    libjpeg-turbo

    libjpeg-turbo

    SIMD-accelerated libjpeg-compatible JPEG codec library

    libjpeg-turbo is a JPEG image codec that uses SIMD instructions (MMX, SSE2, NEON, AltiVec) to accelerate baseline JPEG compression and decompression on x86, x86-64, ARM, and PowerPC systems. On such systems, libjpeg-turbo is generally 2-6x as fast as libjpeg, all else being equal. On other types of systems, libjpeg-turbo can still outperform libjpeg by a significant amount, by virtue of its highly-optimized Huffman coding routines. In many cases, the performance of libjpeg-turbo rivals that of proprietary high-speed JPEG codecs. libjpeg-turbo implements both the traditional libjpeg API as well as the less powerful but more straightforward TurboJPEG API. libjpeg-turbo also features colorspace extensions that allow it to compress from/decompress to 32-bit and big-endian pixel buffers (RGBX, XBGR, etc.), as well as a full-featured Java interface.

    Randirplay

    Generates a playlist of files in directories in random directory order

    Generates a playlist of files in directories in random directory order. Preserves the alphebetical ordering within directories but lists directories in a random order. Enables you to create a music playlist of random albums if you keep albums in separate directories. lots of directory scanning configuration options and size limiting. Will also produce a playlist to fit the free space on a specified device. Good for grabbing a random selection of albums to transfer to your device or just to be able to play albums in a random order if your device doesn't have this feature. You can also use it to generate separate playlists for separate directories by running it multiple times in another script (this is my current use for it in my Android device).
