It is very nice to support H/W acceleration in ffmpeg. Thank you so much.
Anyways, I have an issue:
- I used -c:v h264_nvenc to encode 4kx4k video to MP4.
- Then when I try to decode using ffmpeg -hwaccel cuvid -c:v h264_cuvid, it looks only key frame was decoded.
I check the video with VLC, and see the media information, the display resolution is 4096x4096. But buffer dimension is 4096x4098.
I wonder this issue belongs to ffmpeg or nvidia video codec. As I know Nvidia only support 4096x4096 maximized for H264.
If there is anyways to walk around for this issue, plz let me know.
Examples and samples for those who develop software with FFmpeg.
