FFMPEG conversion error from MKV to MP4 using libfdk_aac codec
23 août 2014, par Charlie BrownThe purpose of doing this is because my "Smart" samsung TV doesn’t play MKV files.
This thread mentions that there is no need for video conversion, just changing the container might suffice. After reading multiple threads on how to change the container of MKV to MP4, I downloaded and compiled the FFMPEG with libfdk_aac support from here. I tried converting a sample MKV file using this command :
ffmpeg -i "C:\VideoTest\Sample1.mkv" -c:v copy -c:a libfdk_aac -b:a 384k "C:\VideoTest\Sample2.mp4"
but getting the following errors (copied from command prompt) :
[hevc @ 0000000000308ae0] Could not find ref with POC 113

But this screws up the video quality and I start seeing some bad pixelated patches during the playback.
Any help would be appreciated.
Just an FYI : I got this far by reading blogs and posts. I have 0 knowledge about video conversion.

ffmpeg command failed
25 octobre 2015, par Asad kamranI am experimenting FFMPEG command to convert any video format to mp4.
Server admin execute the below command created by me and show me the errors :
ffmpeg -ss 00:03:00 -i /video/1444107854.mov -c:v libx264 /video/player/1444107854.mp4 -vframes 1 /video/thumb/1444107854.jpg
This is error :
[aac @ 0x2b845a0] The encoder ’aac’ is experimental but experimental
codecs are not enabled, add ’-strict -2’ if you want to use it.how can i avoid this error and also experimental codec, so can any one let me know what can be best codec if i explicitly specify it.
my ffmpeg and server are as follow :
ffmpeg version N-75903-g14573b9 Copyright (c) 2000-2015 the FFmpeg
developers built with gcc 4.4.7 (GCC) 20120313 (Red Hat 4.4.7-16)EDIT 1 :
I change the command a bit and add -c:a copy to copy audio stream as it is but still no hope :New command :
ffmpeg -ss 00:03:00 -i /video/1444107854.mov -c:v libx264 -c:a copy /video/player/1444107854.mp4 -vframes 1 /video/thumb/1444107854.jpg
After executing this i got a file of 23k size, apparently as in log it only copy audio stream and no video is added in final output.
