Ios – How to convert (re-wrap) Transport Stream to MPEG-4 container in iOS app

ffmpegiosstreaming

I have a live stream in .ts format, containing AAC audio and H.264 video. I want to play it on iOS devices. I tried to use a movie player based on FFmpeg to decode and play video, but the audio was lagging.

Can I rewrap this Transport Stream to an MPEG-4 container to play on iOS devices – without converting it server-side?

The server returns me a URL of the .ts live stream and my goal is to play this stream on iOS devices without an .m3u8 playlist because I can't get it from the server.

To just re-mux without transcoding you can use: ffmpeg -i input.ts -acodec copy -vcodec copy out.mp4

Go to Targets in Xcode.
Build Settings on your project's target (your current development name).
Search for Product Name under Packaging. Change its value to what you want your new project name to be.

Transcode and segment with ffmpeg

Absolutely - you can use -f segment to chop video into pieces and serve it to iOS devices. ffmpeg will create segment files .ts and you can serve those with any web server.

Working example (with disabled sound) - ffmpeg version N-39494-g41a097a:

./ffmpeg -v 9 -loglevel 99 -re -i sourcefile.avi -an \
-c:v libx264 -b:v 128k -vpre ipod320 \ 
-flags -global_header -map 0 -f segment -segment_time 4 \
-segment_list test.m3u8 -segment_format mpegts stream%05d.ts

Tips:

make sure you compile ffmpeg from most recent git repository
compile with libx264 codec
-map 0 is needed

How I compiled FFMPEG - with extra rtmp support to get feeds from flash-media-server

export PKG_CONFIG_PATH="/usr/lib/pkgconfig/:../rtmpdump-2.3/librtmp"    

./configure --enable-librtmp --enable-libx264 \
--libdir='../x264/:/usr/local/lib:../rtmpdump-2.3' \
--enable-gpl --enable-pthreads --enable-libvpx \
--disable-ffplay --disable-ffserver --disable-shared --enable-debug
