Building FFmpeg with NVIDIA GPU Hardware Acceleration in docker image, cannot load libnvcuvid.so.1 and libnvidia-encode.so.1
22 mars 2023, par konovificationI'm trying to build FFmpeg with NVIDIA GPU Hardware Acceleration following these instructions : https://docs.nvidia.com/video-technologies/video-codec-sdk/ffmpeg-with-nvidia-gpu/index.html#compiling-for-linux. The Docker image I'm using is
nvidia/cuda:12.0.1-devel-ubuntu20.04

Running the test command
ffmpeg -y -vsync 0 -hwaccel cuda -hwaccel_output_format cuda -i bbb.mp4 -c:a copy -c:v h264_nvenc -b:v 5M output.mp4, I get the following output :

The shared libraries are not part of the docker image. What are my options to add them ?

FFMPEG Output File is Empty Nothing was Encoded (for a Picture) ?
4 mars 2023, par Sarah SzaboI have a strange issue effecting one of my programs that does bulk media conversions using ffmpeg from the command line, however this effects me using it directly from the shell as well :


ffmpeg -i INPUT.mkv -ss 0:30 -y -qscale:v 2 -frames:v 1 -f image2 -huffman optimal "OUTPUT.png"
fails every run with the error message :
Output file is empty, nothing was encoded (check -ss / -t / -frames parameters if used)

This only happens with very specific videos, and seemingly no other videos. File type is usually .webm. These files have been downloaded properly (usually from yt-dlp), and I have tried re-downloading them just to verify their integrity.


One such file from a colleague was : https://www.dropbox.com/s/xkucr2z5ra1p2oh/Triggerheart%20Execlica%20OST%20%28Arrange%29%20-%20Crueltear%20Ending.mkv?dl=0


Is there a subtle issue with the command string ?


Notes :

moving

removing

Codec AVOption huffman (Huffman table strategy) specified for output file #0 (TEST.png) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some encoder which was not actually used for any stream.

Decode a proprietary (Genetec) H264 network video stream
2 mars 2023, par al_muktharI have incoming byte streams probably encoded in H264 from a Genetec camera through a websocket in my spring boot application,


I need to decode the incoming H264 streams to transmit the video to my frontend clients.
I have tried using javaCV/FFMpeg but nothing works.


I think, Genetec is using some custom encoding which is different from normal encoding


Any help would be appreciated


this is the part of hex dump received through socket

UPDATE TO THE CODE


1st Packet find here
2nd Packet find here


I have updated the code as per one of the comment to read only MDAT box to retrieve H264 stream from the incoming bytes[] through the socket, now I send only MDAT box contents (next byte after MDAT box)


public Map.Entry> hasMdat(byte[] byteArray) {
 for (int i = 0; i < byteArray.length - 3; i++) {
 if (byteArray[i] == (byte) 109 &&
 byteArray[i + 1] == (byte) 100 &&
 byteArray[i + 2] == (byte) 97 &&
 byteArray[i + 3] == (byte) 116) {

 return Map.entry(true, Arrays.asList(i, i + 1, i + 2, i + 3));
 }
 }
 return Map.entry(false, List.of(0));
}


This is my code which handles the byte stream


initSocketConnection(new VideoStreamCallback() {
 @Override
 public void onVideoStreamReceived(byte[] bytes) {
 
Map.Entry> b = hasMdat(bytes);
 if (b.getKey()) {
 byte[] b1 = Arrays.copyOfRange(bytes, b.getValue().get(3) + 1, bytes.length);
 //write b1 back to client using spring SSE
 
 }

 }
 });
