media.captureVideo / media.playVideo cross platform incompatibilty?

Audio and Graphics
#1

I’m recording a video on droid using media.captureVideo

I"'m saving it to a server, downloading it, and playing on an iphone (plays back fine on the droid).

On iOS, the media.playVideo returns a playback error in it’s event (failedToPlayToEnd). The recorded droid file (from android 2.3.6) is a .3gp file. (As a side note, captureVideo records .mp4 on iOS…)

Anyways, the .3gp file fails to play on iOS through media.playVideo.

Calls to play it on iOS using native newVideo also fail. However, the sdk doesn’t fail on the video:load call. After the video:load call, checking the video length paramter indicates the correct time length of the loaded .3gp file, so it seems like the sdk is able to read the metadata/general info about the video on iOS.

However, the video never renders to the screen, and the videoListener function (installing a listener on the object) never gets called with the “ready” event (which it normally does when loading an mp4).

So the bottom line for android media.captureVideo / media.PlayVideo, cross platform (from my android 2.3.6 anyways), is it doesn’t look like it’s working.

Haven’t had a chance to try a newer droid, and see if the video file generated is different. Has anyone tried this with a new droid, or did CoronaLabs give this a try?

Hi,

I just gave this a try and it worked.  What I did was:

  1. Use media.captureVideo( { listener = onComplete } ) to capture a video on 2 Android devices: Nexus 7(4.3) and a Samsung SII(2.3.4)

  2. Manually extract the files from the devices via a file explorer

  3. Create a new project with the 2 files that were extracted

  4. Use media.playVideo to play those 2 videos on an iPad 3 running iOS 6.x

One of the devices created a 3gp file while the other created a mp4.

The exact code I used for 1 is the following:

local onVideoComplete = function(event) print("video session ended") end local function onComplete(event) if event.completed then media.playVideo(event.url, media.remoteSource, true, onVideoComplete) print(event.duration) print(event.fileSize) end end if media.hasSource( media.Camera ) then media.captureVideo( { listener = onComplete } ) else native.showAlert( "Corona", "This device does not have a camera.", { "OK" } ) end

and the code for 4 is the following:

local function play1(event) print("3gp") media.playVideo("Video1.3gp") end local function play2(event) print("mp4") media.playVideo("20131121\_181738.mp4") end local button = display.newRect(120,240,80,70) local button1 = display.newRect(220,240,80,70) button:addEventListener("tap", play1 ) button1:addEventListener("tap", play2 )

@dchan – Great! thanks for the help!

I don’t doubt at all it plays from the system.ResourceDirectory… However, it’s not working from the system.TemporaryDirectory. I’m guessing it’s where it attaches the path, since no form I’ve used will get it to play my .3gps from the temporaryDirectory when I use it in the playVideo() call. All of these forms have failed for me in trying to play a 3gp from there (mp4’s play fine from there though)

[lua]

    fName = “myVideo.3gp” – Is other name actually, downloaded from server to temporaryDirectory, originally generated from a corona app

    media.playVideo( fName, system.TemporaryDirectory, true, fullVidDone )    – player shows black, exits        

    fName = system.pathForFile( fName, system.TemporaryDirectory)   – Try it a little differently…

    media.playVideo( fName, media.RemoteSource, true, fullVidDone )        – player shows black, exits

    media.playVideo( fName, true, fullVidDone )            – Doesn’t even switch to player
 

[/lua]

Do you have a sample project of something I can use to download to the temp dir and play it?

#5

My project is gigantic, but you should be able to basically use this instead of your (4) code to test your existing file

— lua formatters not working :frowning:

local fName = “Video1.3gp”  – Original file recorded on droid

local rfilePath = system.pathForFile( fName, system.ResourceDirectory )
local wfilePath = system.pathForFile( fName, system.TemporaryDirectory )

local rfh = io.open( rfilePath, “rb” )
local wfh = io.open( wfilePath, “wb” )

if not wfh then
print( “writeFileName open error!” )
results = false – error
else
– Read the file from the Resource directory and write it to the destination directory
local data = rfh:read( “*a” )

if not data then
   print( “read error!” )
   results = false – error
else
   if not wfh:write( data ) then
   print( “write error!” )
   results = false – error
end
end

– Clean up our file handles
rfh:close()
wfh:close()

– now play it from the temp directory

media.playVideo(fName, system.TemporaryDirectory

#6

That worked as well.  Have you tried just playing the 3gp normally to make sure you can actually play it on the device?

#7

OK, that is weird. Can you just try one more version to make sure – because my results are drastically different and I’ve rechecked many times… This version just makes it a different name to be sure it’s not playing the one from the resource folder…

If that plays (on a device, not osx – which it works on), then I’m pretty stumped…

Also: yes, I’ve emailed the 3gps from the droids to ios and played them successfully on the ios devices…

— lua formatters not working :frowning:

local fName = “Video1.3gp”  – Original file recorded on droid

local fName2 = “Video2.3gp”  – Different filename

local rfilePath = system.pathForFile( fName, system.ResourceDirectory )
local wfilePath = system.pathForFile( fName2, system.TemporaryDirectory )

local rfh = io.open( rfilePath, “rb” )
local wfh = io.open( wfilePath, “wb” )

if not wfh then
print( “writeFileName open error!” )
results = false – error
else
– Read the file from the Resource directory and write it to the destination directory
local data = rfh:read( “*a” )

if not data then
   print( “read error!” )
   results = false – error
else
   if not wfh:write( data ) then
   print( “write error!” )
   results = false – error
end
end

– Clean up our file handles
rfh:close()
wfh:close()

– now play it from the temp directory

media.playVideo(fName2, system.TemporaryDirectory)

#8

That worked as well although you did have a syntax error in there.  I assume the else on line 15 is supposed to be an end.  I’ve attached the 3gp video that I’m using to test with.  Does that file work for you?

edit: I had to change the extension to .txt so that the forums let me attach it.  Please change the extension back to 3gp.

#9

OK, thanks for all your help dchan. I copied your file and tried it, and it worked…

My original 3gp didnt, blank player… I did get a different 3gp to play in the player with that code though, I think it was from a newer droid. Having 3 3gp files, recorded on various droids, 2 worked, 1 didn’t, I looked at the files in g-spot (nice free container/codec inspection utility).

Your 3gp:

isom: MP4  Base Media v1 [IS0 14496-12:2003]

  • 3gp4: 3GPP Media (.3GP) Release 4
    Recommended Display Size: 1920 x 1080
    Created:     2013 Oct 24   16:57:20

My working 3gp (from android jelly bean/nexus 7):

3gp6: 3GPP Media (.3GP) Release 6 Basic Profile

  • isom: MP4  Base Media v1 [IS0 14496-12:2003]
    Recommended Display Size: 480 x 360
    Created:     2013 Oct 11   23:20:08
    Modified:     2013 Oct 11   23:20:08
     

My not working 3gp (from android 2.3.6):

3gp4: 3GPP Media (.3GP) Release 4
Recommended Display Size: 320 x 240
 

I’m going to go back through things, as I hadn’t noticed the I could playback the nexus 7 videos on ios before…

But a LOT thanks for your help dchan… I guess the best scenario would be if the older phones just dont have the encoding (until android 3.0? http://developer.android.com/guide/appendix/media-formats.html – most of the way down the page it shows pre 3.0 only doing h.263 encoding, and after 3.0 h.264 … Could that be why?) 

I’ll let you know if I find out more specifics, thanks again!

#10

Can you attach your non working 3gp file so I can play around with it?  Thanks.

#11

Sure thing.

#12

@dchan: OK, my mistake testing above –

Although I can playback your 3gp file on iOS, I can’t playback 3gp’s on iOS from either of my droids. Attached is another example 3gp, this one from my nexus 7 (Jelly bean).

This 3gp has something in common with the other one, the audio compression. And the audio compression on both of these failing ones is listed in the gspot utility as: “samr: AMR Narrowband”… Note that these .3gp’s were recorded in corona using the “Medium” record setting for media.captureVideo, which the documentation says defaults to “low” on android…

Your .3gp file appears to be recorded from the “high” setting (given it’s 1920x1080 size), and gspot lists your files audio codec as: " mp4a: MPEG-4 AAC LC"

A couple questions, if you’ve got time for any of them – Does this 3gp, from a new nexus 7 (recorded with “low” in media.captureVideo) playback for you on iOS? (It does in osx/windows, but not on an ios device for me…) If you record a video set to medium/low on your own android device using media.captureVideo, do you get the same “amr narrowband” audio codec result? Will your own medium/low video play back on ios using media.playVideo? (basically, is that how we’re getting different results / why it won’t play back… because of my low setting/codec, and yours?)

NOTE: In gspot, at the bottom of the main window under the “Proposed Codec Solutions and tests”, you click the “1” test button in the “MS/AV” column, gspot throws an error: “Partial render failure: Video could be rendered, but the audio could not.” It’s got more details about the error / codecs, but, it looks like some kind of error to gspot it seems (you’re hi-res 3gp does not throw this gspot error).

#13

@dchan – and one more data point… (Recording “medium” / “low” video record quality on droid)… (seen in build 2090 and earlier)

I’m getting a major error even attempting to record low/medium quality on my Nexus 7 (last years model). 50% or more of the time that I try and record video, the camera activity crashes. I think it is also related to the audio… (As I mentioned above, I think the playback of 3gp on ios is also failing because of the low/medium android audio format)…

In this case, the recorder failing, I have a good log from the nexus (again, this is while recording “medium” quality on android - the camera activity pops up on screen, and > 50% of the time crashes right out):

http://stackoverflow.com/questions/6758167/about-amr-audio-file-playing-issue-on-different-devices

The second link suggests it’s possible to customize the videos audio encoder to “AMR_WB” or “AAC” (which it looks like might be compatible in ios).

Hi,

I just gave this a try and it worked.  What I did was:

  1. Use media.captureVideo( { listener = onComplete } ) to capture a video on 2 Android devices: Nexus 7(4.3) and a Samsung SII(2.3.4)

  2. Manually extract the files from the devices via a file explorer

  3. Create a new project with the 2 files that were extracted

  4. Use media.playVideo to play those 2 videos on an iPad 3 running iOS 6.x

One of the devices created a 3gp file while the other created a mp4.

The exact code I used for 1 is the following:

local onVideoComplete = function(event) print("video session ended") end local function onComplete(event) if event.completed then media.playVideo(event.url, media.remoteSource, true, onVideoComplete) print(event.duration) print(event.fileSize) end end if media.hasSource( media.Camera ) then media.captureVideo( { listener = onComplete } ) else native.showAlert( "Corona", "This device does not have a camera.", { "OK" } ) end

and the code for 4 is the following:

local function play1(event) print("3gp") media.playVideo("Video1.3gp") end local function play2(event) print("mp4") media.playVideo("20131121\_181738.mp4") end local button = display.newRect(120,240,80,70) local button1 = display.newRect(220,240,80,70) button:addEventListener("tap", play1 ) button1:addEventListener("tap", play2 )

@dchan – Great! thanks for the help!

I don’t doubt at all it plays from the system.ResourceDirectory… However, it’s not working from the system.TemporaryDirectory. I’m guessing it’s where it attaches the path, since no form I’ve used will get it to play my .3gps from the temporaryDirectory when I use it in the playVideo() call. All of these forms have failed for me in trying to play a 3gp from there (mp4’s play fine from there though)

[lua]

    fName = “myVideo.3gp” – Is other name actually, downloaded from server to temporaryDirectory, originally generated from a corona app

    media.playVideo( fName, system.TemporaryDirectory, true, fullVidDone )    – player shows black, exits        

    fName = system.pathForFile( fName, system.TemporaryDirectory)   – Try it a little differently…

    media.playVideo( fName, media.RemoteSource, true, fullVidDone )        – player shows black, exits

    media.playVideo( fName, true, fullVidDone )            – Doesn’t even switch to player
 

[/lua]

Do you have a sample project of something I can use to download to the temp dir and play it?

#17

My project is gigantic, but you should be able to basically use this instead of your (4) code to test your existing file

— lua formatters not working :frowning:

local fName = “Video1.3gp”  – Original file recorded on droid

local rfilePath = system.pathForFile( fName, system.ResourceDirectory )
local wfilePath = system.pathForFile( fName, system.TemporaryDirectory )

local rfh = io.open( rfilePath, “rb” )
local wfh = io.open( wfilePath, “wb” )

if not wfh then
print( “writeFileName open error!” )
results = false – error
else
– Read the file from the Resource directory and write it to the destination directory
local data = rfh:read( “*a” )

if not data then
   print( “read error!” )
   results = false – error
else
   if not wfh:write( data ) then
   print( “write error!” )
   results = false – error
end
end

– Clean up our file handles
rfh:close()
wfh:close()

– now play it from the temp directory

media.playVideo(fName, system.TemporaryDirectory

That worked as well.  Have you tried just playing the 3gp normally to make sure you can actually play it on the device?

#19

OK, that is weird. Can you just try one more version to make sure – because my results are drastically different and I’ve rechecked many times… This version just makes it a different name to be sure it’s not playing the one from the resource folder…

If that plays (on a device, not osx – which it works on), then I’m pretty stumped…

Also: yes, I’ve emailed the 3gps from the droids to ios and played them successfully on the ios devices…

local fName = “Video1.3gp”  – Original file recorded on droid

local fName2 = “Video2.3gp”  – Different filename

local rfilePath = system.pathForFile( fName, system.ResourceDirectory )

local rfh = io.open( rfilePath, “rb” )
local wfh = io.open( wfilePath, “wb” )

end

– now play it from the temp directory

media.playVideo(fName2, system.TemporaryDirectory)

#20

That worked as well although you did have a syntax error in there.  I assume the else on line 15 is supposed to be an end.  I’ve attached the 3gp video that I’m using to test with.  Does that file work for you?

edit: I had to change the extension to .txt so that the forums let me attach it.  Please change the extension back to 3gp.
