HLS-29 Write parent pid into failfile name

Stops previous failures breaking future jobs if files don't get tidied for some reason

HLS-29 Add PoC code for catching ffmpeg failures

If ffmpeg exits with a non-zero exit code, a failure file is written to and the mux is aborted. HLS-Stream-Creator will exit with status code 1 in this event

No-op. Just tidying up the usage information a bit as it was bugging me

HLS-24 Allow audio track to be ignored with the `-n` commandline argument

This forces `-an` to be passed to `ffmpeg`.

It's not generally required, as missing audio tracks will be handled by default, but this allows the user to address inputs where `ffmpeg` reports the Audio type as `none`:

Stream #0:0: Video: flv1, 1 reference frame, yuv420p, 1280x720, 199 kb/s, 8.33 tbr, 1k tbn, 1k tbc
Stream #0:1: Audio: none, 0 channels

This test stream was the result of a webcam being published into an RTMP relay with FFMPEG and then pulled back out the other side.

Usage and README were missing some options

Add setup steps on Mac OS X, based on having run through them in HLS-33

Fix variable name for HLS-33

HLS-33 Macs appear not to like the ternary operator (see #30)

Swapping to a less concise syntax. Either I've missed something more fundamental, or this should work

HLS-33 Update README

HLS-33

Not convinced I could have screwed that last commit up much more.

* Reverse the logic (override the var if the command completes successfully)
* Insert missing semicolons

In my defence, the commit *was* done to deploy onto my test system

HLS-33 Test for presence of ggrep and gsed and use those if they exist

This is due to a change in `brew` that means you can no longer use `--with-default-names`, the replacement method (adjusting PATH in bashrc) seems to have inconsistent results.

Yeah, I totally forgot to commit this fix for HLS-27 :(

Adjusts the path passed into {{appendVariantPlaylistentry}} so that it doesn't include the resolution (as the manifest filenames currently don't)

Linear support for HLS-27 has now been tested, so update README to note the resolution functionality.

Implement ability to specify resolution with bitrates. See HLS-27

This is just a first pass at this, and I fully expect it to break in a variety of weird and wonderful ways.

There's also some reliance on globals that I don't like (see comments in file), so that's still in need of tidying up. We should probably also think about testing that none of the given resolutions are higher than that of the source.

But, you can now pass a resolution in as part of the bitrate string: {{bitrate-widthxheight}}

As an example, ran the following test encode
{noformat}$ ./HLS-Stream-Creator.sh -i testvid.mp4 -b 2744,1000-1280x720 -s 10
{noformat}
The original is 1080p at 2744k so that should give us a 1080p rendition as well as a 720p.

Master playlist is generated correctly
{noformat}$ cat testvid_master.m3u8
testvid_2744.m3u8
testvid_1000-1280x720.m3u8
{noformat}

Segments report approximately the right bitrate (used vbr to speed up the test), and also the correct resolution

Make OUTPUT_DIRECTORY play nicely with -S & -o

The command:
`./segment.sh -i video.mov -s 4 -b 512 -t video -p video -S partials -o streams` would fail without this fix, as it would try to access streamspartials (notice the missing directory-separator).

and you would have to append the slash in your config and make the command look like this:
`./segment.sh -i video.mov -s 4 -b 512 -t video -p video -S partials -o streams/`

This fixes the issue, and you can now omit the last slash in the -o flag.

Switch variable name to something that isn't a command, as it was bugging me. HLS-21

Updated README to note the issue with aac being marked as experimental in some ffmpeg builds. See HLS-23

Update README to contain more information on encrypted streams (HLS-20)

Add some status output

Adjust encryption loop to ensure the IV is based on the segment number rather than a counter. HLS-22

Updated README to reference encryption. See HLS-20

Adjust manifest filename in encryption. See HLS-20 and #15

The encrypt function assumed a single bitrate stream (not generated using a -b argument), have changed the way manifest files are located when we write key information into them.

Could be improved - we'll currently write into the master playlist too, which is harmless but unnecessary. Just didn't seem worth putting a check in to stop it

Fix issue with iterating over and encrypting segments when relative output dir is used. See HLS-20

Should still be considered a partial fix - need to correct a manifest filename

Partial fix for #15 and HLS-20

This commit adjusts the code path when bitrates are specified on the command line. to ensure that encrypt is called (wasn't before)

A second fix is needed to the manifest rewrite as it is currently looking for the wrong file (unless bitrates haven't been specified)
