[FFmpeg-devel] [PATCH] lavd/avfoundation: uses a queue to buffer audio and video samples
From: Matthieu Bouron
Tries to avoid losing frames when frames are not consumed quickly enough.
Locking/Condition waiting is now performed with a NSConditionLock instead
of a pthread mutex/condition.
The first frames are not discarded anymore in the get_(video|audio)_config
functions.
Tries to improve issue #4437, however it looks like the avfoundation
screen recording is not necesseraly in sync with the display,
occasionally leading to duplicated frames or frames not being catched.
The issue can be reproduced with the following test case:
* play a video at 60fps, each frames of this video has its number
burnt in
* record screen at 60fps
The output capture could have a pattern similar to the following one:
* 0, 1, 2, 3, [...], 50, 50, 52, 53, [...], 100, 102, 102, 103, [...]
The code will now output a warning if the drop happens on the avdevice
side.

I was afraid someone would point out it's less than two years old. Jokes aside, missing_sample can go as well if you insist, while for the other two you mention do you have any other argument than being "widely used"? I believe we went over and over explaining why it's a good a idea to remove those, not sure how beneficial it is to iterate once again.

It compiles with vdpau and h264 _enabled_, so maybe ok.

Nit: the usual coding style for FFmpeg is to put braces on both the if
clause and the else clause if one of them needs them.
This version has a more severe problem: it stores everything sent by the
client without a limit if it is given in duplicated headers. A malicious
client could exhaust the server's memory by sending endless similar headers.
I strongly suggest to limit both the total number of different headers as
you already do and the (approximate) total size of the headers data.

Note: I write this mail assuming you intend to continue working on the
project in your free time. Of course, whether you decide to or not does not
affect the outcome of the GsoC evaluation.

You can use @float NOTE

Why that? You apparently don't care that avcodec_alloc_frame was deprecated less than two years ago. And anyway, doing these removals strictly according to the calendar doesn't make sense. The reason for keeping deprecated APIs is, as you say, that "downstream users need time to update their applications". For widely used APIs this naturally takes longer than for rarely used ones. > Jokes aside, missing_sample can go as well if you insist, Yes, I do insist that the decision which APIs get removed now and which are kept makes some kind of sense. Apropos, delaying FF_API_NOCONST_GET_NAME also doesn't make any sense, because API users can't adapt to that before it happened. > while for > the other two you mention do you have any other argument than being > "widely used"? That's a way better argument than your argument for FF_API_MISSING_SAMPLE. What's your argument for keeping the ones you suggested? In particular I'm interested in explanations for the following, unused APIs: [lavc] - FF_API_AC_VLC - FF_API_OLD_MSMPEG4 - FF_API_ASPECT_EXTENDED - FF_API_ARCH_ALPHA - FF_API_QSCALE_TYPE - FF_API_MB_TYPE - FF_API_FAST_MALLOC - FF_API_NEG_LINESIZES - FF_API_IDCT_XVIDMMX - FF_API_INPUT_PRESERVED - FF_API_AFD [lavfi] - FF_API_AVFILTER_OPEN - FF_API_AVFILTER_INIT_FILTER [lavu] - FF_API_OPT_TYPE_METADATA - FF_API_DLOG > I believe we went over and over explaining why it's a > good a idea to remove those, not sure how beneficial it is to iterate > once again. Let me try to phrase it differently: If it's a good idea to remove those, it's an even better idea to remove all those, which you suggested to delay, because they are much less used. But you didn't propose that. Why? Best regards, Andreas ___ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel

Doesn't this belong in cmdutils.c?
What was your rationale for placing it here?

Likewise, shouldn't this be in cmdutils_common_opts.h?
There is no OPT_EXIT option in this table; they are all in
cmdutils_common_opts.h.

cmdutils.c is shared for all ff* programs. -hwaccel is only supported in
ffmpeg.

For consistency, prefix with an opt_?
Also, you always return a 0, making return value useless.
I understand this is done to match the func_arg signature.
Maybe you could check the return value of printf?
I do note that almost none of ffmpeg is that meticulous about these things,
but check out:

Why?
I don't know about this and I might be naive here,
but isn't hardware acceleration useful for decoding as well?
In this case it would be relevant to at least ffplay as well as ffmpeg.

Absolutely zero calls to printf in FFmpeg are checked. Even if checking the result code can be more secure, it is way outside the scope of this patch.

Ok. Please place the function outside of all the opt_* stuff; since this is not setting options, it should not be in the middle of them. Otherwise, patch LGTM. > >> Maybe you could check the return value of printf? > > Absolutely zero calls to printf in FFmpeg are checked. Even if checking > the result code can be more secure, it is way outside the scope of this > patch. Perhaps. My point was not so much from the position of security, but program correctness: a non zero printf return should propagate to the exit code. You are right this is beyond this patch's scope. > > Timothy > ___ > ffmpeg-devel mailing list > ffmpeg-devel@ffmpeg.org > http://ffmpeg.org/mailman/listinfo/ffmpeg-devel ___ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
[FFmpeg-devel] HLS Stream on Kodi
I'm trying to run a HLS Live Stream on Kodi and I'm getting an error 403 after 5 minutes. Checking the wireshark capture I did realize that the ffmpeg requests aren't changing a cookie that is set on every response. Do you guys confirm that is a FFMpeg issue?
