Does IPP 8.0 support 640x480 resolution and 30FPS? I am using IPP 8.0 and I can make it work with 640x480, 15FPS, but it cannot work with 30FPS. Not sure why. SPS setting and SDP setting shall be right (SPS setting: Level_id 2.2, time_scale=60 & num_units_in_tick=1; SDP: framerate=30, Level_id=2.2, AS:4000).
Are you working on the IPP legacy sample audio_video_codec sample? As the article,
we remove the sample and move all media solution including the IPP video domain to media SDK : https://software.intel.com/en-us/tools-by-segment/media. You may try media SDK as replacement.
