video.js record timestamp blob is invalid after the first one [closed]
10 octobre 2022, par CodengineI am building a video messaging service. I have used video.js and videojs record to record video and audio.


I have used timeSlice option of record plugin to 2 second so every 2 second I get blobs which I cans save in server and then merge later.


Everything is fine. I can get the blob and upload ins server.


But the issue is - only the first blob is correct and othr blobs I cannot concate altogether. I have tried ffmpeg and opencv both to merge the videos in backend. Both says all but the first blob is incorrect.


Need help on this. I have been strugging with this last few days with no solution yet.

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

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".
