ffmpeg timecode based on filename
9 mars 2023, par marvenI have xxxxx videofiles that need to get a timecode (for working in premiere)
The filenames are all like this 2023-03-08 12.59.59 AndSomeRandowNumbers.
Is that possible with ffmpeg ?
Or if that is not possible : can ffmpeg use an other date from the metadata and use that as timecode (with exiftool is possible to use the filename and write it as creation date, and other, but not as timecode) ?


ffmpeg -i file.mov -map 0 -map -0:d -c copy -timecode 02:10:22:33 outputfile.mov
that is the code that works to change the timecode to 02:10:22:33

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

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
 
 }

 }
 });
