lavfi: avfilter_graph_request_oldest: request a frame again before returning. With min_samples, if a frame arrives but is too small, it clears frame_wanted_out. In most cases, the destination filter would be activated again later because of frame_wanted_out on its own outputs, but not sinks. avfilter_graph_request_oldest() is doing the work of the sink itself, and is therefore allowed to use frame_blocked_in. > http://git.videolan.org/gitweb.cgi/ffmpeg.git/?a=commit;h=373f21a91126d052cd310d675f43f548a407649e --- libavfilter/avfiltergraph.c | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) diff --git a/libavfilter/avfiltergraph.c b/libavfilter/avfiltergraph.c index 6b5a6f3..cb5d618 100644 --- a/libavfilter/avfiltergraph.c +++ b/libavfilter/avfiltergraph.c @@ -1407,7 +1407,11 @@ int avfilter_graph_request_oldest(AVFilterGraph *graph) frame_count = oldest->frame_count_out; while (frame_count == oldest->frame_count_out) { r = ff_filter_graph_run_once(graph); - if (r < 0) + if (r == AVERROR(EAGAIN) && + !oldest->frame_wanted_out && !oldest->frame_blocked_in && + !oldest->status_in) + ff_request_frame(oldest); + else if (r < 0) return r; } return 0; _______________________________________________ ffmpeg-cvslog mailing list ffmpeg-cvslog@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-cvslog
