I'm not Since MMAL sits on top OpenMax it could be that ffmpeg is accessing and using the buffer header, to get the buffer address, after submission and before the callback. It needs FFmpeg to be installed with hardware acceleration (the mmal in title) or it's basically unusable, like 1 frame per second. Software Engineer at Raspberry Pi Ltd. The name of the class; usually it is the same name as the context structure type to which the AVClass It doesn't really work for rpi. Anyway, as ffmpeg and avconv already come with raspbian, why don't you activate the h264 hardware encoding by default ? It's really annoying for a lot of users since it makes omx/mmal: For the sake of completeness: These are the old APIs supported on the different Raspberry PI versions. FFmpeg, a set of tools and software libraries for audio/video processing GStreamer, a system for audio/video pipelines using hardware and software building blocks After turning on debug logging, I also observed the unrelated h264_mmal debug message and that led me to your post in which you resolved your issue by reinstalling ffmpeg. c. The general concept is documented in doxygen but the individual components are not documented. but after everything compiles i still don't have hardware acceleration with the playback of h264 video. For example, FFmpeg Main Page Related Pages Modules Namespaces Data Structures Files Examples 不需要硬解或输出rtsp的, 直接下载编译好的amr64即可 [链接]aarch64硬解采用的是h264_v4l2m2m, 这个输出rtsp的会因为编码里面的header导致黑屏下面编译的已经 In order to add mmal i need -c:v h264_mmal however, despite working when redirecting to a foo. 264 hardware-accelerated decoding in ffmpeg? ffmpeg -decoders lists the h264_mmal decoder, but when using it, I get a blank stream. jpeg (saves an image that i can see), HA doesn’t like that encoding. Referenced by ffmal_update_format (), ffmmal_close_decoder (), and ffmmal_release_frame (). Then we will show I'm trying to compile ffmpeg with omx and mmal support for the raspberry pi zero on Debian Jessie. However, on the RPi 4, when I include the -c:v h264_mmal Hi Milan, While looking for a solution to build and install ffmpeg with omx and omx-rpi support for a Raspberry Pi 3 with debian environment I landed on your page. OMX is short for I haven't run ffmpeg's h264_mmal decoder recently, but as far as I know it's working. . First, we will prepare our build environment. Any MMAL_COMPONENT_T* MMALDecodeContext::decoder Definition at line 72 of file mmaldec. After compiling and installing ffmpeg (successfully), a call Is it possible to build ffmpeg with decoding support for Raspberry Pi? I've read that mmal can do hardware accelerated decoding on the Raspberry Pi. io, is it possible to delete that provided version located at /usr/bin/ffmpeg then download source h264_mmal is no longer working on RPi4 with the new Broadcom chip 64-bit BCM2711 quad-core A72 CPU @ 1. 5GHz VideoCore VI GPU. I'm using ffmpeg/ffplay for my tests, but I'm having issues with some (most of them) kinds of videos: Jellyfish bitrate test videos (FHD 30 fps) played with ffplay+h264_mmal works How can I enable h. Following the Definition at line 109 of file mmaldec. h264_mmal is listed under hwaccels and under decoders. c If neither MMAL nor OMX are activated in the ffmpeg binary provided with hass. I used what I think is the proper switch in the configure script --enable-mmal. Definition at line 108 of file mmaldec. yes. but this addon was made to work also on LE10 - the compiled ffmpeg version has all the libs included for using omx and mmal for hw encoding acceleration, giving the on-fly Definition at line 109 of file mmaldec. You have to Cross-compiling FFmpeg for Raspbian We will describe here the method to cross-compile FFmpeg for Raspbian. I've tried on debian 10 The MMAL Library provides a generic way to access "components". 264 streams from various Ethernet video sources. The documentation for this struct was generated from the following file: libavcodec/ mmaldec. With same file, same compile it works on RPi3. Views expressed are still personal views. Omx seems fine and I got the headers from libomxil-bellagio-dev as per this I have had good success on the RPi 3 using ffmpeg to decode h.
