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Everything google shows seems to be outdated, including ffmpegs own documentation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