Workaround for webbrowsers buffering live webm streams and introducing a delay (how to play live webm stream)
8 juillet 2014, par CoryGI have webm streams coming from an ffserver (16 streams), managed to get all 16 to load at once within a browser, but whether I am playing just one or 16 there is a delay of 3-5 seconds introduced due to either buffering or the handshake plus some kind of compensation to try and sync the timestamps by the browser itself, which leads to my question :
Is it possible to force a browser playing a webm stream via HTML5’s video tag (I only really care about Chrome, but it’s happening in Firefox too) to play from the actual most recent frame (clients and servers share a common NTP server over the LAN, so they are guaranteed to be synced, if that is a factor) as opposed to maintaining a buffer of several seconds and playing from the start of that buffer ?

ffmpeg scale logo size according to video size
5 août 2017, par TeddybugsI have a ffmpeg command which is working fine to inject 2 image on the top left and bottom right of the video.
ffmpeg -i ori.mp4 -y -i 1.png -i 2.png -filter_complex \
"[0:v][1:v]overlay=20:20[bkg]; \
[bkg][2:v]overlay=(main_w-overlay_w)-20:(main_h-overlay_h)-20" \
-codec:v libx264 -crf 18 -preset slow -pix_fmt yuv420p \
-c:a aac -strict -2 out1.mp4this command working fine with video that has large size like 720x480, however when the input video size is 320x240 size, it will overlay half of the video size.
1.png size is : 160x100
2.png size is : 341x44
any idea how to combine the scale2ref into above command ?
been trying solution from this link so far no luck.
update 1 : i found this command from here
ffmpeg -i ori.mp4 -y -i 1.png \
-filter_complex "[1:v][0:v]scale2ref=iw*0.25:-1[logo1][base]; \
[base][logo1]overlay=20:20[v]" -map [v] -map 0:a \
-codec:v libx264 -crf 18 -preset slow -pix_fmt yuv420p \
-c:a aac -strict -2 out2.mp4that command work fine to get one image to scale.
update 2 :
ffmpeg -i ori.mp4 -y -i 1.png -i 2.png \
-filter_complex "[1:v][0:v]scale2ref=iw*0.25:-1[logo1][base];\
[base][logo1]overlay=20:20[v];[2:v][0:v]scale2ref=iw*0.30:-1[logo2][base2];\
[base2][logo2]overlay=(main_w-overlay_w)-20:(main_h-overlay_h)-20[v]" \
-map [v] -map 0:a -codec:v libx264 -crf 18 -preset slow -pix_fmt yuv420p \
-c:a aac -strict -2 out4.mp4tried above, nothing work. got error like this
Filter overlay has an unconnected output
any help would be great
