Constant Crashing After 1-2 Days of Streaming in BaseSenderReport.swift #46

Open vitkuzmenko opened 2 weeks ago

vitkuzmenko commented 2 weeks ago

After streaming continuously for 1-2 days, the app begins to crash frequently. Initial investigation suggests that the issue may be related to Thread 3.

BaseSenderReport might play a role in this behavior. When I commented out this section in RtspSender.swift, streaming works perfectly.

if (try self.senderReport?.update(rtpFrame: frame) == true) {
    // Convert bytes to bits (4 is the TCP header length)
    let reportSize = isTcp ? RtpConstants.REPORT_PACKET_LENGTH + 4 : RtpConstants.REPORT_PACKET_LENGTH
    self.bitrateManager.calculateBitrate(size: Int64(reportSize) * 8)
    if isEnableLogs {
        print("wrote report")
    }
}

After streaming continuously for 1-2 days, the app begins to crash frequently. Initial investigation suggests that the issue may be related to Thread 3.

BaseSenderReport might play a role in this behavior. When I commented out this section in RtspSender.swift, streaming works perfectly.

if (try self.senderReport?.update(rtpFrame: frame) == true) {
    // Convert bytes to bits (4 is the TCP header length)
    let reportSize = isTcp ? RtpConstants.REPORT_PACKET_LENGTH + 4 : RtpConstants.REPORT_PACKET_LENGTH
    self.bitrateManager.calculateBitrate(size: Int64(reportSize) * 8)
    if isEnableLogs {
        print("wrote report")
    }
}
  • Could BaseSenderReport be causing memory or processing issues over extended streaming?
  • Is it safe to keep this code commented out, or does this impact the reliability of streaming reports?

Hello,

Thank you for the report. Comment it is safe depend of the server. Few servers need it but others servers don't need it. If you have an environment with only a server you can do it.
