In some corner cases (see #6802), it can be beneficial to use a larger stream buffer size. Use this as argument to rewrite everything for no reason. Turn stream.c itself into a ring buffer, with configurable size. The latter would have been easily achievable with minimal changes, and the ring buffer is the hard part. There is no reason to have a ring buffer at all, except possibly if ffmpeg don't fix their awful mp4 demuxer, and some subtle issues with demux_mkv.c wanting to seek back by small offsets (the latter was handled with small stream_peek() calls, which are unneeded now). In addition, this turns small forward seeks into reads (where data is simply skipped). Before this commit, only stream_skip() did this (which also mean that stream_skip() simply calls stream_seek() now). Replace all stream_peek() calls with something else (usually stream_read_peek()). The function was a problem, because it returned a pointer to the internal buffer, which is now a ring buffer with wrapping. The new function just copies the data into a buffer, and in some cases requires callers to dynamically allocate memory. (The most common case, demux_lavf.c, required a separate buffer allocation anyway due to FFmpeg "idiosyncrasies".) This is the bulk of the demuxer_* changes. I'm not happy with this. There still isn't a good reason why there should be a ring buffer, that is complex, and most of the time just wastes half of the available memory. Maybe another rewrite soon. It also contains bugs; you're an alpha tester now. |
