TV audio extracted using ffmeg does not work in iOS (but it works in the simulator)
26 janvier 2014, par GenarI can process a TV signal (well I have a .ts video which comes from a TV channel), using ffmpeg but the audio cannot be understood in an iPhone/iPad. The most strange is that the audio (and video) works properly in the simulator (and also in an Android real device, but this is another point), but in a real iPhone/iPad device the video is OK but the audio sounds like a metallic box and nothing can be understood.
I have created the ffmpeg libraries for iOS (I have tried the version 2.0.2 and also the version 2.1.3) using the information provided in the following link :
Installing ffmpeg ios libraries armv7, armv7s, i386 and universal on Mac with 10.8
The aforementioned link explains how to create the ffmpeg include folders and the universal libraries which I have included into my project (the libraries created are : libavcodec.a, libavdevice.a, libavfilter.a, libavformat.a, libavresample.a, libavutil.a, libswresample.a and libswscale.a).
The sampling frequency used is 48000.
The audio got from ffmpeg is then stored into a buffer and then "inserted" using OpenAL ; but, from the same TV content (the same .ts video file) the audio data which is generated from ffmpeg in an iPhone/iPad is totally different from the audio data generated from ffmpeg in the simulator (which can reproduce both the audio and video perfectly).
Thanks in advance,

concatenate mp4 videos with ffmpeg concat demuxer in android
6 mai 2016, par Ara BadalyanI want to concatenate mp4 videos with ffmpeg, the problem is when I want to merge videos taken with Iphone and Android it throws problem
" Non-monotonous DTS in output stream 0:1 ; previous : 150528, current : 139268 ; changing to 150529. This may result in incorrect timestamps in the output file."
This is my code
merge.txt
file 'iphone.mp4'
file 'android.mp4'ffmpeg command
ffmpeg -f concat -i marge.txt -c copy -y merge.mp4If I can’t merge this videos how can i make them with same parameters (frame rate, bitrate...) and merge them ?
P.S I use ffmpeg version 2.4.2 , because I can’t find android ffmpeg library higher then 2.4.2.

Stream specifier ':a' in filtergraph description [0:v][0:a][1:v][1:a]concat=a=1:n=2:v=1[s0][s1] matches no streams
6 septembre 2022, par MashI am using ffmpeg-python and I am trying to make a code that gets all the clips from a folder, converts all of them to the same format then merge all of them with their audio to one final video file.


Here is how the python script looks like


import os
import ffmpeg

dir = "./clips/"

# Reshape video
for f in os.listdir(dir):
 (
 ffmpeg
 .input(os.path.join(dir, f))
 .filter("scale", size="hd1080", force_original_aspect_ratio="increase")
 .filter('fps', fps=60, round='up')
 .output(str(os.path.join(dir, f))[:-4] + "_reshaped.mp4")
 .run()
 )

# Select reshaped video
files = []

for f in os.listdir(dir):
 if "_reshaped.mp4" in str(os.path.join(dir, f)):
 files.append(ffmpeg.input(str(os.path.join(dir, f))))

# eparate video and audio, then flat the array
video_and_audios_files = [item for sublist in map(lambda f: [f.video, f.audio], files) for item in sublist]

# concat all
joined = (
 ffmpeg
 .concat(*video_and_audios_files, v=1, a=1)
 .node
)

# merge video and audio
(
 ffmpeg
 .output(joined[0], joined[1], "./out.mp4")
 .run()
)



Now here is my output, this is the output of the part of the code that merges every clip into one (aka the merge video and audio section of the code)
