Hi,
I am transcoding a h264 DVB-T stream but I am not satisfied with the
results. The picture looks like "interlaced" on fast moving scenes.
Here I posted (sorry for long post) some ffprobe data of the original
(input) stream and output stream. What are my options to get a better
picture?
I am transcoding with ffserver, with this config:
<Stream stream001.mkv>
Feed stream001.ffm
NoLoop
Format matroska
VideoCodec libx264
VideoFrameRate 25
VideoBitRate 1524
VideoSize 720x576
AVOptionVideo preset ultrafast
AVOptionVideo tune zerolatency
AVOptionVideo flags +global_header
AVOptionVideo crf 26
AVOptionVideo me_range 16
AVOptionVideo qdiff 4
AVOptionVideo qmin 10
AVOptionVideo qmax 51
AudioCodec aac
Strict -2
