    Stream #0:0: Video: png, pal8, 520x600, 7 fps, 7 tbr, 7 tbn, 7 tbc
Codec AVOption crf (Select the quality for constant quality mode) specified for output file #0 (/Users/shambala/tabrez/rgplyrx1/tmp/video_creator/manoj_test.mpg) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some encoder which was not actually used for any stream.
Codec AVOption preset (Set the encoding preset (cf. x264 --fullhelp)) specified for output file #0 (/Users/shambala/tabrez/rgplyrx1/tmp/video_creator/manoj_test.mpg) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some encoder which was not actually used for any stream.
Codec AVOption tune (Tune the encoding params (cf. x264 --fullhelp)) specified for output file #0 (/Users/shambala/tabrez/rgplyrx1/tmp/video_creator/manoj_test.mpg) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some encoder which was not actually used for any stream.
