  • Python SWIG bindings with SomeType ** as function argument

    2 mai 2013, par vericule

    I couldn't find any working Python bindings for ffmpeg, so I decided to generate one with SWIG. Generation was quick and easy (no customization, just default SWIG interface), but these a problem using some functions like int avformat_open_input(AVFormatContext **ps, const char *filename, AVInputFormat *fmt, AVDictionary **options); from libavformat/avformat.h. Using C this can be run simply by :

    AVFormatContext *pFormatCtx = NULL;
    
int status;
    
status = avformat_open_input(&pFormatCtx, '/path/to/my/file.ext', NULL, NULL);

    In Python I try following :

    >>> from ppmpeg import *
    
>>> av_register_all()
    
>>> FormatCtx = AVFormatContext()
    
>>> FormatCtx
    
 >
    
>>> avformat_open_input(FormatCtx, '/path/to/my/file.ext', None, None)
    
Traceback (most recent call last):
    
   File "<stdin>", line 1, in <module>
    
TypeError: in method &#39;avformat_open_input&#39;, argument 1 of type &#39;AVFormatContext **&#39;
    
</module></stdin>

    Problem is that Python do not have & equivalent. I tried to use cpointer.i and its pointer_class (%pointer_class(AVFormatContext, new_ctx)), but new_ctx() returns pointer and this is not I want definitely. %pointer_class(AVFormatContext *, new_ctx) is illegal and gives syntax error. I would be grateful for any help. Thanks.

    EDIT :
    I forgot to mention I tried to use typemaps, but don't know how to write custom typemap for struct and documentation has only examples for basic types like int or float...

  • Playing encrypted m4a on Android

    20 novembre 2013, par Fixee

    I'm pulling down encrypted music, decrypting on-the-fly to m4a plaintext buffer and want to then play this music on Android (4.x). It appears the options are bleak :

    1. Write the buffer to disk and use MediaPlayer() with a FileDescriptor
    2. Write the buffer to disk and use a proxy like nano to serve MediaPlayer() via a URI
    3. Decode the buffer to PCM and use AudioTrack to play it

    Options 1 and 2 require writing plaintext to SD, which isn't acceptable. Option 3 requires decoding in software (with, eg, ffmpeg) which seems ridiculous : if there are hardware decoders on the device we can't use them. And if there is a software decoder, we can't access it and put yet another decoder on the device (ffmpeg's).

    Note that using OpenSL doesn't help at all : you still cannot play m4a's from a buffer. Is there another way ?

  • ffmpeg live transcoding faster alternative ?

    6 août 2014, par ppoeas

    Is there any opensource alternative to ffmpeg and VLC to live video transcoding from HTTP streaming to RTMP or other ?

    ffmpeg caused my CPU (AMD 4.0GHZ 8Core) is loaded 100% with only 8 SD streams.

    Thanks for help.

    PS.
    I think I don’t need to transcode my video, I can also stream with something like http video proxy. Source is in HTTP streaming format, also I am under Linux.
