I have a hevc all-intra bitstream in which each frame has 4(2x2) tiles(slices). My program can decode it using ffmpeg and render it using OpenGL. The decoding process is almost the same as this example. http://ffmpeg.org/doxygen/4.0/decode__video_8c_source.html
What I want is only one specific tile in each frame (for example, the second tile). In order to reduce the decoder load, I don't want to decode the other 3 tiles. If it is possible to decode only one specific tile(slice), please teach me how to do it. (I posted this question to StackOverFlow before, but received no answer. Someone advised me to post to this mailing list.) Thank you. _______________________________________________ Libav-user mailing list [email protected] https://ffmpeg.org/mailman/listinfo/libav-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
