Hi everyone ! I would like to create a new topic with a list of your FFMPEG scripts that you are using for converting your video files and get them working correctly on different client devices. Feel free to share your scripts šŸ˜ƒ ---

Here is a script I devlopped with a friend of mine. Im using it to remux my avi and mp4 files to mkv container. this is not for converting video and audio. Language used: Python Before running this script on your librairie please test it before with 2 or 3 files. This script will delete the sources files one by one once remuxing is done. How to use: 1. Create a Python file with the code provided bellow. 2. Call the script and add the directory path of your videos. Per example: script.py d:\ ---

Hereā€™s my script to remux mkv files to mp4 if the video is h264, otherwise it will transcode using ffmpeg. Converts audio to AAC. This is meant to get files playable in most devices. The formats can be changed so you could use it for almost any container. Also has options to extract subtitles in certain languages. I compiled my own version of ffmpeg with libfdk\_aac, which canā€™t be distributed, but you can find versions with lib\_faac. Coded in Python. Run with the files or directories to convert as arguments. It will search recursively and look for files that end in video format extensions. Change Extension to .py Before running set the remover variable to False to ensure your files arenā€™t deleted. Example Usage: python.exe mp4ffmpeg.py File1.mkv D:/Video/Movies File2.avi ---

Iā€™m new to all this ffmpeg stuff. But it happens that I download videos with audio\_ts and video splitted up. Is there a script or way, I can convert all these into a single .mkv file, for use by Plex? ---

@igowas It should work if you set the audio codec to copy. If you want to transcode the audio, then it will need the audio tracks to be mapped, I think. Currently if it transcodes, it will only get the first audio track. You can add -map 0 as a parameter to get all of the streams. Check here on how to use map: [http://ffmpeg.org/ffmpeg.html#Advanced-options](http://ffmpeg.org/ffmpeg.html#Advanced-options) ---

I tried with a powerfull server and the CPU usage was really too high. ( Chrome cast, roku and Web are not really good for x265 ) ---

It is supported in any version of ffmpeg from the last 2-3~ weeks. Explanation ripped from NVENC\_VideoEncoder\_API\_ProgGuide.pdf, as itā€™s behind a registration wall on Nvidiaā€™s developer page. > 8.2 TEMPORAL ADAPTIVE QUANTIZATION (T-AQ) > This feature tries to adjust encoding QP based on temporal characteristics of the > sequence. Temporal AQ improves the quality of encoded frames by adjusting QP for > regions which are constant or have low motion across frames but have high spatial > detail, such that they become better reference for future frames. Allocating extra bits to > such regions in reference frames is better than allocating them to the residuals in > referred frames because it helps improve the overall encoded video quality.
