  • How to add a new stream after avformat_write_header function is called ?

    26 février 2019, par hellkni9ht

    I have several video sources that produce video frames. Each video source should be represented as the separate video stream inside an output video file(mp4 or mpegts).
    The problem is that I should specify the exact number of streams and create them before avformat_write_header function is called. If I try to add the stream after, I will get crash inside av_interleaved_write_frame. Is any way to add a stream on the fly ? Maybe there are some muxer options that I should specify ? Thanks in advance for your answers.

    I am trying to resize a high res video into 480x ??? and with to maintain aspect ratio and also without losing quality. I wish to maintain the original quality of the video. I tried this command line but it loses quality.

    ffmpeg -i a.mp4 -filter:v scale=480:-1 -c:a copy b.mp4

    I got some filters and options from google search such as -qscale,-sameq etc but it is not working.

    Can you please tell me the exact command ?

    Thanks

    EDIT : I also need to place two videos one below the other and wish to know if there is any such option in ffmpeg coz I cannot find anything on google.
