How to set custom handler_name metadata for subtitle stream using FFMPEG
10 mars 2015, par AWainbI’m currently using FFMPEG to embed subtitles into my MP4 files and I am stumped trying to figure out how to custom set the "handler_name" metadata tag on my subtitle stream so I can control the name that is displayed when selecting the subtitle within a player like MPC-HC (Media Player Classic) ?
My current command to embed the subtitle is :
ffmpeg -i "video.mp4" -sub_charenc UTF-8 -i "video.srt" -c:v copy -c:a copy -c:s mov_text -metadata:s:s:0 language=eng -metadata:s:s:0 handler_name="English" -id3v2_version 3 -write_id3v1 1 "subbed_video.mp4"Output :
C:\path\to>ffmpeg -y -i "video.mp4" -sub_charenc UTF-8 -i "video.srt" -c:v copy -c:a copy -c:s mov_text -metadata:s:s:0 language="eng" -metadata:s:s:0 handler_name="English" -id3v2_version 3 -write_id3v1 1 "subbed_video.mp4"

Now, I can work around this issue by using MP4BOX to embed the subtitles into my mp4’s using :
MP4BOX -lang eng -add "video.srt:name=English" "video.mp4" -out "subbed_video.mp4"Adding "name=English" allows me to set the subtitle stream’s "handler_name" to "English" ; which displays perfectly in FFMPEG and MPC-HC, but the problem is that I do not want my app to be dependent on an additional external tool like MP4BOX if it can be avoided ?
I would greatly appreciate any advice regarding how to properly set the "handler_name" tag on my subtitle stream using FFMPEG, or maybe a confirmation as to whether FFMPEG can even handle this tag seeing as it is not technically listed in FFMPEG’s valid metadata tag list ?
P.S. As an alternative to FFMPEG, I would be willing to use AtomicParsley to set the "handler_name" as I will already be using it to set advanced metadata on the "subbed_video.mp4" after I embed the subtitles. It does seem like it would be possible to do with AtomicParsley, but I have not been able to understand half the help information with regards to setting custom ATOM’s.
TIA !!

Combining Audio and Video file in python [duplicate]
8 juin 2020, par ysoI'm trying to understand how to us ffmpeg to combine video and audio files in python. I want to combine a .avi file and a .wav file to create a final .avi file. Is this the right approach ? I'm confused by the ffmpeg syntax.
Any help would be great.



I was looking through this for help :
https://wiki.libav.org/Snippets/avconv#Combine_audio_and_video_file



import ffmpeg
import subprocess

cmd = 'ffmpeg -i inputvideo.avi -i inputaudio.wav -c:v copy -c:a aac output_video_and audio.avi'
subprocess.call(cmd, shell=True) # "Muxing Done
print('Muxing Done')
