FFMPEG audio decoding
8 juillet 2012, par Nitin GoyalI have used the avcodec_decode_audio3 function to decode the AMR content in the frame order.
I get 640 bytes output for each frame, with sample format being float and I have saved the output as a raw output file.
Now, I want to validate this output content. But I can't play it in any player as it does not have any header or media info. And I am not able to find any command in ffmpeg which gives me raw audio output.
Now, if want to re-encode that raw output content in FFMPEG, what would be the input format I need to give.
Can anybody give some suggestion on this ?

Is it possible to extract pngs with transparency from flv files using ffmpeg ?
1er octobre 2012, par Aakash GoyalI am building a video editor capable of creating composite videos. I need to convert videos to frames during exporting and need to maintain the transparency while doing so. ffmpeg does a pretty good job if I give an avi file as input ie it outputs frames with transparency. But in case of a flv file it give out frames with black color instead of transparent. Is there any way to get frames from flv with transparency ?
I am using "ffmpeg -i video.avi -r 25 %d.png" command.

Playing back video one frame at a time and saving a bitmap on android
7 septembre 2017, par TimmothI’m trying to achieve frame by frame playback of mp4 videos on Android with the ability of capturing and saving a chosen frame to an external storage device.
I have used VideoView and MediaController to playback a video and MediaMetadataRetriever to retrieve and save a frame as a bitmap however this solution does not give me the ability to step through the video one frame at a time nor does it allow me the accuracy i need of capturing a specific frame.
I have been reading up on how to cross compile FFMPEG for android and write a wrapper to give me a much larger range of video capabilities as i believe this is a viable route to go down. Unfortunately there is not much information out there on getting FFMPEG working on Android, and i couldn’t find anything helpful from the last few years.
My questions are
1) Am i missing something and does the android framework give this granular control over video playback ?2) Is it possible to use FFMPEG to playback a video frame by frame in a android application ?
3) Does anyone have any resource on compiling and using a recent version of FFMPEG on android 7 ?
