FFmpeg Streaming Video SpringBoot endpoint not show video duration in video players
7 avril 2024, par lxluxo23it turns out that I've been working on a personal project just out of curiosity.
the main function is to stream video by first encoding it through ffmpeg
then playback said video from any other device
call it "plex" very very primitive


although I achieve my goal which is to encode and send the video to the devices that make the request
this video is sent so to speak as a live broadcast.
I can only pause it, no forward or rewind, anyone have any idea what I am doing wrong or if I should take some other approach either in my service or controller ?


I leave fragments of my code


THE CONTROLLER


@RestController
@RequestMapping("/api")
@Log4j2
public class StreamController {

 @Autowired
 VideoStreamingService videoStreamingService;

 @Autowired
 VideoService videoService;


 @GetMapping("/stream/{videoId}")
 public ResponseEntity<streamingresponsebody> livestream(@PathVariable Long videoId,@RequestParam(required = false) String codec) {
 Video video = videoService.findVideoById(videoId);
 if (video != null) {
 Codec codecEnum = Codec.fromString(codec);
 return ResponseEntity.ok()
 .contentType(MediaType.valueOf("video/mp4"))
 .body(outputStream -> videoStreamingService.streamVideo(video.getPath(), outputStream,codecEnum));
 }
 return ResponseEntity.notFound().build();
 }
}
</streamingresponsebody>


THE SERVICE


@Service
public class VideoStreamingService {

 public void streamVideo(String videoPath, OutputStream outputStream, Codec codec) {

 FFmpeg ffmpeg = FFmpeg.atPath()
 .addArguments("-i", videoPath)
 .addArguments("-b:v", "5000k")
 .addArguments("-maxrate", "5000k")
 .addArguments("-bufsize", "10000k")
 .addArguments("-c:a", "aac")
 .addArguments("-b:a", "320k")
 .addArguments("-movflags", "frag_keyframe+empty_moov+faststart")
 .addOutput(PipeOutput.pumpTo(outputStream)
 .setFormat("mp4"))
 .addArgument("-nostdin");
 if (codec == Codec.AMD) {
 ffmpeg.addArguments("-profile:v", "high");
 }
 ffmpeg.addArguments("-c:v", codec.getFfmpegArgument());
 ffmpeg.execute();
 }
}



I have some enums to vary the encoding and use hardware acceleration or not.


and here is an example from my player
the endpoint is the following


http://localhost:8080/api/stream/2?codec=AMD

screenshot

I'm not sure if there's someone with more knowledge in either FFmpeg or Spring who could help me with this minor issue, I would greatly appreciate it. I've included the URL of the repository in case anyone would like to review it when answering my question




I tried changing the encoding format.
I tried copying the metadata from the original video.
I tried sending a custom header.
None of this has worked.


I would like to achieve what is mentioned in many sites, which is when you load a video from the network, the player shows how much of that video you have in the local "buffer".

Sync Multiple Video sources based on audio
14 octobre 2016, par linuxerI have 6 videos from 6 separate cameras that I need to sync up. They don’t all start at the same time, and so I am thinking the best route would be based on audio. Is there a way to do this with ffmpeg, or is there a library for C# that I can use ?
The result needs to be that the 6 videos are synced based on audio, and then trimmed so they are all the same length and audio matches up.
I am really hoping there are some tools to simplify this, but in my searching I haven’t seen anything.

ffmpeg integration with Codeignitor [on hold]
14 novembre 2016, par NomiI am working on a project which have the following requirements...
- It should upload a video .
- then it should verify what type of video file it is i.e flv ,mp4
etc. - it should also configure its resolution according to our needs.
- and then finally save it into a database.
I have been searching the possible solution for this and learned that ffmpeg could be a solution.But i haven’t been able to learn how to code it.
Can Somebody please guide me on how to install ffmpeg with Codeignitor from scratch OR some other library which could serve the same purpose .
