[FFmpeg-user] Ffmpeg logging

Re: [FFmpeg-user] HEVC acceleration
> You should probably also try with older FFmpeg versions... I tried with an older version of ffmpeg (3.4.7), and it works. The issue is that I don't see any difference when using ffmpeg with and without the "-c:v hevc_v4l2m2m" option. This means that the HEVC accelerator is not enabled. Am I right? Am I missing something in the command line of ffmpeg?

[FFmpeg-user] How to decode an HEVC content with Hardware video decoder using FFmpeg
Hello, I would like to decode an HEVC content with Hardware video decoder on a board running on Android. I successfully cross-compiled FFmpeg to be run on Android. Now I want to enable Hardware acceleration of FFmpeg. I tried the option: " *--enable-hwaccel=auto*" but it seems like it has no effect. I checked the output of "./configure" command line, and there is no "hwaccel". Could anyone point me to a solution how to enable HEVC Hardware video decoding?

I need *ffplay*, because when decoding a video it gives how many frames are dropped. This is an important metric I need to evaluate video decoding.

Yes exactly. > ffplay does not work > with video via ssh which I don't consider very worrying. This time, I am connecting the board directly to the screen via Micro-HDMI, and I got the same issue. That's why, I am sure that problem didn't come from ssh connection. > Anything wrong with using ffmpeg FFmpeg works fine, without any problem. But, it can not do anything to reach the requested framerate (fps). For example, if a video is encoded at 25 fps, FFmpag can decode it at 5 fps if we use for example only one core, or at 60 fps if we use 8 cores. Therefore, FFmpeg decodes at the capacity of the hardware. I consider this as a constraint, because I can not calculate miss rate which is an important metric to evaluate a video decoder. > You are doing performance tests, right? Yes, exactly. Thank you.

Re: [FFmpeg-user] why ffplay cannot decode a sequence that can be decoded by ffmpeg
> In this case, ffplay is the wrong tool for you, ffmpeg -i input -an -f null - > may be a better idea. FFmpeg decodes a video depending on the hardware capacities, i.e., a video of 10 sec may be decoded in more than 1 mn or in only 5 sec. Therefore, FFmpeg doesn't incur miss rate (all frames are decoded and no one is dropped). To be clear, in my experiments, I want to evaluate video decoding using FFmpeg while running on multi-core. *Question:* Is there a way to decode a video using FFmpeg at a certain fps (e,g,, 25 fps) independently of the hardware capacities (*m**aybe by adding some code to FFmpeg and rebuilding it*). Of course, we will get different qualities, i.e., for example using 2 cores we will get 100 dropped frames whereas using 4 cores we will get only 5 dropped frames. > Frames per second is > available from ffprobe, right? Yes, it gives the fps at which it is encoded. In my experiments, I need the fps while decoding the video. It is different because it depends on the hardware performance. > -f null /dev/null as I understood, this parameter allows to throw the decoded frames, i.e., the decoded frames are lost.

no change over the time. The same decoding process quality (bad) until the
end of the video.

I am using multi-core processor.
I don't know, I followed the reply of Moritz Barsnick.
Thank you.

[FFmpeg-user] ffplay doesn't decode hevc correctly
Hello, I am using *ffplay *to play back a video. 1) how can I get the details of decoding (fps, miss rate, time, etc) 2) how can decode *hevc *content ? I compiled ffmpeg with libx265. When I try to play back a video encoded with hevc, I can not decode it correctly, i.e. ffplay plays it very slowly as I don't see all the frames. I am using this command: ffplay -threads 8 Thank you in advance ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".

Re: [FFmpeg-user] Frame dropping
Thank you for your reply. The input video is encoded with hevc at 25 fps. I tries this command: ffmpeg -threads 1 -vsync drop -i -f null /dev/null I got this message in yellow: Encoder did not produce proper pts, making some up Unfortunately, I can not reach 25 fps while decoding, even with dropping frames. So I think that the option for "frame dropping" is not working !!

[FFmpeg-user] Frame dropping
Hello, could you tell me how to enable "frame dropping" while decoding with ffmpeg ?

Re: [FFmpeg-user] Asking for help about FFmpeg
Thank you for your reply.
Yes, I don't need an output video. I just want to decode a video at 25 fps
and then calculate the miss rate. So I don't want to skip anything.

[FFmpeg-user] Asking for help about FFmpeg
Hello, I am working on video decoding using FFmpeg. When I try to decode a video which is encoded with HEVC (using ffmpeg) at a certain fps (e.g fps=25), the result is a decoded video but at a different fps. How can I decode a video at exactly 25 fps, even if I get high miss rate ? I am using this command for decoding: ffmpeg -benchmark -i -f null out.null Please, any help is welcome.
