Ffmpeg and ffprobe not showing subtitles stream in m3u8 file
3 juin 2021, par DanielVip3I'm trying to get an mp4 video from a m3u8 playlist file (in simple HLS), with audio, video and subtitles.


I've managed to extract the video and audio stream because they are relatively easy : the input m3u8, according to ffprobe, contains 3 different programs, and the third program (called Program 2) is the one I need, because it contains both the highest quality video and the English highest quality audio.


So, what I really am doing is


ffmpeg -i "blahblah.m3u8" -c copy -map 0:p:2:v:0 -map 0:p:2:a:m:language:eng -map 0:s:0 "output.mp4"



Which means : select the first video stream for the third (index 2) program and the English language audio stream from the same third (index 2) program.


My problem is : I can't seem to find the two subtitles streams.
The m3u8 has two subtitles : English and Spanish, as you can see in the m3u8 itself

media-3/stream.m3u8



I thought it was easy : I added a
-map 0:s:0
to get the first subtitles, but ffmpeg told me that there's no stream named like that.

Then I ran ffprobe, which tells me there are no subtitles streams for him :


ffprobe "blahblah.m3u8" -show_streams -select_streams s



You can find here all the streams which the ffprobe command shows. There are lots of video and audio streams, but there are no subtitles streams.


Why don't ffmpeg and ffprobe find the subtitles streams ? Is it because they are split in a different m3u8 playlist file ?

ffmpeg : Set the language of an audio stream without touching other metadata
7 octobre 2020, par amirvfI have a MP4 file with an audio stream set to English. I want to change the language of audio stream to French.
I use the following command :


ffmpeg -i input.mp4 -map 0 -c: copy -metadata:s:v language=und -metadata:s:a:0 language=fre output.mp4



The language of audio stream changes to French without any issues, however, the "Title" of language is lost.


Initially the audio stream was like this :

Language : English

Title : AC3 5.1 Channels

After changing the language to French it is like this :

Language : French

Title : empty

How should I modify the command so it does not touch the other attributes such as "Title" ?


Thanks

FFMPEG Compilation and Video Thumbnail Issues [on hold]
2 janvier 2016, par P. PaulI have compiled FFMPEg on a Linux, Centos machine according to the guide in here https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu , and the auto video thumbnail creation command in here https://trac.ffmpeg.org/wiki/Create%20a%20thumbnail%20image%20every%20X%20seconds%20of%20the%20video
The problems are...
1- When I use
ffmpeg
orffmpeg -version
command to check if ffmpeg has been installed I get the error message, "Command not found". But when I check for ffmpeg directory "~/ffmpeg_sources
" is found and the machine says, "is a directory".2- Also, I did a test and upload video to the site to see if the video’s thumbnail will be automatically generated, but it didn’t show any thumbnail.
Any help would be greatly appreciated.
Thanks in advance !
