nvenc encoder performed resolution 2560 * 1440 encoding yuv444 failed ？
8 novembre 2022, par Travis990NVIDIA Gefore GTX 1660Ti graphics card, I use video-sdk-samples for HEVC encoding, YUV format : NV_ENC_BUFFER_FORMAT_YUV444, resolution “1920 * 1080” and “3840 * 2160” resolution encoding is successful, but resolution 2560*1440 encoding, prompting error info :NV_ENC_ERR_INVALID_PARAM, I do not know where the problem lies ?


void NvEncoder::DoEncode(NV_ENC_INPUT_PTR inputBuffer, std::vector<bool> &vKeyFrame, std::vector> &vPacket, NV_ENC_PIC_PARAMS *pPicParams)
{
 NV_ENC_PIC_PARAMS picParams = {};
 if (pPicParams)
 {
 picParams = *pPicParams;
 }
 picParams.version = NV_ENC_PIC_PARAMS_VER;
 picParams.pictureStruct = NV_ENC_PIC_STRUCT_FRAME;
 picParams.inputBuffer = inputBuffer;
 picParams.bufferFmt = GetPixelFormat();
 picParams.inputWidth = GetEncodeWidth();
 picParams.inputHeight = GetEncodeHeight();

error:

change video resolution to specific resolution using ffmpeg in python
2 novembre 2022, par davidI am trying the change the resolution of some videos. The original video resolution is 1920x1080. first, I have to change the resolution to 640X480. for this I used the following code :


subprocess.call(['ffmpeg.exe', '-y', '-i', pname1, '-vf', 'scale=-1:480,setsar=1:1', '-c:v','libx264', '-c:a', 'copy', pname2])


when I used this code it produces a file that I cannot open and when I try to open it in cmd it said : "Invalid data found when processing input".
I changed the code to this to have 640X480 :


subprocess.call(['ffmpeg.exe', '-y', '-i', pname1, '-vf', 'scale=640:-2,setsar=1:1', '-c:v','libx264', '-c:a', 'copy', pname2])


but the output is 640X360, what is the problem and how can I change the resolution from 1920x1080 to 640x480 ?
after that I have to change the resolution of videos to their original resolution (1920x1080) again.

28 octobre 2022, par davidI have a folder that contains videos with a resolution of 1080 and different bitrates. I am trying to change their resolution to 480 and using the following code :


subprocess.call(['ffmpeg.exe','-i', pname1,'-vf', 'scale=-1:480,setsar=1:1','-c:v','libx264','-pix_fmt' ,'yuv420p','-b:v', str(cnt)+'K', '-bufsize', str(cnt)+'K' ,'-minrate', str(cnt)+'K','-maxrate', str(cnt)+'K', '-x264opts','keyint=60:min-keyint=60','-preset', 'veryfast', '-profile:v', 'high', '-f', 'hls', '-hls_time', '2', '-hls_list_size','0', pname2])


but it produces noting in the related filename (
pname2). it also shows no error.
what is the problem and how can I change the resolution to 480 ?
