[Libav-user] Change libx264 profile

[Valeriy Shtoma]

Hi to all,

Tell me, please, how to change libx264 profile and level? I tried:

av_dict_set(&libx264opt, "profile:v", "high", 0);
av_dict_set(&libx264opt, "level", "41", 0);

or

av_dict_set(&libx264opt, "profile", "high", 0);
av_dict_set(&libx264opt, "level", "41", 0);

or

av_dict_set(&libx264opt, “vprofile", "high", 0);
av_dict_set(&libx264opt, "level", "41", 0);

or

enc_ctx->profile = FF_PROFILE_H264_HIGH_422;
enc_ctx->level = 41;

I took as a base a file transcoding.c, and try to change profile and 
level of encoder, but at the end it’s all the same:

What have I done wrong? Thanks ;)
