3gp

Is it possible to convert an AVI file to 3gp in C# ? If so how could I do this? Any ideas will be appreciated, thanks in advance. It depends what you mean by "convert". Both 3GP and AVI are wrapper formats, so are you merely trying to change the container format, or do you want to re-encode the streams as well? Either way, you should probably take a look at ffmpeg ( Windows info ). For simple cases (i.e. you have the file, want a single output file), you should probably consider it invoking it on the command-line (i.e. System.Diagnostics.Process ), which is much easier (and doesn't involve any

I've checked on stackoverflow and searched all over the internet but haven't been able to find a solution to my problem. In my app I need to have control over the way a youtube video is shown. I need to have control over the MPMoviePlayerController and thereby MPMediaPlayback properties. So actually I have 3 questions: Is there already a solution for playing youtube videos directly in a MPMoviePlayerController that you create yourself? Is it somehow possible to play the RTSP - 3GP links youtube has for the mobile site in the MPMoviePlayerController? (Right now it refuses the RTSP format) Is it

I have an app which allows user to import media (videos, photos, audio) which will then be managed by the application (as evidence). I've found that some audio recording apps will save audio in .3gp format (specifically Whats App messenger). If i get the mime type using the following code: MimeTypeMap.getSingleton().getMimeTypeFromExtension(fileExtension); it will come back as video/3gp which my app takes to mean it is of the type "video" and tries to make thumbnails and what not (I use the first part of the mime type to determine what type my app categorizes it as). However it is audio so

I am using cordova-plugin-media to record voice(with pause and resume features) in my ionic app for android. After I record it I need to get base64 string in order to play it using html audio tag. And the problem is: if I am trying to save recording which was paused and resumed as 3gp file('voice.3gp'), then when I use readAsDataURL method of cordova-plugin-file , I don't receive anything(the callback simply not called). If I am trying to save it as mp3 or wav file, then I receive only 1st part of the recording(before pause). I suppose that the proper audio file extension should be 3gp as this

Playing a 3gp file with HTML5 does not work. I have Firefox 16 and Chromium Version 22 and the result I got is the following: No video with supported format and MIME type found. Here's the code I used: <video controls="controls"> <source src="rtsp://v2.cache2.c.youtube.com/CiQLENy73wIaGwlkcZfgin6szRMYDSANFEgGUghzdGFuZGFyZAw=/0/0/0/video.3gp" type="video/3gpp"> Your browser does not support the video tag. </video> 来源： https://stackoverflow.com/questions/13220019/how-to-play-3gp-video-in-html5

I am trying to stream video from android camera through local unix socket and write file from stream to sdcard. Everything works fine, except file is not playable with any player. It's because Android not filling some gaps in the file because socket is not seekable. As I understand I need to make some modifications after video stream is over. I read several articles here , here and here , but none of them helped me. I am playing with hex editor to learn how to do it manually, so afterwards it will be trivial to do the same in the Android code. Here is sample file that saved from stream: https:
