* avcodec/v4l2_m2m_enc: Check encoder pix_fmt matches pix_fmt on deviceAndriy Gelman2019-12-27
| | | | | | | | | | | | | | | | | | | Fixes #8079 During initialization of a v4l2m2m device, the configured pix_fmt can be different to the pix_fmt of the encoder (i.e. avctx->pix_fmt). For example on the Odroid XU4: ./ffmpeg -f lavfi -i yuvtestsrc -codec:v h264_v4l2m2m out.h264 will configure the v4l2 encoder to pix_fmt nv21, whereas the input frames will be yuv444p. This commit checks that the configured v4l2 pix_fmt on device is the same as avctx->pix_fmt. If they are different the initialization fails and an error is returned. Tested on RPI4 and Odroid XU4.

* avformat/microdvd: Use \n instead of \0 to end file headerAndreas Rheinhardt2019-12-27
| | | | | | | | | | | | | | | | | | | | Up until now, the microdvd demuxer uses av_strdup() to allocate the extradata from a string; its length is set to strlen() + 1, i.e. including the \0 at the end. Upon remuxing, the muxer would simply copy the extradata at the beginning, including the \0. This commit changes this by not adding the \0 to the size of the extradata; the muxer now delimits extradata by inserting a \n. This required to change the subtitles-microdvd-remux FATE-test. Furthermore, the extradata is now allocated with zeroed padding. The microdvd decoder is not affected by this, as it didn't use the size of the extradata at all, but treated it as a C-string.

* avformat/flvenc: Forward errors from allocating keyframe indexAndreas Rheinhardt2019-12-26
| | | | | | | | | | | While the function adding a new element to the keyframe index checked the allocation, the caller didn't check the return value. This has been changed. To do so, the return value has been changed to an ordinary ret instead of pb->error. This doesn't pose a problem, as write_packet() in mux.c already checks for write errors (since 9ad1e0c1).
