I wrote tests to + verify support for the functionality, and found that, in push mode, + `GST_EVENT_SEGMENT` events pushed to the demuxer by the upstream `filesrc` + element would be forwarded to the decoder without modification, resulting in + an internal data streaming error. With this patch, tests work in both push and + pull mode. + This patch solves the problem by disabling the forwarding of + `GST_EVENT_SEGMENT` events downstream (an initial `GST_EVENT_SEGMENT` event is + still pushed downstream by the demuxer). It's possible there's a better way to + do this, but, having looked at how a few different `gstreamer` demuxers deal + with `GST_EVENT_SEGMENT` events, it seems like the processing is somewhat + specific to the demuxer implementation, whereas `gst-libav` has one general way + of handling the situation for any `ffmpeg` demuxer. Perhaps there's a better + way to solve this using the `ffmpeg` API to take advantage of specific demuxer + details.
