screenshot: make screenshot filenames configurable This adds the --screenshot-template option, which specifies a template for the filename used for a screenshot. The '%' character is parsed as format specifier. These format specifiers insert metadata into the filename. For example, '%f' is replaced with the filename of the currently played file. The following format specifiers are available: %n Insert sequence number (padded with 4 zeros), e.g. "0002". %0Nn Like %n, but pad to N zeros (N = 0 to 9). %n behaves like %04n. %#n Like %n, but reset the sequence counter on every screenshot. (Useful if other parts in the template make the resulting filename already mostly unique.) %#0Nn Use %0Nn and %#n at the same time. %f Insert filename of the currently played video. %F Like %f, but with stripped file extension ("." and rest). %p Insert current playback time, in HH:MM:SS format. %P Like %p, but adds milliseconds: HH:MM:SS.mmmm %tX Insert the current local date/time, using the date format X. X is a single letter and is passed to strftime() as "%X". E.g. "%td" inserts the number of the current day. %{prop} Insert the value of the slave property 'prop'. E.g. %{filename} is the same as %f. If the property doesn't exist or is not available, nothing is inserted, unless a fallback is specified as in %{prop:fallback text}. %% Insert the character '%'. The strings inserted by format specifiers will be checked for characters not allowed in filenames (including '/' and '\'), and replaced with the placeholder '_'. (This doesn't happen for text that was passed with the --screenshot-template option, and allows specifying a screenshot target directory by prefixing the template with a relative or absolute path.)

X is a single letter and is passed to strftime() as "%X". E.g. "%td" inserts the number of the current day. %{prop} Insert the value of the slave property 'prop'. E.g. %{filename} is the same as %f.

commands: change property expansion format string This affects property format strings like they are used in the "show_text" input command, for --playing-msg, and other places. To quote the documentation comment on m_properties_expand_string(): ${NAME} is expanded to the value of property NAME. If NAME starts with '=', use the raw value of the property. ${NAME:STR} expands to the property, or STR if the property is not available. ${?NAME:STR} expands to STR if the property is available. ${!NAME:STR} expands to STR if the property is not available. STR is recursively expanded using the same rules. "$$" can be used to escape "$", and "$}" to escape "}". "$>" disables parsing of "$" for the rest of the string. Most importantly, "?(property:str)" becomes "${?property:str}". Make the simple fallback case easier, e.g. "${property:fallback}" instead of "${property}?(!property:fallback)". Add the ability to escape the format meta characters. "$" is used for escaping, because escaping with "\" is taken by the commands parser in the layer below. "$>" can be used to disable interpretation of format strings (of course escapes by the commands parser can't be canceled). By default, properties which are unavailable or don't exist are turned into a string signaling the status (e.g. "(unavailable)"), instead of an empty string. If an empty string is desired, this has to be done explicitly: "${property:}" (the fallback part is an empty string). Raw properties still return an empty string on error. m_properties_expand_string() now returns a talloc'ed pointer, instead of a malloc'ed one.

video: move display and timing to a separate thread The VO is run inside its own thread. It also does most of video timing. The playloop hands the image data and a realtime timestamp to the VO, and the VO does the rest. In particular, this allows the playloop to do other things, instead of blocking for video redraw. But if anything accesses the VO during video timing, it will block. This also fixes vo_sdl.c event handling; but that is only a side-effect, since reimplementing the broken way would require more effort. Also drop --softsleep. In theory, this option helps if the kernel's sleeping mechanism is too inaccurate for video timing. In practice, I haven't ever encountered a situation where it helps, and it just burns CPU cycles. On the other hand it's probably actively harmful, because it prevents the libavcodec decoder threads from doing real work. Side note: Originally, I intended that multiple frames can be queued to the VO. But this is not done, due to problems with OSD and other certain features. OSD in particular is simply designed in a way that it can be neither timed nor copied, so you do have to render it into the video frame before you can draw the next frame. (Subtitles have no such restriction. sd_lavc was even updated to fix this.) It seems the right solution to queuing multiple VO frames is rendering on VO-backed framebuffers, like vo_vdpau.c does. This requires VO driver support, and is out of scope of this commit. As consequence, the VO has a queue size of 1. The existing video queue is just needed to compute frame duration, and will be moved out in the next commit.

screenshot: make screenshot filenames configurable This adds the --screenshot-template option, which specifies a template for the filename used for a screenshot. The '%' character is parsed as format specifier. These format specifiers insert metadata into the filename. For example, '%f' is replaced with the filename of the currently played file. The following format specifiers are available: %n Insert sequence number (padded with 4 zeros), e.g. "0002". %0Nn Like %n, but pad to N zeros (N = 0 to 9). %n behaves like %04n. %#n Like %n, but reset the sequence counter on every screenshot. (Useful if other parts in the template make the resulting filename already mostly unique.) %#0Nn Use %0Nn and %#n at the same time. %f Insert filename of the currently played video. %F Like %f, but with stripped file extension ("." and rest). %p Insert current playback time, in HH:MM:SS format. %P Like %p, but adds milliseconds: HH:MM:SS.mmmm %tX Insert the current local date/time, using the date format X. X is a single letter and is passed to strftime() as "%X". E.g. "%td" inserts the number of the current day. %{prop} Insert the value of the slave property 'prop'. E.g. %{filename} is the same as %f. If the property doesn't exist or is not available, nothing is inserted, unless a fallback is specified as in %{prop:fallback text}. %% Insert the character '%'. The strings inserted by format specifiers will be checked for characters not allowed in filenames (including '/' and '\'), and replaced with the placeholder '_'. (This doesn't happen for text that was passed with the --screenshot-template option, and allows specifying a screenshot target directory by prefixing the template with a relative or absolute path.)
