mpegvideo : allocate sufficiently large scratch buffer for interlaced vid
16 mai 2013, par Jindrich Makovickampegvideo : allocate sufficiently large scratch buffer for interlaced vid
MPV_decode_mb_internal needs 3 * 16 * linesize bytes of scratch buffer
For interlaced content, linesize is multiplied by two after the allocation
of the scratch buffer, and the dest_cr pointer ends past the buffer.This patch makes ff_mpv_frame_size_alloc allocate a total of
(aligned line_size) * 2 * 16 * 3 bytes, which suffices even for the
interlaced case.CC:libav-stable@libav.org

Video Compression in Android
4 avril 2017, par MontyI want to compress and decompress a video File in Android.I tried with zipping and unzipping it and it was successful :)
But what I need is compress and decompress it like how it happens in Watsapp. Also, zipping could only compress the video by 2.5% .
I also tried looking for FFmpeg in android, but I was not able to get though it
Could anyone provide and good reference/help/CODE EXAMPLE where a .mp4 file could be easily compressed ?
Thanks !!
