Use ffmpeg to stream an updating progress-bar
24 juin 2020, par FalkIs there a way to stream a filling progress-bar showing a percentage written in either a (e.g. txt) file or mysql db that updates often ? Ideally streaming to obs or straight to the platform/stream (such as twitch) ?


I thought about using the text function, something like this :

-vf "drawtext=fontsize=40:fontfile=FreeSerif.ttf:textfile=/path/livetext.txt:x=(w-text_w)/2:y=(h-text_h)/2:reload=1"

Blender VSE Audio out-of-sync when animation (video) is rendered
21 août 2021, par Siddhant ShenoyOk, so I found out that Blender has this really cool video-editing interface and I was beginning to love it. Until, I created this awesome project composition and when I exported the animation as a video file, the audio was out of sync :(.



Actual Problem



Audio is in-sync with video when the animation is played in Blender but is out-of-sync in the rendered video.



Solutions I tried out and failed



- 

- I used the 'Audio-Sync' option in the sequencer but that made no difference.
-
Then I thought that my scene audio frequency might have been an issue since it was initially 48kHz and my videos were at 24kHz, so I changed the scene audio frequency to 24kHz, this still failed to solve the issue.
-
Initially, I was combining videos with different frame rates and thought that might have been an issue (although animation played as expected in Blender), so I recreated the source videos to ensure all videos I was using in my project had the same frame rate, but this also did not work.
- Someone online suggested exporting the video and audio separately and then combining them using a command-line tool like FFMPEG, this also failed.











What's really frustrating



- 

-
This lag (audio is a few frames ahead of the video) is noticeable only in longer videos (>12 mins, my video is 1 hr long) suggesting a very small rendered rate difference between the video and the audio.
-
Also, note that the animation plays absolutely fine in Blender, so all I could figure out was that this was a rendering issue.







So if anyone figured this out please let me know. I am a noob in video/audio codecs so please forgive me if I used some incorrect nomenclature above.

How can I record video with FFMPEG in ISO BMFF format ready for Media Source Extensions ?
17 novembre 2015, par MattI’m trying to record video using ffmpeg and then play it back on a player using MSE. Here’s the script I’m using :
ffmpeg -i /dev/video0 -c:v libx264 -profile:v baseline -level:v 13 -g 250 -r 25 -keyint_min 250 -strict experimental -pix_fmt yuv420p -movflags frag_keyframe+empty_moov -b:a 96k sintel.mp4
This works except for the fact that there is an mfra box at the end of the video file, which I believe is not supported by MSE. How can I remove this mfra box ?
