The following parts of the article will help you know more about FFmpeg WebM to MP3 conversion. The program uses Command-line based processing for file conversion and other tasks. Several tools and programs are available to help convert WebM to MP3, and FFmpeg is one of the popular ones. How to Convert WebM to MP3 with FFmpeg and the Alternative which I don't 100% understand, but also if I made any errors with the other parts as well.MP3 TRY IT FREE TRY IT FREE 1.
So the parts I wanted to ask about were parts 2. From the documentation "-f" is fmt force format into an hls codec file named index.m3u8. From documentation the "hls_list_size" is the maximum number of playlist entries if it's 0 there is no limit on playlist entries.ħ. Actually this option doesn't seem to work, I think it has something to do with hls_list_size being 0 but it does so at 8 second segments unfortunately.Ħ. From the documentation "hls_time" is the time in seconds for each segment in the playlist, although it will be cut on the next frame. So I've seen from the documentation "start_number" is the starting playlist start number, so the first segment it starts on.ĥ. As for "-s 640 x 360" this is the size and sets frame size so I'm guessing resolution? I'm not sure if I need this if I don't want to change this resolution would that be correct?Ĥ. However, I don't understand what "-profile:v baseline - level 3.0" means and I can't find reference to this in the ffmpeg documentation and I'm not sure if it's necessary. So it's a file which is a cut into a lot of parts which are part of a collective playlist.Īs a sidenote I want to keep the bitrate of the files as high as possible in the conversion.įfmpeg -i input.mp4 -profile:v baseline -level 3.0 -s 640x360 -start_number 0 -hls_time 3 -hls_list_size 0 -f hls index.m3u8ġ.So I understand the first bit "-i input.mp4" takes an input mp4 video called "input.mp4".Ģ. So I just wanted to understand this ffmpeg command I saw from Stack Overflow to convert an mp4 file to an hls format to make sure I'm not carrying any unnecessary bits of the command.Īs a preface, hls is pretty much a fragmented mp4 file, used for streaming video.
