osd: use libass for OSD rendering The OSD will now be rendered with libass. The old rendering code, which used freetype/fontconfig and did text layout manually, is disabled. To re-enable the old code, use the --disable-libass-osd configure switch. Some switches do nothing with the new code enabled, such as -subalign, -sub-bg-alpha, -sub-bg-color, and many more. (The reason is mostly that the code for rendering unstyled subtitles with libass doesn't make any attempts to support them. Some of them could be supported in theory.) Teletext rendering is not implemented in the new OSD rendering code. I don't have any teletext sources for testing, and since teletext is being phased out world-wide, the need for this is questionable. Note that rendering is extremely inefficient, mostly because the libass output is blended with the extremely strange mplayer OSD format. This could be improved at a later point. Remove most OSD rendering from vo_aa.c, because that was extremely hacky, can't be made work with osd_libass, and didn't work anyway in my tests. Internally, some cleanup is done. Subtitle and OSD related variable declarations were literally all over the place. Move them to sub.h and sub.c, which were hoarding most of these declarations already. Make the player core in mplayer.c free of concerns like bitmap font loading. The old OSD rendering code has been moved to osd_ft.c. The font_load.c and font_load_ft.c are only needed and compiled if the old OSD rendering code is configured.

osd: make the OSD and sub font more customizable Make more aspects of the OSD font customizable. This also affects the font used for unstyled subtitles (such as SRT), or when using the --no-ass option. This adds back some customizability that was lost with commit 74e7a1 (osd: use libass for OSD rendering). Removed options: --ass-border-color --ass-color --font --subfont --subfont-text-scale Added options: --osd-color --osd-border --osd-back-color --osd-shadow-color --osd-font --osd-font-size --osd-border-size --osd-margin-x --osd-margin-y --osd-shadow-offset --osd-spacing --sub-scale The font size is now specified in pixels as it would be rendered on a window with a height of 720 pixels. OSD and subtitles are always scaled with the window height, so specifying or expecting an absolute font size doesn't make sense. Such scaled pixel units are used to specify font border etc. as well. (Note: the font size is directly passed to libass. How the fonts are actually rasterized is outside of our control, but in theory ASS font sizes map to "script" pixels and then are scaled to screen size.) The default settings should be about the same, with slight difference due to rounding to the new scales. The OSD and subtitle fonts are not separately configurable. It has limited use and would double the number of newly added options, which would be more confusing than helpful. It could be easily added later, should the need arise. Other small details that change: - ASS_Style.Encoding is not set to -1 for subs anymore (assuming subs use VSFilter direction in -no-ass mode too) - use a different WrapStyle for OSD - ASS forced styles are not applied to OSD

osd: make the OSD and sub font more customizable Make more aspects of the OSD font customizable. This also affects the font used for unstyled subtitles (such as SRT), or when using the --no-ass option. This adds back some customizability that was lost with commit 74e7a1 (osd: use libass for OSD rendering). Removed options: --ass-border-color --ass-color --font --subfont --subfont-text-scale Added options: --osd-color --osd-border --osd-back-color --osd-shadow-color --osd-font --osd-font-size --osd-border-size --osd-margin-x --osd-margin-y --osd-shadow-offset --osd-spacing --sub-scale The font size is now specified in pixels as it would be rendered on a window with a height of 720 pixels. OSD and subtitles are always scaled with the window height, so specifying or expecting an absolute font size doesn't make sense. Such scaled pixel units are used to specify font border etc. as well. (Note: the font size is directly passed to libass. How the fonts are actually rasterized is outside of our control, but in theory ASS font sizes map to "script" pixels and then are scaled to screen size.) The default settings should be about the same, with slight difference due to rounding to the new scales. The OSD and subtitle fonts are not separately configurable. It has limited use and would double the number of newly added options, which would be more confusing than helpful. It could be easily added later, should the need arise. Other small details that change: - ASS_Style.Encoding is not set to -1 for subs anymore (assuming subs use VSFilter direction in -no-ass mode too) - use a different WrapStyle for OSD - ASS forced styles are not applied to OSD

osd: use libass for OSD rendering The OSD will now be rendered with libass. The old rendering code, which used freetype/fontconfig and did text layout manually, is disabled. To re-enable the old code, use the --disable-libass-osd configure switch. Some switches do nothing with the new code enabled, such as -subalign, -sub-bg-alpha, -sub-bg-color, and many more. (The reason is mostly that the code for rendering unstyled subtitles with libass doesn't make any attempts to support them. Some of them could be supported in theory.) Teletext rendering is not implemented in the new OSD rendering code. I don't have any teletext sources for testing, and since teletext is being phased out world-wide, the need for this is questionable. Note that rendering is extremely inefficient, mostly because the libass output is blended with the extremely strange mplayer OSD format. This could be improved at a later point. Remove most OSD rendering from vo_aa.c, because that was extremely hacky, can't be made work with osd_libass, and didn't work anyway in my tests. Internally, some cleanup is done. Subtitle and OSD related variable declarations were literally all over the place. Move them to sub.h and sub.c, which were hoarding most of these declarations already. Make the player core in mplayer.c free of concerns like bitmap font loading. The old OSD rendering code has been moved to osd_ft.c. The font_load.c and font_load_ft.c are only needed and compiled if the old OSD rendering code is configured.

osd: make the OSD and sub font more customizable Make more aspects of the OSD font customizable. This also affects the font used for unstyled subtitles (such as SRT), or when using the --no-ass option. This adds back some customizability that was lost with commit 74e7a1 (osd: use libass for OSD rendering). Removed options: --ass-border-color --ass-color --font --subfont --subfont-text-scale Added options: --osd-color --osd-border --osd-back-color --osd-shadow-color --osd-font --osd-font-size --osd-border-size --osd-margin-x --osd-margin-y --osd-shadow-offset --osd-spacing --sub-scale The font size is now specified in pixels as it would be rendered on a window with a height of 720 pixels. OSD and subtitles are always scaled with the window height, so specifying or expecting an absolute font size doesn't make sense. Such scaled pixel units are used to specify font border etc. as well. (Note: the font size is directly passed to libass. How the fonts are actually rasterized is outside of our control, but in theory ASS font sizes map to "script" pixels and then are scaled to screen size.) The default settings should be about the same, with slight difference due to rounding to the new scales. The OSD and subtitle fonts are not separately configurable. It has limited use and would double the number of newly added options, which would be more confusing than helpful. It could be easily added later, should the need arise. Other small details that change: - ASS_Style.Encoding is not set to -1 for subs anymore (assuming subs use VSFilter direction in -no-ass mode too) - use a different WrapStyle for OSD - ASS forced styles are not applied to OSD
