  • how to build ffmpeg with burn text on hls output while maintaining the aspect ratio

    26 février 2016, par Aameer

    My objective is to burn a text(watermark) at a particular time range on the outputed hls video, I also have to change just the height and maintain the aspect ratio which I am able to do but the burning in text part is not working. First the ffmpeg I used is for 14.04 ubuntu, details are here. I don’t think this build supports subtitle (docs) filter which I could have used for my purpose as described here. when i enter ffmpeg into the terminal this is the output

(ffmpeg)aameer@falcon:~/Documents/projects/ffmpeg$ ./ffmpeg -threads 4 -i "input_sintel_trailer_720p.mp4" -profile:v baseline -level 4.0 -vf scale="trunc(360*a/2)*2:360, subtitles='subtitle.srt'"  -start_number 0 -hls_time 10 -hls_list_size 0 -f hls videos/4444/index_4444_360_.m3u8

    but got an error

    Could not write header for output file #0 (incorrect codec parameters ?): No such file or directory

    Any help in this regard would be appreciated. I don’t have much experience with compiling , otherwise would have done with support for libass as mentioned in the documentation here
