It is one of the backends for many of the GUI tools mentioned in other answers. The following table provides a mapping from audio sample format to the corresponding FFmpeg decoder name.
Changing container without re-enconding content could not be simpler: ffmpeg -i input. You can exclude the "-c copy" when extracting the subtitles and FFMPEG fill run it through its subrip codec and produce nearly identical results.
This way the operation finishes almost immediately. It contains a sequential number of subtitles, start and end timestamps, and subtitle text. VLC and other players have no problem to detect the subtitle encoding automatically without manual help. I want to keep stereo audio and h video the same, which I can do. Fast, accurate, and affordable. My suggestion: Use the VLC player! It can visualise the Teletext right in the video area. Among variety of features, FFmpeg can capture video and audio from your computer's camera and stream them over network to someNote: ffmpeg may not come with SRT support in older distributions of Linux, so check the repository sources to ensure that ffmpeg comes with libsrt support, as there is no easy way of getting OBSIn this simple post, I want to share with you about my previous side-project - how I broadcasted radio to Youtube using DigitalOcean and FFmpeg.
You can do the same thing. It is used for streaming, transcoding and editing of video etc. Convert returns a generator that needs to be iterated to drive the conversion process.
