Hey @deepsworld,
thanks for the great issue! Glad to know that compiling mv-extractor into a conda package works. Since I have never used pyav before, I can only make some guesses also, which you could try looking into. 1) Maybe, pyav replaces some of the libraries (.so and .a files) against which mv-extractor is compiled and which are expected to be in place and unaltered. 2) Before compiling ffmpeg, I apply a patch to some of the source files. This patch is needed for the timestamp feature provided in mv-extractor. As pyav won't have this patch included, this may cause problems.
But I guess, it has got to do with point (1) as you also suggested already.
Hi @LukasBommes,
Thank you very much for your excellent work. I was able to compile this into a conda package here: https://anaconda.org/necla-ml/mv-extractor which can be installed with
conda install -c necla-ml mv-extractor
.However, when ever I use
mvextractor
alongsidepyav (conda install av -c conda-forge)
. The extractor gets stuck at this line: https://github.com/LukasBommes/mv-extractor/blob/master/src/mvextractor/video_cap.cpp#L199. Can you please let me know if you have any idea about why this could be happening. I am guessing this is caused becausepyav
also creates a wrapper around the FFMPEG library which could be conflicting with the mvextractor somehow. Here is a small script to reproduce the bug:
