ffmpeg conversion failed error while splitting a 1.57GB .tif file
12 janvier 2023, par MinaiI am running ffmpeg to split a large .tif image of dimensions 25966 * 64114 into grids 0f 256 * 256 pixels but am getting an error.


I ran the ffmpeg command on an 1883 * 1361 pixel .jpg image named coral2




Using the following command :


ffmpeg -i coral2.jpg -qscale:v 1 -vf "crop=256:256:0:256" coral2-0-256.jpg




When I run the same command on a 1.57GB .tif image :


image.tif -qscale:v 1 -vf "crop=256:256:0:256" image%01d.tif


I get the following error :

Please help. My code only works on splitting crops of small images but I cannot crop large .tif images. How can I split using ffmpeg ?

configure : don't disable '-ftree-vectorize' on GCC >= 13 on major architectures
14 juillet, par Jiaweiconfigure : don't disable '-ftree-vectorize' on GCC >= 13 on major architectures
This changes configure to stop disabling -ftree-vectorize on
GCC versions 13 and newer, on major architectures.Background :
Original `-fno-tree-vectorize` was added in 2009 in commit
973859f5230e to avoid compiler errors.Re-enabled in 2016 in commit cb8646af24bd but caused failures due
to inline CABAC assembly issues and was disabled again in
fd6dbc53855fb.Commit 182663a58a7a in 2023 fixed the inline CABAC assembly issues.
Recent versions of GCC, in particular 13 and newer, seem to
generally work reliably with respect to vectorization, although bugs
have been observed on Loongarch.Cautiously allow the GCC default of having vectorization enabled,
on major architectures where we expect to see enough testing. If
further issues are observed, they should be reported and noted here in
configure, so the workarounds can be scoped and version limited.
