FFmpeg filtergraph memory leak
5 juillet 2017, par Leif AndersenI have an FFmpeg program that :
- Demuxes and decodes a video file.
- Passes it through a filtergraph
- encodes and muxes the new video.
The filtergraph itself is rather complex, and can be run directly from the command line as such :
ffmpeg -i demo.mp4 -filter_complex \
"[audio3]atrim=end=30:start=10[audio2];\
[video5]trim=end=30:start=10[video4];[audio2]anull[audio6];\
[video4]scale=width=1920:height=1080[video7];[audio6]anull[audio8];\
[video7]fps=fps=30[video9];[audio8]anull[audio10];\
[video9]format=pix_fmts=yuv420p[video11];\
[audio10]asetpts=expr=PTS-STARTPTS[audio12];\
[video11]setpts=expr=PTS-STARTPTS[video13];\
[audio15]concat=v=0:a=1:n=1[audio14];\
[video17]concat=v=1:a=0:n=1[video16];\
[audio12]afifo[audio15];[video13]fifo[video17];\
[audio14]afifo[audio18];[video16]fifo[video19];\
[audio18]anull[audio20];\
[video19]pad=width=1920:height=1080[video21];\
[audio20]anull[audio22];[video21]fps=fps=25[video23];\
[audio22]aformat=sample_fmts=fltp:sample_rates=44100:channel_layouts=stereo[fa];\
[video23]format=pix_fmts=yuv420p[fv];[0:a]afifo[audio3];\
[0:v]fifo[video5]" \
-map "[fv]" -map "[fa]" out.mp4I realize this is a massive filtergraph with a lot of no-op filters, it was autogenerated rather than being hand written. Here is a more cleaner version of the graph. (Its a graphviz file, you can run it in the command line or here.)
Anyway, when I run the program that uses this filtergraph my memory usage spikes. I end up using about 7 GB of RAM for a 30 second clip. However, when I run the program using the ffmpeg command above, it peaks out at about 600 MB of RAM. This causes me to believe that the problem is not the ungodly size of the filtergraph, but a problem with how my program is using it.
The program sets up the filtergraph (using
av_filter_parse_ptr, giving the filtergraph string shown above), encoder, muxer, decoder, and demuxer, then spawns two threads, one that sends frames into the filtergraph, and one that receives them. The frame that sends them looks something like :void decode () {
while(... more_frames ...) {
AVFrame *frame = av_frame_alloc();
... fill next frame of stream ...
av_buffersrc_write_frame(ctx, frame);
av_frame_free(&frame);
}
}(I have elided the
av_send_packet/av_receive_framefunctions as they don’t seem to be leaking memory. I have also elided the process of flushing the buffersrc as that won’t happen until the end, and the memory spikes long before that.)And the encoder thread looks similar :
void encode() {
while(... nodes_in_graph ...) {
AVFrame *frame = av_frame_alloc();
av_buffersink_get_frame(ctx, frame);
... ensure frame actually was filled ...
... send frame to encoder ...
av_frame_free(&frame);
}
}As with the decoder, I have elided the
send_frame/receive_packetcombo as they don’t seem to be leaking memory. Additionally I have elided the details of ensuring that the frame actually was filled. The code loops until the frame eventually does get filled.Every frame I allocate I fairly quickly deallocate. I additionally handled all of the error cases that the ffmpeg can give (Elided in the example).
I have also tried having only one frame for the encoder and one for the decoder (and calling
av_frame_unrefin each iteration of the loop).Am I forgetting to free something, or am I just using the calls to libavfilter incorrectly such that it has to buffer all of the data ? I don’t think the leak is caused by the memory graph because running it from the command line doesn’t seem to cause the same memory explosion.
FWIW, the actual code is here, although its written in Racket. I do have a minimal example that also seems to duplicate this behavior (modified from the
doc/example/filtering_video.cfile from the ffmpeg code :#include
#include <libavcodec></libavcodec>avcodec.h>

ffmpeg 1FPS extraction call spits out infinite images until disk is bricked on poorly-encoded movie
12 juillet 2017, par John AllardThis is one of the oddest things I’ve ever seen while using ffmpeg.
This is the scenario - we are getting video footage from a IONODE ION-E100 encoder, the footage is encoded in h264. I can view the footage fine in VLC, and I can copy it over to another video using
ffmpegand-c:v copy. The issue arises when I try and extract one FPS from the movie using the following command :ffmpeg -i testmovie.mp4 -r 1 -vf 640:-2 -q:v 18 -loglevel error /tmp/tmp/extraction_%04d.jpegWhat this should do is go through the movie and extract one frame per second, then dump the frames to the files
/tmp/tmp/extraction_0001.jpeg, /tmp/tmp/extraction_0002.jpeg, ..., /tmp/tmp/extraction_000X.jpeg. It should end when it reaches the end of the video.Now the odd thing that happens when I run this command is that it will run in a tight loop, writing tens or hundreds of thousands of images to the disk until the disk is full at which point the command fails. All of the extracted images are the exact same as one another.
Here is the ffmpeg stats output on the video
