Mux video and subtitles (.mkv) Subtitles are typically embedded in mkv files, but are usually kept as separate files with mp4. Ffmpeg -i 'video.mp4' -i 'subtitle.srt' -c copy 'output.mkv' Supported subtitle formats by ffmpeg for.mkv: srt, ass, ssa and PGS (Bluray image based subtitles). Simple python script to encode videos using ffmpeg - encode.py. # extract ass subtitles and and subtitle into command: subprocess. Call (FFMPEGPATH.

Thanks for the script. Can it be modified to look for a keyword string in the first part of the file name? I want to decode only files that have 'x265' in the name (e.g. 'The.Invisible.Man.x265.DD5.1.mkv'). I assume the modification would center around this line in the script: I looked on the web and couldn't find much, and trial and error resulted in only errors. Any help you can offer would be appreciated! |

for future reference, this would be filter(lambda f: 'x265' in f and f.split('.')[-1] 'mkv', os.listdir(cwd)) |
