Hi there,
we are developing a transcoder using ffmpeg based on the transcoding example
https://www.ffmpeg.org/doxygen/4.1/transcoding_8c-example.html and we are
encountering some problem with memory usage transcoding files with large
resolutions.
When transcoding 4K files, the memory usage will go up to 3.4GB but then it
will stay steady for the rest of the conversion, and clean every thing at the
end. While transcoding video files with larger resolution (8K) the app, which
is 32bit, will run out of memory (>4GB).
It does not look like a memory leak, as memory usage will grow as long as
transcoding a certain amount of frames and then it will stay steady. It looks
like the amount of memory usage depends on the resolution of the frame, but
even with a 8K frame using >4GB is not expected.
Is this a known behavior?
Is there a way to limit the number of frames loaded on memory or the amount of
memory while transcoding?
Or building a 64bit version would fix this issue?
Any help would really be appreciated.
Thank you,
Simone.
