Not even, It’s per sample, iirc, but > I ask because I'm seeing some truly abnormal results with hevc_nvenc when > the -tag:v hvc1 option is passed where the CPU load spikes up significantly. hvc1 is the one with codec params in the sample description box, so I guess it’s parsing (basically decoding, as I’ve been told) the stream to copy it to the header. (Or box, I should say, rather. And I’m not sure if it also deletes them after, but I’m pretty sure there’s a separate bsf that does that though.) _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user
