That's the wrong config.log. Please show us ffmpeg's config.log. As it

Dear expert,
Currently I am trying to use ffmpeg and Nvidia GPU card to decoding

Hello everyone.
I'm looking for some example (or description) with playing video stream
which is hardware decoded, but I don't want to copy data from AVFrame to
texture.
I want to reuse decoded data in GPU as texture and render it with opengl.
Is it possibly?

To lower bitrate, increase tempo and equalize at 96db, I do:
ffmpeg.exe -v 0 -i infile.mp3 -aq 10 -af atempo=1.4 -vn outfile.mp3
mp3gain /q /r /d 7 /c outfile.mp3
Can this be done with just ffmpeg?
Thanks

Hey Gyan,
I've ensured the SAR ratios and resolutions match up. The results are
still pretty funky, however. The first video last far longer than it's
supposed to and the second video is running in slow motion. Is there
nothing else that should match up?
Here are the specs on the two input vide

It depends on what you have downloaded. If that is a tarball you will have to
compile it using homebrew or something of the sort for Mac OS. If that is
binaries you just make them executable and run in terminal.

I see on this wiki for the concat filter:

Does anyone have a specific list of these attributes to ensure the concat
