Summary
This release includes another gas price monitoring fix to address additional cases where Ethereum JSON-RPC providers occassionally return really low gas prices for the eth_gasPrice RPC call, automatic replacements for pending transactions that timeout, fixes for broadcaster stream recording, support for downloading stream recordings as mp4 files as well as variety of other bug fixes and enhancements. We strongly recommend all orchestrator and transcoder operators to upgrade to this version to access this latest set of bug fixes and improvements.
In addition to the gas price monitoring fix and support for automatic replacements for pending transactions that timeout, a few additional configuration options are introduced to give node operators more control over gas prices and transactions:
-maxTransactionReplacements <INTEGER>can be used to specify the max number of times to replace a pending transaction that times out. The default value is 1.-txTimeout <DURATION>can be used to specify the timeout duration for a pending transaction after which a replacement transaction would be submitted. The default value is 5m.-minGasPrice <INTEGER>can be used to specify the minimum gas price (in wei) to use for transactions. The default is 1 gwei on mainnet.
More information about these new flags is accessible via livepeer -help.
The default value for the -maxTicketEV flag for broadcasters has been updated to 3000 gwei based on the default value of 1000 gwei for the -ticketEV flag for orchestrators which is safer for broadcasters. For more information on these default values, refer to the payment docs for video developers and the payment docs for video miners.
An experimental version of a deep neural network (DNN) based scene classification capability is mentioned in the changelog, but please note that while this is the first step towards enabling this capability on the network for video miners, this feature is NOT yet usable on the network today and is undergoing rapid development.
Thanks to everyone that submitted bug reports and assisted in testing!

Note: The Windows release was cut from a commit that was created after the v0.5.19 tagged commit because there was a Windows build process issue that needed to be fixed after the v0.5.19 commit. As a result, livepeer.exe -version will report 0.5.19-b6b17f1 instead of 0.5.19.
