FFmpeg Reader failed to find timing reference frame #15

Closed skoulik closed 3 years ago

skoulik commented 9 years ago

Hi, This is a follow-up of https://github.com/MrKepzie/openfx-io/issues/14 There is another video sample that produces unrecoverable error, but different from the previous one. http://www.neatvideo.com/files3/testkit.zip

Tested on 6834972c004c394a8bbea9665f6272a1ce95da59

Seems to work fine here, do you still have the same problem ? If so on which platform ?

skoulik commented 9 years ago

I've just checked on 643f2c8d1cf2fe926534abe11267edd6aa5f2a9f, the issue is still reproducible on Windows 7, 64 bit. Also reproducible with Natron 1.1 64 bit for windows: Add the clip to the graph with a Reader and cycle through the first 2-4 frames, you'll see the error message. The preview is black. With Natron 1.2.1 64 bit for windows the issue us still there, but the error message is not persistent, I can see it flashing for a moment when I cycle through the first 10 frames. The preview is black.

Have you tried using the snapshots of Natron 2.0 ? It’s currently building but binaries should be back online for windows in about an hour.

Unfortunately, I am not building Natron. Here is a trace captured with

define TRACE_DECODE_PROCESS 1

define TRACE_FILE_OPEN 1

hope, this helps 1 streams: FFmpeg stream index 0: Video decoder "mpeg1video" opened ok, getting stream properties: Timebase=1/90000 s/tick Duration=212400 ticks, 2.36 s BitDepth=4 NumberOfComponents=3 Framerate=25/1, 25 fps Image size=1280x720 Aspect ratio (from codec)=1 Determining stream start PTS: Obtained from AVStream::start_time=41667 ticks, 0.462967 s Determining stream frame count: Obtained from AVFormatContext::duration & framerate=59 1 streams: FFmpeg stream index 0: Video decoder "mpeg1video" opened ok, getting stream properties: Timebase=1/90000 s/tick Duration=212400 ticks, 2.36 s BitDepth=4 NumberOfComponents=3 Framerate=25/1, 25 fps Image size=1280x720 Aspect ratio (from codec)=1 Determining stream start PTS: Obtained from AVStream::start_time=41667 ticks, 0.462967 s Determining stream frame count: Obtained from AVFormatContext::duration & framerate=59 1 streams: FFmpeg stream index 0: Video decoder "mpeg1video" opened ok, getting stream properties: Timebase=1/90000 s/tick Duration=212400 ticks, 2.36 s BitDepth=4 NumberOfComponents=3 Framerate=25/1, 25 fps Image size=1280x720 Aspect ratio (from codec)=1 Determining stream start PTS: Obtained from AVStream::start_time=41667 ticks, 0.462967 s Determining stream frame count: Obtained from AVFormatContext::duration & framerate=59 1 streams: FFmpeg stream index 0: Video decoder "mpeg1video" opened ok, getting stream properties: Timebase=1/90000 s/tick Duration=212400 ticks, 2.36 s BitDepth=4 NumberOfComponents=3 Framerate=25/1, 25 fps Image size=1280x720 Aspect ratio (from codec)=1 Determining stream start PTS: Obtained from AVStream::start_time=41667 ticks, 0.462967 s Determining stream frame count: Obtained from AVFormatContext::duration & framerate=59 mov64Reader=00000000056880A0::decode(): frame=0, videoStream=0, streamIdx=0 Next frame expected out=-1, Seeking to desired frame Next frame expected in=unknown, Read OK, Packet data: PTS=52467, DTS=41667, Duration=3600, KeyFrame=0, Corrupt=0, StreamIdx=0, PktSize=137744, Relevant stream In seek (0), landing frame not found (landed after target at 3), can't seek before start, PTSs present, giving up !!ERROR: FFmpeg Reader failed to find timing reference frame, possible file corruption <-validPicture=0 for frame 0

Natron 2 binaries are released as snapshots at every commit, see https://natron.inria.fr/snapshots/

Tried Natron-03a73abe1eeeda2d178436f649df278d4a5677c7 for Windows 64 bit. The preview/playback or readers seem to be broken. Only first frame of the videos is displayed on preview. Preview does not refresh when I move cursor throu the timeline. Reproducible on any video I've tried, not only the one mentioned above.
