The h264_nvenc encoder only accepts nv12 input while most other encoders accept yuv420p. Semantically, yuv420p and nv12 are identical, an encoder that accepts both (and that runs single-threaded and produces deterministic output) would produce identical output if the „same“ nv12/yuv420p data is provided as input.

[FFmpeg-user] NV12 devices/players compatibility
Hi All, I know this is not strictly related to FFMPEG but please don’t insult me I normally transcode using ffmpeg with h264_nvenc, that produces a NV12 output, then I convert it in pix_fmt yuv420p before chunking in HLS/DASH But this conversion, when I do “all in hardware” transcoding in multiple profiles forces me to create quite complex filters. So I’d like to simplify the filters and just use NV12 end to end. Does anybody know realisticly how many devices/players out there can actually play a NV12 stream? Thanks in advance, Cheers Alex ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
