Other interesting software
13 avril 2011, parWe don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
We don’t know them, we didn’t try them, but you can take a peek.

ffmpeg -i input_video.mp4 -i audio_track_1.wav -i audio_track_2.wav -i

avcodec/exr : read layers
17 février 2014, par Gonzalo Garramunoavcodec/exr : read layers
EXR files have, like tiffs, multiple channels and layers. I have a
patch for exr.c that allows you to select the layer you want to process
thru a -layer flag. It is not bulletproof but works for all layers that
have 3 channels in them (normals, motion vectors, etc).
The calling convention for ffmpeg is :ffmpeg -layer Diffuse -i myexr.%d.exr test.mov
Here’s an exr image with multiple layers :

FATE/dnn : let fate/dnn tests depend on ffmpeg static libraries
7 août 2019, par Guo, YejunFATE/dnn : let fate/dnn tests depend on ffmpeg static libraries
background :
DNN (deep neural network) is a sub module of libavfilter, and FATE/dnn
is unit test for the DNN module, one unit test for one dnn layer.
The unit tests are not based on the APIs exported by libavfilter,
they just directly call into the functions within DNN submodule.There is an issue when run the following command :
build$ ../ffmpeg/configure —disable-static —enable-shared
make
make fate-dnn-layer-padAnd part of error message :
tests/dnn/dnn-layer-pad-test.o : In function `test_with_mode_symmetric' :
/work/media/ffmpeg/build/src/tests/dnn/dnn-layer-pad-test.c:73 : undefined reference to `dnn_execute_layer_pad'The root cause is that function dnn_execute_layer_pad is a LOCAL symbol
in libavfilter.so, and so the linker could not find it when build dnn-layer-pad-test.
To check it, just run : readelf -s libavfilter/libavfilter.so | grep dnnSo, add dependency in fate/dnn Makefile with ffmpeg static libraries.
This is the same method used in fate/checkasmSigned-off-by : Guo, Yejun <yejun.guo@intel.com>
