Talk:FFMPEG An Intermediate Guide/subtitle options

As somebody commented on the main page of this book, “it is a mixture of documentation lists (for formats, codecs) without any additional info (often lacking explanation) and personal opinion”; it can be a little lacking overall. The subtitle section here is better developed than most of the rest of the book, but the last part, which gives a sample command of how to search relatively deeply for a subtitle stream, is a little lacking. Shouldn't -probesize and -analyzeduration be explained in greater detail? What are they, what units do the following numbers represent, etc. Noble are the intentions behind this œuvre, but a little lacking is the execution. कामत (discuss • contribs) 11:13, 27 August 2016 (UTC)

MP4 Subtitle formats seems a bit naked. SubtitleEdit supports almost 100 formats, at least 10 that I tried of which seem not to be supported by FFMPEG in MP4 format (STL, TTXT, SRT, VTT, TTXT.XML, ASS) despite various reference to these formats. Can someone confirm and document? Thanks! I will post what I find out and am successful. Command line: ffmpeg -i a.mp4 -i a.ass -c:v copy -c:a:copy -c:s copy -map 0:0 -map 0:1 -map 1:0 out.mp4 using latest build. Hansschulze (discuss • contribs) 22:34, 6 August 2020 (UTC)
