Actually, in my experience, while ffm
quickest test was the static packages linked on the ffmpeg
site, that produced greatly improved results. In your opinion, is
the choice of libx264 most optimal for this type of work or do you
recommend something else?
Thanks a lot for taking the time,

Right, so these packages are from a 3rd part re

And you wonder why it's slow. You're on x86-64. You at least have SSE2
instructions. Why are you not using them? You have to explicitly
disable assembly when building x264 to get "none".

We have a source that produces groups of JPEG images that are
352x240 and ~10K in size. There are pretty close to 3000 for a 10 minute
interval.
When I encode as follows:
ffmpeg -framerate 5 -i %05d-capture.jpg -codec copy output.mp4
I get a video that works as expected, its ~10 minutes long

Thank you very much.
Now I can get a V+A file.
Though the sound is still silent, the audio data itself seems to be included.
I will try tweaking some parameters.
Thanks anyway,

I'm trying to capture WebM(VP9+Opus) video on my macbook using ffmpeg.
I was able to create a video-only file.
But I have no idea how to create a vide+audio file.
Below are the device list and what I've done so far.
Does anyone have any advice?
Thanks,

It's an old mail. Not sure somebody has made the point. Hope not to make mess.
Hi Carlo,
You can try to change your MSYS/MINGW env. “$MSYSTEM" from "MINGW64" to
"MINGW32".
Since currently the configure file in ffmpeg don't support mingw other than
mingw32.
``` slice in ffmpeg/configure
exesuf()
你可以在这个github的作者的项目里提issue，ffmpeg官方版本对他这个目前应该也不会给与任何支持
