#4451: Accept-Encoding parsing -------------------------------------+------------------------------------- Reporter: mnot | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- http.c parses the Accept-Encoding response header like this: """ if (!av_strcasecmp(tag, "Accept-Ranges") && !strncmp(p, "bytes", 5) && s->seekable == -1) { h->is_streamed = 0; } else if (!av_strcasecmp(tag, "Transfer-Encoding") && """ This means that if the string "bytes" shows up in the header at all, it will match -- making it error-prone if a range using that sequence of characters is ever defined (e.g., "newbytes" as recently proposed on the HTTP WG mailing list). The syntax isn't difficult to parse, it's a comma-separated list of tokens with optional whitespace (the same as several other headers): http://httpwg.github.io/specs/rfc7233.html#header.accept-ranges (found by Rodger Combs on the IETF HTTP WG mailing list) -- Ticket URL: <https://trac.ffmpeg.org/ticket/4451> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

For some files, the following error outputs and the output frames looks pixelated, looks like that the I frame for reference is missing. Such symptom lasts for several frames and will be corrected automatically. -> I think it is because there was a new I frame coming in, so the issue corrected automatically. When I tried to seek forward or backward, such error output and frame image goes wrong always, and corrected after several frames. I checked the reason for Discarding mismatching reference looks like the avctx-> format == 0x11, should be YUV, and the ref_list->parent->format == VDA_VLD.
