To assemble episodes of 'The Solitary Eater' by the following steps.

Let
[$EPISODE] = [S1E02] [$FILE] = [./episodes/$EPISODE.txt] [$PREFIX] = [https://proxy-01.eightytwovideoprogood.xyz/cdn01/hls/61566024dd75dfb79e39833ai] [$NNNN] = [0000] [$PNG] = [7492933fc80e3a3469ce592303348e30.png] [$URL] = [${PREFIX}/${PNG}] [$MP4] = [${EPISODE}_${NNNN}.mp4
Here
  1. [$EPISODE] is the standard name of an episode.
  2. [$FILE] is an episode file which has embeded within it an ordered list of URLS to PNG files needed to assemble the episod.e
  3. [$PREFIX] is a common prefix to each URL in the list
  4. [$NNNN] is an ordinal denoting which URL in the list is being considered. (Ordinals are 4 digit, zero based).
  5. [$PNG] is the name of the PNG file corresponding to the ordinal
  6. [$MP4] is the [$PNG] file renamed.
NOTWITHSTANDING THIS:
The prefix alternates between the following:
[https://proxy-1.{stuff}] [https://proxy-2.{stuff}]

but this does not affect the assembly order.

We generate a script that will parse all episode files, wget all it's PNG files, and rename them as MP4 files in a way that indicates their order of assembly.

What is left to implement are the steps:

EXTRACT MP4

mkvmerge --ui-language en --output ^"$$OUTPUT-1$$.mp4^" --language 0:und --compression 0:none --language 1:und --compression 1:none ^"^(^" ^"$$INPUT-1$$.mp4^" ^"^)^" --track-order 0:0,0:1

CONVERT TO TS

ffmpeg -i $$INPUT-2$$.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts $$OUTPUT-2$$.ts

MERGE TO MP4

ffmpeg -i "concat:$$001$$.ts|$$002$$.ts|$$003$$.ts" -c copy $$DONE-1$$.mp4
