I have multiple input devices (Cameras), every one of them is encoded to
their own file. Everything is working fine. I have only one input
AVFormatContext. This is how cameras are opened
for (int i = 0; i < CameraList.Count; i++)
{
var camera = CameraList[i];
AVDictionary* optionalOpts;
if (!string.IsNullOrEmpty(camera.InputResolution))
ffmpeg.av_dict_set(&optionalOpts, "video_size",
camera.InputResolution, 0);
ffmpeg.av_dict_copy(&optionalOpts, options, 0);
AVInputFormat* inputFormat = null;
if (!string.IsNullOrEmpty(camera.Format))
{
inputFormat =
ffmpeg.av_find_input_format(camera.Format);
if (inputFormat == null)
// exception
}
if (ffmpeg.avformat_open_input(&pInputFmtCtx,
camera.Url, inputFormat, &optionalOpts) != 0)
{
if (ffmpeg.avformat_open_input(&pInputFmtCtx,
camera.Url, inputFormat, &options) != 0)
// exception
}
}
The problem is that the application crashes when having more than one
input, specifically here:
fixed (AVFormatContext** p = &InputFormatContext)
ffmpeg.avformat_close_input(p);
If I have single input (one video and one audio stream) everything is fine.
There is no errors thrown, just crash and that's it.What am I doing wrong?
