* tools/python: add script to convert TensorFlow model (.pb) to native model ↵Guo, Yejun2019-07-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | (.model) For example, given TensorFlow model file espcn.pb, to generate native model file espcn.model, just run: python convert.py espcn.pb In current implementation, the native model file is generated for specific dnn network with hard-code python scripts maintained out of ffmpeg. For example, srcnn network used by vf_sr is generated with https://github.com/HighVoltageRocknRoll/sr/blob/master/generate_header_and_model.py#L85 In this patch, the script is designed as a general solution which converts general TensorFlow model .pb file into .model file. The script now has some tricky to be compatible with current implemention, will be refined step by step. The script is also added into ffmpeg source tree. It is expected there will be many more patches and community needs the ownership of it. Another technical direction is to do the conversion in c/c++ code within ffmpeg source tree. While .pb file is organized with protocol buffers, it is not easy to do such work with tiny c/c++ code, see more discussion at http://ffmpeg.org/pipermail/ffmpeg-devel/2019-May/244496.html. So, choose the python script. Signed-off-by: Guo, Yejun <yejun.guo@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | when the last offsets in the stco atom are close to 4GB, the addition of the moov atom size can overflow, causing corruption near the end of the mp4 file. this patch upgrades all stco atoms to co64 when such an edge case is detected. in order to accomplish this, the implementation was changed to walk the atom tree, instead of searching for the strings 'stco'/'co64'. this was required since when an stco atom is changed to co64, its size changes, and the sizes of all containing atoms (moov, trak, etc.) have to be updated as well.

* | avcodec/allcodecs: Provide empty codec_list in allcodecs when ossfuzz is usedMichael Niedermayer2018-05-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The last workaround is not sufficient to make oss fuzz work with the iterate API as it did not provide a FFmpeg that external libs can be linked to. This patch does not fully restore the pre iterate functionality. My attempts to do this have so far failed. The problem with this solution is that it renders the fuzzers virtual system ffmpeg (libs) non functional. Which differs from a real system compared to the virtual system tested by the fuzzer. It should theoretically not matter as the system ffmpeg wouldnt be used. But with more cases being fuzzed we likely will hit a case where a external lib is involved and it does matter ... Working around this may be possible with weak symbols but so far my attempts failed Alternatively multiple ffmpeg could be built, this becomes messy though quickly as they need to be all linked together. That is we need a FFmpeg that has the iterate API modified so it can work with the resources available to ossfuzz. And at the same time we need a ffmpeg that has its full functionality for any external libs which use ffmpeg and are used by ffmpeg. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
