Don't use the functions for searching substrings when all one is looking for is a char anyway. Given that there is already a standard library function for "find last occurence of a char in a string" also allows one to remove a custom loop.

The current parsing process for adaptation_sets does not guarantee every adaptation set to contain at least one stream, because the loop exits immediately as soon as the end of the string has been reached, without checking whether the currently active adaptation set group is lacking a stream. This would lead to segfaults lateron as the rest of the code presumed that every adaptation set contains a stream. This commit fixes this by erroring out when the last adaptation set group is incomplete. Signed-off-by: NAndreas Rheinhardt <andreas.rheinhardt@gmail.com>

The WebM DASH manifest muxer uses a loop to parse the adaptation_sets string (which is given by the user and governs which AVStreams are mapped to what adaptation set) and the very beginning of this loop is "if (*p == ' ') continue;". This of course leads to an infinite loop if the condition is true. It is true if e.g. the string begins with ' ' or if there are more than one ' ' between different adaptation set groups. To fix this, the parsing process has been modified to consume the space if it is at a place where it can legitimately occur, i.e. when a new adaptation set group is expected. The latter restriction implies that an error is returned if a space exists where none is allowed to exist. Signed-off-by: NAndreas Rheinhardt <andreas.rheinhardt@gmail.com>

The syntax of the adaptation_sets string by which the user determines the mapping of AVStreams to adaptation sets is "id=x,streams=a,b,c id=y,streams=d,e" (means: the streams with the indices a, b and c belong to the adaptation set with id x). Yet there was no check for whether these indices were actual numbers and if there is a number whether it really extends to the next ',', ' ' or to the end of the string or not. This commit adds a check for this. Signed-off-by: NAndreas Rheinhardt <andreas.rheinhardt@gmail.com>

In order to parse a number from a string, the WebM DASH manifest muxer would duplicate (via heap-allocation) the part of the string that contains the number, then read the number via atoi() and then free the duplicate again. This has been replaced by simply using strtoll() (which in contrast to atoi() has defined behaviour when the number is not representable).

This change makes it possible for child encoders to define custom profile option names which can be used for setting the AVCodecContext->profile. Also rename unit name to something rather unique, so it won't be used elsewhere. Signed-off-by: NMarton Balint <cus@passwd.hu>

This will be used for AVCodecContext->profile. By specifying constants in the encoders we won't have to use the common AVCodecContext options table and different encoders can use the same profile name even with different values. Signed-off-by: NMarton Balint <cus@passwd.hu>

Move the copying of the frame to vos_data further up in the function, so that when writing the actual frame data for the first frame, it's clear that the stream really is in annex b format, for the cases where we create extradata from the first frame. Alternatively - we could invert the checks for bitstream format. If extradata is missing, we can't pretend that the bitstream is in mp4 form, because we can't even know the NAL unit length prefix size in that case. Also avoid creating extradata for AVC intra. If the track tag is an AVC intra tag, don't copy the frame into vos_data - this matches other existing cases of how vos_data and TAG_IS_AVCI interact in other places.

EAGAIN is returned when input is provided but can't be consumed. The filtering process is unaffected in this case, and the function will be able to consume new input after retrieving filtered packets with av_bsf_receive_packet(). Remove the line about empty packets never failing added in 41b05b84 while at it. Even if it's currently the case, it unnecessarily constrains the API and could be changed in the future in case it needs to be extended. The user should always check for errors and never expect a call to never fail. Reviewed-by: NDerek Buitenhuis <derek.buitenhuis@gmail.com> Signed-off-by: NJames Almer <jamrial@gmail.com>

av_stream_get_side_data() tells the caller whether a stream has side data of a specific type; if present it can also tell the caller the size of the side data via an optional argument. The Matroska muxer always used this optional argument, although it doesn't really need the size, as the relevant side-data are not buffers, but structures. So change this. Furthermore, relying on the size also made the code susceptible to a quirk of av_stream_get_side_data(): It only sets the size argument if it found side data of the desired type. mkv_write_video_color() checks for side-data twice with the same variable for the size without resetting the size in between; if the second type of side-data isn't present, the size will still be what it was after the first call. This was not dangerous in practice, as the check for the existence of the second side-data compared the size with the expected size, so it would only be problematic if lots of elements were to be added to AVContentLightMetadata.

Some real-world sites use an authorization header with a bearer token; when combined with lengthy request parameters to identify the video segment, it's rather trivial these days to have a request body of more than 4k bytes. MAX_URL_SIZE is hard-coded to 4k bytes in libavformat/internal.h, and HTTP_HEADERS_SIZE is 4k as well in libavformat/http.h, so this patch increases the buffer size to 8k, as that is the default request body limit in Apache, and most other httpds seem to support at least as much, if not more.
