ffmpeg for android, out of memory on encoding h264
15 juin 2018, par Rafael LimaI’m getting an weird error when enconding a video with ffmpeg on android
Failed to inject frame into filter network: Out of memory
Althoug is a pretty objective error, I do believe this is some "generic message" for another problem, because the video I used for testing is 17MB and less than 11 seconds length and I’ve sucessfully tested with videos bigger than 200MB and longer than 5min
This problem happens to
any videovertical videos recorded on my phone (the videos were recorded and play fine on my phone but i cant reencode them... other video h264 were encoded fine on same phone)this is ffmpeg output

Error reinitializing filters!
Failed to inject frame into filter network: Out of memory
Error while processing the decoded data for stream #0:0
Conversion failed!=====================UPDATE===================
I re-run the command with
-v 9 -loglevel 99
and got paste the log file at :If someone have real good expertise at ffmpeg i would apreciate very much the help
=====================UPDATE 2=================
I made more tests and the problem happens only when i record the video with my phone at vertical (other videos in vertical work and videos from my phone in horizontal also work)
==================UPDATE 3====================
I detected the problem happens to ANY video with theMetadata:
rotate : 90 (or any value)It was suggested to use
-noautorotate
as workaround and it WORKDED, but this implies in tons of other complications ex :-if i decide to apply any filter to the video, it will be applied to the horizontal version but the video will be played at vertical producing a totally different effect
ex : https://i.stack.imgur.com/R3jXJ.jpg (at this photo the drawtext filter should be placed at bottom line with horizontal text, but as ffmpeg can’t handle the orientation it is missplaced and rotated at runtime producing this vertical message)
-I checked and if I set
-metadata:s:v:0 rotate=
while enconding it has no effect ex :ffmpeg -i input.mp4 -c copy -metadata:s:v:0 rotate= output.mp4
will remove the rotate metadata and produce a non rotated videoBUT
ffmpeg -i input.mp4 -c:v libx264 -metadata:s:v:0 rotate= output.mp4
will keep the metadata and the produced video will be played rotated (this behavior was also noticed on the official ffmpeg 4.0 binaries for windows available at ffmpeg website)I’M STILL LOOKING FOR A BETTER SOLUTION, THANKS FOR THE HELP

ffmpeg Error initializing output stream 0:0 — Error while opening encoder for output stream
23 juin 2018, par gufidownI am a newbie in terms of video processing in general and ffmpeg in particular. So this might be a real beginner’s question.
I am trying to extract frames from an avi. This is the command :
ffmpeg.exe -i 123.avi -vf select='gt(scene\,0.4)',scale=1920:-1,tile=6x3 -frames:v 1 456.jpg
