Support de tous types de médias
10 avril 2011Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

ffmpeg ignores every framerate option, locking the result to 25 fps
1er août 2023, par Gouryffmpeg version 3.4.8-0ubuntu0.2 Copyright (c) 2000-2020 the FFmpeg developers


No matter what I do, ffmpeg just ignores everything and encodes it as if it's 25fps.

-framerate 60
does nothing

-t 60
does nothing

-r 60
makes it to interpolate frames

-r:v 60
does the same

-vf "fps=60"
does the same

-vframes <actual number="number" of="of" frames="frames"></actual>
makes it to end the encoding prematurely

Everything google shows seems to be outdated, including ffmpegs own documentation

FFMPEG muxed as a private data stream and may not be recognized upon reading
4 mars 2021, par JimmyI've came across a mkv with a codec of hevc , while trying to either convert it to m3u8 or mp4 I received this following message :


[mpegts @ 0x7f94de014600] Stream 1, codec flac, is muxed as a private data stream and may not be recognized upon reading.


Is there something wrong with my ffmpeg parameters ?


To m3u8 :
#1 :


ffmpeg -i aaa.mkv -s 1920x1080 -codec copy -bsf:v hevc_mp4toannexb -start_number 0 -hls_time 10 -segment_time 10 -hls_list_size 0 -f hls aaa.m3u8



#2 :


ffmpeg -i aaa.mkv -s 1920x1080 -codec copy -c:v libx264 -bsf:v hevc_mp4toannexb -start_number 0 -hls_time 10 -segment_time 10 -hls_list_size 0 -f hls aaa.m3u8



To mp4 :


#1 :


ffmpeg -i aaa.mkv -c copy ccc.mp4



#2 :


ffmpeg -y -i aaa.mkv -codec copy -strict -2 ccc.mp4

Transcoding with the GCP Transcoder API results in a time gap
3 mars 2021, par banyanI've been trying GCP's Transcoder API and having trouble with the time randomly becoming shorter than specified in certain cases.


The specific cases are as follows :


- 

- Specifying
startTimeOffset
andendTimeOffset
(cut off 2 seconds before and after the video) - fMP4 is used as container
- input video is mp4 with screen recording on iPad Pro








For example, if I don't specify
startTimeOffset
andendTimeOffset
, the time will not be shortened. Also, there is no problem when MPEG2-TS is specified for container. There may be a problem with the video itself, but I haven't found a clue how to set it up.

I'm not sure whether this is a problem with the Transcoder API or with me.

The following is a ffprobe of the resulting manifest file, which is 2 seconds shorter than specified. (expected :
00:02:47.00
, actual :00:02:45.00
