FFmpeg

[mhsmith]

This is required by number of packages which load video and audio. Chaquopy doesn't currently provide an ffmpeg build, but there are builds available from other projects.

In particular, some users have had good results with mobile-ffmpeg (now superseded by FFmpegKit), either calling it from Java/Kotlin code, or from Python using the Chaquopy Python API. Here are some examples:

• RuntimeError: No ffmpeg exe could be found. #435 (comment)
• YTDLAndroidDownloader

Kivy's pythonforandroid also has a recipe.

@mhsmith is there any update on the integration of ffmpeg into Chaquopy? This is a very important features that should be covered in Chaquopy

[mhsmith]

Sorry, still no update. Which package do you need it for?

[mhsmith]

Some packages expect to be able to call ffmpeg as an executable, in which case #605 would be an issue. I guess mobile-ffmpeg and FFmpegKit probably deal with this by calling it as a library.

Hi, it would be great if we could use FFMPEG with chaquopy to push rtmp streams. Android is kinda of restricted with USB cameras and there is like 1 or 2 working libraries that work with USB cameras. Currently, after a long time trying I was able to retrieve frames from my camera but I need to use sockets to stream my images, would be great if it was possible to use it with ffmpeg

any update on this issue?

No, but the package build tool is now open-source, so if you'd like to try building this package yourself, follow the instructions here. And if you're successful, please make a pull request so we can add it to the public repository.

As mentioned above, anything that requires calling ffmpeg as an executable will be much more difficult on API level 29 or later. So it's probably only worth trying to build it if you intend to use it as a library.
