* avformat/aviobuf: don't reduce short seek thresholdAndriy Gelman2021-03-16
| | | | | | | | | | | | | | | | | | | | Commit 8c8e5d5286bf598a89ef9993a2cf6ea409d03a32 added a way to reduce seek time by waiting for the windowed tcp packets instead of creating a new socket connection. It implemented this by overwriting s->short_seek_threshold in avio_seek(). However, s->short_seek_threshold could already be set and be higher than the threshold set by the protocol (i.e. s->short_seek_threshold is set in ff_configure_buffers_for_index()). This new feature was only enabled for tls connections in 70d8077b795766e2486e6ec8110f22a97362d6d6. As in Ticket #9148 it reduced performance because instead of waiting to refill the AVIOContext buffers with an existing connections, a new HTTP request was often made instead. Fixes Ticket #9148.

* libavformat/hls: Reset options after open_url_keepalive() failsEd Martin2021-03-15
| | | | | | | | | | | | | | open_url_keepalive() unsets the options when it uses them, this includes the offsets for the Range: header. When using the HLS tag #EXT-X-BYTERANGE along with multiple files, the range options must be preserved after open_url_keepalive() returns EOF so that the new file can be opened. Failure to do this results in ignoring the #EXT-X-BYTERANGE tag and reading the wrong bytes of the file. To fix it, reset the options before calling io_open() following open_url_keepalive() reaching EOF Reviewed-by: Steven Liu <liuqi05@kuaishou.com>

* avformat/gopher: Add support for Gopher over TLSparazyd2021-03-11
| | | | | | | | | | | | | | | | This commit adds a "gophers" handler to the gopher protocol. gophers is a community-adopted protocol that acts the same way like normal gopher with the added TLS encapsulation. The gophers protocol is supported by gopher servers like geomydae(8), and clients like curl(1), clic(1), and hurl(1). This commit also adds compilation guards to both gopher and gophers, since now there are two protocols in the file it makes sense to have this addition.

For smaller amounts of data a tighter bound is possible but i saw no nice way to consider that and it seems also overkill to try to do it more fine grained for just this main(){ int64_t bits = 0; int bank = 256; int bitbank = 8; for(unsigned i = 0; i<1024*1024*1024*4U-100000;) { int word_size = bank-255; i += word_size; bits += bitbank; if (!(bank & (bank-1))) bitbank ++; bank++; if (bitbank > 16) { printf("BEST %f \n", 8.0 * i / bits ); bank = 256; bitbank = 8; } } } above assumes i remembered correctly how the algorithm works but the value was close to what actual compession of zeros gave Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/projects/ffmpeg Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
