• FFmpeg : Green images from TS file

  5 septembre 2017, par Tatsiana

  I use ffmpeg to generate images from a TS file and at some places it generates green images. I checked a couple of ffmpeg versions. The issue reproduces on
  3.3.3, 2.8.11, 2.7.7, but doesn’t on 2.6.9.
  What might be the reason ?

  For example, the output of 2.8.11 :

      $ ffmpeg -ss 00:42:20 -i video.ts -frames:v 1 out_42_20.jpg -loglevel debug

• Cuda Memory Management : re-using device memory from C calls (multithreaded, ffmpeg), but failing on cudaMemcpy

  4 mars 2013, par Nuke Stollak

  I'm trying to CUDA-fy my ffmpeg filter that was taking over 90% of the CPU time, according to gprof. I first went from one core to OpenMP on 4 cores and got a 3.8x increase in frames encoded per second, but it's still too slow. CUDA seemed like the next natural step.

  I've gotten a modest (20% ?) increase by replacing one of my filter's functions with a CUDA kernel call, and just to get things up and running, I was cudaMalloc'ing and cudaMemcpy'ing on each frame. I suspected I would get better results if I weren't doing this each frame, so before I go ahead and move the rest of my code to CUDA, I wanted to fix this by allocating the memory before my filter is called and freeing it afterwards, but the device memory isn't having it. I'm only storing the device memory locations outside of code that knows about CUDA ; I'm not trying to use the data there, just save it for the next time I call a CUDA-aware function that needs it.

  Here's where I am so far :

  Environment : the last AMI Linux on EC2's GPU Cluster, latest updates installed. Everything is fairly standard.

  My filter is split into two files : vf_myfilter.c (compiled by gcc, like almost every other file in ffmpeg) and vf_myfilter_cu.cu (compiled by nvcc). My Makefile's link step includes -lcudart and both .o files. I build vf_myfilter_cu.o using (as one line)

  nvcc -I. -I./ -I/opt/nvidia/cuda/include $(CPPFLAGS) 
  
       -Xcompiler "$(CFLAGS)" 
  
        -c -o libfilter/vf_myfilter_cu.o libfilter/vf_myfilter_cu.cu

  When the variables (set by configure) are expanded, here's what I get, again all in one line but split up here for easier reading. I just noticed the duplicate include path directives, but it shouldn't hurt.

  nvcc -I. -I./ -I/opt/nvidia/cuda/include -I. -I./ -D_ISOC99_SOURCE 
  
      -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -D_POSIX_C_SOURCE=200112
  
      -D_XOPEN_SOURCE=600 -DHAVE_AV_CONFIG_H 
  
      -XCompiler "-fopenmp -std=c99 -fomit-frame-pointer -pthread -g

                  -Werror=implicit-function-declaration -Werror=missing-prototypes 
  
                  -Werror=vla " 
  
      -c -o libavfilter/vf_myfilter_cu.o libavfilter/vf_myfilter_cu.cu

  vf_myfilter.c calls three functions from vf_myfilter_cu.cu file which handle memory and call the CUDA kernel code. I thought I would be able to save the device pointers from my memory initialization, which runs once per ffmpeg run, and re-use that space each time I called the wrapper for my kernel function, but when I cudaMemcpy from my host memory to my device memory that I stored, it fails with cudaInvalidValue. If I cudaMalloc my device memory on every frame, I'm fine.

  I plan on using pinned host memory, once I have everything up in CUDA code and have minimized the number of times I need to return to the main ffmpeg code.

  Steps taken :

  First sign of trouble : search the web. I found Passing a pointer to device memory between classes in CUDA and printed out the pointers at various places in my execution to ensure that the device memory values were the same everywhere, and they are. FWIW, they seem to start around 0x90010000.

  ffmpeg's configure gave me -pthreads, so I checked to see if my filter was being called from multiple threads according to how can I tell if pthread_self is the main (first) thread in the process ? and checking syscall(SYS_gettid) == getpid() to ensure that I'm not calling CUDA from different threads—I'm indeed in the primary thread at every step, according to those two funcs. I am still using OpenMP later around some for loops in the main .c filter function, but the calls to CUDA don't occur in those loops.

  Code Overview :

  ffmpeg provides me a MyfilterContext structure pointer on each frame, as well as on the filter's config_input and uninit routines (called once per file), so I added some *host_var and *dev_var variables (a few of each, float and unsigned char).

  There is a whole lot of code I skipped for this post, but most of it has to do with my algorithm and details involved in writing an ffmpeg filter. I'm actually using about 6 host variables and 7 device variables right now, but for demonstration I limited it to one of each.

  Here is, broadly, what my vf_myfilter.c looks like.

  // declare my functions from vf_myfilter_cu.cu 
  
  extern void cudaMyInit(unsigned char **dev_var, size_t mysize);
  
  extern void cudaMyUninit(unsigned char *dev_var);
  
  extern void cudaMyFunction(unsigned char *host_var, unsigned char *dev_var, size_t mysize);
  
  
  
  // part of the MyFilterContext structure, which ffmpeg keeps track of for me.
  
  typedef struct {
  
      unsigned char *host_var;
  
      unsigned char *dev_var;
  
  } MyFilterContext;
  
  
  
  // ffmpeg calls this function once per file, before any frames are processed.
  
  static int config_input(AVFilterLink *inlink) {
  
          // how ffmpeg passes me my context, fairly standard.
  
      MyfilterContext * myContext = inlink->dst->priv; 
  
          // compute the size one video plane of one frame of video
  
      size_t mysize = sizeof(unsigned char) * inlink->w * inlink->h;
  
          // av_mallocz is a malloc wrapper provided and required by ffmpeg
  
      myContext->host_var = (unsigned char*) av_mallocz(size);
  
          // Here's where I attempt to allocate my device memory.
  
      cudaMyInit( & myContext->dev_var, mysize);  
  
  }
  
  
  
  // Called once per frame of video
  
  static int filter_frame(AVFilterLink *inlink, AVFilterBufferRef *frame) {
  
      MyFilterContext *myContext = inlink->dst->priv;
  
  
  
      // sanity check to make sure that this isn't part of the multithreaded code
  
      if ( syscall(SYS_gettid) == getpid() ) 
  
          av_log(.... ); // This line never runs, so it's not threaded?
  
  
  
      // ...fill host_var with data from frame, 
  
      // set mysize to the size of the buffer
  
  
  
      // Call my wrapper function defined in the .cu file
  
      cudaMyFunction(myContext->host_var, myContext->dev_var, mysize);
  
  
  
      // ... take the results from host_var and apply them to frame
  
      // ... and return the processed frame to ffmpeg 
  
  }
  
  
  
  // called after everything else has happened:  free up the memory.
  
  static av_cold void uninit(AVFilterContext *ctx) {
  
      MyFilterContext *myContext = ctx->priv;
  
      // free my host_var
  
      if(myContext->host_var!=NULL) {
  
          av_free(myContext->host_var);
  
          myContext->host_var=NULL;
  
      }
  
      // free my dev_var
  
      cudaMyUninit(myContext->dev_var);
  
  }

  Here is, broadly, what my vf_myfilter_cu.cu looks like :

  // my kernel function that does the work.
  
  __global__ void myfunc(unsigned char *dev_var, size_t mysize) {
  
      // find the offset for this particular GPU thread to process
  
      // exit this function if the block/thread combo points to somewhere
  
      //     outside the frame
  
      // make sure we're less than mysize bytes from the beginning of dev_var
  
      // do things to dev_var[some_offset]
  
  } 
  
  // Allocate the device memory
  
  extern "C" void cudaMyInit(unsigned char **dev_var, size_t mysize) {
  
      if(cudaMalloc( (void**) dev_var, mysize) != cudaSuccess) {
  
          printf("Cannot allocate the memory\n");
  
      }
  
  }
  
  
  
  // Free the device memory.
  
  extern "C" void cudaMyUninit(unsigned char *dev_var) {
  
      cudaFree(dev_var);
  
  }
  
  
  
  // Copy data from the host to the device,
  
  // Call the kernel function, and 
  
  // Copy data from the device to the host.
  
  extern "C" void cudaMyFunction(
  
          unsigned char *host_var, 
  
          unsigned char *dev_var, 
  
          size_t mysize         ) 
  
  {
  
      cudaError_t cres;
  
  
  
      // dev_works is what I want to get rid of, but 
  
      // to make sure that there's not something more obvious going 
  
      // on, I made sure that my cudaMemcpy works if I'm allocating
  
      // the device memory in every frame.
  
      unsigned char *dev_works;  
  
      if(cudaMalloc( (void **) &dev_works, mysize)!=cudaSuccess) { 
  
          // I don't see this message
  
          printf("failed at per-frame malloc\n");
  
      }
  
  
  
      // THIS PART WORKS, copying host_var to dev_works
  
      cres=cudaMemcpy( (void *) dev_works, host_var, mysize, cudaMemcpyHostToDevice);
  
      if(cres!=cudaSuccess) {
  
          if(cres==cudaErrorInvalidValue) {
  
              // I don't see this message.
  
              printf("cudaErrorInvalidValue at per-frame cudaMemcpy\n");
  
          }
  
      }
  
  
  
      // THIS PART FAILS, copying host_var to dev_var
  
      cres=cudaMemcpy( (void *) dev_var, host_var, mysize, cudaMemcpyHostToDevice);
  
      if(cres!=cudaSuccess) {
  
          if(cres==cudaErrorInvalidValue) {
  
              // this is the error code that prints.

  Any ideas ?

• ffmpeg concatenation after using drawtext filter

  12 août 2016, par Sven Hoskens

  I’m fairly new to ffmpeg, but after a few days of searching on this issue, I’ve completely hit a brick wall. Any help would be appreciated.

  My use case : Our client wants to upload videos for multiple regions. Each video will be the same format, 1920x1080, mp4. For each region, they want to add a different image at the end of the video, for a few seconds. This image contains their logo, some additional info, and a variable code. They will enter this code alongside the uploaded video. The image stays the same, so is already present on the server.
  So basically, I have an input video, a video of an image, and a small code. I need to add this code to the video of the image (in a predefined position), and then I need to add the resulting video to the end of the input video. Once that is complete, I just need to output the video in 1920x1080 and in 1024x576.

  I have tried several things, but the concatenation step always fails with the manipulated video’s.

  Attempt 1

  In my first attempt, I used ffmpeg to create a video from an image, and add the text in the designated area.

  ffmpeg -y -f lavfi -i image.png -r 30 -t 10 -pix_fmt yuv420p -map 0:v -vf drawtext="fontfile=HelveticaNeue.dfont: text='GLNS/TEST/1234b': fontcolor=black: fontsize=20: box=1: boxcolor=white: boxborderw=7: x=179: y=805" imageVideo.mp4

  This command creates a .mp4 video of the correct size, with a duration of 10 seconds, and adds the text ’GLNS/TEST/1234b’ in the correct location.

  Next, I use the following command to concatenate the two videos. Both have the same resolution and codec.

  ffmpeg -f concat -safe 0 -i config.txt -vf scale=1920:1080 outputHD.mp4 -vf scale=1024:576 outputSD.mp4

  config.txt contains following :

  file my_input_file.mp4
  
  file ImageVideo.mp4

  This concatenation works with regular videos. However, when I use it with ImageVideo.mp4 (the one created by the first command) I get this error log :

  [mov,mp4,m4a,3gp,3g2,mj2 @ 0x7f86dc924600] Auto-inserting h264_mp4toannexb bitstream filtereed=0.509x

  Error while decoding stream #0:1: Invalid data found when processing input
  
  
  
  #this goes on for a few hundred lines

  The resulting output is identical to the input video, but does not contain the desired image video at the end.

  Attempt 2

  Since the above attempt didn’t work, I tried concatenating a video I let our designer make of the image with Adobe After Effects. This video was also saved as a .mp4 with the H264 codec. If I concatenate the input video and this one, I get a correct result. However, as soon as I add the code in the designated area with this command :

  ffmpeg -i new_image_video.mp4 -vf drawtext="fontfile=HelveticaNeue.dfont: text='GLNS/TEST/1234b': fontcolor=black: fontsize=20: box=1: boxcolor=white: boxborderw=7: x=179: y=805" -c:v libx264 imageVideo.mp4

  I get this error :

  The resulting output is identical to the input video, but does not contain the desired image video at the end.

  One thing I have noticed : When I inspect the video files on mac (Get info) they always contain these lines at ’More info’ :

  Dimensions: 1920 x 1080
  
  Codecs: H.264, AAC
  
  Color profile: HD(1-1-1)
  
  Duration: 01:42
  
  Audio channels: 2
  
  Last opened: Today 11:02

  However, the video’s which pass through the drawtext filter have this :

  Dimensions: 1920 x 1080
  
  Codecs: AAC, H.264
  
  Duration: 00:10
  
  Audio channels: 2
  
  Last opened: Today 11:07

  As you can see, there is no color profile entry, and the codecs have switched places. I assume this is related to my issue, but I can’t seem to find a fix for it.

  PS : The application will run in a php environment (Symfony). I noticed the concat command wasn’t available in the Symfony bundle for ffmpeg, so I’m using the regular terminal commands. I’ll execute these using php.

  EDIT
  Attempt 3

  On advise of a coworker, I tried converting the video to .avi and reconverting to .mp4, in the hopes this would lose any corrupted or extra info included by the drawtext filter. This spits out a completely different error.
