    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • Render Multiple Gifs with ffplay/ffmpeg in Winform

    17 juin 2019, par Purqs

    I’m trying to get x number of animated gifs to render on like a Panel or PictureBox and using transparency that is in each gif. I’ve tried a couple approaches but am not super famiular with ffmpeg and such. Below is some code that I use to get it to render inside a panel, but I can’t figure out how to get like 5 gifs to stack/layer on one another and still render as you would expect.

    I need/want this to render in the form and not outputted. I am a little confused to why the ffplay.exe doesn’t use the -i command and that might be why i can’t get it to render. any ideas ?

    Working example below.

    using System;
    
using System.Collections.Generic;
    
using System.ComponentModel;
    
using System.Data;
    
using System.Drawing;
    
using System.Linq;

using System.Threading;
    
using System.IO;
    
using System.Reflection;
    
using System.Runtime.InteropServices;
    
using System.Drawing.Text;
    
using System.Text.RegularExpressions;
    
using System.Configuration;
    
using Microsoft.Win32;
    
using System.Windows.Forms.VisualStyles;
    

    
//FOR THIS EXAMPLE CREATE FORM HAVE BUTTON ON IT AND PANEL.
    
//button: button's click is "button1_Click"
    
//panel: Needed to output the render on it.
    
//FILES:
    
//Test.Gif
    
//These ff files came from the ffmpeg offical site.
    
//ffplay.exe //currently using
    
//ffmpeg.exe //thinking i need to use to get it how I want.
    
//I most of the code below from https://stackoverflow.com/questions/31465630/ffplay-successfully-moved-inside-my-winform-how-to-set-it-borderless which was a good starting point.
    

    
namespace Test_Form
    
{
    
    public partial class Form1 : Form
    
    {
    
        [DllImport("user32.dll", SetLastError = true)]

        private static extern IntPtr SetParent(IntPtr hWndChild, IntPtr hWndNewParent);
    

    

    
        //Process ffplay = null;
    

    
        public Form1()
    
        {
    
            InitializeComponent();
    
            Application.EnableVisualStyles();

            ffplay.StartInfo.CreateNoWindow = true;
    
            ffplay.StartInfo.RedirectStandardOutput = true;
    
            ffplay.StartInfo.UseShellExecute = false;
    

    
            ffplay.EnableRaisingEvents = true;
    
            ffplay.OutputDataReceived += (o, e) => Debug.WriteLine(e.Data ?? "NULL", "ffplay");
    
            ffplay.ErrorDataReceived += (o, e) => Debug.WriteLine(e.Data ?? "NULL", "ffplay");
    
            ffplay.Exited += (o, e) => Debug.WriteLine("Exited", "ffplay");
    
            ffplay.Start();
    

    
            Thread.Sleep(1000); // you need to wait/check the process started, then...
    

    
            // child, new parent
    
            // make 'this' the parent of ffmpeg (presuming you are in scope of a Form or Control)
    
            SetParent(ffplay.MainWindowHandle, this.Handle);
    

    
            // window, x, y, width, height, repaint
    
            // move the ffplayer window to the top-left corner and set the size to 320x280
    
            MoveWindow(ffplay.MainWindowHandle, 800, 600, 320, 280, true);
    

    
            SetParent(ffplay.MainWindowHandle, this.panel1.Handle);
    
            MoveWindow(ffplay.MainWindowHandle, -5, -30, 320, 280, true);
    
        }
    

    
//runs the FFplay Command
    
private void button1_Click(object sender, EventArgs e)
    
        {
    
            FFplay();
    

    
        }
    

    
        private void Form1_FormClosed(object sender, FormClosedEventArgs e)
    
        {
    
            try { ffplay.Kill(); }
    
            catch { }
    
        }
    
    }

    I would like the button to allow me to add any number of gifs (like 5 or 10) all to the same area and have them being animated with their transparent showing what is under that gif.

    So for example I could have a circle image, then a spinning/loading transparent gif on top, and then a gif that counts up/down on top of that one to give me the effect of a count-down.

    Thanks for all the help !

  • Issues when decoding video via ffmpeg with dxva2

    5 janvier 2016, par CD83

    I have successfully implemented a video player using ffmpeg. I am now trying to use hardware decoding but I’m facing a couple issues.
    I found a post that I followed as a starting point here : http://comments.gmane.org/gmane.comp.video.ffmpeg.libav.user/13523

    I have updated the code that setup the necessary stuff for the decoder. The updated code is available here : https://drive.google.com/file/d/0B5ufHdoDzA4ieVk5UVpxcDNzRHc/view?usp=sharing

    And this is how I’m using it to initialize the decoder :

    // Prepare the decoding context
    
AVCodec *codec = nullptr;
    
_codecContext = _avFormatContext->streams[_streamIndex]->codec;
    
if ((codec = avcodec_find_decoder(_codecContext->codec_id)) == 0)
    
{
    
    std::cout &lt;&lt; "Unsupported video codec!" &lt;&lt; std::endl;
    
    return false;
    
}
    

    
_codecContext->thread_count = 1;  // Multithreading is apparently not compatible with hardware decoding
    
InputStream *ist = new InputStream();
    
ist->hwaccel_id = HWACCEL_AUTO;
    
ist->hwaccel_device = "dxva2";
    
ist->dec = codec;
    
ist->dec_ctx = _codecContext;
    
_codecContext->coded_width = _width;
    
_codecContext->coded_height = _height;
    

    
_codecContext->opaque = ist;

{
    
    std::cout &lt;&lt; "Video codec open error" &lt;&lt; std::endl;
    
    return false;
    
}

    And here is the definition of GetHwFormat referenced above :

    AVPixelFormat GetHwFormat(AVCodecContext *s, const AVPixelFormat *pix_fmts)
    
{
    
    InputStream* ist = (InputStream*)s->opaque;
    
    ist->active_hwaccel_id = HWACCEL_DXVA2;
    
    ist->hwaccel_pix_fmt = AV_PIX_FMT_DXVA2_VLD;
    
    return ist->hwaccel_pix_fmt;
    
}

    When I open an mp4 (encoded in h264) video that is HD resolution or less, everything seems to be working fine. However, as soon as I try higher resolution videos like 3840x2160, I get the following errors repeatedly :

    Failed to execute: 0x80070057
    
Hardware accelerator failed to decode picture

    I also start getting the following errors after a few seconds :

    co located POCs unavailable

    And the video is not displayed properly : I get a lot of artifacts all over the video and it is lagging. I checked the first error in the ffmpeg source code. It seems that IDirectXVideoDecoder_Execute fails because of an invalid parameter. Since this is happening withing ffmpeg, there must be something that I’m missing but I can’t figure out what. The only relevant post that I found with this error was because of multithreading but I set the thread_count to 1 before opening the codec.

    This issue is happening on my main computer which has the following specs :

    • i7-4790 CPU @ 3.6GHz
    • RAM 16 GB
    • Intel HD Graphics 4600
    • Windows 8.1

    The same issue is not happening on my second computer which has the following specs :

    • i7 4510U @ 2GHz
    • RAM 8 GB
    • NVIDIA GeForce GTX 750Ti
    • Windows 10

    If I use DXVAChecker on my main computer, it says that my graphics card supports DXVA2 for H264_VLD_*, and I can see that the calls to the Microsoft API are being made (DXVA2_DecodeDeviceCreated, DXVA2_DecodeDeviceBeginFrame, DXVA2_DecodeDeviceGetBuffer, DXVA2_DecodeDeviceExecute, DXVA2_DecodeDeviceEndFrame) while my video is playing.

    I also don’t see any increase of GPU usage (on either computer) between the version with hardware decoding and the version without ; however, I do see a decrease in CPU usage (not as much as I was expecting though). This is also very strange.

    Note that I tried both the Windows release available on the FFmpeg website, and a version that I compiled with —enable-dxva2. I have searched a lot already but I was unable to find what I’m doing wrong.

    Hopefully, someone can help me, or maybe point me to a better example ?
