  • avcodec/v4l2_m2m_dec : remove redundant packet and fix double free

    16 juillet 2020, par Andriy Gelman
    avcodec/v4l2_m2m_dec : remove redundant packet and fix double free

    v4l2_receive_frame() uses two packets s->buf_pkt and avpkt. If avpkt
    
cannot be enqueued, the packet is buffered in s->buf_pkt and enqueued in
    
the next call. Currently the ownership transfer between the two packets
    
is not properly handled. A double free occurs if
    
ff_v4l2_context_enqueue_packet() returns EAGAIN and v4l2_try_start
    
returns EINVAL.
    

    In fact, having two AVPackets is not needed and everything can be
    
handled by s->buf_pkt.
    

    This commit removes the local avpkt from v4l2_receive_frame(), meaning
    
that the ownership transfer doesn't need to be handled and the double
    
free is fixed.

  • avformat/avformat : Update av_read_frame() documentation

    1er décembre 2019, par Andreas Rheinhardt
    avformat/avformat : Update av_read_frame() documentation

    This commit updates the documentation of av_read_frame() to match its
    
actual behaviour in several ways :
    

    1. On success, av_read_frame() always returns refcounted packets.
    
2. It can handle uninitialized packets.
    
3. On error, it always returns blank packets.
    

    This will allow callers to not initialize or unref unnecessarily.

  • How to get DirectShow device list with ffmpeg in c++ ?

    24 août 2018, par fyo

    I’m trying to get dshow device list with ffmpeg. I cannot get it but ffmpeg gets it by its own. Here is the code. It returns AVERROR(ENOSYS) for avdevice_list_input_sources. But avformat_open_input prints all devices. How can I get dshow devices and options in c++ code.

        avdevice_register_all();
    
    AVInputFormat *iformat = av_find_input_format("dshow");
    
    printf("========Device Info=============\n");
    
    AVDeviceInfoList *device_list = NULL;
    
    AVDictionary* options = NULL;
    
    //av_dict_set(&amp;options, "list_devices", "true", 0);
    
    int result = avdevice_list_input_sources(iformat, NULL, options, &amp;device_list);
    

    
    if (result &lt; 0)
    
        printf("Error Code:%s\n", av_err2str(result));//Returns -40 AVERROR(ENOSYS)
    
    else printf("Devices count:%d\n", result);
    

    
    AVFormatContext *pFormatCtx = avformat_alloc_context();
    
    AVDictionary* options2 = NULL;
    
    av_dict_set(&amp;options2, "list_devices", "true", 0);
    
    avformat_open_input(&amp;pFormatCtx, NULL, iformat, &amp;options2);
    
    printf("================================\n");
