Download: Showtime 3.5.122 g5f5fbaa PKG / Showtime GH 3.5.122 g5f5fbaa PKG / Showtime 3.5.122 g5f5fbaa SELF / GIT
Showtime PS3 Media Player v3.5.122 Changelog:
ps3: Fix DVD playback
Showtime should now be able to play back both ISO files and VIDEO_TS DVD folders.
ps3: Fix playback of 3.0 audio
ps3: Fix support for 4.0 audio channel layout
ps3: Round timestamps to ms precision before feeding them to the SPU decoder
For some unholy reason the SPU decoder seems to hang when timestamps are not rounded to ms precision. I've no idea why.
PS3: Use jemalloc instead of newlib's malloc
Using jemalloc significantly reduces memory fragmentation and thus mitigates the out of memory conditions that happens now and then when using Showtime (in particular during movie playback)
It's also much more efficient than newlib's malloc thanks to per-thread caching of allocation and per-thread memory arenas
For more information about jemalloc, see http://http://www.canonware.com/jemalloc/
Upgrade Showtime to use libav 0.8.1
This adds better support for multithreaded decoders and a lot of stability fixes.
For more details please see http://www.libav.org/releases/libav-0.8.release
Upgrade Spotify integration to use libspotify 11
Add user setting for configuring the VDPAU deinterlacer (Linux only)
