Compilied Ffmpeg not accepting -c:v and -c:a

Create HLS streamable audio file from mp3
15 août 2023, par isADonI am using following command to create a hls aac audio file for web streaming



ffmpeg -y -i song.mp3 -c:a aac -b:a 128k -f hls -hls_time 7 -hls_list_size 0 -hls_segment_filename file%d.m4a playlist.m3u8



This command works only with some audio files. With many mp3 files I receive following output :

This is an example audio file I am trying to convert to a aac hls stream that results the mentioned problem : https://incompetech.com/music/royalty-free/index.html?isrc=USUAN1100474


How can I convert an audio file to a web friendly hls stream with ffmpeg ?

ffmpeg x11grab to streamable format
2 juin 2021, par Jintor2 FFMPEG process


(1) generating a ffmpeg x11grab to a .mp4
(2) take the .mp4 and restream it simultaneously to multiple rtmp endpoints


ISSUE the generated file in (1) have this error "moov atom not found"


This is the command that generate (1) :


ffmpeg -re -y -f x11grab -draw_mouse 0 -framerate 30 
-video_size $RESOLUTION -i :$DISPLAY_NUM -c:a aac -c:v libx264 
-movflags +faststart -preset ultrafast -crf 28 -refs 4 -qmin 4 
-pix_fmt yuv420p -filter:v fps=30 file.mp4


in the (2) => when I try to ffmpeg -i file.mp4 output somewhere : I get "moov atom not found" so the (2) can't read or open (1).


What I'm I missing


in (1)
-movflags +faststartdoesn't seem to fix the issue

••••••• EDIT : more details on the context ••••••


I'm using openvidu : webrtc with kurento and coturn.


The record feature creates a .mp4 on the fly as the chat is going on.


To start the recording, there is an API call i can make to my server and it automatically stops when all users leaves the chatroom OR do an other api call to stop. see composed video in this link https://docs.openvidu.io/en/2.17.0/advanced-features/recording/


openvidu have also webhooks.


My problem is not how to stop ffmpeg, but getting FFMPEG to encode while the mp4 or other is being generated "on the fly".


There is 2 options :


OPTION 1 : individual => 1 .webm per camare => this .webm ffmpeg can restream as hls or RTMP => it's working.


OPTION 2 : ** but the issue is with "Composed" video => it's using ffmpeg to x11grab the session... but it's mp4 without moov ato, so ffmpeg don't do anything with this.


see the composed.sh script here
https://github.com/OpenVidu/openvidu/blob/master/openvidu-server/docker/openvidu-recording/scripts/composed.sh


***************** EDIT 3 *************


in the .sh this is the part that is creating the mp4


ffmpeg -y -f alsa -i pulse -f x11grab -draw_mouse 0
-framerate $FRAMERATE -video_size $RESOLUTION -i :$DISPLAY_NUM
-c:a aac -c:v libx264 -preset ultrafast
-crf 28 -refs 4 -qmin 4 -pix_fmt yuv420p
-filter:v fps=$FRAMERATE "/recordings/$VIDEO_ID/$VIDEO_NAME.$VIDEO_FORMAT"


How can I modify this to have better result example VP8 or VP9 with good quality .webm so that the ffpmeg second command(2) can encode it live...


**** EDIT 4 ********


I tried this it worked for 30 seconds and suddenly stopped


<./stop ffmpeg -y -f alsa -i pulse -f
