Transport Stream video encoded by VLC doesn't play on iPhone

[physicsguy]

For what it's worth, Mpeg Streamclip has similar problems with H.264+AAC encapsulated by VLC into MPEG2 TS. The video won't play.

from the apple forums:

"VLC does not work with our client (iPhone). It does not add the required H.264 Access Unit NAL between access units."

from viewtopic.php?f=4&t=63082&p=210918#p212377 :

In "Tools" -> "Preferences", select "All" in the Show settings box to display the advanced options. Then go to "Input/Codecs" -> "Video Codecs" -> "x264", and at the bottom of the list, tick the "Access unit delimiters" box. This will generate the NAL units required by the segmenter.

The segmenter doesn't give errors any more! but the video won't play on the iPhone, as before This is my command line:

Code: Select all

"/Applications/VLC.app/Contents/MacOS/VLC" -vvv -I dummy "/Users/ajln/Desktop/batman.mp4" --sout='#transcode{vcodec=h264,venc=x264{no-cabac,level=3.0,subme=5,trellis=1,merange=16,min-keyint=25,scenecut=40,ipratio=0.71,ratetol=20k,vbv-maxrate=96k,vbv-bufsize=96k,qcomp=0.6,qpmin=10,qpmax=51,qpstep=4,keyint=30,ref=1,deblock=0:0,aud},scale=1,acodec=mp4a,ab=128,samplerate=48000,channels=2,width=320,height=240}:duplicate{dst=std{access=udp,mux=ts,dst=127.0.0.1:1234}}'

Hi jaimed.
Here is my workaround.

VLC command line:

Code: Select all

/Applications/VLC.app/Contents/MacOS/VLC --intf=dummy --sout=#transcode{width=320,height=240,fps=25,vcodec=h264,vb=256,venc=x264{aud,profile=baseline,level=30,keyint=30,bframes=0,ref=1,nocabac},acodec=mp4a,ab=56}:duplicate{dst=std{access=udp,mux=ts,dst=127.0.0.1:54321}} http://streaming-server-address/

mediastreamsegmenter command line:

Code: Select all

mediastreamsegmenter -b http://web-server/stream-dir -f /path/to/stream-dir -t 10 -s 4 -D 127.0.0.1:54321

and HTML:

Code: Select all

<video width="320" height="240"> <source src="./prog_index.m3u8" /> </video>

I hope this helps you

Here is more simple way.
Instead of using UDP stream, use stdout/stdin.

Code: Select all

/Applications/VLC.app/Contents/MacOS/VLC --intf=dummy --sout=#transcode{width=320,height=240,fps=25,vcodec=h264,vb=256,venc=x264{aud,profile=baseline,level=30,keyint=30,bframes=0,ref=1,nocabac},acodec=mp4a,ab=56}:duplicate{dst=std{access=file,mux=ts,dst=-}} http://streaming-server-address/ | mediastreamsegmenter -b http://web-server/stream-dir -f /path/to/stream-dir -t 10 -s 4 -D

You should consider using InStream Mobile app to play natively UDP MPEG Transport Stream with H.264 video / AAC-LC audio on iOS

Pretty simple to use and it works well over both unicast & multicast-capable wireless networks
