  • lavf : deprecate av_stream_get_end_pts()

    lavf : deprecate av_stream_get_end_pts()

    According to its documentation it returns "pts of the last muxed packet
    
+ its duration", but the value it actually returns right now is
    
(possibly guessed) dts after muxer-internal bitstream filtering (if
    
any).
    

    This function was added for ffmpeg.c, but it is not used there anymore.
    
Since the value it returns is ill-defined and so inappropriate for any
    
serious use, deprecate it.

  • avcodec/vp6 : Don't reload unnecessarily often in get_vlc2()

    17 avril, par Andreas Rheinhardt
    avcodec/vp6 : Don't reload unnecessarily often in get_vlc2()

    The VLC trees used here have very few different codes
    
and are therefore guaranteed to not be very deep : The AC/DC
    
VLCs have 12 elements and therefore a depth <= 11 whereas
    
the run VLCs have only nine elements and therefore a depth <= 8.
    
This allows to reduce the worst-case number of reloads for
    
reading a VLC code.

  • Android : How to convert WAV/PCM to another audio format without MediaCodec API

    3 octobre 2013, par khelkun

    I've searched around the web and stackoverflow during a long time about this subject. I know it has been discussed many times but I'm looking for a friendly opinion on my use case.

    I have a vocal dictation application which uses android.media.AudioRecord. It allows me to edit the recorded raw PCM buffer : insert a new record inside it, delete a certain period in the record, append a new record at the end. The result is a WAV file, but it's a bit too big file for my needs, so I want to convert it to smaller file format.

    android.media.MediaCodec could have been the solution, but it requires API level 16 which is a too high restriction in my situation.

    It sounds to me that I only have 2 options :

    1. Use the NDK and an android portage of ffmpeg like the guardian project android-ffmpeg-java. But this solution sounds a bit too hard for me so far.

    2. Recording with android.media.MediaRecorder to output an audio 3GPP file encoded with the AMR_NB encoder. Then I'll have to understand this 3GPP file header and the AMR_NB format in details to be able to perform the audio editing operations on my record.

    I must also add that creating a zip file of the WAV file is not a valid option for me.

    Does someone know another option please ? And is option 2. actually possible to achieve ?

    Thanks for your time !
