How to open a HEIF (.heic) image ?
14 décembre 2022, par Jean-Milost ReymondFor a c++ project, I need to open and show a HEIF (.heic) image. What I know (if I'm right) is that the HEIF images are based on the ffmpeg standard, and requires a H265 codec to be read.



I found several open-source H265 codecs :



- 

- OpenHEVC (https://github.com/OpenHEVC/openHEVC)
- x265 (https://bitbucket.org/multicoreware/x265/downloads/)
- libde265 (https://github.com/strukturag/libde265)









I can open and show H265 encoded video files with each of them, but I'm unable to simply open, show or convert a .heic image. All of them return an error, or just do nothing.



To be honest I'm a little puzzled, because the HEIF standard seem to be a well kept secret. I'm unable to find a relevant info that could allow me to walk to a solution. Those I found are just tricks and workarounds, like e.g. forcing the device (I'm speaking here about the Apple iPhone using the new iOS11) to generate a jpg image instead of a heic, or using a third party application like dr.fone. Of course these solutions are irrelevant for me.



So, somebody can tell me which codec I should use with a .heif image, and how I can use it to open it ? Or are there open source libraries or examples that allow to manipulate this type of image file ? Somebody can point me to the good direction ?

Prevent libavformat (FFmpeg) from adding "ENCODER" tag to output / stripping tags
1er mars 2014, par Wyatt8740I made a bash script that transfers audio or video metadata from one file to another, regardless of media container format, via FFMpeg. My problem is that FFMpeg consistently adds a 'ENCODER' tag.
Example :
Before running through FFMpeg :
File : track01.cdda.flac
Metadata:
ALBUM : Wish You Were Here
ARTIST : Pink Floyd
COPYRIGHT : 1975 Harvest Records
DATE : 1975
GENRE : Experimental Rock
TITLE : Shine On You Crazy Diamond
track : 1After running through FFMpeg :
File : track01-iphone-alac.m4a
Metadata:
ALBUM=Wish You Were Here
ARTIST=Pink Floyd
COPYRIGHT=1975 Harvest Records
DATE=1975
GENRE=Experimental Rock
TITLE=Shine On You Crazy Diamond
track=1
ENCODER=Lavf55.12.100So really, I want to either force FFMpeg to not add the 'ENCODER' tag, or I want to strip that tag off afterwards. Is there a way to do this ? I really don't want to spend hours trying to compile FFMpeg again on my Pentium 4 HT - the only working computer I have at the moment. I'd prefer not to have to use another program unless it's related enough to FFMpeg or MPlayer/Mencoder that I won't have to install anything new if I have those installed.
