Generated 16 tile-part(s) for a total of 15 tile(s). Code-stream bytes (excluding any file format) = 92,979 = 0.994094 bits/pel. Layer bit-rates (possibly inexact if tiles are divided across tile-parts): 0.030033, 0.099090, 0.500142, 0.994094 Layer thresholds: 45466, 44551, 43327, 42651 Processed using the multi-threaded environment, with 8 parallel threads of execution }}} this is example from kakadu documentation {{{ -- Tile 1 (the second tile) gets two tile-parts. The first tile-part of tile 1 includes the first 2 layers (0.1 bits per sample) and has a layer progressive order (LRCP). The second tile-part contains the final two quality layers and has a resolution-progressive order (RLCP). The first tile-part of every tile appears first, followed by the extra tile-part of tile 1 (interleaved tile-parts). Interesting things happen when you truncate the code-stream to a bit-rate below 1.0 -- you should be able to guess. }}} {{{ C:\>ffmpeg -i ff5f.jp2 out.bmp ffmpeg version N-73010-gbb3703a Copyright (c) 2000-2015 the FFmpeg developers built with gcc 4.9.2 (GCC) configuration: --enable-gpl --enable-version3 --disable-w32threads --enable-av isynth --enable-bzlib --enable-fontconfig --enable-frei0r --enable-gnutls --enab le-iconv --enable-libass --enable-libbluray --enable-libbs2b --enable- libcaca -- enable-libdcadec --enable-libfreetype --enable-libgme --enable-libgsm --enable-l ibilbc --enable-libmodplug --enable-libmp3lame --enable-libopencore-amrnb --enab le-libopencore-amrwb --enable-libopenjpeg --enable-libopus --enable- librtmp --en able-libschroedinger --enable-libsoxr --enable-libspeex --enable-libtheora --ena ble-libtwolame --enable-libvidstab --enable-libvo-aacenc --enable-libvo- amrwbenc --enable-libvorbis --enable-libvpx --enable-libwavpack --enable-libwebp --enabl e-libx264 --enable-libx265 --enable-libxavs --enable-libxvid --enable-lzma --ena ble-decklink --enable-zlib libavutil 54. 27.100 / 54. 27.100 libavcodec 56. 41.100 / 56. 41.100 libavformat 56. 37.100 / 56. 37.100 libavdevice 56. 4.100 / 56. 4.100 libavfilter 5. 17.100 / 5. 17.100 libswscale 3. 1.101 / 3. 1.101 libswresample 1. 2.100 / 1. 2.100 libpostproc 53. 3.100 / 53. 3.100 [jpeg2000 @ 034b18e0] unsupported marker 0xFF5F at pos 0xEE9A [jpeg2000 @ 034b18e0] unsupported marker 0xFF5F at pos 0x1509A [jpeg2000 @ 034b18e0] End mismatch 1 [jpeg2000 @ 034b18e0] End mismatch 3 [jpeg2000 @ 034b18e0] End mismatch 1 [jpeg2000 @ 034b18e0] End mismatch 14 [jpeg2000 @ 034b18e0] End mismatch 4 [jpeg2000 @ 034b18e0] End mismatch 25 [jpeg2000 @ 034b18e0] End mismatch 19 [jpeg2000 @ 034b18e0] End mismatch 7 [jpeg2000 @ 034b18e0] End mismatch 12 [jpeg2000 @ 034b18e0] End mismatch 71 Input #0, j2k_pipe, from 'ff5f.jp2': Duration: N/A, bitrate: N/A Stream #0:0: Video: jpeg2000 (JPEG 2000 codestream restriction 0), rgb24, 99 9x749, 25 tbr, 25 tbn, 25 tbc Output #0, image2, to 'out.bmp': Metadata: encoder : Lavf56.37.100 Stream #0:0: Video: bmp, bgr24, 999x749, q=2-31, 200 kb/s, 25 fps, 25 tbn, 2 5 tbc Metadata: encoder : Lavc56.41.100 bmp Stream mapping: Stream #0:0 -> #0:0 (jpeg2000 (native) -> bmp (native)) Press [q] to stop, [?] for help [jpeg2000 @ 03cde020] unsupported marker 0xFF5F at pos 0xEE9A [jpeg2000 @ 03cde020] unsupported marker 0xFF5F at pos 0x1509A [jpeg2000 @ 03cde020] End mismatch 1 [jpeg2000 @ 03cde020] End mismatch 3 [jpeg2000 @ 03cde020] End mismatch 1 [jpeg2000 @ 03cde020] End mismatch 14 [jpeg2000 @ 03cde020] End mismatch 4 [jpeg2000 @ 03cde020] End mismatch 25 [jpeg2000 @ 03cde020] End mismatch 19 [jpeg2000 @ 03cde020] End mismatch 7 [jpeg2000 @ 03cde020] End mismatch 12 [jpeg2000 @ 03cde020] End mismatch 71 frame= 1 fps=0.0 q=0.0 Lsize=N/A time=00:00:00.04 bitrate=N/A video:2194kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: unknown }}} -- Ticket URL: <https://trac.ffmpeg.org/ticket/4657> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker _______________________________________________ FFmpeg-trac mailing list FFmpeg-trac@avcodec.org http://avcodec.org/mailman/listinfo/ffmpeg-trac
