Grab (all) audio samples with ffmpeg, C/C++ [closed]
28 août 2020, par nji9For further analysis I need to access/ collect all samples of
audio files with ffmpeg.
There are lot of code examples around, but all of them are either out-of-date
(using deprecated or non-existing ffmpeg API),
or are buggy (multiple frames in packets etc), or are incomplete...


So, could some of the profs please present a simple working code ?


In : Just filename, Out : Just error code, Within : Determine properties and access audio samples.


Would probably be of great help not only for me ;-)


Thankyou in advance.

Read packets from swf using ffmpeg ?
29 mars 2012, par parvezThe GetNextVideoPacket() method in ffmpeg allows us to recieve next video packet from the media source.
ex- packet = source->GetNextVideoPacket() ;
I would like to know if this works on shockwave file(swf) as well. Thus in above case can source be a swf file. If not then is there any other functionality which allows us to read swf in packets ?
Thanks in advance.

FFMPEG - Audio going out of sync when using Tempo And setPTS
5 février 2016, par loveforfire33Very new to ffmpeg and have been trying all day to get this working. I am trying to slow down a video and its audio at the same time (mp4). I have tried doing the audio and video separately with a very similar version of the code below but still get the same effect.
The audio slowly goes out of sync with the video after roughly 30 seconds(audio goes faster). Any advice would be appreciated.
-i "INPUT" -filter_complex "[0:v]setpts=1.1*PTS[v] ;[0:a]atempo=0.9[a]" -map "[v]"" -map "[a]" "OUTPUT"
Thanks in advance
