#4071: Playing a live rtmp stream fails (regression) -------------------------------------+------------------------------------- Reporter: pickles | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: rtmp | Blocked By: regression | Reproduced by developer: 0 Blocking: | Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: The latest master ffmpeg (compiled without librtmp) doesn't automatically detect a live rtmp stream that is streamed from adobe media server, so it quits with the following error: Server error: Method not found (getStreamLength). This indicates that ffmpeg is treating it as a VOD stream, rather than a live stream.

Checking with git bisect yields that: 324b23dde1bc8638959eb32419c95a93906db272 is the first bad commit So I assume this is a regression since 324b23d. This rtmp server ''does'' work if you force {{{ -f flv -rtmp_live live }}} but this was not necessary prior to 324b23d. My understanding is that the default 'any' autodetection behaviour for rtmp_live should automatically try a live stream, and then fall back to VOD if no live stream exists. It seems that the default 'any' autodetection setting for rtmp_live isn't working properly here. -- Ticket URL: <https://trac.ffmpeg.org/ticket/4071> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
