ffmpeg-python Unable to open .srt, .vtt files. Error initializing filter 'subtitles' with args ... Error initializing complex filters
3 novembre 2022, par Batuhan YılmazI'm trying to build a web app where users can upload a video file and a transcript as .srt or .vtt file to get a video with subtitles. But keep getting an error with the subtitles.

Here's my code :

Stream is not appearing on youtube
1er novembre 2022, par AMRITESH GUPTAI am trying to stream a captured stream to youtube live through FFmpeg, but the stream is not appearing on youtube. I tried giving input from an mp4 file, and it worked perfectly but providing input as a buffer through stdin gives nothing.


FFmpeg command


ffmpeg -rtbufsize 100M -report -i - -v error -c:v libx264 -preset veryfast -tune zerolatency -g:v 60 -c:a aac -strict -2 -ar 44100 -b:a 64k -y -use_wallclock_as_timestamps 1 -async 1 -f flv ${youtubeURL}


I used
-report
for generating a log report, and I couldn't find anything wrong with it.

Here is snippet of log file
