FFMPEG + HW Acceleration + Kepler GPU Lossless encoding not supported ?
11 juillet 2022, par user2522885I'm curious about FFMPEG and GPU hardware acceleration. My Windows 10 system uses the Asus / nVidia GTX 760 graphics card and Intel i5-2500K CPU. My graphics card claims to be of the Kepler architecture with CUDA 3.0 as shown here.


Instead of going through the hassles of compiling FFMPEG with hw acceleration support i downloaded a pre-compiled binary from here and here.


Next, i tried running a test with hw acceleration options as recommended here :


ffmpeg -y -vsync 0 -hwaccel cuda -hwaccel_output_format cuda -i "input.mkv" -c:a copy -c:v h264_nvenc "output.mp4"


I then received the error message :


[h264_nvenc @ 000001c34eeda8c0] Lossless encoding not supported
[h264_nvenc @ 000001c34eeda8c0] Provided device doesn't support required NVENC features
Error initializing output stream 0:0 — Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height


What am i doing wrong ? For the record i install the CUDA setup file but it made no difference. I am using the latest nVidia drivers.


UPDATE


ffmpeg -h encoder=h264_nvenc

Java - Stream OpenGL Display to Android
24 octobre 2016, par IntektorI tried to solve this problem for days now, but I couldn’t find a working solution. I am trying to stream my game screen (lwjgl) to my android smartphone(I have a frame buffer with the texture), and I already built a fully working packet system and all that stuff. But there are several problem I have no idea how to solve them, first of all, I don’t know in which format I should send the frame buffer, e.g I can’t send it as a Buffered Image, because it doesn’t exist on android. I tried using the jcodec library, but there is no documentation for it, and I didn’t find any examples that fit my case. I think I have to encode and decode it with h264 to make it a realtime live stream(that’s very important). I also heard about ffmpeg (and I found a java library for it : https://github.com/bramp/ffmpeg-cli-wrapper) but there is again no documentation for how to use it to stream it to my mobile. Also I have the problem, that when would get the frames to my smartphone, how can I make them load by the graphics card
Here is what I have done so far :
My packet :public class ImagePacketToClient implements Packet {
public byte[] jpgInfo;
public int width;
public int height;
BufferedImage image;
public ImagePacketToClient() {
}
public ImagePacketToClient(BufferedImage image, int width, int height) {
this.image = image;
this.width = width;
this.height = height;
}
@Override
public void write(DataOutputStream out) throws IOException {
ByteArrayOutputStream baos = new ByteArrayOutputStream();
ImageIO.write(image, "jpg", baos);
baos.flush();
byte[] bytes = baos.toByteArray();
baos.close();
out.writeInt(bytes.length);
for (byte aByte : bytes) {
out.writeInt(aByte);
}
}
@Override
public void read(DataInputStream in) throws IOException {
int length = in.readInt();
jpgInfo = new byte[length];
for (int i = 0; i < length; i++) {
jpgInfo[i] = in.readByte();
}
}The code that gets called after the rendering has finished : mc.framebuffer is the frame buffer I can use :
ScaledResolution resolution = new ScaledResolution(mc);
BufferedImage screenshot = ScreenShotHelper.createScreenshot(resolution.getScaledWidth(), resolution.getScaledHeight(), mc.getFramebuffer());
ImagePacketToClient packet = new ImagePacketToClient(screenshot, screenshot.getWidth(), screenshot.getHeight());
PacketHelper.sendPacket(packet, CardboardMod.communicator.connectedSocket);
screenshot.flush();
public static BufferedImage createScreenshot(int width, int height, Framebuffer framebufferIn)
{
if (OpenGlHelper.isFramebufferEnabled())
{
width = framebufferIn.framebufferTextureWidth;
height = framebufferIn.framebufferTextureHeight;
}
int i = width * height;
if (pixelBuffer == null || pixelBuffer.capacity() < i)
{
pixelBuffer = BufferUtils.createIntBuffer(i);
pixelValues = new int[i];
}
GlStateManager.glPixelStorei(3333, 1);
GlStateManager.glPixelStorei(3317, 1);
pixelBuffer.clear();
if (OpenGlHelper.isFramebufferEnabled())
{
GlStateManager.bindTexture(framebufferIn.framebufferTexture);
GlStateManager.glGetTexImage(3553, 0, 32993, 33639, pixelBuffer);
}
else
{
GlStateManager.glReadPixels(0, 0, width, height, 32993, 33639, pixelBuffer);
}
pixelBuffer.get(pixelValues);
TextureUtil.processPixelValues(pixelValues, width, height);
BufferedImage bufferedimage;
if (OpenGlHelper.isFramebufferEnabled())
{
bufferedimage = new BufferedImage(framebufferIn.framebufferWidth, framebufferIn.framebufferHeight, 1);
int j = framebufferIn.framebufferTextureHeight - framebufferIn.framebufferHeight;
for (int k = j; k < framebufferIn.framebufferTextureHeight; ++k)
{
for (int l = 0; l < framebufferIn.framebufferWidth; ++l)
{
bufferedimage.setRGB(l, k - j, pixelValues[k * framebufferIn.framebufferTextureWidth + l]);
}
}
}
else
{
bufferedimage = new BufferedImage(width, height, 1);
bufferedimage.setRGB(0, 0, width, height, pixelValues, 0, width);
}
return bufferedimage;
}Honestly I don’t want to use this Buffered Image Stuff, because it halfs my framerate, and that’s not good.
And I don’t have any code for my android application yet, because I couldn’t figure out how I could get this image recreated on Android, and how to load it after that.
I hope you understand my problem and I am happy about every tip you can give to me :) -
improve video size ffmpeg webcam stream
18 juin 2020, par Wolfgang EnfieldI am trying to use a webcam Logitech Quickcam 9000 to do IRL stream from a Raspberry 3 using Raspberry Pi OS current version, I have FFmpeg installed and no matter what I try the video resolution is never bigger than 320x240 the webcam can output 1600x1200 the output of v4l2-ctl —list-formats-ext
