* avformat: Redo cleanup of demuxers upon read_header() failureAndreas Rheinhardt2021-07-07
| | | | | | | | | | | | | | | | | | | | If reading the header fails, the demuxer's read_close() function (if existing) is not called automatically; instead several demuxers call it via "goto fail" in read_header(). This commit intends to change this by adding an internal flag for demuxers that can be used to set on a per-AVInputFormat basis whether read_close() should be called generically after an error during read_header(). The flag controlling this behaviour needs to be added because it might be unsafe to call read_close() generally (e.g. this might lead to read_close() being called twice and this might e.g. lead to double-frees if av_free() is used instead of av_freep(); or a size field has not been reset after freeing the elements (see the mov demuxer for an example of this)).

* avformat: Add internal flags for AV(In|Out)putFormatAndreas Rheinhardt2021-07-07
| | | | | | | | | | | | | | | | Both AVInputFormat and AVOutputFormat currently lack an equivalent to AVCodec's caps_internal. E.g. if reading a header fails, each demuxer is currently required to clean up manually, which often means to just call the demuxer's read_close function. This could (and will) be done generically via an equivalent of FF_CODEC_CAP_INIT_CLEANUP. Because of the unholy ABI-relationship between libavdevice and libavformat adding such a flag is only possible when the ABI is open (despite the flag not being part of the public API), such as now. Therefore such a flag is also added to AVOutputFormat, despite there being no immediate use for it. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avformat/rtsp: Fix timeout optionAndriy Gelman2021-07-05
| | | | | | | | | | | | | | | | | | | | | | | 92c40ef882be115e72d2aa02f9032b7ce88f8537 added a listen_timeout option for sdp. This allowed a user to set variable timeout which was originally hard coded to 10 seconds. The commit used the initial_timeout variable to store the value. But this variable is shared with rtsp where it's used to infer a "listen" mode. Thus, the timeout value could not be set in rtsp, and the default value (initial_timeout = -1) would give 100ms timeout. This was attempted to be fixed in c8101aabee654f6d147a4d89f77fa73e18908610, which changed the meaning of initial_timeout = -1 to be an infinite timeout. However, it did not address the issue that the timeout could still not be set. Being able to set the timeout is useful because it allows to automatically reconfigure from a udp to tcp connection in the lower transport. In this commit this is fixed by using the stimeout variable to store the timeout value. Signed-off-by: Andriy Gelman <andriy.gelman@gmail.com>

* dashenc: Write out DASH manifest immediately in streaming modeKevin LaFlamme2021-06-14
| | | | | | | | | | | | | | When streaming mode is enabled with fMP4/CMAF for DASH output, the segment files are available to read by players as soon as the first byte is written instead of only after the file is fully written. The DASH manifest currently only gets written when the final write to the segment file occurs. This means that players cannot stream the first segment while it is being written. When -lhls is enabled with MP4 segments the HLS manifest is written immediately to advertise the in-flight segments. This change adds the same behavior for the DASH manifest so players can stream it immediately.
