  • ffmpeg minimal requirements configuration for encoding and decoding h264 files

    14 novembre 2013, par TheSquad

    I'm trying to compile ffmpeg with minimal requirements in order to encode/decode with h264.

    So far my command line configuration is :

    ./configure --disable-yasm --disable-everything --enable-encoder=libx264 --enable-encoder=libfaac --enable-decoder=h264 --enable-muxer=h264 --enable-demuxer=h264 --enable-parser=h264 --enable-protocol=file

    once compiled, I try this :

    ./ffmpeg -i ~/Dropbox/TestFile.mov -vcodec libx264 test.mp4

    but I get an error :

    This is probably coming from the fact that I have forgot something to enable on the ffmpeg configuration... But I can't found out what.

  • Decoding an elementary HEVC stream using ffmpeg

    22 novembre 2013, par Zax

    I have successfully compiled and installed FFMPEG_2.1 from source code. I know that ffmpeg from version 2.1 onwards supports HEVC decoder. I have generated a .bin file using HM 10.0 and HM 11.0 HEVC reference code.

    However, when i give this bin file as an input to the ffmpeg i get an Input/output Error.

    The command that i have used is given below :

    ffmpeg -i Johnny_1280x720_60qp22.bin out.yuv

    The output of the above command is as shown below :
