  • FFMPEG mkv to mp4 conversion lacks audio

    28 septembre 2017, par Landslyde

    I used ffmpeg to convert an mkv file to mp4 using this command line :

    ffmpeg -i input.mkv -c copy file-1.mp4

    The resulting mp4 plays fine (video and audio) on Linux Mint's Xplayer. But after uploading file-1, it played with no audio. So I uploaded another mp4 file-2, one I didn’t have to convert, and it plays both video and audio without a problem. So whatever’s going on with file-1 seems to be with my use of ffmpeg.

    The player I’m using is called afterglow. But the HTML5 player handles these two files the same way : file-1 & file-2

    Does anyone know why the ffmpeg converted file is soundless when played online ? Is there a different conversion command that ensures converted mkv files will play with sound by online players ?

  • Streaming Encoded MPEG-4 live video from a web camera using RTP in C++

    20 juin 2022, par Maad A.Galil

    I have been working on building a video streamer from a webcam using RTP protocol in C++ language in Linux. I was able to use opencv to take frames from the webcam and send them frame by frame to a client app that shows those frames one by one using the same frame per second parameter.

    


    But that is mostly a MJPEG kind of transfer as the encoding used is JPEG encoding with a specific quality for each frame. However, I would like to use MPEG-4 encoding before transferring the video. After a deep search online I found out that ffmpeg is the best for such purpose. But the samples online mostly work through a command line interface to capture a webcam video and save it as a video file with the given encoding and format.

    


    Is there a possibility to encode the webcam "LIVE", and get byte data while encoding the camera stream ?

    


    I would like to use those byte data to transfer it using RTP for example. And then I would like to decode the received byte data and show the video using opencv imshow function for example.
