I installed the latest version and the callback is not called if I pass non-existing/broken link to avio_open2 or avformat_open_input Even av_dict_set(&options, "timeout", "5", 0); does not have any effect. The call just hangs. Note that if the link exists the callback is working fine. Here is the small code (actually copied from the mentioned ticked above). Compiled in Visual Studio 2015. Includes/libraries/DLLs are all up to date from https://ffmpeg.zeranoe.com/builds/ {{{ #include <Windows.h> #include <libavcodec\avcodec.h> #include <libavformat\avformat.h> #include <stdio.h> static int interrupt_cb(void *ctx) { printf("Interrupt callback called\n"); return 0; } int main(int argc, char *argv[]) { AVFormatContext *pFormatCtx; if (argc < 2) { printf("Please provide a movie file\n"); return -1; } // Register all formats and codecs av_register_all(); avcodec_register_all(); avformat_network_init(); // Open video file pFormatCtx = avformat_alloc_context(); pFormatCtx->interrupt_callback.callback = interrupt_cb; pFormatCtx->interrupt_callback.opaque = pFormatCtx; AVDictionary* options = NULL; AVIOContext* av = NULL; AVIOInterruptCB cb = { .callback = interrupt_cb, .opaque = NULL, }; //av_dict_set(&options, "timeout", "5", 0); // hangs int ret = avio_open2(&av, argv[1], AVIO_FLAG_READ, &cb, &options); // hangs if (avformat_open_input(&pFormatCtx, argv[1], NULL, &options) != 0) return -1; // Couldn't open file avformat_close_input(pFormatCtx); printf("Exiting\n"); return 0; } }}} -- Ticket URL: <https://trac.ffmpeg.org/ticket/6529> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker _______________________________________________ FFmpeg-trac mailing list FFmpeg-trac@avcodec.org http://ffmpeg.org/mailman/listinfo/ffmpeg-trac
