[FFmpeg-devel] 回复: 回复: [PATCH] libavformat/movenc: add support for HEVC in .3gp

[Sun Zhenliang]

I agree that it'd be fine to add those two tags of hevc there.

Thanks for your review.

Regards,

I think these documentations says we can store hevc in 3gp files.

The document seems to be available at:
https://www.etsi.org/deliver/etsi_ts/126200_126299/126244/16.01.00_60/ts_126244v160100p.pdf

And seems to just refer to the "H.265 (HEVC) file format", which is
effectively what's under 14496-15 now.

Thus I would say that it'd be fine to just add both 'hev1' and 'hvc1'
there, as both are specifically mentioned at multiple points in the
specification

Best regards,
Jan
