ffmpeg Audiosegment error in get audio chunks in socketIo server in python
26 janvier 2024, par a_crszkvc30Last_NameColI want to send each audio chunk every minute.
this is the test code and i want to save audiofile and audio chunk file.
then, i will combine two audio files stop button was worked correctly but with set time function is not worked in python server.
there is python server code with socketio


def handle_voice(sid,data): # blob 으로 들어온 데이터 
 # BytesIO를 사용하여 메모리 상에서 오디오 데이터를 로드
 audio_segment = AudioSegment.from_file(BytesIO(data), format="webm")
 directory = "dddd"
 # 오디오 파일로 저장
 #directory = str(names_sid.get(sid))
 if not os.path.exists(directory):
 os.makedirs(directory)
 
 # 오디오 파일로 저장
 file_path = os.path.join(directory, f'{sid}.wav')
 audio_segment.export(file_path, format='wav') 
 print('오디오 파일 저장 완료')`
 


and there is client

Transcode webcam blob to RTMP using ffmpeg.wasm
29 novembre 2023, par hassan moradnezhadI'm trying transcode webcam blob data to a rtmp server from browser by using ffmpeg.wasm .

first, i create a MediaStream.

const stream = await navigator.mediaDevices.getUserMedia({
 video: true,
 });


then, i create a MediaRecorder.


const recorder = new MediaRecorder(stream, {mimeType: "video/webm; codecs:vp9"});
 recorder.ondataavailable = handleDataAvailable;
 recorder.start(0)


when data is available, i call a function called
handleDataAvailable.

here is the function.

const handleDataAvailable = (event: BlobEvent) => {
 console.log("data-available");
 if (event.data.size > 0) {
 recordedChunksRef.current.push(event.data);
 transcode(event.data)
 }
 };


in above code, i use another function which called
transcodeit's goal is going to send data to rtmp server using useffmpeg.wasm.

here it is.

const transcode = async (inputVideo: Blob | undefined) => {
 const ffmpeg = ffmpegRef.current;
 const fetchFileOutput = await fetchFile(inputVideo)
 ffmpeg?.writeFile('input.webm', fetchFileOutput)

 const data = await ffmpeg?.readFile('input.webm');
 if (videoRef.current) {
 videoRef.current.src =
 URL.createObjectURL(new Blob([(data as any)?.buffer], {type: 'video/webm'}));
 }

 // execute by node-media-server config 1
 await ffmpeg?.exec(['-re', '-i', 'input.webm', '-c', 'copy', '-f', 'flv', "rtmp://localhost:1935/live/ttt"])

 // execute by node-media-server config 2
 // await ffmpeg?.exec(['-re', '-i', 'input.webm', '-c:v', 'libx264', '-preset', 'veryfast', '-tune', 'zerolatency', '-c:a', 'aac', '-ar', '44100', '-f', 'flv', 'rtmp://localhost:1935/live/ttt']);

 // execute by stack-over-flow config 1
 // await ffmpeg?.exec(['-re', '-i', 'input.webm', '-c:v', 'h264', '-c:a', 'aac', '-f', 'flv', "rtmp://localhost:1935/live/ttt"]);

 // execute by stack-over-flow config 2
 // await ffmpeg?.exec(['-i', 'input.webm', '-c:v', 'libx264', '-flags:v', '+global_header', '-c:a', 'aac', '-ac', '2', '-f', 'flv', "rtmp://localhost:1935/live/ttt"]);

 // execute by stack-over-flow config 3
 // await ffmpeg?.exec(['-i', 'input.webm', '-acodec', 'aac', '-ac', '2', '-strict', 'experimental', '-ab', '160k', '-vcodec', 'libx264', '-preset', 'slow', '-profile:v', 'baseline', '-level', '30', '-maxrate', '10000000', '-bufsize', '10000000', '-b', '1000k', '-f', 'flv', 'rtmp://localhost:1935/live/ttt']);

 }


after running app and start streaming, console logs are as below.

the problem is when
ffmpeg.wasmtry to execute the last command.

await ffmpeg?.exec(['-re', '-i', 'input.webm', '-c', 'copy', '-f', 'flv', "rtmp://localhost:1935/live/ttt"]).

it just calls aGET Request, I will send further details about this request.

as u can see, i try to use lots of arg sample withffmpeg?.exec, but non of them works.

the network tab in browser, after
ffmpeg.wasmexecute the command is as below.



it send a
GET requesttows://localhost:1935/
and nothing happened after that.

for backend, i use node-media-server and here is my output logs when
ffmpeg.wasmtrying to execute the args

11/28/2023 19:33:18 55301 [INFO] [rtmp disconnect] id=JL569YOF
[NodeEvent on doneConnect] id=JL569YOF args=undefined


at last here are my ques




- 

- how can i achive this option ?
- is it possible to share webcam to rtmp server ?

ffmpeg.wasm - How to do literally anything with a blob url
24 novembre 2024, par SeriousLeeI'm using the ffmpeg.wasm for the first time and I can't get anything working, beyond loading it. I have this function that does nothing in particular (I got it from the vite + react example in the docs, slightly modified) and all I want to do is pass it a blob URL like this
blob:http://localhost:5173/c7a9ea7c-aa26-4f4f-9c80-11b8aef3e81fand run through the function and have it give me anything back. But instead, it hangs on theffmpeg.execcommand and never completes. And yes, I've determined that the input blob does work - it's an 8MB, 12-second long mp4 clip.

Here's the function :


const processOutputVideo = async (videoURL) => {
 const ffmpeg = ffmpegRef.current;

 await ffmpeg.writeFile("input.mp4", await fetchFile(videoURL));
 await ffmpeg.exec(["-i", "input.mp4", "output.mp4"]);

 const fileData = await ffmpeg.readFile("output.mp4");
 const blob = new Blob([fileData.buffer], { type: "video/mp4" });
 const blobUrl = URL.createObjectURL(blob);

 return blobUrl;
 };


And here's the ffmpeg logs from my terminal.
