Error Opening RTMP Stream through FFmpeg command when executed through exec package [closed]
3 octobre 2024, par AkhilI have been trying to transcode the live stream from RTMP server running on
rtmp://localhost:1936/live/testwith FFmpeg in a Go application usingos/execpackage, But seems to not work and gives the input/output error (I have attached below). The same exact ffmpeg command when I execute on terminal, works as its supposed to. Not Sure why that is, here is my code for reproducing and analyzing the mistakes.

ffmpegCmd := fmt.Sprintf("ffmpeg -nostdin -i rtmp://localhost:1936/live/%s -c:v libx264 -s %s -f %s %s/stream.mpd",
 streamKey, resolution, sp.OutputFormat, outputPath)
 log.Printf("Executing FFmpeg command: %s", ffmpegCmd)

 // Prepare the command execution with a timeout context
 ctx, cancel := context.WithTimeout(context.Background(), 60*time.Second) // Set a 60-second timeout
 defer cancel()

 cmd := exec.CommandContext(ctx, "bash", "-c", ffmpegCmd)


the ffmpeg command looks like this :

ffmpeg -nostdin -i rtmp://localhost:1936/live/test -c:v libx264 -s 1920x1080 -f dash output/test/1080p/stream.mpd

I get the following error :


Error opening input: Input/output error

Error opening input file rtmp://localhost:1936/live/test.

Error opening input files: Input/output error

Exiting normally, received signal 2.

signal: interrupt


I have already tried to break the command, and then execute it. Something like :


cmd := exec.CommandContext(ctx,
 "ffmpeg",
 "-nostdin",
 "-i", "rtmp://localhost:1936/live/"+streamKey,
 "-c:v", "libx264",
 "-s", resolution,
 "-f", sp.OutputFormat,
 outputPath+"/stream.mpd")


After running the ffmpeg command with -loglevel debug and -report :


Here is the logs and errors I get :


When I run it within the go application :


ffmpeg started on 2024-10-02 at 12:00:06

VideoJS for HLS streaming not working on iOS
13 février 2024, par AamesI have a website where I stream audio using HLS (m3u8 playlist + ts files).
I use VideoJS 8.3.0 to handle the stream in the frontend side.
The streaming works in all devices (PC, Android, Mac) except in iOS where it works intermittently and often it blocks.


Here is my videojs initialization :


player = videojs('stream-id', {
 controls: false, autoplay: true, preload: 'auto',
 html5: {
 vhs: {overrideNative: false},
 nativeAudioTracks: true
 }
 });

...

player.src({ type: 'application/x-mpegURL', src: 'https://.../master.m3u8' });



And these are the headers of the m3u8 file :


#EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:10
#EXT-X-PROGRAM-DATE-TIME:2024-02-13T09:00:00Z
#EXT-X-MEDIA-SEQUENCE:0
#EXT-X-DISCONTINUITY
#EXTINF:10.007800,
master0.ts
#EXTINF:7.214989,
master1.ts
....


I use ffmpeg to create the playlist from mp3 files :


ffmpeg -i inputFileName -c:a aac -b:a 128k -ac 2 -f hls -hls_time 10 -preset ultrafast -map 0:a -flags -global_header -hls_list_size 0 -hls_flags append_list outputFileName



Am I doing something wrong ? Any help would be appreciated
Thanks


I tried this solution : Videojs HLS m3u8 files are not playing in iOS devices and safari browser but it does not work for me

How can I publish an RTSP stream to a MediaMTX instance with TLS encryption configured ? [closed]
15 février 2024, par cmdI have an instance of (MediaMTX) running on my laptop. I have an Amcrest IP camera. I can publish the camera's RTSP stream to the server so that the stream can be accessed from the MediaMTX instance.


However, I want to encrypt the stream. On the Github page for MediaMTX, they detail how TLS encryption can be enabled for incoming and outgoing RTSP streams by generating a server.key and server.crt and editing lines in the .yml configuration file. Streams can then be published and read with RTSPS and port 8322.


I have followed these steps, and set up the following path for my IP camera in the .yml :


###############################################
# Path settings

# Settings in "paths" are applied to specific paths, and the map key
# is the name of the path.
# Any setting in "pathDefaults" can be overridden here.
# It's possible to use regular expressions by using a tilde as prefix,
# for example "~^(test1|test2)$" will match both "test1" and "test2",
# for example "~^prefix" will match all paths that start with "prefix".
paths:

 cam1:

 runOnInit: ffmpeg -i rtsp://user:password@192.168.68.142:554 -c:v copy -c:a copy -f rtsp rtsps://localhost:8322/stream/cam1


But I am getting the following output from my MediaMTX instance when it runs :

I have no errors and was able to publish the stream with the same path configuration (using rtsp ://, not rtsps ://) when using no encryption. What possible solutions can I try ?
