Comment (by rbarajas):
We tested the attached patch and the issue still occurred. We contacted
Adobe again and after a lot of testing and tracing we figured out that FMS
requires the reset to happen at or close to 4,000,000,000. The fix we
tried and confirmed it works as expected is the following.
{{{
if (rt->bytes_read - rt->last_bytes_read > rt->client_report_size) {
av_log(s, AV_LOG_DEBUG, "Sending bytes read report\n");
if ((ret = gen_bytes_read(s, rt, rpkt.timestamp + 1)) < 0)
return ret;
if (rt->bytes_read > 4000000000)
rt->bytes_read = 0;
rt->last_bytes_read = rt->bytes_read;
}
}}}
