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

[Sun Zhenliang]

1) 3GPP TS 26.244 V16.1.0 (2020-09)  and ISO/IEC 14496-15: "Information technology – Coding of audio-visual objects – Part 15: Carriage of NAL unit structured video in the ISO base media file format"   states HEVC's sample entry in 3GPP file format. I think these documentations says we can store hevc in 3gp files.

2) I just found that I could encode hevc into 3gp files by adding tags to 3GP tag list. By just adding one line, ffmpeg could make 3gp file with hevc and ffplay can also play it correctly. That's enough for me.  Because I don't set parameters very much, I didn't find any parameter restrictions.

SunZhenliang

Ps: First contribution of open source project and first use of mailing lists.😊

1) Is there official documentation for this support?
2) Any constraints on codec parameters?
