ffmpeg - Adding and Removing Subtitles without Changing the Video
28 septembre 2018, par MeCeI’m trying to embed subtitles into video and removing the subtitles back again without changing the video, meaning I want the output video to be the same with the original video.
I’m using the following command to embed the subtitles
ffmpeg -i original.mp4 -i original.srt \
-c:v copy -c:a copy -c:s mov_text \
-map_metadata 0:g -map_metadata:s:v 0:s:v -map_metadata:s:a 0:s:a \
-movflags +faststart -threads 8 \
output.mp4To remove the subtitles,
ffmpeg -i output.mp4 \
-c:v copy -c:a copy \
-map_metadata 0:g -map_metadata:s:v 0:s:v -map_metadata:s:a 0:s:a \
-movflags +faststart -threads 8 \
-sn \
removed.mp4The output is almost the same but I couldn’t figure out what would cause the difference. When I compare the binaries, almost all of the differences are
original: 0xF3
removed: 0xF4The bytes are incremented by 1, I think only in the header.
Can you help ? Thank you in advance.

Why does HTML5 video with very large h.264 encoded mp4 (with +faststart, ie metadata at beginning), take ages to load ?
15 septembre 2015, par Tom JenkinsonThe video is rendered with ffmpeg with the "faststart" flag added meaning the metadata should be at the start of the file, and the server appears to be handling partial content requests correctly, so why does it need to have downloaded so much of the video before the player becomes enabled and can play the video ? I am testing it in Google Chrome.
Once the player becomes enabled I can seek around to various points in the video pretty instantly and see the new partial content requests being made.
Here is a link to the video :
http://iptv.la1tv.co.uk/unibrass.mp4Here is a jsbin with the video tag : https://jsbin.com/rahewidoru . It takes a few minutes but does work after it loads.
Any suggestions ?
I realise there are other methods like HLS and dash which use chunks, but I would like to know why it isn’t working this way because I can’t find anywhere that provides a reason as to why it doesn’t work well.
