Encoding from network takes ages compared with FFmpeg-mobile library about ffmpeg-kit

[tanersener]

This issue is fixed on ffmpeg. Updated the development branch with the latest commit from ffmpeg master. So, we will have the fix on the next release.

Thanks for reporting this. I see the same issue as well but I'm not sure about the reason. I need to run some tests to understand what is happening there.

My tests show that this commit, 70d8077b795766e2486e6ec8110f22a97362d6d6, on ffmpeg master is responsible of this performance decrease. And it affects all architectures, not only Android. iOS, tvOS and macOS also have the same problem while downloading large files over https.

Ideally, this issue must be reported to ffmpeg and fixed there. But, I couldn't reproduce it on the desktop version of ffmpeg. So, I patched the files updated on that commit for now. If it is not fixed before the next release I'll use that patch to fix this issue.

Cool, thanks a lot.

Created this ticket on ffmpeg for this issue, https://trac.ffmpeg.org/ticket/9148.

ffmpeg devs area already on it. Could you leave the file there a bit longer so they can work on the fix?

[buntupana]

Sure, no problem.

Fixed in v4.5 release.
