Hi,
I have installed libav from source with libx264 encoder.
I installed it in below way-
./configure --enable-gpl --enable-libx264
make
make install
Then I have tried to generate the m3u8 file by below command-
$avconv -i /home/mangospring/Downloads/original/sample.m4v -strict
experimental -acodec aac -c:v libx264 -hls_time 10 -hls_list_size 32767
/home/mangospring/Downloads/original/sample.m3u8
Which generates the m3u8 files with ts files. but the ts file generated is
of mpe2 video codec and mpeg4 audio codec. where generated video file codec
must be of H264 which was not.
PFA the output of the above command as well as orginal and converted file.
Could you please let me know if i missed any parameter or did i missing
anything while installation?
