Make sure that the fallback parametes for a given input are only used when that input is unconfigured. --- fftools/ffmpeg_filter.c | 24 +++++++++++++----------- 1 file changed, 13 insertions(+), 11 deletions(-) diff --git a/fftools/ffmpeg_filter.c b/fftools/ffmpeg_filter.c index 2c3e2a96f7..8eca0f2cae 100644 --- a/fftools/ffmpeg_filter.c +++ b/fftools/ffmpeg_filter.c @@ -1521,17 +1521,19 @@ int ifilter_send_eof(InputFilter *ifilter, int64_t pts, AVRational tb) if (ret < 0) return ret; } else { - // the filtergraph was never configured, use the fallback parameters - ifilter->format = ifp->fallback.format; - ifilter->sample_rate = ifp->fallback.sample_rate; - ifilter->width = ifp->fallback.width; - ifilter->height = ifp->fallback.height; - ifilter->sample_aspect_ratio = ifp->fallback.sample_aspect_ratio; - - ret = av_channel_layout_copy(&ifilter->ch_layout, - &ifp->fallback.ch_layout); - if (ret < 0) - return ret; + if (ifilter->format < 0) { + // the filtergraph was never configured, use the fallback parameters + ifilter->format = ifp->fallback.format; + ifilter->sample_rate = ifp->fallback.sample_rate; + ifilter->width = ifp->fallback.width; + ifilter->height = ifp->fallback.height; + ifilter->sample_aspect_ratio = ifp->fallback.sample_aspect_ratio; + + ret = av_channel_layout_copy(&ifilter->ch_layout, + &ifp->fallback.ch_layout); + if (ret < 0) + return ret; + } if (ifilter->format < 0 && (ifilter->type == AVMEDIA_TYPE_AUDIO || ifilter->type == AVMEDIA_TYPE_VIDEO)) { av_log(NULL, AV_LOG_ERROR, "Cannot determine format of input stream %d:%d after EOF\n", ifilter->ist->file_index, ifilter->ist->st->index); -- 2.39.2 _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-request@ffmpeg.org with subject "unsubscribe".
