[Live-devel] help with streaming a .ts file

[Jason Reeves]

The given openRTSP command generates a folder full of files with the .mp4
extension.  We have to rename them to .m4e in order for live555MediaServer
to stream them.  :)

Here are the properties of the files as reported by avprobe:

$ avprobe output-00000-00060.mp4
avprobe version 11.7, Copyright (c) 2007-2016 the Libav developers

      encoder         : MPEG-4 Video
# avprobe output

My first attempt at converting this to a TS looked like this:

ffmpeg -i output-00000-00060.mp4 -f mpegts -vcodec copy -acodec copy
output.ts

That didn't work.  I managed to get the sample "bipbop" TS from the live555
website to work, so I tried to make my TS look as much like that as
possible.  I know live555MediaServer is finicky about what it will and
won't stream, so I assumed it might have something to do with the encoding
of the stream.  The "bipbop" clip contained an h264 video stream, so I
tried to create a TS with an h264 stream from my .mp4 file:

ffmpeg -i output-00000-00060.mp4 -vcodec libx264 output.ts

That also didn't work.  I also used the MPEG2TransportStreamIndexer program
to generate the .tsx files in both cases.  No luck.

In both cases, I am able to play the resulting TS file with VLC.
