delay in lyrics shown when concat video with lyrics with an intro video using ffmpeg
19 mars 2018, par no nameI have a video with lyrics I add the lyrics used ffmpeg too. I have the lyrics in lrc formate and i change it to ass lyrics formate then I start to add it to my video using this command
ffmpeg -i video.mp4 -vf "ass=out.ass,fade=in:0:30" -y amr.mp4I use fade=in:0:30 to make fade in the start of the video so when I start merge intro video my original video not start at once but to have some fade in, in the start to have a good view.
then I start to add the intro video using a text file which has thisfile intro.mp4
file amr.mp4then I merge them using this command
ffmpeg -f concat -safe 0 -i out.txt -c copy -y final.mp4i got these message
[mov,mp4,m4a,3gp,3g2,mj2 @ 03eadb80] Auto-inserting h264_mp4toannexb bitstream filter
[mp4 @ 06419580] Non-monotonous DTS in output stream 0:1; previous: 310272, current: 285626; changing to 310273. This may result in incorrect timestamps in the output file.repeated many times.
when i watch the final video the lyrics have some delay from the sound the problem appeared when I merge the intro video but without it the lyrics have no problem so what I made wrong make the lyrics shown in this way and not in the right timing as it should have no problems as I merge only the intro video and after add the lyrics to the original one
Thanks in advance -
FFMPEG and JNI - pass AVFrame data to Java and Back
17 octobre 2015, par tishuI have some C code that decodes a video frame by frame. I get to a point where i have an AVFrame in BGR32 and would like to send it back to Java for editing.
I have a ByteBuffer object in my C code that was created in Java using AllocateDirect but i struggle to write the content of the AVFrame->data[0] (of uint8_t type) to it and read it back. I have tried memcpy with no luck. Does anyone have an idea how to achieve this ?
UPDATE
Followed Will’s comment below and wrote this in Cchar *buf = (*pEnv)->GetDirectBufferAddress(pEnv, byteBuffer);
memcpy(buf, rgb_frame->data[0], output_width*output_height*4);The buffer does contain some data in Java but doing the following returns a null bitmap
BufferedImage frame = ImageIO.read(bitmapStream);Where bitmapStream is a ByteBufferInputStream defined here :
https://code.google.com/p/kryo/source/browse/trunk/src/com/esotericsoftware/kryo/io/ByteBufferInputStream.java?r=205Not sure if I am not writing things correctly in this buffer
UPDATE 2
Got pretty close now thanks to the latest snippet. I am using BGR32 format in my C code ie 4 bytes per pixel. So I modified things a bit in Java :
final byte[] dataArray = new byte[width*height*4];
imageData.get(dataArray);
final BufferedImage image = new BufferedImage(width, height, BufferedImage.TYPE_INT_BGR);
final DataBuffer buffer = new DataBufferByte(dataArray, dataArray.length);
Raster raster = Raster.createRaster(sampleModel, buffer, null);
image.setData(raster);I get the image correctly but there seems to be an issue with color channels
Tried different formats with no luck

How to sync network audio with a different network video and play it with chewie
26 mars 2023, par Rudra SharmaI am trying to stream a reddit videos on my app. For that reason I am using Reddit API but it is only giving the video url like 'redd.it/mpym0z9q8opa1/DASH_1080.mp4 ?source=fallback' with no audio but after some research I found out that we can get audio url by editing video url 'redd.it/mpym0z9q8opa1/DASH_audio.mp4 ?source=fallback'.


Now I have both audio and video url with me how can I sync them on network and stream them on my app using chewie package (video player).


This my code so far


import 'dart:async';
import 'dart:convert';
import 'package:http/http.dart' as http;
import 'package:flutter/material.dart';
import 'package:video_player/video_player.dart';
import 'package:chewie/chewie.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
 @override
 Widget build(BuildContext context) {
 return MaterialApp(
 title: 'Reddit Videos',
 theme: ThemeData(
 primarySwatch: Colors.blue,
 visualDensity: VisualDensity.adaptivePlatformDensity,
 ),
 home: VideoPlayerScreen(),
 );
 }
}

class VideoPlayerScreen extends StatefulWidget {
 @override
 _VideoPlayerScreenState createState() => _VideoPlayerScreenState();
}

class _VideoPlayerScreenState extends State<videoplayerscreen> {
 final List<string> _videoUrls = [];

 @override
 void initState() {
 super.initState();
 _loadVideos();
 }

 Future<void> _loadVideos() async {
 try {
 final videoUrls =
 await RedditApi.getVideoUrlsFromSubreddit('aww');

 setState(() {
 _videoUrls.addAll(videoUrls);
 });
 } catch (e) {
 print(e);
 }
 }

 @override
 Widget build(BuildContext context) {
 return Scaffold(
 appBar: AppBar(
 title: Text('Reddit Videos'),
 ),
 body: SafeArea(
 child: _videoUrls.isNotEmpty
 ? _buildVideosList()
 : Center(child: CircularProgressIndicator()),
 ),
 );
 }

 Widget _buildVideosList() {
 return ListView.builder(
 itemCount: _videoUrls.length,
 itemBuilder: (context, index) {
 return Padding(
 padding: const EdgeInsets.all(8.0),
 child: Chewie(
 controller: ChewieController(
 videoPlayerController: VideoPlayerController.network(
 _videoUrls[index],
 ),
 aspectRatio: 9 / 16,
 autoPlay: true,
 looping: true,
 autoInitialize: true,
 ),
 ),
 );
 },
 );
 }
}

class RedditApi {
 static const String BASE_URL = 'https://www.reddit.com';
 static const String CLIENT_ID = 'id';
 static const String CLIENT_SECRET = 'secret';

 static Future> getVideoUrlsFromSubreddit(
 String subredditName) async {
 final response = await http.get(
 Uri.parse('$BASE_URL/r/$subredditName/top.json?limit=10'),
 headers: {'Authorization': 'Client-ID $CLIENT_ID'});

 if (response.statusCode == 200) {
 final jsonData = jsonDecode(response.body);
 final postsData = jsonData['data']['children'];

 final videoUrls = <string>[];

 for (var postData in postsData) {
 if (postData['data']['is_video']) {
 videoUrls.add(postData['data']['media']['reddit_video']
 ['fallback_url']);
 }
 }

 return videoUrls;
 } else {
 throw Exception("Failed to load videos from subreddit");
 }
 }
}
</string></void></string></videoplayerscreen>

I think the code is self explainatory about what I am trying to achieve (Trying to make a client for reddit).
