Re: M4A audio file plays back poorly on Android, fine on other platforms

If you're curious, the files all come from the Internet Archive: https://archive.org/details/hhgttgall6 I opened the relevant file there (third book, Part 4) in the web player and the same problem holds. Guess if I have some free time I'll see what I can do with Audacity. At least it's not VLC's fau...

Re: M4A audio file plays back poorly on Android, fine on other platforms

Oh wow, that's really neat, and dumb at the same time. I will check the original MP3 when I get home but I suspect it will have the same issue. I don't suppose you have any clever ideas as to how to fix it? That's not the only place where it happens, and I assume that simply dropping one channel wou...

Re: M4A audio file plays back poorly on Android, fine on other platforms

OK, I've uploaded the complete book. It should have 6 chapter markers, and the most obviously problematic part starts a minute or two into the 4th chapter, right around the 1:24:00 mark.

M4A audio file plays back poorly on Android, fine on other platforms

I have a radio play that I've converted from multiple MP3 tracks to a single M4A audio file using fre:ac. I can't tell it apart from the original files when I play it back on VLC for Windows or any other PC media player. When I play it on VLC for Android, certain sections are inaudible. I have confi...

Re: Suggestions for improved full screen behavior on Android

I spent some time with this yesterday and I think most of the blame falls on LG's "Hide Home touch buttons" setting. I don't know how it got turned on, but it looks like it forces applications into full screen / immersive mode even if they already control that behavior on their own. Sorry ...

Re: Suggestions for improved full screen behavior on Android

Both of these could be related to the fact that I just got a new phone (LG G7 ThinQ) and I think it has some customizable behavior regarding when the soft-key row is shown. I will try to find these settings and see if I can do anything to fix the behavior; I will also test this behavior on another d...

Suggestions for improved full screen behavior on Android

I've been using the Android version for a while now and noticed a couple quirks with the way it implements full screen. I compared its behavior to that of Netflix and YouTube, for reference. First, when navigating media, the app is already using full screen mode. This means that to use my "back...

The "sout-all" option should actually keep all streams

Currently it is impossible to preserve "raw" data streams when streaming out of VLC. People have been asking about this for nearly a decade: * https://forum.videolan.org/viewtopic.php?f=4&t=58237&p=194158 * https://forum.videolan.org/viewtopic.php?f=4&t=93135&p=308648 * htt...

Does "threads=4" in the OP not mean what I thought it meant?

Re: Performance problems with simultaneous transcoding for livehttp

That flag does reduce GPU usage to 0, and increase CPU usage somewhat, but it still won't go over 45% (typically 35-40%) with the command in the OP. It's taking around 20 seconds (!) to produce a 4-second segment. Well, 3 4-second segments, but you get the idea. I logged a few files' worth of output...

Which hardware flag would that be? I see a few different ones in the command line reference.

Re: Performance problems with simultaneous transcoding for livehttp

What log level should I capture? I can run it for a little while and upload the results here, if that helps. You could also run the command yourself, the sample I'm transcoding is the 4K render of Big Buck Bunny available from Blender: http://bbb3d.renderfarming.net/download.html . Let me know which...

Performance problems with simultaneous transcoding for livehttp

I will eventually have a live video feed coming in that I'd like to publish via HLS in a few different bitrates. During initial development, I've been trying to figure out transcoding using VLC just working from a single local file, under the assumption that I can easily replace the input later. (I ...

Re: how to simultaneously create rtsp and livehttp video streams in cvlc from the same live source?

I think 90% of the problems I've seen with VLC command line would be solved if there was a "dry run" option that just echoed back the actual arguments as VLC understands them, without doing anything. Between shell interpolation, quotes/escapes, variable substitution... I spent the better p...

Re: Audio Video not sync'd after transcode

Probably not the place to be posting this, but have you tried Handbrake? If you're coming straight from DVD, I've found no better solution for MP4 transcodes. I use the PS3 setting, which works on my PC, XBox 360, *and* PS3 (the latter two streaming from TVersity). And I've never had the slightest i...
