Ho alcuni MP4 che voglio caricare sul mio account flickr ma hanno una dimensione massima di 500mb poiché il mio è solo circa 550 stavo pianificando di dividerli a metà quindi caricarli, ma voglio assicurarmi che tutti i meta i dati sono inclusi ma non sembrano esserlo. Ho provato ognuna delle seguenti opzioni senza fortuna (alla fine di questo post ho le uscite originali e nuove di ffprobe):
ffmpeg -ss 00:00:00.00 -t 00:04:19.35 -i SANY0069.MP4 -acodec copy -vcodec copy -map_metadata 0:0 SANY0069A.MP4
ffmpeg -ss 00:00:00.00 -t 00:04:19.35 -i SANY0069.MP4 -acodec copy -vcodec copy -map_meta_data SANY0069.MP4:SANY0069A.MP4 SANY0069A.MP4
con questo ho prodotto manualmente i singoli meta tag che ho preso da questo comando
ffmpeg -i SANY0069A.MP4 -f ffmetadata meta.txt
ffmpeg -ss 00:00:00.00 -t 00:04:19.35 -i SANY0069.MP4 -acodec copy -vcodec copy -metadata major_brand="mp42" -metadata minor_version="1" -metadata compatible_brands="mp42avc1" -metadata creation_time="2012-09-29 09:05:50" -metadata comment="SANYO DIGITAL CAMERA CA9" -metadata comment-eng="SANYO DIGITAL CAMERA CA9" SANY0069A.MP4
usando l'output del precedente comando ho anche provato questo:
ffmpeg -ss 00:00:00.00 -t 00:04:19.35 -i SANY0069.MP4 -acodec copy -vcodec copy -f ffmetadata -i meta.txt SANY0069A.MP4
Output: output di esempio dal mio primo comando:
ffmpeg -ss 00:00:00.00 -t 00:04:19.35 -i SANY0069.MP4 -acodec copy -vcodec copy -map_metadata 0:0 SANY0069A.MP4

So che è incredibilmente lungo ma in realtà è una domanda abbastanza semplice. Ho pensato che sarebbe meglio fornire il maggior numero di dettagli possibile.
qualsiasi consiglio qui sarebbe fantastico,
Grazie
creation_time
(a meno che non sia omesso) e comment
sono impostati automaticamente. Il comportamento di creation_time
sembra variare tra 0.8.12
e l'attuale ffmpeg da Git; non sembra aggiungere / copiare questo a meno che non lo includa. Non ho fatto riferimento al codice, ma non copiare creation_time
durante la copia di stream può o non può essere considerato un bug a seconda di chi si chiede.
