Hi, i have a simple program that reads all video packets from a file, decodes them into a frame and prints the corresponding timestamps. This works fine.
Output (test.avi): packet.pts=0 => frame.pts=0 packet.pts=1 => frame.pts=1 packet.pts=2 => frame.pts=2 packet.pts=3 => frame.pts=3 packet.pts=4 => frame.pts=4 packet.pts=5 => frame.pts=5 packet.pts=6 => frame.pts=6 when i use the avformat_find_stream_info() function in advance, which is reading some packets to determine information about the streams, the first packets are not decoded successfully and the following decoded frames got a "shifted" timestamp. Output (test.avi): packet.pts=0 => FRAME NOT FINISHED packet.pts=1 => FRAME NOT FINISHED packet.pts=2 => FRAME NOT FINISHED packet.pts=3 => FRAME NOT FINISHED packet.pts=4 => frame.pts=0 packet.pts=5 => frame.pts=1 packet.pts=6 => frame.pts=2 i guess the internal packet buffer is not flushed correctly after avformat_find_stream_info(). I already tried to free the packet_buffer and raw_packet_buffer in AVFormatContext, but this didn't worked. So any suggestions how to fix this without closing and re-opening the file?
