It was an error in your second command given, where you had written: "whats strange is this command does work with text overlay". I'm now assuming this is the command you wish to get working: > dvgrab -format dv1 - | \ > /home/<me>/Downloads/ffmpeg-git-20180920-64bit-static/ffmpeg \ > -deinterlace -f dv -i - -f flv -y \ > -vf > [in]drawtext="fontfile=/home/<me>/packages/Fonts/verdana.ttf:textfile=/home/<me>/screentext.txt:fontcolor=white:fontsize=20:x=30:y=30:reload=1"[out] > \ > -codec:v libx264 -preset slow -aspect 16:9 -s 320x180 -b:v 1500k -maxrate > 500k -bufsize 1000k -vf scale=-1:240 -threads 0 > -framerate 15 -qscale:v 20 -codec:a aac -b:a 64k -af aformat=s16:44100 > rtmp://<ip-address>/<name-nginx>" Correct? One thing to always first do when debugging is to e.g. change the output to a file, such as output.mkv or output.mp4, and see whether the desired effect is missing there as well. Your issue is likely: You're passing "-vf" twice. Only one of them is taken into consideration! (Perhaps ffmpeg should warn, but it isn't implemented to do so right now.) That's why your drawfile is probably ignored. "ffmpeg -loglevel debug" would show the actually used filter chains. (Even without the loglevel, it should be obvious what is missing.) If you want several filters, you need to combine them to a chain: $ -vf "drawtext=...,scale=..." I don't think "-vf" actually handles "[in]" and "[out]" - you're not even telling it what "[in]" is, so this "-vf" option is obviously just being ignored. Additional remarks: "-deinterlace" inserts a deinterlace filter somewhere. I'm not sure about the cross-effect on "-vf", so better to explicitly insert a particular deinterlace filter in your chain. I don't know what the effect of "-vf scale=-1:240 -s 320x180" is. I believe the latter argument inserts (another) scale filter at the end. Why not just "-vf scale=-1:180" and drop "-s ..."?? You need to think about what you are trying to achieve, and best put all into one filter chain, e.g.: $ ffmpeg -i input -vf "yadif=...,drawtext=fontfile=/home/<me>/packages/Fonts/verdana.ttf:textfile=/home/<me>/screentext.txt:fontcolor=white:fontsize=20:x=30:y=30:reload=1,scale=-1:180" [...] Cheers, Moritz _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
