    \n
  1. Before embarking on issue, Check is there any similar ticket which is working in team<\/u>\n
      \n
    1. – Search with a keywords(like signature, trickplay…) in Jira to know if any similar issue.<\/li>\n
    2. – Search Few keywords in logs to confirm it’s not AAMP issue
      grep -inr “OCDM could not be instantiated|AAMP_BUILD_INFO|aamp_tune|TELEMETRY_GATEWAY_PACKET_LOSS:100”\n<\/li>\n<\/ol>\n<\/li>\n
    3. If stack trace doesn’t have symbols then use Google Breakpad<\/a> to get manual stack trace<\/u>.\n
        \n
      1. – Try to search for the latest occurrence of the crash trace from crash portal.<\/li>\n<\/ol>\n<\/li>\n
      2. For crash issues<\/u>:\n
          \n
        1. Always check for the latest occurrence from the crash portal.<\/li>\n
        2. \n

          Always check WPE framework log around the crash time and see if there is any abnormality with ocdm plugin around the time. <\/p>\n<\/li>\n<\/ol>\n<\/li>\n

        3. For any playback related issues always ensure the following<\/u>.\n
            \n
          1. Whether Manifest download is successful.<\/li>\n
          2. Submanifest (HLS) download is successful.<\/li>\n
          3. Fragment download is successful.<\/li>\n
          4. Ensure License is acquired from the licensing server.<\/li>\n
          5. Ensure the pipeline is constructed successfully.<\/li>\n
          6. Ensure the pipeline received the first video segment from the callback. <\/li>\n<\/ol>\n<\/li>\n
          7. TDK related issues<\/u>\n
              \n
            1. Instead of bringing up TDK setup, we can run directly with aampcli binary to reproduce issue.<\/li>\n<\/ol>\n<\/li>\n
            2. For any config mismatch or not reflected issues from fog or aamp<\/u>.\n
                \n
              1. Compare the automation logs and box logs to find any mismatch.<\/li>\n
              2. Check the latest codebase if the variables are present.<\/li>\n<\/ol>\n<\/li>\n
              3. For any playback tune failures during STB standby mode or when UI connection is disconnected<\/u>.\n
                  \n
                1. Check why main UI application is sending the tune request.<\/li>\n
                2. Request main UI application team to have a look, as tune during standby or disconnected state is an invalid scenario.<\/li>\n<\/ol>\n<\/li>\n
                3. HTTP <\/u>proxy feature is targeted for third party application vendors who don’t support IPv6 addressing right now. To tackle v6 addressing issue, vendors will be using a 6to4 proxy to route their traffic<\/u>.<\/span>    <\/span>\n
                    \n
                  1. Don’t use RFC\/aamp.cfg to configure http-proxy for IP_Linear playback.<\/span><\/li>\n<\/ol>\n<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
