoding (full TrueHD decoding or AC3 can pass-through depending on config)
• New deinterlacer: yadif (Yet Another DeInterlacing Filter)
• Updated libavcodec with the latest code from the FFmpeg project
• Volume normalization:
  • One pass normalization added. This mode is used to reach the highest possible loudness with minimum of possible artifacts
  • Improved normalization, the probability of clipping has been decreased
• Added support for S/PDIF sample rates other than 48kHz: Pass-through of 44.1kHz AC3/DTS streams plays back correctly now
• Dynamic range compression level for AC3 and E-AC3 sources can now be set between 0 and 100%
• AC3/DTS pass-through settings are now based on presets
• DVD playback support by libavcodec
• Tweaked compatibility list reporting: Executable names that are not yet in the default whitelist/blacklist are now reported only
• Unicode support for FFDShowRemoteAPI
• Language file size limit was increased, all language files are now encoded as UTF-16LE+BOM
• Various OSD updates:
  • Buffer limit increased from 256 to 2048 characters
  • HTML encoding support similar to SRT files
  • Added SSA support for OSD and combobox to select the format (HTML/SSA)
• SRT files with tags support: SSA tags support in SRT files and HTML tags support in SSA files
• Improved compatibility with certain MPEG2 Transport / Program Stream demultiplexers (eg DVBSource, Elecard) for files that contain H.264 video
• Support H.264 digital television playback in DVBViewer
• Improved H.264 seeking
• Added an option to deinterlace only frames flagged as “interlaced”
• Enhanced interlacing options allow to choose the method (auto, weave, bob) as well as the field order (auto, top field, bottom field)
• Color space conversion: Added option “Force progressive” and “Force interlace”
• Flag telecined frames as progressive (libmpeg2)
• H.264: Correct field order, interlace/progressive flags are decoded
