      avcodec/vc1: store zero MVs for all blocks in a MB · 8a4dbd3e
      Jerome Borsboom authored 
      Direct prediction for interlace frame B pictures references the mv in the
second block in an MB in the backward reference frame for the twomv case.
When the backward reference frame is an I frame, this value may be unset.

      avcodec/vc1: fix mquant calculation for interlace field pictures · c0402e1e
      Jerome Borsboom authored 
      For interlace field pictures s->mb_height indicates the height of the full
picture in MBs, i.e. the two fields combined. A single field is half this
size. When calculating mquant for interlace field pictures, the bottom edge
is the last MB row of the field.

      avcodec/allcodecs: Provide empty codec_list in allcodecs when ossfuzz is used · 42f40d36
      Michael Niedermayer authored 
      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.

      lavf/libssh: translate a read of 0 to EOF · 26892c76
      Jan Ekström authored 
      Yet another case of forgotten 0 =! EOF translation.

While the documentation for this specific synchronous read
function does not mention it, the documentation for
`sftp_async_read` documents it, as well as looking at the
implementation of this function leads one to find
`if (handle->eof) { return 0; }`.

      avformat/dashenc: Added a warning for incorrect segment name extension · ebf85d31
      Karthick Jeyapal authored 
      Applicable only to webm output format.
By default all the segment filenames end with .m4s extension.
When someone chooses webm output format, we recommend they also override the relevant segment name options to end with .webm extension. This patch will issue a warning for he same

      avformat/dashenc: Added option for Segment file format · 2efdbf73
      Karthick Jeyapal authored 
      Right now segment file format is chosen to be either mp4 or webm based on the codec format.
This patch makes that choice configurable by the user, instead of being decided by the muxer.

Also with this change per-stream choice segment file format(based on codec type) is not possible.
All the output audio and video streams should be in the same file format.
