fftools/ffprobe : add analyze_frames option for CC and grain detection
8 décembre 2024, par Marth64fftools/ffprobe : add analyze_frames option for CC and grain detection
Currently, ffprobe has two stream-level fields that do not work,
closed_captions and film_grain).Their value is always 0 because ffprobe cannot access the internal
codec properties when it is setting up its stream contexts.In this commit, add the new option -analyze_frames to ffprobe,
allowing the user to read frames up to the interval they have defined
and fill these fields based on what is exposed in AVPacketSideData.Additionally, in the same commit, don't write these fields to
the output unless analyze_frames is enabled. Finally, fix the
FATE test refs accordingly and update the docs.Signed-off-by : Marth64 <marth64@proxyid.net>

VLC dead input for RTP stream
27 mars, par CaptainCheeseI'm working on creating an rtp stream that's meant to display live waveform data from Pioneer prolink players. The motivation for sending this video out is to be able to receive it in a flutter frontend. I initially was just sending a base-24 encoding of the raw ARGB packed ints per frame across a Kafka topic to it but processing this data in flutter proved to be untenable and was bogging down the main UI thread. Not sure if this is the most optimal way of going about this but just trying to get anything to work if it means some speedup on the frontend. So the issue the following implementation is experiencing is that when I run
vlc --rtsp-timeout=120000 --network-caching=30000 -vvvv stream_1.sdpwhere

% cat stream_1.sdp
v=0
o=- 0 1 IN IP4 127.0.0.1
s=RTP Stream
c=IN IP4 127.0.0.1
t=0 0
a=tool:libavformat
m=video 5007 RTP/AVP 96
a=rtpmap:96 H264/90000


I see (among other questionable logs) the following :


[0000000144c44d10] live555 demux error: no data received in 10s, aborting
[00000001430ee2f0] main input debug: EOF reached

[0000000142e083c0] macosx interface debug: Releasing IOKit system sleep blocker (37463)


This is sort of confusing because when I run
ffmpeg -protocol_whitelist file,crypto,data,rtp,udp -i stream_1.sdp -vcodec libx264 -f null -
I see a number logs about

[h264 @ 0x139304080] non-existing PPS 0 referenced
 Last message repeated 1 times
[h264 @ 0x139304080] decode_slice_header error
[h264 @ 0x139304080] no frame!


After which I see the stream is received and I start getting telemetry on it :

Not sure why VLC is turning me down like some kind of Berghain bouncer that lets nobody in the entire night.


I initially tried just converting the ARGB ints to a YUV420p buffer and used this to create the Frame objects but I couldn't for the life of me figure out how to properly initialize it as the attempts I made kept spitting out garbled junk.


Please go easy on me, I've made an unhealthy habit of resolving nearly all of my coding questions by simply lurking the internet for answers but that's not really helping me solve this issue.

Android ffmpeg. Linker command failed with exit code 1
8 juin 2017, par Wilsom SandersI’m trying to build ffmpeg static libraries and link them to an android project in order to implement a video player. Goal is to make a player capable of receiving video file from various sources similar to p2p file sharing networks. (target api is 21 level which is 1 level short from supposed official solution with MediaSource)
I managed to compile ffmpeg from this repo (all the code used as-is) but later i got stuck on a linking problem. Whenever I try to compile I get list of ffmpeg methods called in my code and a short eloquent message :
Linker command failed with exit code 1
I have no clue how to pass -v flag to the linker in android studio. Would be great if somebody hinted me that.
