#8644: Demux multi-image TIFF beyond first image -------------------------------------+------------------------------------- Reporter: adaerr | Type: | enhancement Status: new | Priority: normal Component: | Version: git- undetermined | master Keywords: tiff | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- I would like to create a video from a TIFF file containing a sequence of images of the same size. However currently ffmpeg decodes only the first image from the TIFF input. TIFF files containing multiple images are indeed possible, and used as native format by software ranging from scan software to scientific image processing software like ImageJ. It would be convenient if ffmpeg could decode/demux/process the sequence of images as a video input just as it can for a collection of image files. In other words, I would expect `ffmpeg -i all-frames.tif video-from-tif.webm` to produce the same video as that obtained by splitting the TIFF into separate files and running `ffmpeg -i single-frame-%03d.png video-from-png.webm` The observed behaviour (see full output below) is that ffmpeg only reads a single image from TIFF input, so that `video-from-tif.webm` contains only one frame, where `video-from-png.webm` contains the same number of frames as there are PNG files in the input. To reproduce, I attach[*] a sample TIFF with 20 frames: `20-frame-stack_416x160_grayscale-8bpp.tif` [*] Sorry, I failed to connect and upload the sample to the ftp server as specified in the instructions at http://www.ffmpeg.org/bugreports.html A test stack can also easily be generated by the convert tool from the ImageMagick software. The following command line for example produces a TIFF containing 30 256x256 grayscale (8bpp) images showing a gradient in varying orientation. `convert -size 256x256 gradient: -duplicate 29 -distort SRT '%[fx:360*t/n]' -depth 8 30-frame-stack_256x256_grayscale-8pp.tif` Here is the full log produced by a recent build from git sources: {{{ Log level: 48 Command line: /home/adrian/.local/bin/ffmpeg -report -i 20-frame- stack_416x160_grayscale-8bpp.tif -y out.webm ffmpeg version N-97504-g1128aa8753 Copyright (c) 2000-2020 the FFmpeg developers built with gcc 9 (Debian 9.3.0-10) configuration: --prefix=/home/adrian/.local --enable-gpl --enable- version3 --enable-nonfree --enable-shared --enable-pthreads --enable- libfreetype --enable-fontconfig --enable-libass --enable-gnutls --enable- librtmp --enable-libxcb --enable-libmp3lame --enable-libvorbis --enable- libspeex --enable-libopus --enable-libgsm --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libvo-amrwbenc --enable-libx264 --enable-libxvid --enable-libtheora --enable-libvpx --enable-libopenjpeg --enable-frei0r --enable-libmodplug --enable-libzmq --enable-ladspa --enable-libssh --enable-libzvbi --enable-libgme --enable-libwavpack --enable-libwebp --enable-libx265 --enable-opengl --enable-librubberband --enable-libxml2 libavutil 56. 43.100 / 56. 43.100 libavcodec 58. 82.100 / 58. 82.100 libavformat 58. 42.101 / 58. 42.101 libavdevice 58. 9.103 / 58. 9.103 libavfilter 7. 79.100 / 7. 79.100 libswscale 5. 6.101 / 5. 6.101 libswresample 3. 6.100 / 3. 6.100 libpostproc 55. 6.100 / 55. 6.100 Splitting the commandline.
