Incomplete files not playable, like before #61

Open teafusion opened 1 year ago

teafusion commented 1 year ago

Just downloaded the 20230725 release and the incomplete videos refuse to playback. In previous installations I've used the incomplete videos were mostly playable up to where they were broken, at least I think so.

The download itself was constant speed, not very fast, but constant, unlike previous installations, where the speed fluctuated and spiraled down, but the old problem of download breaking up continues it seems, unfortunately.

In this version, by default, the video is downloaded first, then audio. An unfinished video (file with *.video extension) can be viewed after it has been processed with ffmpeg:

ffmpeg -i input.video -c copy output.mkv

It's very fast, no reencoding

But, if the *.video file has a small size and contains a text (https urls), then this is a yrewind's bug which appears on some streams. I've already fixed it, plan to release new version soon.

I have a speed of ~15 Mbps, regardless of the provider. But no one bothers to download several parts at the same time ) On the main page there is a convenient bat file for this

Ookla speedtest shows that I should have sub 12Mbps, but ee.yrewind does ~0,350 Mbps quite constant. Wonder what might cause the throttle? Also I couldn't get the multipart .bat work, but I can start separate .bat files running at the same time and at least two at once gives the same ~0,350 Mbps. I lack skill in troubleshooting scripts like the multi part .bat, one thing I imagine could be that I use only portable Chrome, if it counts. I don't know if the output path might make difference, I tried many formatting alternatives. When I start the multi part .bat, it seems to run something in the background for a while, but then stops and quits all three parts that I had for test, no folders or files were created in the process.

Tried to analyze my tweaks on the example .bat and started to wonder it these lines were ok:

set O="D:\Captures\*start*_*title*.mkv"

start yrewind -F=%F% -B=%B% -O=%O% -U=%U% -S=20230731:1300 -D=240

Otherwise my script follows pretty accurately the example .bat formula.
