• Fuji .mov file converted by ffmpeg doesn't play in Windows Media Player [closed]

  30 août 2023, par glipster

  My Fuji X-T3 generates an FHD movie as a .mov with HEVC video and PPM audio. The new Media Player on Windows won't play this (without buying a codec) so I convert it to .mp4 using ffmpeg CLI (ffmpeg -i in.mov out.mp4). The resulting .mp4 file uses AVC video and AAC LC audio. This plays fine in VLC, but will not play in Windows Media Player nor Media Player. I've experimented with various options, but nothing seems to work.
For the original source .mov file, MediaInfo identifies 3 streams :
1stVid : English, 201Mb/s, 1920*1080 (16:9), at 29.970 FPS, HEVC (Main10@L5.2@High)
1stAud : english, 2304 kb/s, 48.0 hKz, 24 bits, 2 channels,PCM (Little/Signed)
1 : QuickTime TC

  


  The Output .mp4 file shows :
1stVid : English 3312kb/s, 1920*1080 (16:9) at 29.970 FPS, AVC (High 10@L4)(CABAC/4 RefFrames)
1stAud : English 132 kb/s, 48.0 kHz, 2 channels, AC LC
1 : QuickTime TC

  


  Using ffmpeg CLI, I tried changing the bitrates for the video and audio, I tried removing the timecode stream, tried a different AAC codec, tried moving the metadata to the front (-movflags faststart), also tried -strict experimental, tried first converting to .mkv (which does work) and then converting to .mp4 (with and without copy). I had hoped one of these might work ; but nothing has worked thus far.

  


  Has anyone else solved this problem ? Any help would be greatly appreciated.

  


• How to config FFmpeg for xrgb and Aver Media capture card [closed]

  12 mai 2023, par Plotter Desalor

  I'm trying to use FFmpeg through ffplay to display a capture card output as lossless as possible.

  


  My capture card is named "Live Gamer Ultra-Video"

  


  In OBS, the NV12, YV12, P010 and YUY2 lead to blurriness around text and fine pixels edges, but the XRGB one offer clear output. So I've tried to focus on this mode with FFmpeg as the default one lead to same blurriness seen in OBS.

  


  Running "ffmpeg -f dshow -list_options true -i video="Live Gamer Ultra-Video" show me this result
(i've only kept line with wanted resolution)

video=Live Gamer Ultra-Video: Immediate exit requested


  


  "unknown compression type 0xE436EB7D" is a pretty bad start but from https://trac.ffmpeg.org/ticket/6279 I could figured out it was just unproperly parsed RGB24 format

  


  But if I run a very simple "ffplay -f dshow -i video="Live Gamer Ultra-Video" -pixel_format rgb24"
I got this output

  How could I use rgb format with this capture card ?

  


  If not possible, any other format leading to proper output would be ok too.
I've tried parameters from this topic Capture full-range/lossless rgb frame from capture card that supports NV12 and YUYV output without any good result sadly.

  


• i am trying to make my ipcamera stream over webrtc usingnodejs and kurento media server

  5 mai 2023, par vishnu nair

  i am new at webrtc and rtsp, while trying to make a project on webrtc i came to a halt in my code and after weeks of online search adn usng chatgpt am still not able to resolve my problem. I want to stream my ipcamera to webrtc but the code is not working properly.am not above to start the stream.

  


  the code is given below

  


  const wrtc = require('wrtc');
const kurento = require('kurento-client');
const mqtt = require('mqtt');
const node_ffmpeg_stream = require('node-ffmpeg-stream');

const mqttonline_connection = require('../../mqttconnection/online_mqtt_connection');

    // Create RTSP source and connect it to the WebRTC endpoint
    const rtspEndpoint = await pipeline.create('RtspEndpoint', {uri: RTSP_URL});
    rtspEndpoint.connect(webRtcEndpoint);

    // Start streaming
    webRtcEndpoint.gatherCandidates();

    // Subscribe to ICE candidate events and send them via MQTT
    webRtcEndpoint.on('OnIceCandidate', event => {
      const candidate = kurento.getComplexType('IceCandidate')(event.candidate);

      clientonline.publish('sdp', JSON.stringify(candidate));
    });
