Heavy pixelation when transcoding TS with subtitles
The transcoded file of some DVB-TS sources has heavy pixelation at some points. This only happends if the source has a subtitle PID as part of it's ES. I don't get the pixelation when using --no-spu when transcoding.
This is the simple command I use for transcoding:
vlc /tmp/sample1.mts --sout "#transcode{vcodec=h264,vb=640,scale=1,fps=25}:standard{access=file,mux=ts,dst="/tmp/out1.mts"}" --no-spu -vvv
Tested with Ubuntu v2.1.5 and latest GIT with same results.
I'm trying to record a short dump to upload a sample here so you can reproduce the problem.
Please, let me know if you need more information. Thanks in advance.
