Hi, Thank you so much for adding rgb48le support. It will be of great use and importance to audiovisual archives.
When I transcode an rgb48le TIFF to FFV1, the resulting ffv1 file is listed as having a pixel format of gbr16le when I decode it. I can specify a pix_fmt of rgb48le, but it would be ideal if rgb48le was selected, if the ffv1 is indeed rgb48le. I've included several terminal outputs to show that even though gbrp16le is chosen to decode the ffv1 transcoded file, when the ffv1 file is transcoded to a rgb48le TIFF, the framemd5s match the original TIFF. I'm attaching the following terminal outputs and the source file is here: https://www.dropbox.com/s/ji08myxt0ke4hy1/16bitrgb48le.tiff?dl=0 1. 16 bit (12 bits plus padding) rgb48le TIFF converted to ffv1 level 3 plus framemd5 - ed19dd966d5ed2e5c6de438949a81eaf 2. framemd5 of ffv1.mkv without specififying rgb48le - 596d6723629140e8ac7b8f818b275f89 3. transcode from ffv1.mkv to tiff (rgb48le auto selected) 4. framemd5 of 'restored' tiff (rgb48le) - ed19dd966d5ed2e5c6de438949a81eaf 1. 16 bit (12 bits plus padding) rgb48le TIFF converted to ffv1 level 3 plus framemd5 - ed19dd966d5ed2e5c6de438949a81eaf ifi-mac-pro:ifiscripts admin$ ffmpeg -i /Volumes/Stardom/kieran_tests/16bitrgb48le.tiff -c:v ffv1 -level 3 -strict -2 /Volumes/Stardom/kieran_tests/ffv1.mkv -f framemd5 - ffmpeg version N-43982-g16ea0bc Copyright (c) 2000-2016 the FFmpeg developers built with Apple LLVM version 7.3.0 (clang-703.0.31) configuration: --prefix=/usr/local/Cellar/ffmpeg/HEAD --enable-shared --enable-pthreads --enable-gpl --enable-version3 --enable-hardcoded-tables --enable-avresample --cc=clang --host-cflags= --host-ldflags= --enable-opencl --enable-libx264 --enable-libmp3lame --enable-libxvid --enable-libfreetype --enable-ffplay --disable-lzma --enable-libopenjpeg --disable-decoder=jpeg2000 --extra-cflags=-I/usr/local/Cellar/openjpeg/1.5.2_1/include/openjpeg-1.5 --enable-vda libavutil 55. 28.100 / 55. 28.100 libavcodec 57. 51.100 / 57. 53.100 libavformat 57. 46.100 / 57. 46.101 libavdevice 57. 0.102 / 57. 0.102 libavfilter 6. 50.100 / 6. 52.100 libavresample 3. 0. 0 / 3. 0. 0 libswscale 4. 1.100 / 4. 1.100 libswresample 2. 1.100 / 2. 1.100 libpostproc 54. 0.100 / 54. 0.100 [tiff_pipe @ 0x7fad84010600] Stream #0: not enough frames to estimate rate; consider increasing probesize Input #0, tiff_pipe, from '/Volumes/Stardom/kieran_tests/16bitrgb48le.tiff': Duration: N/A, bitrate: N/A Stream #0:0: Video: tiff, rgb48le, 2350x1800, 25 tbr, 25 tbn, 25 tbc File '/Volumes/Stardom/kieran_tests/ffv1.mkv' already exists.
