  • FFmpeg playing audio slowly after conversion from AAC

    18 janvier 2014, par AnthonyM

    I'm attempting to convert an AAC audio stream for playback. I've discovered that I need to convert from AV_SAMPLE_FMT_FLTP to AV_SAMPLE_FMT_S16 but when I do so the audio plays back at about half speed.

    swr = swr_alloc();
    
assert(av_opt_set_int(swr, "in_channel_layout", audioContext->channel_layout, 0) == 0);
    
assert(av_opt_set_int(swr, "out_channel_layout", audioContext->channel_layout, 0) == 0);
    
assert(av_opt_set_int(swr, "in_sample_rate", audioContext->sample_rate, 0) == 0);
    
assert(av_opt_set_int(swr, "out_sample_rate", 44100, 0) == 0);
    
assert(av_opt_set_int(swr, "in_sample_fmt", audioContext->sample_fmt, 0) == 0);
    
assert(av_opt_set_int(swr, "out_sample_fmt", AV_SAMPLE_FMT_S16, 0) == 0);
    
swr_init(swr);

    There is my code to convert. The input sample rate is 44100 and the audio is stereo.

    I call the code with

    swr_convert(swr, &output, aDecodedFrame->nb_samples, (const uint8_t**)aDecodedFrame->extended_data, aDecodedFrame->nb_samples) >= 0)

  • arm : vp9itxfm : Reorder iadst16 coeffs

    31 décembre 2016, par Martin Storsjö
    arm : vp9itxfm : Reorder iadst16 coeffs

    This matches the order they are in the 16 bpp version.
    

    There they are in this order, to make sure we access them in the
    
same order they are declared, easing loading only half of the
    
coefficients at a time.
    

    This makes the 8 bpp version match the 16 bpp version better.
    

    This is cherrypicked from libav commit
    
08074c092d8c97d71c5986e5325e97ffc956119d.

  • IP cameras and Nginx

    28 octobre 2015, par JocBro1

    The goal is to connect a large number of IP cameras to a server Nginx archiving all going stream video files to mp4 (H264 + ACC) to play them on different devices.

    Module was installed nginx-rtmp-module (for HLS and RTMP).

    avconv takes a stream from the cameras at rtsp and gives to nginx’s rtmp.

    Recording is as nginx to flv and then the files in the desired format convert to mp4. (Here is a question for information about the file is video-codec : h264, audio-codec : acc, but if you save them to mp4, iDevises not be played on, we have yet to convert. Why ?)

    The problem in general is that after a certain time (say 20-30 minutes) nginx more than half of the cameras stops processing, play video and record video files from the camera, if you look at this live stream with rtmp - he does not play, but hls - played.

    Sorry for translater’s english)

    People help me, please !
