i think openmax at least works a little better, i'll do some tests now AMD Polaris GPU's don't do b-frames so we need to be able to tweak / patch ffmpeg to use base profile etc ffmpeg h264_vaapi assumes vaapi can do high profile. I have trawled the internet but to no avail. it compiles ok but the dvb_teletext decoder / encoder is not included in the list of codecs. I am building version 3.4.1 with the -enable7libzvbi flag I am building ffmpeg with support for zvbi_teletext can you help me create a watermark with text transparency? overlay=enable='lte(t,30)' doesnt work 39 frames left in the queue on closing is there someway to add watermark only in the first 2 minutes of the video? I just updated for newest ffmpeg and worked hey there :) I am trying to set watermark with this code in manjaro updated works but in ubuntu 16.04 it gives error and the out.mp4 is empity so i converted the mp4 to mkv and tried the same thing but no difference so change output from mp4 to mkv and you think it will work? well if i could loop say 10 times that would probably work - any suggestion how i can do 10 times? or a suggestion on what is up with stream_loop ? if you want an infinite loop then you're pretty much stuck with stream_loop ultimately i want infinite loop but was just testing with 3 there are a bunch of different ways to do this though presumably not because that's not a thing do you mean like cat out.mp4 out.mp4 out.mp4 | ffmpeg -y -an -i -c copy junk.mp4 ? why not just cat the video stream over and over if you are not encoding so video is like 10 seconds long but when i add stream_loop to the same command it is takes over 3 minutes. hi - i am seeing something odd when I use stream_loop - anyone around want to take a stab at it? Does -threads 1 disable filter slice threading I request op assistance in the channel for the obvious problem I can see in log file that i get cur_dts is invalid (this is harmless if it occurs once at the start per stream) Any clue why my FFMPEG timestamp is faster than it should be? Seconds are going too fast if i check the time played but in practice I would probably just remux and see how players reflect the difference in size between canvas and video and then for DVB and DVD I think we have an encoder? in theory you can get the output of the DVB/DVD/blu-ray subpictures as a video track and scale it I'm not sure if rescaling or just leaving them as-is and hoping the players do things so that it matches is better Is it possible to resize picture (DVD) subtitles? I'm resizing the video and I'd rather not burn them in or convert to text, but I'll do that if I have to. Next message (by thread): ffmpeg-devel.log.20180128.
