  • ffmpegintrop namespace not recognized

    13 mars 2016, par Muhammad Touseef

    I used the sample ffmpegintrop project provided by Microsoft, I followed all steps of building and compilation and it was succesfully built. But then I tried to run the project it fails to build giving error : ’type or namespace ffmpegintrop cannot be resolved’. As you can see in the attached image below that using statement of the namespace is also giving error that it is not working. Please help.

  • 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 ?

    


  • images->video->web canvas : RGB/YUV issues

    5 février 2016, par nrob

    We’ve written an web app which :

    1. takes 3D, time dependent weather data
    2. tiles each 3D time point to make a 2D frame (written out as a png image)
    3. stitches these frames together into a video (using ffmpeg/avconv)
    4. streams this video into a web app
    5. polls the canvas for frames
    6. sends the frames to the GPU where they are converted back to 3D and ray traced

    You can see the app here, code here and you can see the data video here

    Currently the pngs are written as RGB images, the video codec is in YUV and getting frames from the canvas returns RGB. As such there is a significant loss of information due to the conversion between image spaces.

    Does anyone have suggestions what is the best way round this ?

    I’ve tried a bunch of RGB video codecs, but I can’t get any to work, and I don’t know if the web browser will support it anyway. Can anyone suggest a good RGB codec (both lossy and lossless would be great)

    Also, is it possible to write to YUV images/read them from a video canvas in HTML5 ?

    Ultimately, I don’t even want anything to do with images/videos, I’m just hacking the codecs to stream/compress large animated 3D data volumes
