-loglevel debug is showing that headers are being passed to fetch content from " ".But the problem is with getting remote key file i.e. -1500.key as it needs the same headers to get fetched and those same headers are not getting passed to remote key file url.I get this error :
This has currently no similarities with a valid ticket. Please test current FFmpeg git head - nothing else is supported here - and provide the command line you tested together with the complete, uncut console output. Please also explain why you want to provide specific html headers when reading from your file system.

On the other hand, the report is correct in so far that it does not seem possible to give ffmpeg command line options meant for e.g. protocols triggered "underneath". I.e. ffmpeg launches with a file protocol input which promotes to hls, but this in turn may trigger http protocol segments, yet ffmpeg will refuse to accept http protocol options on the command line.
Some muxers have ways of achieving this: The tee muxer has a special syntax, the segment muxer has "-segment_format_options", the dash muxer has "-format_options", the fifo muxer has "-format_opts". I don't see this for the hls demuxer (which is used in this example) though. The hls demuxer does expose some http protocol options via its own proxy options ("-http_persistent", "-http_multiple"), but "-headers" does not belong to those.
I am facing the same ffmpeg limitation with the current nightly for windows (20200309-608b8a8-win64-static).
If I supply ffmpeg an input m3u file located in my hard disk there is no way to customize http headers of subsequent network requests ffmpeg will make. This is also the case if the m3u is supplied via input pipe instead of input local file (for example with cat or echo in windows).
The reasons to need this feature could be diverse, for example you could need to download an m3u file to the hard disk and edit its content before feeding it to ffmpeg, using custom headers like you could if the m3u was located on the internet.
I could provide more detailed info or commands to replicate, but I think it is already clear what this feature request is about. Still if needed, let me know.
So, is there any chance this will be implemented, or is there already a way to achieve this with ffmpeg that I am not aware?
The libavformat library provides some generic global options, whichcan be set on all the muxers and demuxers. In addition each muxer ordemuxer may support so-called private options, which are specific forthat component.
Set probing size in bytes, i.e. the size of the data to analyze to getstream information. A higher value will enable detecting moreinformation in case it is dispersed into the stream, but will increaselatency. Must be an integer not lesser than 32. It is 5000000 by default.
Specify how many microseconds are analyzed to probe the input. Ahigher value will enable detecting more accurate information, but willincrease latency. It defaults to 5,000,000 microseconds = 5 seconds.
To ensure all the streams are interleaved correctly, libavformat willwait until it has at least one packet for each stream before actuallywriting any packets to the output file. When some streams are"sparse" (i.e. there are large gaps between successive packets), thiscan result in excessive buffering.
This field specifies the maximum difference between the timestamps of thefirst and the last packet in the muxing queue, above which libavformatwill output a packet regardless of whether it has queued a packet for allthe streams.
When shifting is enabled, all output timestamps are shifted by thesame amount. Audio, video, and subtitles desynching and relativetimestamp differences are preserved compared to how they would havebeen without shifting.
Flush the underlying I/O stream after each packet. Default is -1 (auto), whichmeans that the underlying protocol will decide, 1 enables it, and has theeffect of reducing the latency, 0 disables it and may increase IO throughput insome cases.
Set probing size, in bytes, for input duration estimation when it actually requiresan additional probing for PTS at end of file (at present: MPEG-PS and MPEG-TS).It is aimed at users interested in better durations probing for itself, or indirectlybecause using the concat demuxer, for example.The typical use case is an MPEG-TS CBR with a high bitrate, high video buffering andending cleaning with similar PTS for video and audio: in such a scenario, the largephysical gap between the last video packet and the last audio packet makes it necessaryto read many bytes in order to get the video stream duration.Another use case is where the default probing behaviour only reaches a single video frame which isnot the last one of the stream due to frame reordering, so the duration is not accurate.Setting this option has a performance impact even for small files because the probingsize is fixed.Default behaviour is a general purpose trade-off, largely adaptive, but the probing sizewill not be extended to get streams durations at all costs.Must be an integer not lesser than 1, or 0 for default behaviour.
allow non standardized experimental things, experimental(unfinished/work in progress/not well tested) decoders and encoders.Note: experimental decoders can pose a security risk, do not use this fordecoding untrusted input.
The exact semantics of stream specifiers is defined by theavformat_match_stream_specifier() function declared in thelibavformat/avformat.h header and documented in the(ffmpeg)Stream specifiers section in the ffmpeg(1) manual.
You can disable all the demuxers using the configure option--disable-demuxers, and selectively enable a single demuxer withthe option --enable-demuxer=DEMUXER, or disable itwith the option --disable-demuxer=DEMUXER.
This demuxer is used to demux APNG files.All headers, but the PNG signature, up to (but not including) the firstfcTL chunk are transmitted as extradata.Frames are then split as being all the chunks between two fcTL ones, orbetween the last fcTL and IEND chunks.
The timestamps in the files are adjusted so that the first file starts at 0and each next file starts where the previous one finishes. Note that it isdone globally and may cause gaps if all streams do not have exactly the samelength.
The duration of each file is used to adjust the timestamps of the next file:if the duration is incorrect (because it was computed using the bit-rate orbecause the file is truncated, for example), it can cause artifacts. Theduration directive can be used to override the duration stored ineach file.
This directive works best with intra frame codecs, because for non-intra frameones you will usually get extra packets before the actual In point and thedecoded content will most likely contain frames before In point too.
For each file, packets before the file In point will have timestamps less thanthe calculated start timestamp of the file (negative in case of the firstfile), and the duration of the files (if not specified by the durationdirective) will be reduced based on their specified In point.
Out point of the file. When the demuxer reaches the specified decodingtimestamp in any of the streams, it handles it as an end of file condition andskips the current and all the remaining packets from all streams.
This directive works best with intra frame codecs and formats where all streamsare tightly interleaved. For non-intra frame codecs you will usually getadditional packets with presentation timestamp after Out point therefore thedecoded content will most likely contain frames after Out point too. If yourstreams are not tightly interleaved you may not get all the packets from allstreams before Out point and you may only will be able to decode the earlieststream until Out point.
Metadata of the packets of the file. The specified metadata will be set foreach file packet. You can specify this directive multiple times to add multiplemetadata entries.This directive is deprecated, use file_packet_meta instead.
Introduce a stream in the virtual file.All subsequent stream-related directives apply to the last introducedstream.Some streams properties must be set in order to allow identifying thematching streams in the subfiles.If no streams are defined in the script, the streams from the first file arecopied.
Set the id of the stream.If this directive is given, the string with the corresponding id in thesubfiles will be used.This is especially useful for MPEG-PS (VOB) files, where the order of thestreams is not reliable.
If set to 1, reject unsafe file paths and directives.A file path is considered safe if itdoes not contain a protocol specification and is relative and all componentsonly contain characters from the portable character set (letters, digits,period, underscore and hyphen) and have no period at the beginning of acomponent.
If set to 1, every packet will contain the lavf.concat.start_time and thelavf.concat.duration packet metadata values which are the start_time andthe duration of the respective file segments in the concatenated outputexpressed in microseconds. The duration metadata is only set if it is knownbased on the concat file.The default is 0.
This demuxer presents all AVStreams found in the manifest.By setting the discard flags on AVStreams the caller can decidewhich streams to actually receive.Each stream mirrors the id and bandwidth properties from the as metadata keys named "id" and "variant_bitrate" respectively.
Underlying playback is handled by libdvdnav, and structure parsing by libdvdread.FFmpeg must be built with GPL library support available as well as theconfigure switches --enable-libdvdnav and --enable-libdvdread.
You will need to provide either the desired "title number" or exact PGC/PG coordinates.Many open-source DVD players and tools can aid in providing this information.If not specified, the demuxer will default to title 1 which works for many discs.However, due to the flexibility of the format, it is recommended to check manually.There are many discs that are authored strangely or with invalid headers. 152ee80cbc
