When playing a video file/stream, gracefully transition from video+audio to audio only & back when screen turned off & on

I generally download the HD/SD video content for content such as TWiT.tv (TWiT, TWiG, AAA, TNT, etc.); Buzz Out Loud; TEDTalks; Mars Hill Church sermons; LifeChurch.tv sermons; etc. and will flip flop (manually) between video/audio as I'm doing other things such as walking to/from the bus (audio but sometimes video) riding the bus (video, but sometimes audio), walking the dog (usually just audio), etc.

It would be really nice if DoggCatcher could automatically and gracefully transition from video+audio to audio only & back when the screen is turned off & on... like YouTube does.

I'm not sure how they do it, and I doubt they publish the method, but it wouldn't surprise me if they simply continue rendering the video+audio even though the screen is off since virtually all of these devices have hardware accelerated DSPs which decode the stream using minimal power and it is the screen/backlight which is the major drain of battery.

Please create a preference (or whatever implementation you see fit) to enable the graceful and automatic transition, preferably without interruption, to/from video+audio <-> audio only when the display is on <-> off.

Thank you for a great app, constantly being improved, and for entertaining our requests.

Humbly & respectfully,
Paul

Is the behavior that you're

Is the behavior that you're seeing in the youtube app that you play a video and then when you lock the screen, the audio continues to play?

Yes. When YouTube is playing

Yes.
When YouTube is playing a video and the screen is locked or off, the audio continues to play without interruption.
When the screen is turned back on and unlocked, the video is visible and playback of the audio+video continues without interruption.

I suspect the YouTube app does not discontinue rendering the video even though the screen is off/locked.

Hmm, I'm not sure if we have control over that with the android media player. The youtube player is certainly something custom written, where they could possible suspend the video rendering only. I may have to transparently switch between playing video and video as audio.

I created an issue for this.

This would be very good!

I have pretty much the same experience as PaulMEdwards (though instead of church sermons it's The Atheist Experience ;) ) - following videocasts during which I usually don't need the picture, but which sometimes makes a nice addition if environment permits, or is even for a short while needed to follow the content. As with him, the use between audio & video changes both depending on environment and the content.

In another similar suggestion you mentioned the ability to open playback as audio, and reopen it as video. It does help, but as you say, it's cumbersome - not just little, a lot. One very normal use case would be to take a quick glance at the video to see if picture is relevant or not.

While YouTube indeed does the manage the switch completelly gracefully since they're using a custom video player, it seems like a pretty big task to write a custom video player for just this. So if it's possible to do a transition from video to audio in some more reasonable way, with only user activity being the lock screen button, I wouldn't mind even having a small jerk or pause in the audio at the transition. The main thing is not having to fiddle with any controls.

As a sidenote, do you know if any custom firmware solves this? That is, allows the integrated player to continue playback while sceen is locked?

I also noticed there's an option to use an external video player in DoggCatcher. Do you know of a simple video player that would support this feature? Also, does using an external video player always mean that DoggCatcher cannot know and store the position? (If so, that would pretty much kill the feature for me anyway - I rarely go through a single episode in one go.)

Yep, I agree, we may be able

Yep, I agree, we may be able to pull it off with just a little audio blip as we switch from an audio to video player.

I can't speak to any custom roms, but using an external player is probably going to make things worse for you. There isn't any integration between DC and an external player, it basically a hand-off delegation to the player.

Thanks for the feedback.

Best case: not just lock screen

As a further note (that might be sort of obvious) I want to point out that in best case scenario this switch shouldn't happen with just lock screen, but with any exit from video. So that you can jump to home screen to do other things with your phone, while still seamlessly continuing to listen to the "video" you had playing.

However, the lock screen would definately be the most important use case.

Yep, I agree. It would probably need to be a preference because I can see some people still wanting the current behavior though.

Continue playing a video podcast in the background

Has there been any progress on this yet. I listen to video podcasts while driving. Yes mostly listen and I'm in low traffic on large highways most of the time. The video is there so I can glance at the screen to see what they are talking about.

Problem is I use my Bluetooth to my car system and when a phone call comes in the video is paused but when the call is over it doesn't switch back to the video but back to the select screen of videos (much less hand free). This happens all day long with calls. Yet the audio mode of DC pauses the podcast and continues when the call ends. Switching video to audio when locked or doing something else would be great but for me resuming the video after a call would be more important.

But all in all it's a great app!

I haven't work on this at all yet, but I do see the need to focus some more on better video support. It has always been a second class citizen, but it shouldn't be.

Thanks for the feedback.

Any news regarding this

Any news regarding this subject? I made the switch from pocket casts, and I love the app, I only miss this feature, being able to change audio/video at will. Also, you're right, video support is lacking, but I'm sure it will get better.

Regards,

No progress on this yet, I'm working now on enhancing the user playlists and knocking out some bugs.

Workaround

If you download a video podcast, but play it through the Gallery app (rather than through DoggCatcher), you can then use the power button to lock/unlock the screen during video playback. Since it isn't easy to tell which episode you're playing through the Gallery, it would be better if this feature were enabled in the app, but this might serve as a workaround in the meantime.

Love the app otherwise!
