importing 3gp video (from a mobile phone) with avisynth ?

[derebo]

hi all,

i was wondering if there is a workaround to feed e.g. virtualdub with a .3gp video file capture with a mobile phone. maybe there is a way to get avisynth load that file. any suggestions?

greetings,

directshowsource("video.3gp")

[derebo]

wow!!! gotta try that! ;) thanks for your early reply. this forum is just GREAT! An awesome place to share and learn.

hello there,

i have created test.avs containing this single line:

DirectShowSource("test.3gp")

when i try to open it in virtualdub i get the following message:

#avisynth open failure:
#directshowsource: could no open as video or audio
#video returned: directshowsource couldn't open file test.3gp: file cannot be played. format is not compatible
#audio returned: directshowsource couldn't open file test.3gp: file cannot be played. format is not compatible

the file plays without any problems in nokia multimedia player so i understand the right codecs are installed (at least to decode the video/audio)

MediaInfo reports the following data:

does anyone if there is more code i should add to the .avs file in order to open the .3gp file? any feedback is appreciated!

Change the extension to .mp4 and try again. You'll need an mp4 splitter on your system, of course. You'll never get that audio into avisynth without extracting it, though - there are no directshow filters for AMR that I know of.

*cough*ffdshow*cough* :D

(at least it's on the codecs config page - haven't ever tested it...)

hi,

i've used YAMB (GUI for MP4BOX) to demux test.3gp (354 kb) into:
test_track1.263 (317 kb)
test_track2.amr (30.6 kb)

test.avs :
DirectShowSource("test_track1.263")

cannot be opened by virtualdub, same error. so i have installed ddshow allowing h263 and raw video to be decoded by ddshow. and i keep on getting the same error. so, could you please give any more tips?

edit: now this works! virtualdub shows video and plays audio!
test.avs :
DirectShowSource("test.3gp")

so if .3gp can be opened successfully now that must be fddshow, mustn't it?

greetings!

[scharfis_brain]

if any media player like WMplayer or media player classic can play back your 3gp video, then directshowsource also will be able to.

the nokia software surely comes along with inbuilt decoders so it is independant from the installed codecs on your windoze.

Go into ffdshow's video/audio decoder settings and check "Show tray icon" under "Tray, dialog and paths" - if you get two additional tray icons while the file is open in VirtualDub I'd chalk that up as "yes"... :)

np: The Remote Viewer - Last Night You Said Goodbye, Now It Seems Years (Let Your Heart Draw A Line)

leak, i'll try that out later in the evening ;) thanks everyone for nice feedback. it's been really useful.

here comes MediaInfo report for brand new xvid conversion! ;)

Is it just me, or did the audio go out the window here? ;)

np: B.Fleischmann - Melancholie (Melancholie/Sendestraße (Disc 1))

:mad: sure, you're right. but that's strage then. playing in virtualdub is ok (video and audio), compressing audio seemingly is ok too, but MediaInfo reports no audio some something is to be done about it...

Change the extension to .mp4 and try again. You'll need an mp4 splitter on your system, of course. You'll never get that audio into avisynth without extracting it, though - there are no directshow filters for AMR that I know of.

so how can i get that test_track2.amr into avisynth then? any tips? i'll do some research on my side too, of course.

greetings,

the ffdshow audio decoder is able to decode AMR!
you just need to enable it!

[Leak]

If you're hearing sound in VirtualDub, ffdshow's AMR decoder is already at work.

I guess something went wrong in VirtualDub then...

[derebo]

hi,

yes, AMR decoder is fully at work... media-concert allows conversion from .amr to .wav and then .mp3 compressing is no problem at all.

Brand new MediaInfo report show this time there's video+audio, and i have played the file just to check the audio is there ;)

now, one more problem: while audio is played back at the right rate, video is is played as in fast-forward mode! as the 44s video is played so fast, there's a loop and video is played back once and again everytime until the end of 44s. i think this might be due to the fact that original test.3gp has a variable framerate as MediaInfo reports:


Frame rate : 5.471 fps
Minimum frame rate : 2.143 fps
Maximum frame rate : 15.002 fps


i have left virtualdub video > frame rate > no change and output file is:


Frame rate : 25.000 fps


i have done the same again video > frame rate > change so video and audio durations match, but the end result is the same. so has anyone faced a situation like this before? dealing with variable framerate?

Use DirectShowSource("file",fps=15,convertfps=true), which will undo the VFR, then re-encode with that. There are other methods, but they're all more complex and some you can't use with AVI.
