Les vidéos

21 avril 2011, par kent1

Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

Specifying FFMPEG in the requirements section of 'buildozer.spec' causing [libavformat/network.o] Error 1

18 juillet 2022, par GJ78
My question relates to how to mitigate an ffmpeg requirement listed in a buildozer.spec that is causing compile errors using buildozer.





GOAL :





Using buildozer to ensure FFMPEG can be embedded within a small Kivy app so i can utilise youtube_dl functionality on my android phone.





THE ISSUE :
Specifying FFMPEG in the requirements section of 'buildozer.spec' causes the following error message :

common.mak:60 : recipe for target 'libavformat/network.o' failed

make : [libavformat/network.o] Error 1

make : Waiting for unfinished jobs...





What have I done to resolve myself :

1. Ensured LOG LEVEL 2 is specified.




1. Upgraded cython from Version 21 to 27. Then downgraded to 25, then 21 then 20 to see if this resolved anything. It didn't.
2. In BUILDOZER.SPEC, switched between Android NDK crystax-ndk-10.3.2 and android-ndk-r16b. (Note have reverted back to Crystax 10.3.2) in my NDK PATH.
3. In BUILDOZER.SPEC, changed android.api from 19 to 15 (just to see if this has any positive effects).
4. executed : rm -Rf .buildozer between each compiling attempt.
5. Part extract of Buildozer.log :

7. Lastly, when I remove ffmpeg from requirements in buildozer.spec, the .APK compiles successfully and i can deploy it on to my phone with the KIVY GUI. Obviously, ffmpeg functionality is not present.




Current Environment Specs :




1. Running Linux Mint 17.2 as a Virtual Box VM
2. Buildozer Version : 0.35dev
3. Cython Version : 0.25




Any advice would be greatly appreciated.





Lastly, if there is no obvious solution via buildozer, do i need to compile ffmpeg for Android separately and somehow include this somewhere in the buildozer spec file to prevent this error message ?





Thanks in advance.

Can't play at a good framerate with JavaAV

31 mars 2017, par TW2

I have a problem in framerate when I use JavaAV (which use JavaCPP + ffmpeg). When I set my framerate as mentionned at DemuxerExample.java, the frame change each 47000ms which is too long and false. It’s better when I set 1000 / demuxer.getFrameRate() * 1000 ( 47ms) but it’s also false. I can’t have a good framerate. Here is my player class :

FFMPEG - adding a nullsrc causes my script to report "1000 duplicate frames"

14 juin 2020, par rossmcm

I'm trying to add coloured rectangle highlights to a video, appearing at different locations and times. The highlights are on a 6x6 grid of 320x180 rectangles.

Originally I didn't have the nullsrc=size=1920x1080 thinking that it would start with an empty image, but it seems that that causes it to make assumptions about where the input is coming from. So I added the nullsrc=size=1920x1080 to start with a transparent 1920x1080 image but this command returns a warning that 1000 duplicate frames have been produced and it keeps going past the end of the input video with no signs of stopping.

ffmpeg -y \       &#xA;  -i "Input.mp4" \           &#xA;  -filter_complex \ &#xA; "nullsrc=size=1920x1080, drawbox=x=(3-1)*320:y=(3-1)*180:w=320:h=180:t=7:c=cyan,   fade=in:st=10:d=1:alpha=1, fade=out:st=40:d=1:alpha=1[tmp1]; \&#xA;  nullsrc=size=1920x1080, drawbox=x=(4-1)*320:y=(4-1)*180:w=320:h=180:t=7:c=blue,   fade=in:st=20:d=1:alpha=1, fade=out:st=50:d=1:alpha=1[tmp2]; \&#xA;  nullsrc=size=1920x1080, drawbox=x=(5-1)*320:y=(5-1)*180:w=320:h=180:t=7:c=green,  fade=in:st=30:d=1:alpha=1, fade=out:st=60:d=1:alpha=1[tmp3]; \&#xA;  nullsrc=size=1920x1080, drawbox=x=(6-1)*320:y=(6-1)*180:w=320:h=180:t=7:c=yellow, fade=in:st=40:d=1:alpha=1, fade=out:st=70:d=1:alpha=1[tmp4]; \&#xA;  [tmp1][tmp2] overlay=0:0[ovr1]; \ &#xA;  [tmp3][tmp4] overlay=0:0[ovr2]; \ &#xA;  [ovr1][ovr2] overlay=0:0[boxes]; \ &#xA;  [0:v][boxes] overlay=0:0" \        &#xA;  "Output.mp4"&#xA;
