I've never seen this before where the audio stream is a separate url than a video stream listed in the manifest.
Is there a way I can combine an audio stream and a specific video stream to produce a new stream that has both audio and video in it?
I was doing something like this:
ffmpeg -i <manifest> -c copy test.m3u8 and I don't get any audio.
I've tried changing <manifest> to an individual video stream, but then no audio. If I change it to an AUDIO stream I get no video.
I recently had the problem of combining an audio .ts file with its accompanying video .ts file. I was able to solve it using the following method for Windows users. [see - Video resource ]
1) You will need to download the ffmpeg library that will allow Windows to combine both files together. In my case I was running Windows 8 (32 bit OS) and chose a static build:
2) I then opened notepad and wrote the following code once ffmpeg was installed:
ffmpeg -i VIDEO.ts -i AUDIO.ts -c:v copy -c:a copy OUTPUT.mp4
I saved the notepad file as "joiner.bat"
NB: this bat file must present in the same folder as your separate audio and video ts files in order to combine them!!!
3) Once the bat file is in the same folder as your audio and video ts files you can double click on the joiner.bat file to combine the audio and video ts files into a single mp4 (OUTPUT.mp4) file.
I hope this helps the more novice types among us. Yes I'm still a n00b after many years - don't worry! ;)

Update:
I have a video player in browser which plays mp4 videos though websocket. The player only supports mp4 file. When i checked normal mp4 fiels does not play in the player, a mp4 file with a "moovflags faststart " will only play on that player. For a allready stored file , this will work properly.
But In case of an livestream(RTSP), using ffmpeg will only work once the RTSP connection has terminated since the "moovflags faststart " flags will work once a connection has terminated properly.
Hope the above statements makes more sense.
Due to this behavior, am checking if there is any way to get the moovflasg at first or something
I am having RTSP live source and i need it to convert the RTSP to a mp4 file which has moov flags in the begining of the file.
I have checked with openrtsp to take a mp4 dump of the rtsp, but it only adds moov flags and other info on the footer of the mp4(onlky when openrtsp has closes the rtsp stream).
Ffmpeg has " -movflags faststart" to move the footer info to the header of the mp4 container.
Since i am having a RTSP live source, the video data will be comming back to back and there wont be any termination. The above ffmpeg command only works once the rtsp stream has terminated.
Is there any way we can make a mp4 container which contains the mp4 footer info present in the header itself so that i can use it for a live source?
EDIT #1
I have video player which plays mp4 video files , it only support playback of a recorded mp4 file which is createtd using "-movflags faststart" , normal mp4 files does not play in that.
This is the player
https://github.com/sonysuqin/WasmVideoPlayer.
Since i am tryng to stream live video to the player, its not possible to use movflags faststart.
The mp4 header can not be added to the file before it is complete. It’s not possible because of how mp4 files are structured. The header needs to know the frame type, timestamp, size, and file offset of every frame in the file. That can’t be known until the file is complete. You can not stream an mp4 while it is being created. You need to use a protocol such as HLS or DASH to accomplish this.
The thing which I am doing right now is that I am playing RTMP streaming on media server using ffmpeg command and also creating an audio file using google text to speech.
So I want to update mp3 file with silence if there is no content, so that it will keep will keep stream running.
I have tried 2 approaches:
By writing raw binary data to mp3 file but not working as it says content is not accurate.
Concatenate the audio content with the silence data and export file. In this scenario, I am able to update file but stream broken at the point while we are exporting file.
I have tried to write the audio file with binary data and also tried to concatenate audio content with silence and then export file but it break stream while we export the file.
I'm trying to convert DVD iso files to mp4 using HandbrakeCLI. I use the following line in a batch file:
D:\HandBrakeCLI.exe -i "D:\input.iso" -o "D:\output.mp4" --no-markers --width "720" --height "480" --preset "HQ 480p30 Surround" --encoder "mpeg2" --audio-lang-list "eng"
When I do this, I must then extract the audio from the file, using the following line:
D:\eac3to\eac3to.exe "D:\output.mp4" "D:\output.wavs" -down16
However, when I attempt to extract the audio, I get the error message
The format of the source file could not be detected.
Is there anything wrong with my former line of code that's causing the mp4 to get screwed up?
Minor side question: I'm also trying to get handbrake to remove subtitles and also only keep English audio, do you know what code could be used for that? I started a bit there with the --audio-lang-list "eng" but I'm now sure what to do from there.
Thanks a lot in advance!
You need to use a valid audio format. .wavs is not valid. You have to use an available audio codec to output to the below for --aencoder. The default output audio for MP4 is .aac
av_aac
copy:aac
ac3
copy:ac3
eac3
copy:eac3
copy:truehd
copy:dts
copy:dtshd
mp3
copy:mp3
vorbis
flac16
flac24
copy:flac
opus
copy
Defaults for audio
av_mp4 = av_aac
av_mkv = mp3
You need to pass none for no subtitles
-s none
And define only eng track like you were doing
--audio-lang-list eng
Check out the Handbrake CLI Documentation for the command line code:
https://handbrake.fr/docs/en/latest/cli/cli-guide.html
You can also try using a different program once you extract the audio. A program like XMediaRecode. It can also remux audio and video and convert other audio formats to wav

i want to try to experiment on jwplayer with video files which have 2 or more audio tracks. Can anyone provide me with a sample video or point to resource to download it?
Thank you in advance!
You can use MP4Box to construct such file as follows:
MP4Box -add file1.mp3 -add file2.mp3 output.mp4
You can use any format that MP4Box supports MP3, AAC, MP4, AVI, ...
I've created a simple example for GPAC's test files, available here.
Hi all,
I've a PHP application to manage audio files.
I've two input about audio files: file wav and file MP3
My application joins all files in to an unique mp3 file, and so I convert the wav file in mp3 file before to join them.
I'm using LAME.
File wav (conversion):
lame -m m -b 128 file.wav filewav.mp3
File mp3 (in mp3 - to create the mp3 file with same characteristics of wav conversion):
lame --mp3input -b 128 file.mp3 filemp3.mp3
The problem is: I can't join files if they are different format (filewav.mp3 and filemp3.mp3)!
Is it possible to join different files?
Thank you
Pasquale
This is more of a 'How do I approach this problem' type of question.
It's not too hard, you just need to add some logic to your script to first check and see if all files are of the same format. If they are not, then determine which ones need to be converted and run separate lame conversions on each file which isn't in your desired format. Like so:
lame -V2 input.wav output.mp3
Then, at the end of your code, join them all together with the same join statement you're using there.
lame --mp3input -b 128 file.mp3 filemp3.mp3
