  • FFmpeg : Encode x264 with AMD GPU on Windows ?

    20 septembre 2023, par ZeroTek

    I am currently trying to record a Video on my Lenovo Laptop with its Built-In Webcam using FFmpeg on Windows 10. One of my goals is to keep the CPU Usage as low as possible, that's why i want to push the h264 encoding to the GPU. 
Now it gets a bit tricky here with my Laptop. Because it uses two GPUs. The first GPU is a Intel HD 5500 Graphics Unit as Part of the CPU. This one is most likly used for non-demanding Applications like office etc. to save Energy. The other one is a AMD R5 M330 that will be used for graphic intense applications like gaming.

    



    Currently, i am using the following command to encode the Webcam Stream on the Intel HD GPU :

    



    ffmpeg -f dshow -vcodec mjpeg -video_size 1280x720 -framerate 30 video="Lenovo EasyCamera":audio="Mikrofon (Realtek High Definition Audio)" -c:v h264_qsv -g 60 -q 28 -look_ahead 0 -preset:v faster -c:a aac -q:a 0.6 -r 30 output.mp4


    



    This does work so far but it seems this GPU does not have enough Power to keep up with the framerate on higher bitrates or with a high amount of i-frames. The Video starts lacking and skipping frames. If i am using CPU encoding everything works smooth.

    



    Now that my Laptop got that second AMD GPU with a lot more Power it would be a nice Try to encode on that one, but i can't find any information about how to encode on AMD Hardware on Windows 10. So my question is : How does the ffmpeg command look like to use AMD Hardware for h264 encoding ?

    


  • ffmpeg rtsp over http not working

    17 novembre 2017, par kooli

    I put this conf on ffserver

    HTTPPort 1234
    
RTSPPort 1235
    
<stream>
    
Format rtp
    

    
Feed feed1.ffm
    
VideoCodec libx264
    
VideoFrameRate 24
    
VideoBitRate 100
    
VideoSize 480x272
    
AVOptionVideo flags +global_header
    
</stream>

    I stream with this command

    ffmpeg -i file.h264 http://127.0.0.1:1234/feed1.ffm

    When I watch this stream I can watch via udp and tcp on this url :

    rtsp://127.0.0.1:1235/live.h264

    but i want to stream with rtsp over http(http tunneling).

    How can I do it please ??

  • ffmpeg cache whole video stream and save

    19 juillet 2016, par Luiz

    I have a security DVR that can stream a video recording using the RTSP protocol. I can record the playback using ffmpeg and save it to a file, but for a 20 min video, I have to watch the video to save or wait the whole playback time.
    I’m using :

    ffmpeg -i "rtsp://mystream" -r 15 -acodec copy -vcodec copy myvideo.mp4

    to do this

    Is there any way to buffer the whole stream and just save it to a file using ffmpeg, without the need to watch or wait the whole 20 minutes playback ? I don’t need to reencode anything since the stream video format is good enough for me.

    Thanks in advance
