Apache2 won't start - no listening sockets available - ubuntu 14.04

Question

I'm using fffmpeg to do some video work,and now I get some troulbe. I don't know how to get the progress of transcode. I check ffmpeg.c and found that most time cost is 'transcode', here is the source code of ffmpeg.c#transcode:

static int transcode(void)
    {
    XLOGD("==========transcode==========");
   ...
    XLOGD("start transcode");
    while (!received_sigterm) {
        int64_t cur_time= av_gettime_relative();

        /* if 'q' pressed, exits */
        if (stdin_interaction)
            if (check_keyboard_interaction(cur_time) < 0)
                break;

        /* check if there's any stream where output is still needed */
        if (!need_output()) {
            av_log(NULL, AV_LOG_VERBOSE, "No more output streams to write 
            to, finishing.\n");
            break;
        }

        ret = transcode_step();
        if (ret < 0 && ret != AVERROR_EOF) {
            av_log(NULL, AV_LOG_ERROR, "Error while filtering: %s\n", 
            av_err2str(ret));
            break;
        }

        /* dump report by using the output first video and audio streams */
        print_report(0, timer_start, cur_time);
    }

    return ret;
   }

I called ffmpeg like this:

int execute(int argc, char **argv) {

if CONFIG_AVDEVICE

/* parse options and open all input/output files */
ret = ffmpeg_parse_options(argc, argv);
if (ret < 0){
    return exit_program(1);
}

if (nb_output_files <= 0 && nb_input_files == 0) {
    show_usage();
    av_log(NULL, AV_LOG_WARNING, "Use -h to get full help or, even better, run 'man %s'\n", program_name);
    return exit_program(1);
}

/* file converter / grab */
if (nb_output_files <= 0) {
    av_log(NULL, AV_LOG_FATAL, "At least one output file must be specified\n");
    return exit_program(1);
}

if (nb_input_files == 0) {
    av_log(NULL, AV_LOG_FATAL, "At least one input file must be specified\n");
    return exit_program(1);
}

for (i = 0; i < nb_output_files; i++) {
    if (strcmp(output_files[i]->ctx->oformat->name, "rtp"))
        want_sdp = 0;
}

current_time = ti = getutime();
if (transcode() < 0){
    return exit_program(1);
}

return main_return_code; }

Any ideas anyone?

Many thanks in advance.

many thanks, now I figure it out. in ffmpeg.c, function

print_report(int is_last_report, int64_t timer_start, int64_t cur_time),

there I got some code block:

secs = FFABS(pts) / AV_TIME_BASE;
    us = FFABS(pts) % AV_TIME_BASE;
    mins = secs / 60;
    secs %= 60;
    hours = mins / 60;
    mins %= 60;

from this I can know the duration that had been transcode.

Solution

It was indeed the PEM passphrase on my private SSL key that was causing the problem. Apache needs it entering on startup, so it was hanging, kind of half running. I've taken the encryption off of the key and now it boots up fine. Thank you very much!!!

That's the main (and only) loop in main() after parse_options() has returned. How are you using ffmpeg - command line, API?
