  • Is ffmpeg a good upscaler from SD to HD ? [closed]

    15 août 2014, par user3928079

    Is ffmpeg a good upscaler to convert SD videos to HD ?

    I use the AVANTI GUI. I installed it and put the ffmpeg and ffplay exe into the folder ffmpeg in the program folder. What I know is that you can only preserve the detail when you upscale from SD to HD. You don’t really gain any additional information. TV companies like Samsung, Sony, LG, Panasonic, Sharp, and others refuse to think so and push the boundaries of upscaling so that additional information can be added when the image is upscaled from SD to HD and HD to 4K and so on and so forth. I’ve run a test through the AVANTI ffmpeg GUI.

    Codec : XVID to H.264
    Bitrate : 1640 kbps to 6000 kbps
    Resolution : 640x480 to 1440x1080
    Format : AVI to M4V
    Audio Codec : AC3 to AAC
    Audio Bitrate : 192 kbps
    Audio Frequency : 48000 Hz
    Upscale method : Spline

    Will this upscale method work in any way with converting SD video to HD video. There’s a lot of SD content out that haven’t made the transition to, or probably never will be, HD.

  • How can I stream then play YUV format with/without VLC/FFMPEG ?

    13 janvier 2023, par orfruit

    I'm able to play a local YUV file through VLC (as expected)

    &#xA;

    .\vlc.exe --demux rawvideo --rawvid-fps 25 --rawvid-width 480 --rawvid-height 360 --rawvid-chroma I420 out.yuv&#xA;

    &#xA;

    Also FFPLAY is playing well

    &#xA;

    .\ffplay.exe -f rawvideo -pixel_format yuv420p -video_size 480x360 out.yuv&#xA;

    &#xA;

    Conversion to YUV was done with FFMPEG

    &#xA;

    .\ffmpeg.exe -i "video.mp4" -c:v rawvideo -pixel_format yuv420p out.yuv&#xA;

    &#xA;

    However, I'm not able o stream it and play'it over local network.&#xA;I know, it sounds crazy :) but I plan to use VLC as a monitor/debugger for some YUV data.

    &#xA;

    The original MP4 file is streamed/played fine with VLC (test on the same computer)

    &#xA;

    .\vlc.exe "video.mp4" --sout="#std{access=http, mux=ts, dst=:55555/}"&#xA;.\vlc.exe http://192.168.0.174:55555/&#xA;

    &#xA;

    So the big question !&#xA;How can I stream the YUV format and VLC recognise an play it as well ?

    &#xA;

    All that I tried with VLC is not playable.

    &#xA;

    Thanks for any hints !
