| # {{{ # CHANGELOG |
| # Last release changes: |
| # (The full changelog can be found at <http://p.outlyer.net/vcs/files/CHANGELOG>). |
| # |
| # 1.11.2: |
| # * Added Cook and Sipro (RealAudio 4, 5 & 6) codecs |
| # * BUGFIXES: |
| # - Remove extra, empty, temporary dir |
| # - Use standard awk syntax for exponentiation (pyth_th) |
| # - Workaround for systems that don't register fonts with ImageMagick |
| # * DEBUG: Print to stderr when probbing with mplayer too |
| # 1.11.1: |
| # * Added FLV1 codec |
| # * BUGFIXES: |
| # - Deprecate DEFAULT_INTERVAL, DEFAULT_NUMCAPS and DEFAULT_COLS as |
| # overrides, warn about their new names (interval, numcaps and cols) |
| # - Fix ImageMagick version detection |
| # 1.11: |
| # * FEATURES |
| # - Allow setting output filename. With extension will set output format, |
| # without will inherit it. |
| # - Allow percentages in height. |
| # - Require mplayer OR ffmpeg instead of both. Having both is still |
| # recommended for better results. |
| # - Safe mode, for files whose length doesn't get reported correctly. |
| # Completely automated. |
| # Number of tries can be increased with -Ws. Repeat to increase further. |
| # Use -WS to do try as many times as possible. |
| # Accuracy (stepping) can be increased with -Wp. Repeat to increase |
| # accuracy. Decrease with -WP. |
| # Can be deliberately disabled with -Wb to force processing of broken |
| # files. *VCS WITH -Wb WILL FAIL ON BROKEN FILES* |
| # - Added -dp (--disable padding) equivalent to overriding HPAD to 0 |
| # * BUGFIXES: |
| # - Don't pass ms to mplayer. It ignores them anyway and in some rare |
| # cases breaks the last capture (possibly due to the 5-frames hack) |
| # - Honor detected aspect ratio if found |
| # - Try to detect files that might fail on the last capture and trigger |
| # safe mode |
| # - Timestamps font was being ignored. As a side effect this produced |
| # italiced timestamps in some systems |
| # - Fixed obscure bug with safe_rename_pattern overrides |
| # * COMPAT: Support for bash 2.05b. This will (probably) be the last version |
| # capable of running under bash 2. |
| # * DVD mode revamp |
| # - Print title file size instead of disc size when possible |
| # - Aspect ratio detection, if available |
| # - Use of FFmpeg if available to get better information |
| # - Mostly x-platform, only ISOs identification is a bit better in Linux |
| # * Added FourCCs: 3IV1, 3IV2 (3ivx); s263 (H.263); mp4v, MP4V, H264 |
| # (MPEG-4 and AVC in mov/mp4), VP6F (VP6 Flash Version), AMR |
| # Video codec renamings: |
| # - TechSmith codec name shortened to TechSmith SCC |
| # - Raw RGB renamed to Raw video |
| # * Help cleanup. The default help output is much shorter, the full text |
| # can be displayed with --fullhelp. Also print the decoder choice near |
| # the appropriate option (-M/-F) |
| # * Added --anonymous to help (never was in it) |
| # * Drop requirement on seq/jot and bc, replaced by inline awk |
| # ... New requirement: Perl (only for DVDs). |
| # * Adopt new/fixed numbering scheme |
| # <http://p.outlyer.net/dox/vcs:devel:renumbering> |
| # * Check ImageMagick version (must decide which is the real minimum |
| # required) |
| # * Non-latin fonts revamp: |
| # - -I no longer works alone (use -Ij or -Ik instead) |
| # - -Ik, -Ij and --nonlatin try to pick an appropriate font automatically |
| # - -I accepts a font name or font filename like |
| # -Ij=Kochi-Mincho-Regular or |
| # -Ij=/usr/share/fonts/truetype/kochi/kochi-mincho.ttf |
| # * Deprecated options: |
| # --shoehorn: Will be removed unless someone really needs it. |
| # --mincho: Replaced by --nonlatin |
| # * COSMETIC: |
| # - Default font switched to DejaVu Sans. |
| # Font sizes reduced to accomodate the new default. |
| # Should fall back to a sane default if it's not available |
| # - Much tighter padding |
| # - Smaller timestamps font by default |
| # - Print friendlier timestamp when a capture fails |
| # - Print program signature to console without colour |
| # - Use main font by default in timestamps |
| # - Heading background colour toned down |
| # - Added colourised output when tput is not capable (i.e. FreeBSD) |
| # - Added prefixes when colour is not available for console output |
| # - Don't print lsdvd error channel is DVD mode |
| # - Suppress mv errors (e.g. over VFS being unable to preserve) |
| # * Minimum ImageMagick version set to 6.3.5-7 |
| # * Better detection of requirements (e.g. disallow decoders without png |
| # support) |
| # * Allow overriding height, number of captures, interval, columns, and |
| # padding |
| # * UNDOCUMENTED/DEBUG: |
| # - Allow stopping the main loop before cleaning up (--undocumented hang) |
| # - Identification-only mode. Might be promoted to an actual feature |
| # (--undocumented idonly) |
| # - Allow setting ffmpeg and mplayer path (--undocumented set_ffmpeg and |
| # set_mplayer) |
| # - Allow disabling either mplayer of ffmpeg (as if they weren't |
| # installed (--undocumented disable_ffmpeg and disable_mplayer) |
| # - Added -Wc to disable console colour, repeat to disable prefixes |
| # * INTERNAL: |
| # - assert() |
| # - Cleanup: correctness checks converted to asserts, removal of old dead |
| # code |
| # - Typos |
| # |

| # * (1.12) Start replacing 'grep' with bash's '[[ =~ ]]'. Will break bash 2 compatibility for good |
| # * (1.12 or 1.13) Start replacing 'grep' with bash's '[[ =~ ]]'. Will break bash 2 compatibility |
| # for good |
| # * [[x1]] Find out why the order of ffmpeg arguments breaks some files. |

| #+ SUS v2: egrep is deprecated, grep -E replaces it |

| # --undocumented shoehorn -> NONE 1.12 1.13 or 1.14 |
| # --funky -> --profile ? ?+1 |
| # MIN_LENGTH_FOR_END_OFFSET -> none 1.11 1.12 or 1.13 |

| # - UNDFLAG_*: Undocumented flags. Used internally to keep track of undocumented modes (-Z) |
