  • ffmpeg convert one png to DNxHD

    15 mars 2019, par bcvery1

    I’m trying to create a DNxHD file from one PNG file. The output should be "24000/1001" fps, 1920x1080, using the dnxhd codec. Every frame should be the same. The outputted stream must be 20 seconds in length.

    I have a solution which uses filter_complex to loop the PNG for each frame, however this results in extremely large files. Given that I will be combining possibly multiple hundred DNxHD files into one AAF file, the output file size is too large.

    Is there any improvement I can make on the command below which would achieve this file size reduction ?

    ffmpeg -i INFILE.png -y -nostdin -an -vcodec dnxhd -pix_fmt yuv422p -vb 36M  -framerate 24000/1001 -filter_complex loop=479:1:0 OUFILE.dnxhd

    I do not know ffmpeg all that well, this command has been constructed by copying parts of commands I have found online.

  • FFMPEG merge one audio and one video file [duplicate]

    29 mars 2020, par Karl R

    I am trying to get this to work for a few hours and am having no luck. I have two .mp4 files - one is audio and one is video. All I want to do is merge them into one file so the audio and video play together. I know I am close but I keep getting stuck on "Cannot find a matching stream for unlabeled input pad 1 on filter Parsed_hstack_0".

    My command I am using is :

    .\ffmpeg.exe -y -i .\camera.mp4 -i .\screen.mp4 -filter_complex hstack output.mp4

    Output of each file type is attached.

    Thank you for your help - we found a bug in a screen recording app on our AMD laptops and this will helps us with a temporary fix. I work at a tech college and we are scrambling to get online videos going for the students to learn remotely.

  • RTP Packets to test RTSP Server

    6 mars 2019, par stackjohnny

    I am new to this domain, but I successfully setup RTSP server in one of the container and when running

    ./rtsp_media_server -l 8445 -s stream1 -p 8000

    it is working fine. where 8445 is the expose port, stream1 is the stream name and 8000 is the intake port

    URL : rtsp://<host>:8445/stream1</host>

    But I need RTP packets to be sent to port 8000 so that I can test the my rtsp media server perfectly.

    Do any online rtp server provides the same ?

    I can see many sample rtsp media server is there like rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov , which I can test in VLC media player. but not sure how to do with RTP packets.

    Please correct me if my understanding is wrong and guide me.
