* avcodec: Disable new iterate API for ossfuzzMichael Niedermayer2018-05-161-0/+5
| | | | | | | | | | | | | | | | | A few days ago ossfuzz stoped testing new FFmpeg as it run out of diskspacee https://oss-fuzz-build-logs.storage.googleapis.com/index.html An alternative would be to revert the API. This changes for example -rwxr-x--- 1 michael michael 144803654 May 14 12:54 tools/target_dec_ac3_fixed_fuzzer* to -rwxr-x--- 1 michael michael 30333852 May 14 12:51 tools/target_dec_ac3_fixed_fuzzer* Which should massively decrease space requirements Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* lavc: prefer the mp3float decoder to the mp3 decoderRostislav Pehlivanov2018-04-011-3/+3
| | | | | | | | | On modern x86 systems its around 2x faster. For systems without FPUs it'll be slower, but our policy is to prefer floating point implementations and to let users decide what's best (or just not compile them on systems without FPUs).

* | avcodec: Implement mpeg4 nvdec hwaccelPhilip Langdale2017-11-201-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This was predictably nightmarish, given how ridiculous mpeg4 is. I had to stare at the cuvid parser output for a long time to work out what each field was supposed to be, and even then, I still don't fully understand some of them. Particularly: vop_coded: If I'm reading the decoder correctly, this flag will always be 1 as the decoder will not pass the hwaccel any frame where it is not 1. divx_flags: There's obviously no documentation on what the possible flags are. I simply observed that this is '0' for a normal bitstream and '5' for packed b-frames. gmc_enabled: I had a number of guesses as to what this mapped to. I picked the condition I did based on when the cuvid parser was setting flag. Also note that as with the vdpau hwaccel, the decoder needs to consume the entire frame and not the slice.
* | avcodec: Implement mpeg1 nvdec hwaccelPhilip Langdale2017-11-201-0/+1
| | | | | | | | | | Once I remembered that there's a separate decoder type for mpeg1, even though params struct is shared with mpeg2, everything worked.
* | avcodec: Implement mpeg2 nvdec hwaccelPhilip Langdale2017-11-181-0/+1
| | | | | | | | | | | | This is mostly straight-forward. The weird part is that it should just work for mpeg1, but I see corruption in my test cases, so I'm going to try and fix that separately.
* | avcodec: Implement vc1 nvdec hwaccelPhilip Langdale2017-11-141-0/+2
| | | | | | | | | | This hwaccel is interesting because it also works for wmv3/9 content, which is not supported by the nvidia parser used by cuviddec.
