ffmpeg / video processing : make video repeat itself without duplicating content ?
31 mars 2022, par RocketNutsSuppose I have a video file that is 20 MB in size and lasts 30 seconds.


I want to create a new video file that basically consists of the existing video, repeated 10 times. So the new video should last 300 seconds (5 minutes) and contain the same content every 30 seconds.


I could of course append this video to itself 10 times, resulting in a file of approximately 200 MB. But this seems very redundant, since obviously the same content is in there tenfold. I was hoping for a somewhat more intelligent approach, where the same 30 seconds of video is somehow 'referenced' 10 times over.


Do common encoders or container formats (say h.264 in a .mp4 or .mkv container) support this ? And by any chance is there a way to pull this off with
ffmpeg
?

Can ffmpeg write metadata encoder when transcoding alac/flac to aac audio file ?
11 juin 2022, par David II have a collection of alac and flac files from Bandcamp and an ffmpeg instance compiled with libfdk_aac https://trac.ffmpeg.org/wiki/CompilationGuide/Centos#libfdk_aac and am trying to convert these to lossy audio aac files for non-critical listening.


With
ffmpeg -i Liholesie\ -\ Shamanic\ Twilight\ -\ 09\ Gray\ Wings.m4a -c:a libfdk_aac -vbr 4 -c:v copy 09_Gray_wings_vbr4.m4a
an expected aac .m4a audio file is produced, album art included, works well. There's one slight detail missing :

During the ffmpeg conversion process ffmpeg says :


Output #0, ipod, to '09_Gray_wings_vbr4.m4a':
 Metadata:
 major_brand : M4A 
 minor_version : 512
 compatible_brands: M4A isomiso2
 title : Gray Wings
 artist : Liholesie
 album_artist : Liholesie
 album : Shamanic Twilight
 comment : Visit https://liholesie.bandcamp.com
 date : 2021
 track : 9
 encoder : Lavf59.24.100
 Stream #0:0: Video: mjpeg (Baseline), yuvj444p(pc, bt470bg/unknown/unknown), 700x700 [SAR 72:72 DAR 1:1], q=2-31, 90k tbr, 90k tbn (attached pic)
 Stream #0:1(und): Audio: aac (mp4a / 0x6134706D), 44100 Hz, stereo, s16 (default)
 Metadata:
 handler_name : SoundHandler
 vendor_id : [0][0][0][0]
 encoder : Lavc59.33.100 libfdk_aac 
..





and the file produced looks like that when ffprobed except that the Metadata : encoder field is missing :


Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '09_Gray_wings_vbr4.m4a':
 Metadata:

 Stream #0:0[0x2](und): Audio: aac (LC) (mp4a / 0x6134706D), 44100 Hz, stereo, fltp, 152 kb/s (default)

Is there a way to write the encoder field in the Metadata section when transcoding (or is "encoder" not supported for aac m4a ? That would be weird since ffmpeg says what it says when specifying output during transcoding) .


Any hints on how to write a self-defined text to said tag during transcoding are also welcome.
