Saved media with slide in gallery not showing.

fozters commented 5 years ago

Slide version:5.9-alpha2 Android version:9 Oneplus 6, f-droid slide, for some reason when I save image, gif, mp4 with slide for reddit it doesn't show up in phones gallery until I reboot phone.

Just like the media library would not get refreshed somehow. Not having similar issues with any other app. Is this android 9 problem?

Great app otherwise and which I chose to replace vanilla reddit app. This one thing just buggers me. Probably will go pro later on.

Sounds like a OnePlus-specific issue to me. Media that I save from slide shows up immediately in my gallery on both android 8.1 and 9.

Thanks for info. I tried to re-install app from fdroid, install the playstore version and they are acting the same.

Weird is as when you are at /gif saving some gif or other media file if you select "save gif" and "save mp4" both from drop down menu, the other one sometimes is visible in gallery without reboot.

If you have used both to download & reboot you have 2 same files. If you use the dowload icon you have to reboot to see media file in gallery.

I'm using /storage/emulated/0/pictures/reddit as download folder. Runnin oxygen os 9.0.2 version.

Is there any other way I can help to diagnose the problem? Is there anything else I can try to fix the problem, like some settings or something?

Just to add it might be op6 gallery problem indeed. Weird that I've only seen it non functioning properly with slide gifs. Here is something similar https://forums.oneplus.com/threads/gallery-not-working-properly.861282/ So I installed other gallery app as suggested and I can see the gifs immidiatly. My bad I just didn't think gallery app would be replaceable app..

I also face this issue. Since I have been trying to circumvent it for a couple years and it has the Needs Reproduction label, I will attempt to add a few notes here and hopefully get it fixed.

Disclaimer: I am no expert in video encoding, etc.

Let's suppose I want to download this video outside Reddit. By digging on the code or using external applications, I am able to find 2 sources: DASH and HLS. Apparently they are both streaming URLs, but DASH doesn't have audio. The audio track apparently loads separately. From now on, whenever I talk about DASH, you should imply it has no audio.

Downloading

Windows + Chromium -> DASH opens and I am able to save it as a mp4 file. HLS attempts to open an external application (in my case, it opens mpv and works).
Android + Chromium -> DASH: same as above. HLS simply downloads a file named HLSPlaylist.m3u8.
Slide -> it downloads the video and saves it as mp4
Third-Party Websites -> they usually download the video and save it as mp4. I used a few common websites for downloading Reddit videos that can be found on Google. They often have 2 links: with or without audio.
ffmpeg -> I just ran ffmpeg -i https://v.redd.it/qakawehf50s41/HLSPlaylist.m3u8 test.mp4 to download the HLS file.

Now this is where things get interesting...

Sharing, Embeding URL and Visualizing

I have attempted testing this on a few platforms. If you want a great combo for testing failing scenarios, you should try WhatsApp for sharing and Google Photos for Visualizing.

DASH videos (audioless, downloaded from Chromium or Third-Party Websites) -> mixed results. Examples:
- WhatsApp Web: doesn't recognize it as a video and attempts to share it as a file.
- WhatsApp Android: the app's media gallery recognizes the video and thubmnail. It opens the video-sharing view, shows timeline miniatures for editing the video length, but is uncapable of playing the video. If I attempt to send the video, it shows an error "Can't send this video. Choose a different video and try again"
- Google Photos: properly recognizes and displays the video
- Telegram X: properly recognizes, embeds the URL and displays the attached video
Slide videos -> mixed results.
- WhatsApp Web: didn't test it.
- WhatsApp Android: the app's media gallery doesn't recognize the video, but if I use the "share" functionality in another app that recognizes it, WhatsApp is able to share the video
- Google Photos: doesn't recognize the file as a video
- Telegram X: the app's media gallery doesn't recognize it as a video, but if I attempt to send it as a file it attaches as a video once it has uploaded
- Default Viewer (?): if I click the Slide's popup that notifies me that the GIF (?) finished downloading, it opens a video viewer (idk which one) in which I am able to share the file to WhatsApp.
Third-Party Websites -> mixed results.
- WhatsApp Web: some work, some others don't.
- I haven't tested the other platforms.
ffmpeg -> it simply works.

I am unsure how both DASH and HSL video works. Supposing it exports as a standard mp4 file, I can only assume either Reddit has purposefully implemented some kind bug or issue on the video's format in a way it works on browsers but not properly outside, or absolutely all those apps are improperly downloading the video.

Proposed features

The simple one: enable video sharing in Slide's app. Right now, whenever I want to share a cat video with my friends, I have to download it, open it through the Slide's popup, click the share button and choose another app. I wish Slide had a Share button that would automatically save + share it, like RedReader does.
Understand what is going on with v.reddit's videos and develop some bypass/workaround. Idk how Slide does this, but I would attempt to use some kind of ffmpeg wrapper for andrdoid, or manually merging DASH + Audio, or finding another way of downloading HSL, or attempting some conversion between formats, or simply reverse engineering the v.reddit video to understand if it has something wrong with it.

TIA.
