Faster Thumbnail/Image Extraction from Video using FFMPEG ?
27 août 2012, par mirroredAbstractionI am using this command to extract a series of images from a video to express them as a visual time-frame of the video.
ffmpeg -i inputfile.mp4 -r 1 -t 12 image-%d.jpeg
Most of my videos are in mp4 format. I am able to extract the images successfully but the time taken for extraction is too long.
Is there any way I could reduce the time for image extraction ?
EDIT : It is taking me 60 secs to get 8 thumbnails from a 15 sec long video encoded in MP4 format, I am doing this operation on my Galaxy Nexus(Android Phone) is there any way to improve the speed of operation, ideally I want it be less than 10secs.

Does MediaCodec truncate incoming packets for decoding ?
15 octobre 2013, par mathieujofisI'm using
MediaCodec
to decode h264 packets that were encoded with ffmpeg. When I decode with ffmpeg, the frames display fine. However, when I decode with theMediaCodec
hardware decoder I sometimes get black bars that show up in the middle of the frame. This only happens if the encoding bitrate is set high enough (say upwards of 4000000) so that any givenAVPacket
size becomes above 95000 or so. It seems likeMediaCodec
(or the underlying decoder) is truncating the frames. Unfortunately, I need the quality so the bitrate can't be turned down. I've verified that the frames aren't being truncated elsewhere, and I've tried settingMediaFormat.KEY_MAX_INPUT_SIZE
to something higher.Has anyone ran into this issue or know of a way I can work around it ?
I've attached an image of random pixels that I rendered in OpenGL and then decoded on my Galaxy S4.

Android Camera App Performance Increases [closed]
5 novembre 2012, par SpentakI am writing a video recording app but am finding it quite impossible to match the frames per second that are on the native Android device video camera app (on Samsung Galaxy sIII). On the native app I can record at 1920x1080 with effects on at an amazing FPS (not sure exactly what it is but it looks like 25+ fps).
In my app on the sIII my video recording is incredibly unstable and choppy even at 640x480. My FPS drops to 7 when recording at 640x480. When I add effects the FPS drops to 3-5.
Can someone help me figure out how to get an FPS that is equal to the native Android camera app (specifically on the sIII) ?
At this point I'm not sure where to optimize.
And for reference, I am just doing the standard video recording stuff as in :
How can I capture a video recording on Android ?Thanks !
