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.

How to speed up my video creating/encoding pipeline
23 septembre 2015, par user606521I am creating a video from 120 JPEG images and concatening it with intro video.
- video (and images) dimmensions : 960x540
- video/audio output format that I need : mp4 H.264, AAC
I am creating video from JPEG images using following command :
ffmpeg -f lavfi -i anullsrc -r 60 -i pipe:0 -y -acodec aac -strict experimental \
-shortest -movflags frag_keyframe+empty_moov -f mp4 video.mp4It creates 2 seconds (120 frames with 60FPS) mp4 video with "silence" (silent audio). video.mp4 size is 94KB. This process takes 1 second. (Note that I am passing images through pipe:0).
Next I concatenate it with existing intro.mp4 video (H.264, AAC, 931KB, lasts 6 seconds) using following command :
ffmpeg -i intro.mp4 -i video.mp4 -y \
-filter_complex "[0:0] [0:1] [1:0] [1:1] concat=n=2:v=1:a=1 [v] [a]" \
-map "[v]" -map "[a]" -acodec aac -strict experimental \
-movflags frag_keyframe+empty_moov -f mp4 final.mp4It creates final mp4 H.254, AAC video which lasts 2 + 6 = 8 seconds and it’s size 990KB. This process takes 3.5 seconds.
So the whole process takes 5.5 seconds on my Mac. I have to speed it up, especially concatening videos. I am not familiar with video encoding and video formats, but I thought that maybe creating first video in mp4 and then concatening it with another mp4 video is not efficient. Are there any other formats in which I could create video (and intro) that will be faster to create/concatenate so I could encode only final video as mp4 ?
For example I could create
video.<format></format>, concatenate it withintro.<format></format>and finally encode it asfinal.mp4.Use case : I have to create videos in almost real time. 5.5 secs is ok on my Mac, but I have to execute my app on a weaker machine on which this process currently takes 3 + 15 = 18 seconds.
Also maybe there are some cool flags I could pass to ffmpeg to make it faster ?
