  27 ## Future improvements
  28
  29 ### Embedded audio/video player in browsers
  30
  31 * For a given enclosure, depending on autodetected MIME:
  32     * `audio/*` -> `<audio>`
  33     * `video/*` -> `<video>`
  34 * For a given template:
  35     * `page.tmpl` -> eagerly fetch media
  36     * `inlinepage.tmpl` -> fetch just enough to display durations
  37 * Only for HTML5 sites, or also okay for XHTML?
  38 * Does this work well enough in enough browsers, or do we need a
  39   JavaScript player to fill in some gaps?
  40
  41 ### iTunes fancy podcasting
  42
  43 * [iTunes-specific tags](https://www.apple.com/itunes/podcasts/specs.html)
  44   appear to be RSS-only
  45     * Can we always include them in RSS feeds, or would that break
  46       some feed readers?
  47     * Is it even valid to include them in Atom feeds? If so, do
  48       Atom podcasts look any better in podcatchers?
  49     * Avoid adding a third kind of feed (`itunesrss`), or options
  50       to the existing `rss` and `atom` feeds, unless we have to.
  51 * Notable tags for feeds:
  52     * `itunes:subtitle`
  53     * `itunes:author`
  54     * `itunes:summary` (same as `description`)
  55     * `itunes:owner` (includes `itunes:name` and `itunes:email`)
  56     * `itunes:image href=''`
  57     * `itunes:publisher`
  58     * `itunes:category text=''` (can contain subcategories)
  59     * `itunes:keywords`
  60 * Notable tags for entries:
  61     * `itunes:duration`
  62         * [[!cpan Audio::TagLib]] might be fastest, if present and applicable
  63         * [ffprobe](http://ffmpeg.org/ffprobe.html) is reasonably fast
  64         * [mediainfo](http://mediainfo.sourceforge.net/) is way slower
  65         * Cache computed durations as pagestate
  66 * [Podcast Feed Best
  67   Practice](https://github.com/gpodder/podcast-feed-best-practice/blob/master/podcast-feed-best-practice.md)
  68   from the gPodder folks
  69
  70 ### Fancy podcast aggregating
  71
  72 * Write tests comparing a fancy podcast (HTML and feeds) against
  73   the same podcast aggregated and republished, then make them pass
  74   via changes to `aggregatepost.impl` and [[plugins/aggregate]].
  75
  76 ### Other ideas
  77
  78 * Optionally specify the enclosure's:
  79     * MIME type, in case `File::MimeInfo` guesses wrong.
  80     * Duration, in case `ffprobe` guesses wrong.
  81 * Optionally specify enclosures outside the wiki:
  82     * Some people don't want to store big unchanging files in the VCS.
  83     * Other people like [podcasting found media](http://huffduffer.com/about).
  84     * We'd have to download the file just to compute some metadata
  85       about it, and then somehow not frequently re-download it.
  86 * Configurably generate additional subscription links (such as
  87   iTunes) alongside the RSS/Atom ones in [[plugins/inline]].
  88 * Support Apple's "enhanced podcasts" (if they're still relevant).
