Hi, I develop the player to decode the stream from the camera. My
program execution occurs on the device on ARM-architecture to improve
performance and use multi-threading.
avCodecContext->thread_count = 0;
avCodecContext->thread_type = FF_THREAD_SLICE | FF_THREAD_FRAME;
But on some cameras decoding occurs normally, while on others do not
If I add a flag
avCodecContext->flags2 |= CODEC_FLAG2_CHUNKS;
, then all the cells occurs decoding, but it turned off multithreading.
If not, I can use multi-threading for all streams. How better to
implement enable / disable multithreading?
