FFmpegStreamFixer is a Python script designed to manipulate MKV video files, focusing on:
-
mapping audio and subtitle streams based on user-defined priorities (language and codec type)
-
optionally adding subrip subtitles
-
converting audio codecs and optionally add them
-
organizing completed files
It can do all of that in one run.
You need to have ffmpeg-python installed.
-
Audio and Subtitle Prioritization: Prioritize and map/order audio and subtitle streams based on language and codec preferences.
-
Rename those streams to Language and Codec type, for example "ENG ac3"
-
Subtitle Addition: Option to add external subrip files (SRT) to MKV videos.
-
Audio Codec Conversion: Convert audio streams to specified codecs and bitrates. Discard the old one or keep them
-
File Organization: Option to move completed MKV files to a new directory and rename them.
-
Will delete FORCED subtitles (maybe I will make it as an option later). This is especially useful for Anime.
-
Will always default the first stream. (why? some TVs dont care about default tags, they will choose the first stream as default)
-
Will delete all audio and subtitle streams that are not in your priority lists
-
if the metadata (title, language) isnt set properly, you probably installed ffmpeg-python via pip. You can fix it by manipulating the ffmpeg-python code. Please look here: kkroening/ffmpeg-python#450
-
curretly doesnt work well, when you have have multiple audio streams with the same codec and the same language.
-
Fell free to copy the code an change it for your purpose.
