ffmpeg specify stream by handler_name
13 avril 2017, par KajunaI’ve got a file with these streams
Stream #0:0(eng): Video: h264 (High) (avc1 / 0x31637661), yuvj420p(pc, bt709), 1920x1080 [SAR 1:1 DAR 16:9], 45315 kb/s, 59.94 fps, 59.94 tbr, 60k tbn, 119.88 tbc (default)

I can map it with -map 0:3, but some files have that same Stream in a different position, like this :
Stream #0:0(eng): Video: h264 (High) (avc1 / 0x31637661), yuvj420p(pc, bt709), 1920x1080 [SAR 1:1 DAR 16:9], 60013 kb/s, 90 fps, 90 tbr, 90k tbn, 180 tbc (default)

handler_name : GoPro SOSHow can I make sure I’m selecting the right one ? I’ve tried with -map 0:m:handler_name :" GoPro MET" and things like that, but I’m always getting an error :
Stream map ’0:m:handler_name:GoPro_MET’ matches no streams.
Note that I had never used ffmpeg before and might be missing something obvious.
Thanks !

ffmpeg encoded mp4 won't play in safari, works in chrome & ff
16 avril 2017, par Mark Kahnlike the title says, I’m encoding a video from ffmpeg and it plays fine in chrome & ff but not safari. Anyone know why, what to try, etc ?
I followed the advice in this thread to no avail.
ffmpeg command :
ffmpeg -f lavfi -i color=$1 -i $2 -vcodec libx264 -pix_fmt yuv420p -filter_complex "[0:v][1:v]scale2ref[c][v];[c][v]overlay=shortest=1[j];[j]scale=134:80" $3_120-3x.mp4
Most of that is just adding a background color to a video that has alpha transparency. The
-vcodec libx264 -pix_fmt yuv420p
piece seems to be what’s important (btw without that it doesn’t play in FF either).result of
