This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...) -

Capturing stream that has multiple frames
28 mai 2021, par cheese5505I'm trying to capture a stream that has multiple "frames" (not sure that's what you would call it but it has multiple 5 second streams inside of it) with FFmpeg and saving to file. When I put it into Quicktime player and play it works fine, however when I put it into FFmpeg and review the final file it seems that the audio and video are out of sync and the video frequently stops. I think this may be because it is stopping to switch to the new 5 second video but i'm not sure. This is the command I am using :



ffmpeg \
 -v 9 \
 -loglevel 99 \
 -y \
 -re \
 -hwaccel auto \
 -threads 4 \
 -user-agent "Mozilla/5.0 (iPhone; U; CPU iPhone OS 3_0 like Mac OS X; en-us) AppleWebKit/528.18 (KHTML, like Gecko) Version/4.0 Mobile/7A341 Safari/528.16" \
 -i "url here" \
 -ac 2 \
 -strict -2 \
 -c:a aac \
 test.mov




In the FFmpeg log this frequently happens :



frame= 242 fps=102 q=29.0 size= 252kB time=00:00:06.33 bitrate= 325.9kbits/

Any ideas how I could smooth out the final file would be greatly appreciated.

Can I programmatically insert audio from a Webm file into another Webm file ?
18 janvier 2016, par andyI have two WebM files, both have video and audio.
I want to insert the audio from one WebM file into the other so that the final WebM file has two audio "streams" playing simultaneously with the video.
Is it possible to achieve this programatically ? Preferably with Ruby, or if not with a command line interface, maybe ffmpeg ?
