* Fix FS#12981 JPEG decoding problem when entropy data starts with FFBoris Gjenero2016-04-01
| | | | | | | | | | This changes JPEG fill and invalid byte handling to be like mozjpeg, and bases entropy data start on SOS marker location. Thanks to Stefan Waldmann and Dean Tersigni for reporting. Change-Id: I3c79cc6ac8d714fdc75c12b57ba427d611c99519 Chaange-Id: Ibc7c17d38d5be63642bdaf6adfd6acc2a6cf4450

* Embedded album art support in MP3/ID3v2 tags.Thomas Martitz2011-02-09
| | | | | | | | | | | - Support is limited to non-desync jpeg in id3v2 tags. Other formats (hopefully) follow in the future. - Embedded album art takes precedence over files in album art files. - No additional buffers are used, the jpeg is read directly from the audio file.

This is to a) to cleanup firmware/common and firmware/include a bit, but also b) for Rockbox as an application which should use the host system's c library and headers, separating makes it easy to exclude our files from the build. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@25850 a1c6a512-1295-4272-9138-f99709370657

* Commit part of FS#9873 - Utilise buttons for playlistingThomas Martitz2009-07-22
| | | | | | | It adds a shortcut (combo or button) to directly go from the wps to the playlist viewer. The combos could possibly be improved on some targets, but I tried to keep a tad bit of consistency (was hardly possible). I also added a corresponding touchscreen region and adapted cabbiev2. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@22003 a1c6a512-1295-4272-9138-f99709370657

* Core JPEG decoder improvements:Andrew Mahone2009-06-19
| | | | | | | | | For >8-point vertical IDCT, transpose the coefficients while decoding them, so that the vertical IDCT can read in rows rather than columns. This improves speed a bit for this size even using the C IDCT. Remove inline ARM asm, replacing it with an external file containing pure asm IDCT functions. Add jpeg_ prefix to JPEG IDCT functions since some of them will now be visible globally. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21345 a1c6a512-1295-4272-9138-f99709370657
