Ran a pull on my local windows machine. Verified that the segments in red are being downloaded but clearly FFMPEG is failing to concat it all together, claiming packet corruption? I have not investigated the segments in question. Perhaps FFMPEG is mistaking a lack of an audio track as corruption when all the other segments have audio tracks?

Nevermind, it appears that the audio track does, in fact, exist and its just silent the whole time. Not sure why mpegts has issue opening the video when Premiere, VLC, and even Windows Media Player can open and view the video just fine. Definitely out of the scope of VodBot's code, but maybe some special flags need to be added for FFMPEG to work with silent audio?

VodBot/vodbot/itd/download.py

Lines 83 to 87 in 3c8b3fa

cmd = [
"ffmpeg", "-i", str(playlist_path),
"-c", "copy", path, "-y",
"-stats", "-loglevel", LOG_LEVEL
]

Here is VodBot's command that opens FFMPEG to concat all the segments together with the help of the m3u8 file (which is the playlist_path in this case). Nothing explicitly declares that FFMPEG is opening an m3u8 file so it's figuring out what it needs to use (mpegts, in this case) on its own. The path variable is just the output file path, and everything after that is just to make FFMPEG output lightweight info.

I removed the set of commands from the cmd to show full output. The issue is now clear as day, the muted sections of the VOD are meant to have a suffix of "-muted", which they don't get when downloaded! The culprit is in here:

VodBot/vodbot/itd/worker.py

Line 123 in 3c8b3fa

targets = [str(target_dir / f"{k}.ts") for k, _ in enumerate(vod_paths)]

Here, the targets for downloads are generated, but they are incorrectly labeled as unmuted when their paths are generated. Instead they rely on a loop generating their indices, rather than their actual paths. This should be an easy-enough fix, simply changing from using indices to actually manipulating the URL string to give the appropriate output file name.

Minor reminder for myself tomorrow morning to open issues to allow a CLI toggle to switch off temp folder removal and enable FFMPEG full output.

NotQuiteApex avatar NotQuiteApex commented on August 22, 2024

This should be fixed now, however I was not able to fully test the changes before the VOD got unmuted by Twitch from the counterclaim Alchana submitted this morning. Will keep an eye on things for the next few months.
