Unable to use ffmpeg.run on rtsp input stream #67

Open AbhinavA10 opened 4 years ago

AbhinavA10 commented 4 years ago

Describe the bug Unable to use ffmpeg.run to use rtsp stream as the input, and output the transcoded stream over an http stream using mpeg1video encoding. In ffmpeg, I can do the following

ffmpeg  -i rtsp://192.168.0.101/av0_1 -f mpegts -codec:v mpeg1video -b 800k -r 30 http://localhost:8081/password

However, when I try doing the same thing using ffmpeg.wasm, I get the following:

[info] load ffmpeg-core
[info] ffmpeg-core loaded
starting
[info] ffmpeg command: ./ffmpeg -nostdin -hide_banner -i rtsp://192.168.0.101/av0_1 -f mpegts -codec:v mpeg1video -b 800k -r 30 http://localhost:8081/password
[ffmpeg-stdout] Assertion failed: undefined
[ffmpeg-stderr] Assertion failed: undefined
[ffmpeg-stdout] RuntimeError: abort(Assertion failed: undefined). Build with -s ASSERTIONS=1 for more info.
[ffmpeg-stderr] RuntimeError: abort(Assertion failed: undefined). Build with -s ASSERTIONS=1 for more info.
// then prints out ffmpeg-core.js file

The code I used is below: example_stream.js:

const { createFFmpeg } = require('@ffmpeg/ffmpeg');
const ffmpeg = createFFmpeg({ log: true });
(async () => {
    await ffmpeg.load();
    console.log("starting");
    await ffmpeg.run("-i rtsp://192.168.0.101/av0_1 -f mpegts -codec:v mpeg1video -b 800k -r 30 http://localhost:8081/password");
  })();

To Reproduce Steps to reproduce the behavior:

  1. Create a new node project 2.npm install "@ffmpeg/ffmpeg"
  2. Run code above
  3. See error

Expected behavior Output similar to ffmpeg terminal command:

eng6@eng6-ThinkPad-P50s:~$ ffmpeg  -i rtsp://192.168.0.101/av0_1 -f mpegts -codec:v mpeg1video -b 800k -r 30 http://localhost:8081/password

Right now rtsp/rtmp is not supported due to the external libraries is unable to integrate with ffmpeg.wasm, I am still looking for possibilities.

@jeromewu jeromewu Is it possible to Screen Capture API and MediaStream Recording API to record the screen and then use FFmpeg.wasm or ffmpeg.js to stream any RTMP server like youtube, Facebook at once?

Same request here, see https://github.com/ffmpegwasm/ffmpeg.wasm/issues/61

Hi, does ffmpeg.wasm support rtmp stream as input now? I am encountering a connection refused problem now: (async () => { await ffmpeg.load(); await ffmpeg.run( '-re', '-i', 'rtmp://x.xx.xx.xxx:1935/live/stream_id', ... ); })(); However, I got following error: [fferr] [tcp @ 0x1a67100] Starting connection attempt to x.xx.xx.xxx port 1935 [fferr] [tcp @ 0x1a67100] Connection attempt to x.xx.xx.xxx port 1935 failed: Connection refused [fferr] [tcp @ 0x1a67100] Connection to tcp://x.xx.xx.xxx:1935 failed: Connection refused [fferr] [rtmp @ 0x1a66c40] Cannot open connection tcp://x.xx.xx.xxx:1935 [fferr] rtmp://x.xx.xx.xxx:1935/live/stream_id: Connection refused [ffout] FFMPEG_END

I have no problem connecting to the rtmp stream using ffmpeg itself in command line though. Any help would be greatly appreciated!

@jeromewu is rtmp supported now?

Bec-k commented 1 year ago

Is rtsp working now or not implemented yet?
