Hi, I’m trying to use the Libavformat library in order to extract the plain h264 video stream from a audio video container format. I’ve used the remuxing.c example as a reference.
I want to support partial writes to the output context holding the extracted h264 video stream. I’m using a custom memory based AVIO, without seek support (unseekable). When returning a smaller amount of bytes then passed to the AVIO write_frame() callback, I would expect from the write callback to be called again with the rest of the data I didn’t read. In practice I saw that I’m getting new data for the next write callback. I wondered if I must support seek() for achieving partial write()s from AVIO. Am I missing something? Any insight is appreciated. Thanks -- Idan Freiberg Mobile: +972-52-2925213
