I have a whiteboard/hand sketching app written with D3.js svg path elements. These elements are grouped into scenes with their own mp3 audio.
Multiple scenes with their animated svg paths are played according to a timeline, with the audio running perfectly.
So the end result is like a whiteboard animated movie. This works well within the app. How can i record the whole animation as a mp4 file?
I would like to run this entirely on the client side. I have looked at ffmpeg but prefer not to do a desktop install for this web app.
I looked into using (...)

I have written the below code for file conversion. The conversion fails everytime. I have imported the package ffmpeg_kit_flutter. It doesnt even show why the conversion is failing.

Is it possible to check if a video file has a subtitle using bash and get a simple answer like "yes" or "no". I don't need to know any details about the subtitles.
Maybe using ffmpeg?

I'm using ffmpeg to take input from a live stream and write an mkv file. The stream runs a few hours. I want to play the mkv file while this is in progress. I find that the players basically do "seeks" by playing through the file, which is ok for very short "seeks" but not for very long ones.
When the ffmpeg ends it finalizes the mkv file, and seeks long or short work fine.
What can I do to be able to have a more usable mkv while ffmpeg is in progress? I suppose I could force ffmpeg to create a new mkv file every hour, with a name including an index. (Is there any (...)

There is a USB camera that sends H264 frames with a frequency of 30 fps in a resolution of 1920x1080, which requires throughput of about 6 mbit/s. It is necessary to reduce this to no more than 2 mbit/s. All this is done on a weak ARMv7, so the option of transcoding is extremely resource intensive, especially considering that I did not find how to do it as a GPU Mali.
Given that the basic functionality is performed on the framework ffmpeg, is it possible to reduce the frame rate, ideally to 10 fps, WITHOUT loss of quality and (...)
