is it possible to play h264-mpegts format in ios ?
11 octobre 2012, par jAckOdEServer transcodes the video to the h264/aac, and send video data to client simultaneously. To play and save the video data at the same time, I use mpegts as the container format, but the problem is that ios MediaPlayer can not play mpegts file.
Google said that i can used ios-build of ffmpeg to do the task, but it seem to be an overkill. is there any other ways to play mpegts in iphone using just iOS SDK ?

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.
