JavaFX media issue on Ubuntu : Could not create player
14 mai, par parsa2820I am trying to play mp3 file on JavaFX-11.0.2 on Ubuntu-20.04 using JDK-13.0.2 but I keep getting this same error every time. While I was searching for that I found that JavaFX uses older version of some libraries(See this issue on github). So I compiled and installed ffmpeg-3.1.11 from source. But the same exception is thrown. I put my code and error message bellow. I stuck on this for days so I really appreciate any help. Thanks.


note : This is not duplicate qeustion. All other questions regarding to this error happend on different versions and had different causes. I tried most of them but none of them works for me.

Exception running application view.GUI

This is my code. I know path and other things are correct because I can run it on Windows properly.


package view;

import javafx.scene.media.Media;
import javafx.scene.media.MediaPlayer;
import javafx.stage.Stage;

import java.io.File;

public class GUI extends javafx.application.Application{
 public void start(Stage stage) throws Exception {
 String path = "/home/parsa/Music/Ninoush.mp3";
 Media media = new Media(new File(path).toURI().toString());
 MediaPlayer mediaPlayer = new MediaPlayer(media);
 mediaPlayer.setAutoPlay(true);
 stage.setTitle("Playing audio");
 stage.show();
 }

 public static void main(String[] args) {
 launch(args);
 }
}


This is my ffmpeg and libraries versions :


ffmpeg version 3.1.11 Copyright (c) 2000-2017 the FFmpeg developers

Edit 3 : I can play wav file this way but I can't play mp3.

Node Media Server not stream when i try to pass the argument "transpose=1" to ffmpeg
28 mai 2020, par joao.jlf4I'm using node-media-server to stream to instagram, and i need to rotate the original vídeo, to be portrait. I know that there is a flag on ffmpeg called transpose (there is rotate too), but when i pass it on node_relay_session.js on 24 line at the argv array, it returns me a "[Relay end]" on console, and it does'nt stream. When I remove the transpose flag from argv array it backs to stream normaly. Here is my config to nms :



import NodeMediaServer from 'node-media-server';
import removeBarOfRtmpUrl from './utils/removeBarRtmpUrl';
import path from 'path';
import { remote } from 'electron';

export default function(data) {

const streams = data.map(stream => ({
endpoint: removeBarOfRtmpUrl(stream.endpoint),
key: stream.key,
}))

const config = {
rtmp: {
port: 1935,
chunk_size: 60000,
gop_cache: true,
ping: 30,
ping_timeout: 60
},
http: {
port: 8000,
allow_origin: '*'
},
relay: {
// C:\Users\Usuario\Desktop\multistream\node_modules.bin\ffmpeg.exe
ffmpeg: path.join(remote.app.getPath('appData'), '..', 'Local', 'Programs', 'multistream', 'app', 'ffmpeg', 'bin', 'ffmpeg.exe'),
tasks: streams.map(stream => ({
app: 'live',
mode: 'push',
edge: ${stream.endpoint}/${stream.key},

 }))
},
};

const nms = new NodeMediaServer(config);
return nms;
}

// {
// app: 'live',
// mode: 'push',
// edge: 'rtmp://a.rtmp.youtube.com/live2/keyyoutube',
// },```

Matching a specific media format with ffmpeg/avconv
5 mai 2020, par Markus A.I need to encode a video from static images in such a way that it format-matches another one so I can splice the video streams together.



Here is the
mediainfoof the file I'm trying to match :


Video
Format : AVC
Format/Info : Advanced Video Codec
Format profile : Baseline@L3.1
Format settings, CABAC : No
Format settings, ReFrames : 1 frame
Codec ID : 7
Duration : 2mn 46s
Bit rate : 1 614 Kbps
Width : 1 280 pixels
Height : 720 pixels
Display aspect ratio : 16:9
Frame rate mode : Variable
Standard : NTSC
Color space : YUV
Chroma subsampling : 4:2:0
Bit depth : 8 bits
Scan type : Progressive
Stream size : 32.0 MiB (87%)
Color primaries : BT.601 PAL
Transfer characteristics : BT.601
Matrix coefficients : BT.601



So far, what I have been able to come up with is the following :



avconv -f image2 -framerate 1.2 -i loop_%d.tif -c:v libx264 -preset veryslow -profile:v baseline -level:v 31 -b:v 1614K -refs 1 loop.flv



This gets me to :



Video
Format : AVC
Format/Info : Advanced Video Codec
Format profile : Baseline@L3.1
Format settings, CABAC : No
Format settings, ReFrames : 1 frame
Codec ID : 7
Duration : 2s 917ms

Frame rate mode : Constant
Frame rate : 1.200 fps
Color space : YUV
Chroma subsampling : 4:2:0
Bit depth : 8 bits
Scan type : Progressive

Which, unfortunately, still isn't good enough as VLC Media Player crashes hard (just closes), logging
main error: Failed to compensate for the format changes, removing all filters; main error: Failed to create video converteras soon as the stream splice occurs. I tried splicing another stream in that does have the exact same encoding, and it works fine. I'm also making sure to only splice on key-frames and I am including the NALU containing the AVCDecoderConfigRecord, so I'm pretty sure I'm not doing anything else wrong, especially since a couple other programs are fine with the splice. It's just VLC that expects an even closer match.


Here are things I've tried :



- 

- Adding
-vsync 2to get variable frame rate mode. Doesn't change anything. - Adding
-color_primaries bt470bg -color_trc gamma28 -colorspace bt470bgto try to get BT.601 PAL settings (several websites mentioned this). Doesn't change anything. - Adding
-s ntscto set the standard to NTSC. This also changes the resolution to 720x480 (not OK), and specifying-s 1280x720in addition gets rid of the NTSC tag again.









If anyone knows what flags I need to supply to get closer, that would be super-helpful ! The stream I'm trying to match is encoded on an Android device (it's a live-stream), so I'm assuming it is built using the standard Android MediaCoder framework, in case that helps.
