Mon Nov 29 21:47:49 EET 2021
New in V18
- rebased to latest head (to fix merge conflict in allfilters.c)
- textmod: Removed two trailing blanks from sf_textmod.c
- xsubdec: fix xsubdec regression found by Michael; packet size estimation
as flawed
- splitcc: Fix uninitialzed locals
- splitcc: Do not propagate hwcontext on secondary output
- testsub2video: fix output timeing, re-add mutex locking and implement
render_latest_only parameter
New in V17
- Applied almost all suggestions that were made (thanks everybody!)
- Split the initial commit, no longer moving the legacy structs (AVSubtitle..)
- Use the regular encoding API for subtitles
- Updated subtitle encoders to handle packet allocation
- Removed compatibility layer for accessing legacy encoders
- Updated the compatibility implementation for the legacy subtitle encode api
- Reordered commits and merged ffmpeg.c changes into a single commit
New in V16
- Added missing reference to subfmt.h iun libzvbi-teletextdec.c
- Fixed Fate error in patch 15/16
- Removed all trsiling whitespace in tilers.texi
New in V15
- Rebased to upstream changes
- avcodec/subtitles: Migrate subtitle encoders to frame-based API and provide
compatibility shim for legacy api
- fftools/ffmpeg: Use new frame-based subtitle encoding API
- AVSubtitleArea: copy flags field, make params const
- graphicsubs2text: Don't emit duplicate frames
- graphicsubs2text: Combined OCR output into a single AVSubtitleArea
(I have a prototype for detecting text colors and positions, but it's not
ready at this point)
- splitcc: cleanup local subtitle_header ref
- stripstyles: add parameter for ass layer selection
- avcodec/subtitles: deferred loading of ass header for text subtitle encoders
- verified all example command lines in the docs are working, added somre more
Kind regards,
