ffmpeg convert mp4 video for phones
23 avril 2015, par Ar MegatoxI need to make a video which will play on iPhone and Android but the problem is when I click play on the phone it needs minimum 7 seconds to start.
So maybe I need to fix something in this code to make the video play on phones (maybe another format is needed) :
ffmpeg -i VIDEO -c:v libx264 -s 640x480 -strict experimental -c:a aac VIDEO.MP4
There must be something to make the video play faster without a delay on start.
I tried a
FLV
file and it worked fine on Android but the iPhone can’t play it. -
How to convert 4:3 video to 16:9 without stretching the original in ffmpeg
5 novembre 2016, par carvilI would like to convert some 4:3 videos that I took on an iPhone to 16:9, by adding black bars to both sides instead of stretching the video.
I tried something like this without success :
ffmpeg -y -i input.mov -aspect 1.7777777777777777 -s 640x360 output.mp4
Even though the output has the correct size, the video is stretched, which is not what I want.
How can I keep the proportion between the width and height of the original video, and add extra black bars to both sides to avoid stretching ?
This would be similar to how YouTube does it when uploading a video from an iPhone directly to YouTube.
Thanks !

FFMPEG RTP Microphone Audio Stream Won't Work Over 4G/LTE
11 juillet 2021, par Andrew SmithI am trying to RTP stream the Mic input of my USB soundcard over 4G to an iphone running VLC, the phone is on the Three UK mobile network. I cannot get any audio at all but it works with no problem if I route it via a VPN, my ffmpeg command is :-


ffmpeg -f dshow -i audio="Microphone (C-Media USB Headphone Set )" -c:a libmp3lame -f rtp rtp://xxx.xxx.xxx.xxx:1234


I am streaming to the ip of the phone as shown by whatsmyip in a browser, then trying to play the stream on the iphone using rtp ://@:1234


If I switch on my VPN and change the ffmpeg stream-to ip address to my 10.0.0.xxx ip then it works just fine.


Something seems to be blocking RTP when not using the VPN, could it be the 4G network blocking it ?
