  • Is 32-bit-only app running on iPhone 6 slower then on iPhone 5 ?

    22 avril 2015, par ChihHao

    I have an app that is build with very old ffmpeg library(Ver. 0.10.4). I found that when iPhone 5 decoding the H.264 stream with VGA resolution, the used percentage of CPU is about 10% lower then iPhone 6’s.

    The ffmpeg lib file only support arm V7 and arm V7s architecture. So I think that the function provided by ffmpeg will run faster or more efficency on the machine with the supported architecture. Is that right ?

  • Recorded & uploaded video from iphone device won't play in iphone

    11 juin 2019, par Sohil Chamadia

    I am facing an issue regarding :

    Recording video from iphone and uploading that video on my application(Develop in Wordpress Framework) then the video uploaded won’t play in iphone devices.

    This issue occurs only when I "Record video from iphone and then uploading that video into the application".If I upload existing video from iphone device then video will be played and it’s working fine. So please help to resolve this issue.I have used "FFmpeg library" to reduce the size of video.

    Below is the code which i have used to play video :

    <video preload="auto" width="320" height="240" controls=""><source src="abc.mp4" type="video/mp4">Your browser does not support the video tag.</source></video>

    When i click on video to play it then video is not play and cross sign is shown over the play button.Below i have attached screenshot of it :

  • Mix Audio tracks with offset in SOX

    4 août 2012, par Laramie

    From ASP.Net, I am using FFMPEG to convert flv files on a Flash Media Server to wavs that I need to mix into a single MP3 file. I originally attempted this entirely with FFMPEG but eventually gave up on the mixing step because I don't believe it it possible to combine audio only tracks into a single result file. I would love to be wrong.

    I am now using FFMPEG to access the FLV files and extract the audio track to wav so that SOX can mix them. The problem is that I must offset one of the audio tracks by a few seconds so that they are synchronized. Each file is one half of a conversation between a student and a teacher. For example teacher.wav might need to begin 3.3 seconds after student.wav. I can only figure out how to mix the files with SOX where both tracks begin at the same time.

    My best attempt at this point is :

    ffmpeg -y -i rtmp://server/appName/instance/student.flv -ac 1 student.wav 
    
ffmpeg -y -i rtmp://server/appName/instance/teacher.flv -ac 1 teacher.wav 
    

    
sox -m student.wav teacher.wav combined.mp3 splice 3.3

    These tools (FFMEG/SoX) were chosen based on my best research, but are not required. Any working solution would allow an ASP.Net service to input the two FMS flvs and create a combined MP3 using open-source or free tools.

    EDIT :
    I was able to offset the files using the delay switch in SOX.

    sox -M student.wav teacher.wav combined.mp3 delay 2.8

    I'm leaving the question open in case someone has a better approach than the combined FFMPEG/SOX solution.
