That means dsputil.o file had size 2.1MB with debug info. For example in Commit:22180e7a5a39f8a77498fcbce54368ecc408df8f. After the rebase onto actual master the size of dsputil.o increased to 4.7MB, which seems really wierd to me. Maybe it can be a gcc bug/feature as it is connected with optimization (--disable-optimizations reduces the size again but the speed ...). Unfortunately I can't track the commit when this situation appeared I'm only sure that the commit mentioned above is OK. I'm using gcc 4.4.5 for arm-unknown-elf target on windows/mingw. $ arm-unknown-elf-gcc -v Using built-in specs.

#156: Full HD Material from Canon 5D treated as 1920x1088 --------------------------+-------------------------- Reporter: rmk | Type: defect Status: new | Priority: normal Component: undetermined | Version: unspecified Keywords: | Blocked By: Blocking: | Reproduced: 0 Analyzed: 0 | --------------------------+-------------------------- Full HD material from the Canon 5D is detected and treated as 1920x1088 resulting in a black padding of 8 pixels at the bottom when played or transcoded. Both Quicktime and Mediainfo report the display size as 1920x1080. Since I do not have access to that camera I cannot upload a file but material is publicly available, e.g. here: http://www.dpreview.com/reviews/canoneos5dmarkii/page19.asp Mediainfo output for the video track of a sample file: Video ID : 1 Format : AVC Format/Info : Advanced Video Codec Format profile : Baseline(a)L5.0 Format settings, CABAC : No Format settings, ReFrames : 1 frame Codec ID : avc1 Codec ID/Info : Advanced Video Coding Duration : 28s 700ms Bit rate mode : Variable Bit rate : 39.1 Mbps Width : 1 920 pixels Height : 1 080 pixels Original height : 1 088 pixels Display aspect ratio : 16:9 Frame rate mode : Constant Frame rate : 30.000 fps Color space : YUV Chroma subsampling : 4:2:0 Bit depth : 8 bits Scan type : Progressive Bits/(Pixel*Frame) : 0.629 Stream size : 134 MiB (97%) Language : English Encoded date : UTC 2009-06-18 12:26:06 Tagged date : UTC 2009-06-18 12:26:06 Color primaries : BT.709-5, BT.1361, IEC 61966-2-4, SMPTE RP177 Transfer characteristics : BT.709-5, BT.1361 Matrix coefficients : BT.601-6 525, BT.1358 525, BT.1700 NTSC, SMPTE 170M -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/156> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

#98(undetermined:new): Channel reordering in pcm files

#98: Channel reordering in pcm files --------------------------+-------------------------------------- Reporter: cehoyos | Owner: Type: enhancement | Status: new Priority: minor | Component: undetermined Version: git | Keywords: pcm channel order layout Blocked By: | Blocking: Reproduced: 0 | Analyzed: 0 --------------------------+-------------------------------------- I will attach a three channel pcm caf file. The file contains left, center and right stream, FFmpeg currently warns that the channel layout is unsupported. It is simple to set the correct channel layout (trivial patch attached), but the problem is that the file has channel order "center, left, right" (MPEG-3-0-B), so that FFmpeg maps the left channel to the right, the right channel to center and the center channel to the left channel on decoding. How can a demuxer tell the pcm decoder that the decoder has to reorder channels? {{{ ffmpeg -i MPEG30B.caf FFmpeg version git-N-29301-gab15726, Copyright (c) 2000-2011 the FFmpeg developers built on Apr 23 2011 10:48:07 with gcc 4.5.2 configuration: --cc=/usr/local/gcc-4.5.2/bin/gcc --enable-gpl --enable- libcelt libavutil 51. 0. 0 / 51. 0. 0 libavcodec 53. 1. 0 / 53. 1. 0 libavformat 53. 0. 1 / 53. 0. 1 libavdevice 53. 0. 0 / 53. 0. 0 libavfilter 2. 0. 0 / 2. 0. 0 libswscale 0. 13. 0 / 0. 13. 0 [caf @ 0x12a0ae0] Unknown channel layout.
