FFMPEG Incredibly Slow On Windows Server 2016
1er août 2019, par Ben GardnerI have a t2.small (2GB RAM, 1 vCPU) Amazon EC2 instance running a process using FFMPEG. It runs just fine ( 30 fps) on my computer (i7, 12GB RAM), but at around 2 fps on the server. Here’s the command :
rescale_command = f'ffmpeg -i {srcVideo} -filter_complex \"scale={owidth}:{oheight}, setsar=1:1, pad={dim[0]}:{dim[1]}:{oofx}:{oofy}\" {destVideo}'I’ve tried uninstalling and reinstalling ffmpeg/ffprobe
Edited per llogan’s request, I’ve also discovered that it’s relatively speedy towards the beginning (I’m rescaling 100 times over the course of the program) and slows down towards the end.
It utilizes 100% of the CPU even from the beginning, though.
Example command/output :
ffmpeg -i media/8-1-2019/hi/dl-107.mp4 -filter_complex "scale=607:1080, setsar=1:1, pad=1920:1080:656:0" media/8-1-2019/hi/sl-107.mp4ffmpeg version 3.2 Copyright (c) 2000-2016 the FFmpeg developers

Reddit api only giving video and not its audio
25 mars 2023, par Rudra SharmaI am using Reddit API to play videos on my app but the audio is not playing with the video.


This is my code. I am using chewie package and I have no idea if the problem is in the player or Reddit Api. Also I am new to flutter. The code plays reddit videos on my app on chewie video player.


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

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

 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 = 'my client id';
 static const String CLIENT_SECRET = 'my client 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");
 }
 }
}```

If you are suggesting for ffmpeg please give me code as well as I said I am new to flutter. 

I have checked my client id and client secret is correct as well. Also if there is any other package I can add to make the task easy.
