An updated version of PR #1027
That previous PR was done using 2021 code, and there were many changes
in the codebase from there, so a rebase was needed and also some minor
tweak here and there. But it's the same code, just reimplemented on a
newer codebase.
If you want to take a look at this in action, after building shaka
packager with this PR's code included, try this commands in 3 different
simultaneous bash sessions:
1. Video UDP input: `ffmpeg -f lavfi -re -i
"testsrc=s=320x240:r=30,format=yuv420p" -c:v h264 -sc_threshold 0 -g 30
-keyint_min 30 -r 30 -a53cc 1 -b:v 150k -preset ultrafast -r 30 -f
mpegts "udp://127.0.0.1:10000?pkt_size=1316"`
2. WebVTT UDP input: `for sec in $(seq 0 9999) ; do printf
"%02d:%02d.000 --> %02d:%02d.000\ntest second ${sec}\n\n" "$(( ${sec} /
60 ))" "$(( ${sec} % 60 ))" "$(( (${sec} + 1) / 60 ))" "$(( (${sec} + 1)
% 60 ))" ; sleep 1 ; done > /dev/udp/127.0.0.1/12345`
3. shaka packager command line: `timeout 60
path/to/build/packager/packager
'in=udp://127.0.0.1:10000?timeout=8000000,stream_selector=0,init_segment=240_init.m4s,segment_template=240_$Number%09d$.m4s,bandwidth=150000'
'in=udp://127.0.0.1:12345?timeout=8000000,stream_selector=0,input_format=webvtt,format=webvtt+mp4,init_segment=text_init.m4s,segment_template=text_$Number%09d$.m4s,language=eng,dash_roles=subtitle'
--mpd_output ./manifest.mpd --segment_duration 3.2
--suggested_presentation_delay 3.2 --min_buffer_time 3.2
--minimum_update_period 3.2 --time_shift_buffer_depth 60
--preserved_segments_outside_live_window 1 --default_language=eng
--dump_stream_info 2>&1`
Note the added `input_format=webvtt` to the shaka packager command's
second selector. That's new from this PR. If you don't use that, shaka's
format autodetection will not detect the webvtt format from the input,
as explained in
https://github.com/shaka-project/shaka-packager/issues/685#issuecomment-1029407191.
Try the command without it if you want to.

This work was done over ~80 individual commits in the `cmake` branch,
which are now being merged back into `main`. As a roll-up commit, it is
too big to be reviewable, but each change was reviewed individually in
context of the `cmake` branch. After this, the `cmake` branch will be
renamed `cmake-porting-history` and preserved.

In addition to the MediaSample handling of the MediaParser, this now
adds callbacks for TextSample. This allows reading text streams from
the media files.

Created a handler called OriginHandler that can be used by the Job class
(previously called RemuxJob). Origin handlers represent the start (or
origin) of a pipeline (chain of handlers).

- Also fix the misleading error if an invalid input is provided
The command line app now correctly reports that the file is not
found instead of stream not available.
