## Static ffmpeg/ffprobe sourced from a registry image rather than curl'd from
## johnvansickle.com. That host has no CDN and regularly refuses or stalls
## connections from GitHub Actions runners, which burned 5 x 300s retries per
## build before failing. Registry pulls use the same transport as the base
## images and are cached by buildx. Pinned to the multi-arch manifest digest.

curl official documentation --retry-max-time total time initial transfer retry semantics

💡 Result:

The --retry-max-time option in curl is used to set a total time limit, in seconds, during which curl is permitted to perform retries [1][2]. Its semantics and interaction with other options are summarized below: Retry Timer Mechanics: The retry timer begins before the first transfer attempt [1][3]. The --retry-max-time value acts as a ceiling for the duration of the entire retry process [2][3]. Before starting any new retry attempt, curl checks if the elapsed time since the beginning of the initial attempt has exceeded this limit [4]. If the timer has reached or exceeded this limit, curl stops retrying and gives up [1][3]. Interaction with Transfer Duration: The --retry-max-time option only limits the time spent waiting for and initiating retries [2][3]. If a transfer attempt has already started and is currently in progress, it is permitted to complete even if its duration causes the total time to exceed the --retry-max-time limit [1][4]. To strictly limit the duration of each individual transfer attempt, you should use the --max-time option [5][1]. Inclusion of Wait Times: The retry timer includes both the time spent on actual transfer attempts and the time spent sleeping between attempts (e.g., due to the default exponential backoff or the --retry-delay option) [4]. Relationship with --retry: The --retry option defines the maximum number of times curl will retry a failed transfer [5][2]. The process will terminate when either the maximum number of retries defined by --retry is reached, or the duration defined by --retry-max-time has elapsed, whichever happens first [2]. If --retry-max-time is set to zero (the default), there is no time limit on retries [1][3].

Limit retry time for every curl download.

Add --retry-max-time 600 to the Piper archive, voice model, and metadata downloads. Keep --max-time 600 because it limits each transfer attempt; --retry-max-time limits the retry period. Without it, six attempts can allow one download to run for about 3,600 seconds.
